Preamble. United States total public debt outstanding is $32.8 trillion and debt held by the public $25.9 trillion (https://fiscaldata.treasury.gov/datasets/debt-to-the-penny/debt-to-the-penny). The Net International Investment Position of the United States, or foreign debt, is $16.75 trillion at the end of IQ2023 (https://www.bea.gov/sites/default/files/2023-06/intinv123.pdf). The United States current account deficit is 3.3 percent of GDP in IQ2023, increasing from 3.2 percent in IVQ2022 (https://www.bea.gov/sites/default/files/2023-06/trans123.pdf). The Treasury deficit of the United States reached $2.8 trillion in fiscal year 2021 (https://fiscal.treasury.gov/reports-statements/mts/). Total assets of Federal Reserve Banks reached $8.1 trillion on Aug 23, 2023 and securities held outright reached $7.5 trillion (https://www.federalreserve.gov/releases/h41/current/h41.htm#h41tab1). US GDP nominal NSA reached $26.8 trillion in IIQ2023 (https://apps.bea.gov/iTable/index_nipa.cfm). US GDP contracted at the real seasonally adjusted annual rate (SAAR) of 1.6 percent in IQ2022 and contracted at the SAAR of 0.6 percent in IIQ2022, growing at 3.2 percent in IIIQ2022, growing at 2.6 percent in IVQ2022, growing at 2.0 percent in IQ2023 and growing at 2.4 percent in IIQ2023 (https://apps.bea.gov/iTable/index_nipa.cfm). Total Treasury interest-bearing, marketable debt held by private investors increased from $3635 billion in 2007 to $16,439 billion in Sep 2021 (Fiscal Year 2021) or increase by 352.2 percent (https://fiscal.treasury.gov/reports-statements/treasury-bulletin/). John Hilsenrath, writing on “Economists Seek Recession Cues in the Yield Curve,” published in the Wall Street Journal on Apr 2, 2022, analyzes the inversion of the Treasury yield curve with the two-year yield at 2.430 on Apr 1, 2022, above the ten-year yield at 2.374. Hilsenrath argues that inversion appears to signal recession in market analysis but not in alternative Fed approach. The Consumer Price index of the United States in Chart CPI-H increased 3.2 percent in Jul 2023 Relative to a Year Earlier, The Tenth Highest Since 8.9 percent in Dec 1981 was Followed by the Highest of 9.1 percent in Jun 2022, the Second Highest of 8.6 percent in May 2022, 8.5 percent in both Jul 2022 and Mar 2022, 8.3 percent in both Apr and Aug 2022, 8.2 percent in Sep 2022, 7.7 percent in Oct 2022, 7.1 percent in Nov 2022, 6.5 percent in Dec 2022, 6.4 percent in Jan 2023, 6.0 percent in Feb 2023, 5.0 percent in Mar 2023, 4.9 percent in Apr 2023, 4.0 percent in May 2023, 3.0 percent in Jun 2023 and 3.2 percent in Jul 2023.

Chart IV-16 of the Bureau of Labor Statistics provides 12-month percentage changes of the all items consumer price index from Jan 1991 to Dec 1996. Inflation collapsed during the recession from Jul 1990 (III) and Mar 1991 (I) and the end of the Kuwait War on Feb 25, 1991 that stabilized world oil markets. CPI inflation remained almost the same and there is no valid counterfactual that inflation would have been higher without monetary policy tightening because of the long lag in effect of monetary policy on inflation (see Culbertson 1960, 1961, Friedman 1961, Batini and Nelson 2002, Romer and Romer 2004). Policy tightening had adverse collateral effects in the form of emerging market crises in Mexico and Argentina and fixed income markets worldwide.

