Currency Insights
RateUSD does not publish market commentary or forecasts. What follows is durable background on the forces that move exchange rates.
Interest rates
When a central bank raises policy rates relative to others, assets denominated in that currency pay more, demand for the currency rises and it tends to appreciate. Markets price expected moves in advance, so the surprise relative to expectations matters more than the decision itself.
Inflation
Persistently higher inflation erodes purchasing power and, over long horizons, tends to weaken a currency. Over short horizons the effect can invert, because high inflation prints raise expectations of tighter policy.
Trade and current account
A country importing far more than it exports must sell its own currency to buy foreign goods. Sustained deficits put downward pressure on the currency unless offset by capital inflows.
Risk sentiment
The dollar, Swiss franc and Japanese yen typically strengthen during market stress as investors move to perceived safety. Commodity currencies such as AUD, NZD and ZAR usually weaken in the same conditions.
Commodity prices
Exporters of oil, metals and agricultural goods see their currencies track the prices of what they sell. Importers experience the mirror image.
Central-bank intervention
Some countries peg or manage their currency. In those cases the published rate reflects official policy rather than free-floating market supply and demand, and parallel-market rates may differ substantially.
