Disinflation
Disinflation is a slowdown in the rate of inflation — prices are still rising, but at a slower pace than before — as distinct from deflation, in which the price level itself is actually falling, and the intended result of deliberate central bank monetary tightening.
The distinction between disinflation and deflation is critically important and frequently confused in financial media. Both terms describe a falling inflation rate, but deflation means the price level itself is declining (negative inflation), while disinflation means inflation is positive but shrinking. If inflation runs at 8% one year and 4% the next, that is disinflation. If prices actually fall in absolute terms, that is deflation.
Disinflation is the normal intended result of monetary tightening. When the Federal Reserve raises interest rates, it deliberately tries to cool demand-side price pressures by raising borrowing costs. A successful tightening cycle produces disinflation — inflation moves from an elevated level back toward target without triggering a severe recession or outright deflation. The challenge lies in calibrating the tightening precisely enough to slow inflation without overshooting into demand destruction and deflation.
The most celebrated US disinflation occurred between 1980 and 1983 under Fed Chair Paul Volcker. Inflation fell from above 14% to under 4% — a dramatic reduction in price pressures. It came at significant cost: unemployment exceeded 10%, and the economy endured back-to-back recessions. The episode established the Fed's credibility as an inflation fighter and anchored inflation expectations at low levels for the next four decades.
The post-COVID disinflation beginning in 2022-2023 followed a similar pattern, though the recession feared by many economists never fully materialized. Inflation fell from above 9% in mid-2022 to below 3% by 2024, driven by supply chain normalization, falling goods prices, and Fed rate hikes. The Fed attempted to achieve a 'soft landing' — disinflation without recession — and broadly succeeded, an unusual outcome by historical standards.
For investors, disinflation has historically been a favorable equity market backdrop. As inflation falls back toward normal levels, the uncertainty premium embedded in asset prices diminishes, price-to-earnings multiple expansion often occurs as discount rates fall, and consumer spending power recovers relative to the peak-inflation squeeze. Fixed income benefits most directly, as the prospect of rate cuts drives bond prices higher. The early stages of a recognized disinflation trend, before it is fully priced in, have historically been rewarding for long-duration assets.