“In the period of the free coffee market 1857-1906, international coffee prices fluctuated in cycles of increasing amplitude. British export prices decreased at a low average rate, and physical exports of coffee by Brazil increased at the average rate of 2.9 percent per year. The income terms of trade of the coffee economy of Brazil improved at the average compound rate of 4.0 percent per year. But the actual rate must have been much higher because of drastic improvements in the quality of manufactures while the quality of coffee remained relatively constant,” Carlos Manuel Peláez, “The Theory and Reality of Imperialism in the Coffee Economy of Nineteenth-Century Brazil,” The Economic History Review, Second Series, Volume XXIX, No. 2, May 1976. 276-290. See Carlos Manuel Peláez, “A Comparison of Long-Term Monetary Behavior and Institutions in Brazil, Europe and the United States,” The Journal of European Economic History, Volume 5, Number 2, Fall 1976, 439-450, Presented at the Sixth International Congress of Economic History, Section on Monetary Inflation in Historical Perspective, Copenhagen, 22 Aug 1974.

In his classic restatement of the Keynesian demand function in terms of “liquidity preference as behavior toward risk,” James Tobin (http://www.nobelprize.org/nobel_prizes/economic-sciences/laureates/1981/tobin-bio.html) identifies the risks of low interest rates in terms of portfolio allocation (Tobin 1958, 86):

“The assumption that investors expect on balance no change in the rate of interest has been adopted for the theoretical reasons explained in section 2.6 rather than for reasons of realism. Clearly investors do form expectations of changes in interest rates and differ from each other in their expectations. For the purposes of dynamic theory and of analysis of specific market situations, the theories of sections 2 and 3 are complementary rather than competitive. The formal apparatus of section 3 will serve just as well for a non-zero expected capital gain or loss as for a zero expected value of g. Stickiness of interest rate expectations would mean that the expected value of g is a function of the rate of interest r, going down when r goes down and rising when r goes up. In addition to the rotation of the opportunity locus due to a change in r itself, there would be a further rotation in the same direction due to the accompanying change in the expected capital gain or loss. At low interest rates expectation of capital loss may push the opportunity locus into the negative quadrant, so that the optimal position is clearly no consols, all cash. At the other extreme, expectation of capital gain at high interest rates would increase sharply the slope of the opportunity locus and the frequency of no cash, all consols positions, like that of Figure 3.3. The stickier the investor's expectations, the more sensitive his demand for cash will be to changes in the rate of interest (emphasis added).”

Tobin (1969) provides more elegant, complete analysis of portfolio allocation in a general equilibrium model. The major point is equally clear in a portfolio consisting of only cash balances and a perpetuity or consol. Let g be the capital gain, r the rate of interest on the consol and r^e the expected rate of interest. The rates are expressed as proportions. The price of the consol is the inverse of the interest rate, (1+r^e). Thus, g = [(r/r^e) – 1]. The critical analysis of Tobin is that at extremely low interest rates there is only expectation of interest rate increases, that is, dr^e>0, such that there is expectation of capital losses on the consol, dg<0. Investors move into positions combining only cash and no consols. Valuations of risk financial assets would collapse in reversal of long positions in carry trades with short exposures in a flight to cash. There is no exit from a central bank created liquidity trap without risks of financial crash and another global recession. The net worth of the economy depends on interest rates. In theory, “income is generally defined as the amount a consumer unit could consume (or believe that it could) while maintaining its wealth intact” (Friedman 1957, 10). Income, Y, is a flow that is obtained by applying a rate of return, r, to a stock of wealth, W, or Y = rW (Friedman 1957). According to a subsequent statement: “The basic idea is simply that individuals live for many years and that therefore the appropriate constraint for consumption is the long-run expected yield from wealth r*W. This yield was named permanent income: Y* = r*W” (Darby 1974, 229), where * denotes permanent. The simplified relation of income and wealth can be restated as:

W = Y/r (1)

Equation (1) shows that as r goes to zero, r→0, W grows without bound, W→∞. Unconventional monetary policy lowers interest rates to increase the present value of cash flows derived from projects of firms, creating the impression of long-term increase in net worth. An attempt to reverse unconventional monetary policy necessarily causes increases in interest rates, creating the opposite perception of declining net worth. As r→∞, W = Y/r →0. There is no exit from unconventional monetary policy without increasing interest rates with resulting pain of financial crisis and adverse effects on production, investment and employment.

