Macro & Central BanksFalling PricesNegative Inflation
Deflation
A sustained fall in the general price level, which raises the real burden of debt and is difficult for central banks to reverse.
What Deflation means
Deflation is a sustained decline in the general price level, the mirror image of inflation. It is distinct from disinflation, which merely means inflation slowing while prices still rise. Deflation is treated as dangerous because it raises the real value of existing debts: borrowers must repay in money that buys more than the money they borrowed, which squeezes balance sheets and can force asset sales. It can also become self-reinforcing if households and firms delay purchases in the expectation that goods will be cheaper later, further weakening demand.
Central banks fight deflation aggressively, cutting rates toward the effective lower bound and turning to asset purchases and forward guidance when conventional easing is exhausted. That policy response is typically negative for the currency because it drives domestic yields toward or below those available elsewhere. The important caveat is that not all price falls are alarming: a decline caused by a genuine productivity improvement or a one-off energy collapse differs fundamentally from a broad demand-driven spiral, and central banks generally look through the former.
Worked example
If an economy reports year-on-year prices at minus 0.4 percent for several consecutive months, markets would expect a large easing package, and the currency would typically weaken against higher-yielding peers. Hypothetical illustration.
