A currency's value against others is set by supply and demand, and demand comes from many sources: foreign buyers of a country's exports, investors seeking higher interest rates, and those looking for a safe place to park money in uncertain times.

Interest rate differences are often the most powerful short-term driver. When one central bank raises rates relative to others, holding its currency becomes more attractive, and the exchange rate tends to rise. Expectations about future policy can move currencies before any decision is taken.

Winners and losers

A stronger currency makes imports cheaper, which helps consumers and can ease inflation. But it makes exports more expensive abroad, squeezing manufacturers and tourism. Companies that earn revenue overseas see those earnings shrink when converted back home.

Whether a strong currency is good news depends on whether you are buying or selling.

For countries that borrow in foreign currencies, the dynamic can be more dangerous. A weakening home currency raises the cost of servicing those debts, which is why some central banks intervene in currency markets to smooth sharp moves.