Inflation and unemployment in the period 1966 to 1985 is analyzed by Cochrane (2011Jan, 23) by means of a Phillips circuit joining points of inflation and unemployment. Chart VI-1B for Brazil in Pelaez (1986, 94-5) was reprinted in The Economist in the issue of Jan 17-23, 1987 as updated by the author. Cochrane (2011Jan, 23) argues that the Phillips circuit shows the weakness in Phillips curve correlation. The explanation is by a shift in aggregate supply, rise in inflation expectations or loss of anchoring. The case of Brazil in Chart VI-1B cannot be explained without taking into account the increase in the fed funds rate that reached 22.36 percent on Jul 22, 1981 (http://www.federalreserve.gov/releases/h15/data.htm) in the Volcker Fed that precipitated the stress on a foreign debt bloated by financing balance of payments deficits with bank loans in the 1970s. The loans were used in projects, many of state-owned enterprises with low present value in long gestation. The combination of the insolvency of the country because of debt higher than its ability of repayment and the huge government deficit with declining revenue as the economy contracted caused adverse expectations on inflation and the economy.  This interpretation is consistent with the case of the 24 emerging market economies analyzed by Reinhart and Rogoff (2010GTD, 4), concluding that “higher debt levels are associated with significantly higher levels of inflation in emerging markets. Median inflation more than doubles (from less than seven percent to 16 percent) as debt rises frm the low (0 to 30 percent) range to above 90 percent. Fiscal dominance is a plausible interpretation of this pattern.”

The reading of the Phillips circuits of the 1970s by Cochrane (2011Jan, 25) is doubtful about the output gap and inflation expectations:

“So, inflation is caused by ‘tightness’ and deflation by ‘slack’ in the economy. This is not just a cause and forecasting variable, it is the cause, because given ‘slack’ we apparently do not have to worry about inflation from other sources, notwithstanding the weak correlation of [Phillips circuits]. These statements [by the Fed] do mention ‘stable inflation expectations. How does the Fed know expectations are ‘stable’ and would not come unglued once people look at deficit numbers? As I read Fed statements, almost all confidence in ‘stable’ or ‘anchored’ expectations comes from the fact that we have experienced a long period of low inflation (adaptive expectations). All these analyses ignore the stagflation experience in the 1970s, in which inflation was high even with ‘slack’ markets and little ‘demand, and ‘expectations’ moved quickly. They ignore the experience of hyperinflations and currency collapses, which happen in economies well below potential.”

Yellen (2014Aug22) states that “Historically, slack has accounted for only a small portion of the fluctuations in inflation. Indeed, unusual aspects of the current recovery may have shifted the lead-lag relationship between a tightening labor market and rising inflation pressures in either direction.”

Chart VI-1B provides the tortuous Phillips Circuit of Brazil from 1963 to 1987. There were no reliable consumer price index and unemployment data in Brazil for that period. Chart VI-1B used the more reliable indicator of inflation, the wholesale price index, and idle capacity of manufacturing as a proxy of unemployment in large urban centers.

I D Current US Inflation. Unconventional monetary policy of zero interest rates and large-scale purchases of long-term securities for the balance sheet of the central bank is proposed to prevent deflation. The data of CPI inflation of all goods and CPI inflation excluding food and energy for the past six decades does not show even one negative change, as shown in Table CPIEX. There is acceleration in 2021 and 2022.

Chart I-12 provides the consumer price index NSA from 1913 to 2023. The dominating characteristic is the increase in slope during the Great Inflation from the middle of the 1960s through the 1970s. There is long-term inflation in the US and no evidence of deflation risks. There is increasing inflation in 2021-2023.

