Explain the situation of 'Liquidity Trap'

A liquidity trap is a situation in monetary economics in which a country's nominal interest rate has been lowered nearly or equal to zero to avoid a recession, but the liquidity in the market created by these low interest rates does not stimulate the economy. In these situations, borrowers prefer to keep assets in short-term cash bank accounts rather than making long-term investments. This makes a recession even more severe, and can contribute to deflation.
