What Drives Currencies
A currency pair expresses the relative value of two economies. The dominant drivers are relative monetary policy, interest-rate differentials, inflation, growth and the capital flows that respond to all of these. Understanding which driver is in the ascendancy at any given time is the core of FX analysis.
Relative Monetary Policy & Interest-Rate Differentials
Currencies tend to be attracted to higher real yields. When one central bank is tightening while another is on hold or easing, the interest-rate differential widens and capital typically flows toward the higher-yielding currency. This is one of the most durable relationships in FX — but it is a tendency, not a law, and expectations matter as much as the levels themselves.
Inflation, Labour Markets & Growth
Central banks react to inflation and labour-market strength. Hot inflation pressures a central bank toward tighter policy; weak employment and soft growth permit easing. Reading the data trajectory — not just the latest print — is what informs a view on the policy path.
Central Banks & Forward Guidance
What a central bank says about the future path of rates often moves markets more than the current rate itself. Forward guidance, dot plots, speeches and minutes are all read for shifts in the expected path. The gap between market expectations and the central bank's own guidance is where much of the opportunity and risk lies.
Bond Yields & Economic Expectations
Government bond yields encode the market's expectation of the policy path and the economy. Rising nominal yields can reflect expected tightening or rising inflation; real yields strip out inflation and often give a cleaner read on the policy and growth backdrop for a currency.
Risk Sentiment & Cross-Asset Relationships
In risk-off conditions, safe-haven currencies tend to appreciate and risk-sensitive ones depreciate. Equity volatility, commodity prices and credit spreads all feed into the risk environment that frames FX. Cross-asset confirmation — checking whether bonds, equities and commodities tell a consistent story — is essential before committing to an FX view.
Technical Analysis & Risk Management
Technical analysis defines the levels, structure and momentum that determine where the risk/reward of acting on a fundamental view is favourable. Invalidation is defined where the thesis is wrong; position sizing follows from the distance to that level. Risk management — not the call — determines the outcome of a trade.