Chart I-13 provides 12-month percentage changes of the consumer price index from 1914 to 2023. The only episode of deflation after 1950 is in 2009, which is explained by the reversal of speculative commodity futures carry trades that were induced by interest rates driven to zero in a shock of monetary policy in 2008. The only persistent case of deflation is from 1930 to 1933, which has little if any relevance to the contemporary United States economy. There are actually three waves of inflation in the second half of the 1960s, in the mid-1970s and again in the late 1970s. Inflation rates then stabilized in a range with only two episodes above 5 percent. There are current higher rates of inflation.

Table I-2 provides annual percentage changes of United States consumer price inflation from 1914 to 2022. There have been only cases of annual declines of the CPI after wars:

• World War I minus 10.5 percent in 1921 and minus 6.1 percent in 1922 following cumulative increases of 83.5 percent in four years from 1917 to 1920 at the average of 16.4 percent per year
• World War II: minus 1.2 percent in 1949 following cumulative 33.9 percent in three years from 1946 to 1948 at average 10.2 percent per year
• Minus 0.4 percent in 1955 two years after the end of the Korean War
• Minus 0.4 percent in 2009.

The decline of 0.4 percent in 2009 followed increase of 3.8 percent in 2008 and is explained by the reversal of speculative carry trades into commodity futures that were created in 2008 as monetary policy rates were driven to zero. The reversal occurred after misleading statement on toxic assets in banks in the proposal for TARP (Cochrane and Zingales 2009). There were declines of 1.7 percent in both 1927 and 1928 during the episode of revival of rules of the gold standard. The only persistent deflationary period since 1914 was during the Great Depression in the years from 1930 to 1933 and again in 1938-1939. Consumer prices increased only 0.1 percent in 2015 because of the collapse of commodity prices from artificially high levels induced by zero interest rates. Consumer prices increased 1.3 percent in 2016, increasing at 2.1 percent in 2017. Consumer prices increased 2.4 percent in 2018, increasing at 1.8 percent in 2019. Consumer prices increased 1.2 percent in 2020. Consumer prices increased 4.7 percent in 2021 during fiscal, monetary, and external imbalances. Consumer prices increased 8.0 percent in 2022 in a combination of energy policies with fiscal and monetary imbalance. Fear of deflation based on that experience does not justify unconventional monetary policy of zero interest rates that has failed to stop deflation in Japan. Financial repression causes far more adverse effects on allocation of resources by distorting the calculus of risk/returns than alleged employment-creating effects or there would not be current recovery without jobs and hiring after zero interest rates since Dec 2008 and intended forever in a self-imposed forecast growth and employment mandate of monetary policy. Unconventional monetary policy drives wide swings in allocations of positions into risk financial assets that generate instability instead of intended pursuit of prosperity without inflation. There is insufficient knowledge and imperfect tools to maintain the gap of actual relative to potential output constantly at zero while restraining inflation in an open interval of (1.99, 2.0). Symmetric targets appear to have been abandoned in favor of a self-imposed single jobs mandate of easing monetary policy even with the economy growing at or close to potential output that is actually a target of growth forecast. The impact on the overall economy