Wosh is not likely to be Volker II.

The current U.S. Consumer Price Index (CPI) trend shows similarities to certain patterns of the 1970s, but macroeconomic fundamentals, debt levels, and policy tools have undergone fundamental changes. In April 2026, the U.S. CPI increased by 3.8 year-over-year, a significant rebound from 3.3% in March, with energy prices contributing notably, including a 28.4% year-over-year increase in gasoline prices. This upward trend has sparked market concerns about persistent inflation, especially in the context of Federal Reserve Chairman Kevin Warsh taking office in May 2026.

Historical Comparison of Inflation Paths

Inflation in the 1970s in the U.S. exhibited significant volatility. Starting in the mid-1960s, inflation rose modestly, then accelerated around 1972 due to factors like the departure from the gold standard, reaching nearly 12%. It then briefly declined, bottomed out around 1977, and surged again, exceeding 14% in 1980. This cycle was driven by multiple factors including the oil crisis, fiscal expansion, and accommodative monetary policy. The Fed ultimately responded with sharp rate hikes under Paul Volcker, with the federal funds rate approaching 20%, successfully suppressing inflation but also triggering a severe recession.

Comparing to the current cycle, since 2014, inflation has shown a similar pattern of “moderate rise—reversal—acceleration—reversal—rebound.” During 2020-2022, pandemic stimulus caused inflation to spike rapidly to around 9%, then receded during the rate hike cycle. A rebound re-emerged in 2025-2026, reaching 3.8% in April 2026. However, the Y-axis scales differ: the peak in the 1970s was near 12-14%, while the current peak is about 9%. If the pattern continues, the potential future peak could be in the 10-11% range, rather than the extreme levels of the 1970s.

It is important to note that CPI measurement methods have evolved. Today’s CPI incorporates more weights for housing and adjustments for substitution effects, which may lead to official data underestimating the true cost-of-living pressures. Shadow inflation indicators or alternative measures sometimes show higher readings, closer to those of the 1970s. Nonetheless, structural differences are significant: globalization of supply chains, energy transitions, and technological advances (such as AI) provide potential disinflationary forces, whereas the 1970s environment was dominated by supply shocks.

Debt Burden and Policy Space Constraints

The core tool used to combat inflation in the 1970s was aggressive rate hikes. At that time, U.S. debt-to-GDP was about 30%, with federal revenues stable around 17-18%. Even if 10-year Treasury yields rose to about 15%, the government still had fiscal space to bear higher interest costs. Although the Volcker rate hike cycle was painful, it did not trigger a sovereign debt sustainability crisis.

The current situation is markedly different. By 2026, U.S. public debt-to-GDP is approximately 100-101%, with total debt approaching or exceeding 120%. Federal revenues as a share of GDP have remained stable around 17% (about 17.0% in 2025), with no significant breakthroughs despite tax reforms. This “Laffer curve” phenomenon indicates that excessive taxation can suppress growth and reduce revenue share.

Interest payments have become a heavy burden. Currently, 10-year Treasury yields hover around 4.5-4.6%, with annual net interest payments exceeding $1 trillion. If yields are forced higher to historical levels, the snowball effect on interest costs will further widen deficits, creating a vicious cycle. In 2026, the Fed’s federal funds rate remains high, and although Chairman Warsh emphasizes balance, he faces dual pressures: managing potential inflation rebound and considering the sensitivity of high debt levels to rate hikes.

This situation points to sovereign debt risks. Strictly replicating the rate hike path of the 1970s could trigger soaring debt costs, increased refinancing pressures, and even liquidity crises. Historical experience shows that high-debt countries under inflationary pressure often turn to financial repression strategies rather than pure monetary tightening.

Lessons from History: Yield Curve Control in the 1940s

After World War II, U.S. debt-to-GDP again exceeded 100%. To manage this debt, the Fed implemented Yield Curve Control (YCC), fixing short-term interest rates and capping long-term Treasury yields, while benefiting from post-war productivity recovery and fiscal tightening, achieving smooth deleveraging. This policy prevented bond market yield runaway and provided a low-cost financing environment for economic growth.

Today, the “dividends” of the 1940s are absent: no large-scale post-war spending cuts, social welfare programs like Medicare and Social Security account for a high share of the budget, making strict fiscal tightening difficult. Although productivity growth has potential through AI and other innovations, short-term structural deficits are unlikely to be fully offset. Therefore, YCC or similar financial repression measures might be options, but they would require the Fed to expand its balance sheet to purchase government bonds and suppress yields.

However, Warsh has repeatedly expressed a desire to actively reduce the Fed’s balance sheet, which conflicts with the large-scale bond purchases needed for YCC. Persisting with balance sheet reduction would limit traditional monetary policy tools.

2020 Playbook Revisited: The Role of Banks

During the 2020 pandemic, the Fed temporarily suspended the Supplementary Leverage Ratio (SLR) rule, allowing banks to hold more Treasuries and expand credit. This measure effectively lowered Treasury yields (the 10-year yield briefly dropped to around 0.5%) and stimulated private sector financing. If such regulatory relaxations are made permanent or expanded, banks could act as “shadow QE”: absorbing government bond supply without expanding the Fed’s balance sheet, stabilizing yields, and supporting credit extension to the real economy.

This approach’s advantage is enabling “low interest rates + credit expansion,” easing government financing pressures, refinancing mortgages and corporate debt, improving household and corporate cash flows, and potentially stimulating consumption and investment. Coupled with productivity gains from AI, it could form a scenario of moderate growth and inflation easing.

However, risks are also significant. Credit expansion-driven booms often lead to asset bubbles, eventually ending in corrections—classic “boom-bust” cycles. Excessively loose financial conditions in history have amplified systemic risks, especially in high-debt environments.

Overall Assessment and Outlook

While U.S. inflation exhibits features similar to the 1970s, policy space is constrained by high debt levels. Pure rate hikes are costly; a more likely approach involves a hybrid strategy: limited interest rate management, regulatory easing to support bank bond purchases, and supply-side improvements (such as energy production and technological progress) to anchor inflation expectations.

In the short term (2026-2028), if bank credit expansion materializes, asset prices may rise and economic growth could accelerate temporarily, benefiting equities and real estate. But in the medium term, debt sustainability remains a core challenge. Long-term, achieving a rebalancing will require fiscal discipline, productivity improvements, and possibly structural reforms.

Kevin Warsh faces complex tests: balancing independence, managing inflation rebound risks, and debt constraints. His policy mix will profoundly influence global financial markets. As the issuer of the world’s reserve currency, the management of inflation and debt in the U.S. will not only determine domestic economic trajectories but also shape the stability of the international monetary system. Investors should closely monitor FOMC decisions, debt ceiling developments, and banking credit data to assess risks under different scenarios.

Overall, history does not simply repeat, but it offers valuable lessons. In today’s environment of high debt and limited policy flexibility, addressing inflation will require going beyond traditional monetarist frameworks, integrating fiscal-monetary coordination. Success or failure will depend on precise policy execution and the ability to manage external shocks.
