Disinflation Phase

A disinflation is a period during which the rate of inflation falls—prices still rise, but at a slower pace. It is distinct from deflation, where the absolute price level falls. A typical disinflation occurs when central bank policy tightens or when commodity and labor cost pressures ease.

How disinflation unfolds

In the years after 2020, the US experienced rapid inflation—rising from 1% in 2021 to 9% in mid-2022 due to supply chain disruptions, fiscal stimulus, and accommodative monetary policy. The Fed responded by raising interest rates sharply from near-zero to over 5% in 18 months.

As rates rose, growth slowed, employment stayed resilient, and commodity prices retreated from spikes. Wage growth, which had accelerated, began to moderate. By late 2023, consumer price inflation had fallen toward 3–4%, still above the Fed’s 2% target but trending downward. This is disinflation: prices are rising, but the pace of rise is decelerating.

Disinflation vs. deflation vs. inflation

• Inflation: Prices rising at an accelerating pace (e.g., 5% → 8% → 10%). Usually undesired.
• Disinflation: Prices rising at a decelerating pace (e.g., 8% → 6% → 4% → 2%). Often desirable; signals Fed success.
• Deflation: Absolute price level falling (e.g., −2% year-over-year). Rare and usually bad; promotes debt burden, defers consumption.

Most developed economies spend most of their time in disinflation or low-inflation environments. Deflation is a crisis event (2008–2009, Japan 1990s–2000s). Surging inflation is also relatively rare since the 1980s Volcker tightening.

Why disinflation matters for investing

Bonds outperform: In disinflation, yields tend to fall as central bank confidence grows and inflation expectations recede. A bond with 4% coupon becomes more valuable (in mark-to-market terms) as new bonds are issued with 2% coupons. Bond investors capture both coupon returns and price appreciation—the “double whammy” of disinflation.

Growth stocks rally: Falling interest rates reduce the discount rate used in discounted cash flow models, supporting growth stocks and tech. A software company with high future cash flows becomes more valuable when those cash flows are discounted at 2% instead of 5%.

Cyclicals and commodities lag: Cyclical industries (industrials, energy) depend on economic growth and inflation. If disinflation is driven by slowing demand, cyclicals underperform. If disinflation is driven by falling commodity costs (e.g., oil from $120 to $60), energy stocks suffer especially.

Volatility often spikes initially: The transition from inflation to disinflation is not smooth. If inflation remains “hot” longer than the Fed expected, or if growth slows faster than expected, equity and credit volatility can surge. Only as disinflation is confirmed (via falling CPI, PCE, and wage growth data) do markets stabilize.

Policy implications

Central banks generally welcome disinflation from elevated levels. The Federal Reserve targets 2% inflation; disinflation from 8% to 3% is progress. However, they must balance two risks:

1. Overshooting into deflation: If the Fed tightens too much and demand collapses, deflation can result—bad for debtors, economically damaging.
2. De-anchoring expectations: If disinflation is too slow, inflation expectations can become unanchored; wage bargainers and businesses expect ongoing high inflation and price accordingly, reigniting wage-price spirals.

The “soft landing” scenario—disinflation without recession—is the ideal outcome. Growth remains resilient, unemployment stays low, and inflation gradually reaches target. Hard landings see disinflation accompanied by job losses and recession.

Historical examples

1984–1986 (US): The Federal Reserve under Paul Volcker broke stagflation with aggressive rate hikes. Inflation fell from 13% (1980) to below 3% by 1986. The transition was severe—unemployment hit 10% in 1982—but disinflation succeeded, launching a bull market in bonds and equities.

1993–1998 (US): The Fed’s rate tightening in 1994–1995 induced a brief disinflation from 3% to 1.5%. Growth remained strong, unemployment fell, and bond yields plummeted—the classic goldilocks scenario.

2022–2024 (US): The Fed raised rates from near-zero to 5%+, and inflation retreated from 9% toward 3%. Energy stocks and cyclicals underperformed; bonds and tech rebounded sharply.

Challenges in measurement

Disinflation can be obscured by composition shifts. The Fed tracks core inflation (excluding food and energy) because those categories are volatile. During a disinflation, commodity-heavy sectors may still see price acceleration while services inflation falls, creating mixed signals.

The Fed also monitors inflation expectations via surveys and break-even inflation rates (yield difference between Treasuries and TIPS). If expectations drift lower too quickly during disinflation, the Fed may pause or reverse tightening to avoid deflation.