and the financial system of errors of policy are magnified by large-scale policy doses of trillions of dollars of quantitative easing and zero interest rates. The US economy has been experiencing financial repression as a result of negative real rates of interest during nearly a decade and programmed in monetary policy statements until 2015 or, for practical purposes, forever. The essential calculus of risk/return in capital budgeting and financial allocations has been distorted. If economic perspectives are doomed until 2015 such as to warrant zero interest rates and open-ended bond-buying by “printing” digital bank reserves (http://cmpassocregulationblog.blogspot.com/2010/12/is-fed-printing-money-what-are.html; see Shultz et al 2012), rational investors and consumers will not invest and consume until just before interest rates are likely to increase. Monetary policy statements on intentions of zero interest rates for another three years or recently virtually forever discourage investment and consumption or aggregate demand that can increase economic growth and generate more hiring and opportunities to increase wages and salaries. The doom scenario used to justify monetary policy accentuates adverse expectations on discounted future cash flows of potential economic projects that can revive the economy and create jobs. If it were possible to project the future with the central tendency of the monetary policy scenario and monetary policy tools do exist to reverse this adversity, why the tools have not worked before and even prevented the financial crisis? If there is such thing as “monetary policy science”, why it has such poor record and current inability to reverse production and employment adversity? There is no excuse of arguing that additional fiscal measures are needed because they were deployed simultaneously with similar ineffectiveness. Jon Hilsenrath, writing on “New view into Fed’s response to crisis,” on Feb 21, 2014, published in the Wall Street Journal (http://online.wsj.com/news/articles/SB10001424052702303775504579396803024281322?mod=WSJ_hp_LEFTWhatsNewsCollection), analyzes 1865 pages of transcripts of eight formal and six emergency policy meetings at the Fed in 2008 (http://www.federalreserve.gov/monetarypolicy/fomchistorical2008.htm). If there were an infallible science of central banking, models and forecasts would provide accurate information to policymakers on the future course of the economy in advance. Such forewarning is essential to central bank science because of the long lag between the actual impulse of monetary policy and the actual full effects on income and prices many months and even years ahead (Romer and Romer 2004, Friedman 1961, 1953, Culbertson 1960, 1961, Batini and Nelson 2002). Jon Hilsenrath, writing on “New view into Fed’s response to crisis,” on Feb 21, 2014, published in the Wall Street Journal (http://online.wsj.com/news/articles/SB10001424052702303775504579396803024281322?mod=WSJ_hp_LEFTWhatsNewsCollection), analyzed 1865 pages of transcripts of eight formal and six emergency policy meetings at the Fed in 2008 (http://www.federalreserve.gov/monetarypolicy/fomchistorical2008.htm). Jon Hilsenrath demonstrates that Fed policymakers frequently did not understand the current state of the US economy in 2008 and much less the direction of income and prices. The conclusion of Friedman (1953) that monetary impulses increase financial and economic instability because of lags in anticipating needs of policy, taking policy decisions and effects of decisions. This a fortiori true when untested unconventional monetary policy in gargantuan doses shocks the economy and financial markets.

