During the European exchange market turmoil
in 1992-93 it was evident that speculative attacks tended to spread across
currencies. Using a twocountry version of the model developed by Flood and
Garber (1984) we show how a speculative attack against one currency may
accelerate the "warranted" collapse of a second parity. More
importantly, even if the parity of the second currency is viable in the absence
of a collapse of the first one, it might be subjected to a speculative attack if
the reserves available to defend the parity are "small".
