Inflation Supercycle

On the afternoon of October 3rd, 2023 something unprecedented happened in the U.S. Treasury market. For the first time ever, bear steepening caused the 20-year U.S. Treasury yield and the 2-year U.S. Treasury yield to uninvert.

Bear steepening refers to a scenario in which long-duration bond yields rise faster than short-duration bond yields, as bond yields rise across the term structure. In all past instances, inverted yield curves have normalized due to bull steepening. The probability that bear steepening would cause an inverted yield curve to normalize is so low that, until now, most term structure models excluded the possibility of it ever happening. In this post, I'll explain why this anomalous event is a major stagflation warning.

The chart above shows that the 10-year Treasury yield has been rising much faster than the 3-month Treasury yield throughout 2023, narrowing the once-deep yield curve inversion.

Since a yield curve inversion indicates that a recession is coming, and bear steepening indicates that the market is pricing in higher inflation for the short term, and even more so, for the long term, then bear steepening during a yield curve inversion indicates that high inflation may persist even during the recessionary phase. High inflation during the recessionary period is what defines stagflation. Since very strong bear steepening is normalizing a deeply inverted yield curve, the combination of these events is a warning that severe stagflation is likely coming.

High inflation has caused Treasury yields to surge at an astronomical rate of change. Bond prices, which move in the opposite direction as yields, have sharply declined causing destabilizing losses. The effects of these massive bond losses are not even close to being fully realized by the broad economy.

Despite the extreme pace of monetary tightening, many central banks are still struggling to contain inflation. Inflationary fiscal spending and ballooning debt-to-GDP levels are confounding central bank monetary policy efforts. In Argentina, for example, inflation continues to spiral higher despite the central bank raising interest rates to 133%.

The chart above shows that the central bank of Argentina has hiked interest rates to 133%. Despite this extreme interest rate, the country's inflation rate continues to spiral higher. In an inflationary spiral, there is no upper limit to how high interest rates can go.

As the Federal Reserve tightens the supply of the U.S. dollar -- the predominant global reserve currency -- all other countries (with less demanded fiat currency) generally must tighten their monetary supply by a greater degree in order to contain inflation. If a country fails to maintain tighter monetary conditions than the Federal Reserve, then the supply of that country's (lesser demanded) fiat currency will grow against the supply of the (greater demanded, and scarcer) U.S. dollar, causing devaluation of the former against the latter. In effect, by controlling the global reserve currency, the Federal Reserve is able to export inflation to other countries. This phenomenon is explained by the Dollar Milkshake Theory.

The forex chart above shows USDJPY pushing up against 150 yen to the dollar. The longer the Bank of Japan continues to maintain significantly looser monetary conditions than the Fed, the longer the yen will continue to devalue against the U.S. dollar.

The meteoric rise in bond yields is particularly concerning because it has broken the long-term downtrend, signaling the start of a new supercycle. After hitting the zero lower bound in 2020, yields have rebounded and pierced through long-term resistance levels.

The chart above shows that the 10-year U.S. Treasury yield broke above long-term resistance, ending the period of declining interest rates that characterized the monetary easing supercycle.

We've entered into a new supercycle, one in which lower interest rates over time are a thing of the past. The new supercycle will be characterized by persistently high inflation. It will start off insidiously, with brief periods of disinflation, but over the long term it will accelerate higher and higher, ultimately causing today's fiat currencies to meet the same fate that every fiat currency in history has met: hyperinflation.