The consumer price index of housing is in Chart I-16. There was also acceleration during the Great Inflation of the 1970s. The index flattens after the global recession in IVQ2007 to IIQ2009. Housing prices collapsed under the weight of construction of several times more housing than needed. Surplus housing originated in subsidies and artificially low interest rates in the shock of unconventional monetary policy in 2003 to 2004 in fear of deflation.

ID Current US Inflation. Consumer price inflation has fluctuated in recent months. Table I-3 provides 12-month consumer price inflation in Jul 2023 and annual equivalent percentage changes for the months from May 2023 to Jul 2023 of the CPI, the core CPI and major segments. The final column provides inflation from Jun 2023 to Jul 2023. CPI inflation increased 3.2 percent in the 12 months ending in Jul 2023. The annual equivalent rate from May 2023 to Jul 2023 was 2.0 percent in the episode of shifting energy sources; and the monthly inflation rate of 0.2 percent annualizes at 2.4 percent. Prior inflation rates fluctuate in accordance with inducement of risk appetite or frustration by risk aversion of carry trades from zero interest rates to commodity futures. At the margin, the decline in commodity prices in sharp recent risk aversion in commodities markets caused lower inflation worldwide (with return in some countries in Dec 2012 and Jan-Feb 2013) that followed a jump in Aug-Sep 2012 because of the relaxed risk aversion resulting from the bond-buying program of the European Central Bank or Outright Monetary Transactions (OMT) (https://www.ecb.europa.eu/press/pr/date/2012/html/pr120906_1.en.html). Carry trades moved away from commodities into stocks with resulting weaker commodity prices and stronger equity valuations. There is reversal of exposures in commodities but with preferences of equities by investors. Geopolitical events in Eastern Europe and the Middle East together with economic conditions worldwide are inducing risk concerns in commodities at the margin magnified by policies shifting energy sources. With zero or very low interest rates, commodity prices would increase again in an environment of risk appetite, as shown in past oscillating inflation. Excluding food and energy, core CPI inflation was 4.7 percent in the 12 months ending in Jul 2023, 3.2 percent in annual equivalent from May 2023 to Jul 2023 and 0.2 percent in Jul 2023, which annualizes at 2.4 percent. There is no deflation in the US economy that could justify further unconventional monetary policy open-ended or forever with very low interest rates and cessation of bond-buying by the central bank but with reinvestment of interest and principal, or QE→∞ even if the economy grows back to potential. The FOMC engaged in increases in the Fed balance sheet. Financial repression of very low interest rates constituted protracted distortion of resource allocation by clouding risk/return decisions, preventing the economy from expanding along its optimal growth path. On Aug 27, 2020, the Federal Open Market Committee changed its Longer-Run Goals and Monetary Policy Strategy, including the following (https://www.federalreserve.gov/monetarypolicy/review-of-monetary-policy-strategy-tools-and-communications-statement-on-longer-run-goals-monetary-policy-strategy.htm): “The Committee judges that longer-term inflation expectations that are well anchored at 2 percent foster price stability and moderate long-term interest rates and enhance the Committee's ability to promote maximum employment in the face of significant economic disturbances. In order to anchor longer-term inflation expectations at this level, the Committee seeks to achieve inflation that averages 2 percent over time, and therefore judges that, following periods when inflation has been running persistently below 2 percent, appropriate monetary policy will likely aim to achieve inflation moderately above 2 percent for some time.” The new policy can affect relative exchange rates depending on relative inflation rates and country risk issues. On Jul 26 , 2023, the FOMC increased interest rates with the following statement (https://www.federalreserve.gov/newsevents/pressreleases/monetary20230726a.htm): “The U.S. banking system is sound and resilient. Tighter credit conditions for households and businesses are likely to weigh on economic activity, hiring, and inflation. The extent of these effects remains uncertain. The Committee remains highly attentive to inflation risks. The Committee seeks to achieve maximum employment and inflation at the rate of 2 percent over the longer run. In support of these goals, the Committee decided to raise the target range for the federal funds rate to 5-1/4 to 5-1/2 percent. The Committee will continue to assess additional information and its implications for monetary policy. In determining the extent of additional policy firming that may be appropriate to return inflation to 2 percent over time, the Committee will take into account the cumulative tightening of monetary policy, the lags with which monetary policy affects economic activity and inflation, and economic and financial developments. In addition, the Committee will continue reducing its holdings of Treasury securities and agency debt and agency mortgage-backed securities, as described in its previously announced plans. The Committee is strongly committed to returning inflation to its 2 percent objective.” (emphasis added).

In his classic restatement of the Keynesian demand function in terms of “liquidity preference as behavior toward risk,” James Tobin (http://www.nobelprize.org/nobel_prizes/economic-sciences/laureates/1981/tobin-bio.html) identifies the risks of low interest rates in terms of portfolio allocation (Tobin 1958, 86):

“The assumption that investors expect on balance no change in the rate of interest has been adopted for the theoretical reasons explained in section 2.6 rather than for reasons of realism. Clearly investors do form expectations of changes in interest rates and differ from each other in their expectations. For the purposes of dynamic theory and of analysis of specific market situations, the theories of sections 2 and 3 are complementary rather than competitive. The formal apparatus of section 3 will serve just as well for a non-zero expected capital gain or loss as for a zero expected value of g. Stickiness of interest rate expectations would mean that the expected value of g is a function of the rate of interest r, going down when r goes down and rising when r goes up. In addition to the rotation of the opportunity locus due to a change in r itself, there would be a further rotation in the same direction due to the accompanying change in the expected capital gain or loss. At low interest rates expectation of capital loss may push the opportunity locus into the negative quadrant, so that the optimal position is clearly no consols, all cash. At the other extreme, expectation of capital gain at high interest rates would increase sharply the slope of the opportunity locus and the frequency of no cash, all consols positions, like that of Figure 3.3. The stickier the investor's expectations, the more sensitive his demand for cash will be to changes in the rate of interest (emphasis added).”

