Zero Interest Rate Policy (ZIRP)

Trading Term

Zero Interest Rate Policy (ZIRP) is a monetary policy strategy in which a central bank sets nominal interest rates at or near zero percent in an effort to stimulate economic activity during periods of economic stagnation or deflation. This approach is designed to lower the cost of borrowing, encourage investment and consumption, and increase liquidity in the financial system. ZIRP gained prominence during the global financial crisis of 2008 and was implemented by central banks including the U.S. Federal Reserve and the Bank of Japan.

Under ZIRP, central banks typically maintain overnight lending rates at near-zero levels and may supplement this with forward guidance or asset purchase programs (quantitative easing). The intent is to encourage lending to households and businesses, foster asset price growth, and raise inflation expectations when the economy faces disinflation or contraction. The policy, however, raises concerns over financial repression, capital misallocation, and asset bubbles.

ZIRP has significant implications for savers, pension funds, and bank profitability. Low returns on safe assets may push investors toward riskier securities, such as equities or corporate bonds, in search of yield. The exit from ZIRP is often delicate; central banks must balance growth, inflation, and financial stability to avoid abrupt market reactions. ZIRP remains a controversial but powerful tool in modern central banking.
