How a peg is held

A currency peg is when a country fixes its currency's exchange rate to another currency, usually the US dollar or the euro. The central bank buys or sells its own currency, using its foreign currency reserves, to keep the rate where it wants it, and may move interest rates in step with the currency it is pegged to.

When a peg breaks

If the reserves run low or the cost of holding the peg gets too high, a central bank may let it go. In January 2015 the Swiss National Bank dropped its cap on the franc against the euro, and the franc jumped sharply within minutes.