Tobin (1969) provides more elegant, complete analysis of portfolio allocation in a general equilibrium model. The major point is equally clear in a portfolio consisting of only cash balances and a perpetuity or consol. Let g be the capital gain, r the rate of interest on the consol and r^e the expected rate of interest. The rates are expressed as proportions. The price of the consol is the inverse of the interest rate, (1+r^e). Thus, g = [(r/r^e) – 1]. The critical analysis of Tobin is that at extremely low interest rates there is only expectation of interest rate increases, that is, dr^e>0, such that there is expectation of capital losses on the consol, dg<0. Investors move into positions combining only cash and no consols. Valuations of risk financial assets would collapse in reversal of long positions in carry trades with short exposures in a flight to cash. There is no exit from a central bank created liquidity trap without risks of financial crash and another global recession. The net worth of the economy depends on interest rates. In theory, “income is generally defined as the amount a consumer unit could consume (or believe that it could) while maintaining its wealth intact” (Friedman 1957, 10). Income, Y, is a flow that is obtained by applying a rate of return, r, to a stock of wealth, W, or Y = rW (Friedman 1957). According to a subsequent statement: “The basic idea is simply that individuals live for many years and that therefore the appropriate constraint for consumption is the long-run expected yield from wealth r*W. This yield was named permanent income: Y* = r*W” (Darby 1974, 229), where * denotes permanent. The simplified relation of income and wealth can be restated as:

W = Y/r (1)

Equation (1) shows that as r goes to zero, r→0, W grows without bound, W→∞. Unconventional monetary policy lowers interest rates to increase the present value of cash flows derived from projects of firms, creating the impression of long-term increase in net worth. An attempt to reverse unconventional monetary policy necessarily causes increases in interest rates, creating the opposite perception of declining net worth. As r→∞, W = Y/r →0. There is no exit from unconventional monetary policy without increasing interest rates with resulting pain of financial crisis and adverse effects on production, investment and employment.

Chart I-18 provides the US consumer price index for housing from 2001 to 2023. Housing prices rose sharply during the decade until the bump of the global recession and increased again in 2011-2012 with some stabilization in 2013. There is renewed increase in 2014 followed by stabilization and renewed increase in 2015-2023. The CPI excluding housing would likely show much higher inflation. The commodity carry trades resulting from unconventional monetary policy have compressed income remaining after paying for indispensable shelter.

Chart I-19 provides 12-month percentage changes of the housing CPI. Percentage changes collapsed during the global recession but have been rising into positive territory in 2011 and 2012-2013 but with the rate declining and then increasing into 2014. There is decrease into 2015 followed by stability and marginal increase in 2016-2019 followed by initial decline in the global recession, with output in the US reaching a high in Feb 2020 (https://www.nber.org/research/data/us-business-cycle-expansions-and-contractions), in the lockdown of economic activity in the COVID-19 event and the through in Apr 2020 (https://www.nber.org/news/business-cycle-dating-committee-announcement-july-19-2021) with sharp recovery.

