Abstract
Since 1997, the Bank of England Monetary Policy Committee (MPC) has met monthly to set the UK policy interest rate. Using a Markov-switching framework that incorporates endogenous transition probabilities, we examine intraday, five-minute return data for evidence of systematic patterns in exchange rate movements on MPC policy announcement days. We find evidence for non-linear regime switching between a high-volatility, informed trading state and a low-volatility, liquidity trading state. MPC surprise announcements are shown to significantly affect the probability that the market enters and remains within the informed trading regime, with some limited evidence of market positioning just prior to the announcement.
