Foreign-exchange intervention
Intervention can change demand for currencies or signal policy intentions, but its effect depends on scale, credibility, market conditions and accompanying policies. Authorities may offset or leave the domestic monetary effects, depending on their approach. Buying domestic currency tends, other things equal, to support its price; it does not guarantee a particular exchange rate indefinitely. Distinguish an authority’s market transactions from a business’s hedge and from general fiscal or interest-rate policy. Institutional responsibilities and actual regimes depend on the jurisdiction.
Worked example
An authority sells foreign reserves and buys domestic currency in an attempt to support the domestic currency. Market expectations and the available reserves affect whether and for how long the intervention changes conditions.
Common mistake
Assuming intervention guarantees a sustained appreciation or confusing central-bank transactions with an exporter’s forward hedge.