There have been waves of consumer price inflation in the US in 2011 and into 2023 (https://cmpassocregulationblog.blogspot.com/2022/03/accelerating-inflation-throughout-world.html and earlier https://cmpassocregulationblog.blogspot.com/2022/02/us-gdp-growing-at-saar-of-70-percent-in.html) that are illustrated in Table I-5. The first wave occurred in Jan-Apr 2011 and was caused by the carry trade of commodity prices induced by unconventional monetary policy of zero interest rates. Cheap money at zero opportunity cost in environment of risk appetite was channeled into financial risk assets, causing increases in commodity prices. The annual equivalent rate of increase of the all-items CPI in Jan-Apr 2011 was 4.9 percent and the CPI excluding food and energy increased at annual equivalent rate of 1.8 percent. The second wave occurred during the collapse of the carry trade from zero interest rates to exposures in commodity futures because of risk aversion in financial markets created by the sovereign debt crisis in Europe. The annual equivalent rate of increase of the all-items CPI dropped to 1.8 percent in May-Jun 2011 while the annual equivalent rate of the CPI excluding food and energy increased at 2.4 percent. In the third wave in Jul-Sep 2011, annual equivalent CPI inflation rose to 3.2 percent while the core CPI increased at 2.4 percent. The fourth wave occurred in the form of increase of the CPI all-items annual equivalent rate to 1.8 percent in Oct-Nov 2011 with the annual equivalent rate of the CPI excluding food and energy remaining at 2.4 percent. The fifth wave occurred in Dec 2011 to Jan 2012 with annual equivalent headline inflation of 1.8 percent and core inflation of 2.4 percent. In the sixth wave, headline CPI inflation increased at annual equivalent 2.4 percent in Feb-Apr 2012 and 2.0 percent for the core CPI. The seventh wave in May-Jul occurred with annual equivalent inflation of minus 1.2 percent for the headline CPI in May-Jul 2012 and 2.0 percent for the core CPI. The eighth wave is with annual equivalent inflation of 6.8 percent in Aug-Sep 2012 but 5.7 percent including Oct. In the ninth wave, annual equivalent inflation in Nov 2012 was minus 2.4 percent under the new shock of risk aversion and 0.0 percent in Dec 2012 with annual equivalent of 0.0 percent in Nov 2012-Jan 2013 and 2.0 percent for the core CPI. In the tenth wave, annual equivalent of the headline CPI was 6.2 percent in Feb 2013 and 1.2 percent for the core CPI. In the eleventh wave, annual equivalent was minus 3.0 percent in Mar-Apr 2013 and 0.6 percent for the core index.

In the twenty-first wave, headline consumer prices decreased at 1.2 percent in annual equivalent in Aug-Sep 2015 while core prices increased at annual equivalent 1.8 percent. In the twenty-second wave, consumer prices increased at annual equivalent 1.2 percent for the central index and 2.4 percent for the core in Oct-Nov 2015.

The conclusion is that inflation accelerates and decelerates in unpredictable fashion because of shocks or risk aversion and portfolio reallocations in carry trades from zero interest rates to commodity derivatives. There are recent increases in shifting sources of energy.

The behavior of the US consumer price index NSA from 2001 to 2023 is in Chart I-20. Inflation in the US is very dynamic without deflation risks that would justify symmetric inflation targets. The hump in 2008 originated in the carry trade from interest rates dropping to zero into commodity futures. There is no other explanation for the increase of the Cushing OK Crude Oil Future Contract 1 from $55.64/barrel on Jan 9, 2007 to $145.29/barrel on July 3, 2008 during deep global recession, collapsing under a panic of flight into government obligations and the US dollar to $37.51/barrel on Feb 13, 2009 and then rising by carry trades to $113.93/barrel on Apr 29, 2012, collapsing again and then recovering again to $105.23/barrel, all during mediocre economic recovery with peaks and troughs influenced by bouts of risk appetite and risk aversion (data from the US Energy Information Administration EIA, https://www.eia.gov/). The unwinding of the carry trade with the TARP announcement of toxic assets in banks channeled cheap money into government obligations (see Cochrane and Zingales 2009). There is sharp increase in 2021 and into 2022-2023.

Chart I-21 provides 12-month percentage changes of the consumer price index from 2001 to 2023. There was no deflation or threat of deflation from 2008 into 2009. Commodity prices collapsed during the panic of toxic assets in banks. When stress tests in 2009 revealed US bank balance sheets in much stronger position, cheap money at zero opportunity cost exited government obligations and flowed into carry trades of risk financial assets. Increases in commodity prices drove again the all-items CPI with interruptions during risk aversion originating in multiple fears but especially from the sovereign debt crisis of Europe. There are sharp increases in 2021-2023.

The trend of increase of the consumer price index excluding food and energy in Chart I-22 does not reveal any threat of deflation that would justify symmetric inflation targets. There are mild oscillations in a neat upward trend.
