When financial markets tumble, central banks should keep interest rates on hold rather than cut them to stabilize markets

What's this about?

People disagree about whether banks should keep rates the same when money markets fall.

The best choice depends on why markets fall and whether the trouble can spread.

What supporters say

• Keeping rates the same may stop banks and traders from taking too many risks.
• Cutting rates may clash with the goal of keeping prices steady and the money’s value strong.
• Special help for one troubled market may work better than changing rates for everyone.

What critics say

• Past money crises often needed fast rate cuts to stop more harm.
• A surprise rate cut can lift markets fast and make loans less costly.
• Rate cuts can stop falling prices from hurting firms, banks, and people with loans.

The bottom line

There is no rule that always works when markets tumble.

We are not sure which choice wins, because each choice may help in one case and hurt in another.

The claim that central banks should hold interest rates steady when markets tumble has no universal answer. The right choice depends on whether the market decline is a contained disruption or a sign that tighter credit is threatening the wider economy.

The case for

Holding rates can protect longer-term financial stability. Cutting rates to support falling asset prices may reward excessive risk-taking, encourage borrowing and push investors to search for higher returns. Research finds that lower rates can make banks and investors more willing to accept risk, potentially building vulnerabilities that worsen a later downturn (see Figure 1). 1

A market decline alone does not prove that the economy needs easier monetary policy. If inflation remains high, rate cuts could loosen financial conditions too soon, weaken the currency and make it harder to restore price stability. In that situation, keeping rates unchanged may be the safer choice.

Central banks also have tools that are more narrowly aimed at market stress. If the problem is a shortage of liquidity or a malfunction in one market, emergency lending, guarantees, asset purchases or financial-regulation measures may help without changing borrowing costs across the entire economy. This separation allows interest rates to remain focused on inflation while assistance is directed at the part of the financial system that is under strain. 2

The case against

The strongest argument for cutting rates is that financial stress can spread into the real economy. Falling asset prices can weaken borrowers’ balance sheets, reduce lending and deepen a downturn. Lower rates can counter that “financial accelerator” by reducing financing costs and supporting asset prices.

There is stronger evidence that unexpected rate cuts can improve markets quickly than that holding rates would stabilize them. Studies find that surprise easing raises share prices and lowers some risk premiums, improving broader financial conditions through borrowing costs and investor expectations. Holding rates while credit conditions tighten could therefore intensify the immediate shock rather than contain it (see Figure 2). 46

History also provides reasons not to hold rates automatically. The Federal Reserve cut rates during the 2007–09 financial crisis and again during the March 2020 contraction, alongside emergency lending, asset purchases and other measures. Markets and financial conditions improved after those broad responses, although the evidence cannot show how much of the improvement came from rate cuts alone. These episodes support easing as one part of a crisis response, not as proof that cutting rates is always sufficient or preferable. 5

Rate cuts may also fail when the underlying problem is insolvency rather than liquidity. Evidence from the European Central Bank suggests that monetary policy can pass less effectively through banks during sovereign and financial stress when institutions lack sufficient capital. In such cases, rate cuts may need to be combined with bank resolution, recapitalization, fiscal support or other financial measures.

The bottom line

The evidence does not support the claim as a universal rule. It gives a somewhat stronger short-term basis for cutting rates when market stress is spreading into credit, demand and employment. But it also provides credible support for holding rates when inflation is persistent, the turmoil is localized or easier policy would fuel leverage and risky investment.

The overall evidence therefore favors a conditional approach, with moderate confidence rather than a firm general rule. Central banks should not cut rates merely to prop up falling asset prices. But they should not hold automatically when a market shock is becoming a broad economic contraction. The crucial question is whether the problem is temporary market illiquidity, failing credit transmission or deeper insolvency—and whether targeted tools can address it without sacrificing price stability.
