Interest rate decisions represent the most direct tool central banks use to influence currencies. Higher rates typically attract foreign capital seeking better returns, strengthening the currency. Lower rates make a currency less attractive to investors, often causing depreciation. The Federal Reserve, European Central Bank, Bank of England, and Bank of Japan all move markets with their rate decisions.

But the decision itself often matters less than the guidance accompanying it. If a central bank raises rates but signals this is the last increase, the currency might actually weaken as traders price in future policy. Forward guidance, the communication about future policy intentions, sometimes impacts currencies more than actual policy changes. The best forex traders read central bank statements carefully, looking for subtle shifts in language that telegraph future actions.

Quantitative easing and tightening directly affect currency values through money supply changes. When central banks buy assets, they inject money into the economy, typically weakening the currency. When they sell assets or reduce purchases, they remove money from circulation, often strengthening the currency. The Fed's tapering discussions in 2013 created the "taper tantrum" that moved currencies globally.

Central bank interventions, though less common now, can create dramatic moves. When the Swiss National Bank abandoned its euro peg in 2015, the franc surged 30% in minutes. When Japan's Ministry of Finance intervenes to support the yen, markets move violently. These interventions are rare but devastating to traders caught on the wrong side.

Inflation targeting frameworks guide much of modern central banking. Most major central banks target around 2% inflation. When inflation runs too hot, they raise rates. When it's too low, they cut rates or implement stimulus. Traders who understand each central bank's inflation tolerance and reaction function can anticipate policy moves before they happen.

Employment mandates also drive central bank decisions, particularly for the Federal Reserve with its dual mandate of price stability and maximum employment. Strong employment data might prompt rate increases even if inflation is contained. Weak employment might delay rate increases despite rising inflation. Understanding each central bank's specific mandate helps predict their actions.

Communication strategies vary dramatically between central banks. The Fed releases detailed minutes and holds press conferences. The ECB provides extensive commentary. The Bank of Japan tends toward less transparency. Some central banks surprise markets intentionally, while others telegraph every move months in advance. Adapting your trading approach to each central bank's communication style is essential.

Divergence between central bank policies creates the strongest trending currency moves. When the Fed was raising rates while the ECB maintained negative rates, the dollar strengthened significantly against the euro. When policy converges, currencies tend to range. Leading forex traders build strategies around policy divergence rather than fighting it.
