Central banks have an important influence on the foreign exchange market. The decisions regarding interest rates, policy statements, projections for inflation, and economic growth all influence the value of currencies relative to each other. In the Forex market, central bank policy is vital to understand as it is usually the basis for any currency movement.
Why Central Bank Policy Matters
Currencies trade in pairs, which makes them relative in value. A currency can appreciate due to its own performance or simply because the respective country’s central bank will be perceived as more aggressive compared to another.
If the Fed announces an intention to raise interest rates and the ECB remains accommodative in terms of monetary policy, the dollar has historically tended to appreciate against the euro. An increase in rates is likely to stimulate demand for financial instruments issued in a particular currency due to the higher yields.
Policy Divergence: A Key Driver of FX Trends
When central banks adopt divergent policies or indicate different forward paths, divergence happens and results in a discrepancy in interest rates, expectations, and flows of capital.
Three factors explain how policy divergence influences currency pairs:
- Interest rate discrepancies: capital usually flows into countries whose interest rates are high.
- Forward expectations: markets normally incorporate the effects of anticipated policies.
- Investor risk sentiment: global risk appetite may amplify or offset policy divergence impact.
Impact on Major Currency Pairs
The response of the major currency pairs to central banks’ policy changes varies.
- EUR/USD rate is very sensitive to the difference in the monetary policy stance of the Fed and ECB. If the Fed becomes more hawkish compared to the ECB, EUR/USD might fall. At the same time, the strong statement at the ECB press conference, the changing inflation expectations could cause a reversal move.
- USD/JPY tends to follow the difference between yield expectations and the monetary policy in Japan. Under the scenario where the Federal Reserve implements tight monetary policy while the BoJ holds onto its accommodative stance, USD/JPY might climb.
- GBP/USD rate is impacted both by Bank of England and Federal Reserve policy, while the UK economy fundamentals such as labor costs, the inflation rate, GDP figures should be considered.
- AUD/USD follows yield expectations as well as the market sentiment, and the demand for commodities.
- USD/CHF currency pair is affected by the difference in monetary policies and safe haven flows into the CHF asset class.
What Traders Should Watch
It is wrong to concentrate on just the outcome of the rate decision. It is more important to understand the context surrounding it. These factors may include expectations of the market prior to the announcement, forward guidance tone, new forecast for inflation/growth, and movement in yields.
Trading Around Central Bank Announcements
Interest rate changes by central banks can be sources of great volatility, widened spreads, and rapid directional movements. Traders with short holding periods might concentrate on the immediate response to the news, whereas those with medium-term horizons tend to wait for confirmation following the first period of volatility.
