The Determinants of Foreign Exchange Intervention by Central Banks: Evidence from Australia.

Intervention by the Reserve Bank of Australia on foreign exchange markets from 1993 to 1997 is conjectured to have been determined by exchange rate trend correction, exchange rate volatility smoothing and profitability considerations. Using Probit and friction models, we show that these factors were significant influences on intervention behaviour Consistent with the constraint of intervening only when a clear trend is apparent, we find that above average measures of deviations from trend and of volatility muted the response of the Reserve Bank.
