The Basics
- Simple definition: A situation where interest rates are near zero, and monetary policy becomes ineffective because people hoard money instead of spending or investing.
- Core idea: You can’t push on a string – lower rates don’t stimulate when rates are already near zero.
- Think of it as: Pushing harder on a brake pedal that’s already floored – nothing happens.
What It Actually Means
In a liquidity trap, people expect deflation or weak demand, so they hold cash even at zero interest rather than spend or invest. Monetary policy loses power because further rate cuts are impossible (can’t go below zero much), and increasing money supply just gets hoarded. Fiscal policy becomes the only tool. Keynes described this; Japan experienced it; many feared it after 2008.
Example
If Pakistan’s policy rate is already at 2% and a recession hits, cutting to 1% might not stimulate – banks still won’t lend due to risk, consumers still won’t borrow due to uncertainty. The economy is trapped.
Why It Matters (2026)
After years of near-zero rates globally, central banks worry about future traps. If another recession hits while rates are still low, they’ll have limited room. This justifies building “policy space” – raising rates now to have room to cut later.
