What is a Liquidity Trap?
A liquidity trap is an economic situation in which interest rates are very low, but monetary policy becomes ineffective because people and institutions prefer holding cash rather than spending or investing it.
Definition
Liquidity Trap refers to a condition where increases in the money supply fail to stimulate economic activity because liquidity is hoarded, limiting the effectiveness of conventional monetary policy tools.
Key Takeaways
- Occurs when interest rates are near zero and monetary policy loses effectiveness.
- Characterised by high demand for cash and low willingness to spend or invest.
- Often associated with deflationary pressures and weak economic growth.
- Requires unconventional policy responses to restore demand.
Understanding a Liquidity Trap
A liquidity trap typically arises during severe economic downturns or prolonged periods of deflationary pressure. Even when central banks lower interest rates or inject liquidity into the economy, households and businesses may remain cautious, choosing to save rather than spend.
In this environment, borrowing costs are already low, so additional monetary easing does not significantly increase lending or investment. As a result, traditional policy tools such as interest rate cuts lose their ability to stimulate demand.
Liquidity traps are especially challenging because expectations of weak growth or falling prices reinforce the preference for holding cash, prolonging economic stagnation.
Importance in Business or Economics
- Explains limits of conventional monetary policy during deep downturns.
- Influences the use of unconventional tools such as quantitative easing.

Types or Variations
