This paper provides an overview of the deregulation and then examines the early effects of the foreign exchange market deregulation. In particular we study how the bid-ask spread and conditional volatility in the yen/dollar foreign exchange market changed around the time of the deregulation. Intra-day data are analyzed with the following results: (1) Holding constant the effects of volume and volatility, the deregulation was associated with a convergence of Japanese quoted spreads toward those of other banks. (2) Modeling the persistence in volatility reveals that deregulation lowered conditional volatility.
