An unconventional monetary policy where a central bank purchases government bonds and other financial assets to inject money into the economy, lower long-term interest rates, and stimulate growth.
What Is Quantitative Easing?
Quantitative easing (QE) is a tool used by Central Bank institutions when conventional Interest Rate cuts reach their lower bound (near zero). The central bank creates new money electronically and uses it to purchase government bonds and sometimes corporate bonds or other assets from the open market. This increases the Money Supply, pushes down long-term yields, and encourages lending and investment.
QE and Forex Markets
QE is generally bearish for the domestic currency because it expands the money supply and reduces yields. When the Federal Reserve launched QE programs (2008-2014, 2020-2022), USD weakened against most major currencies. Conversely, the Bank of Japan's massive QE program weakened JPY for years. If one central bank runs QE while another tightens, the divergence amplifies currency moves between their respective currencies.
Impact Mechanics
QE weakens currencies through three channels: lower yields reduce foreign capital inflows, expanded money supply dilutes purchasing power, and the signal of easy policy shifts expectations Dovishly. The size and pace of QE matter as much as its existence. A central bank announcing $120 billion per month in purchases creates more currency weakness than one purchasing $40 billion. The transition from QE to Tapering to Quantitative Tightening defines multi-year currency cycles.
