Concerted Intervention

The simultaneous buying or selling of a currency in foreign exchange markets by several central banks. Concerted intervention is usually undertaken in support of a central bank which is trying to maintain a particular exchange rate for its currency or is trying to slow the rate at which it is rising or falling. The intervention may be designed to strengthen or weaken a currency as a matter of deliberate policy, or to fight off speculative currency flows.
