A series of imminent events seem likely to presage future developments on the currency market.

Prime Minister Junichiro Koizumi, who will have a summit Saturday with U.S. President George W. Bush at the Camp David, Md., retreat appears to be seeking U.S. understanding of his reform agenda.

The summit could provide Koizumi with opportunities to learn from the market-oriented policies that helped the U.S. bounce back from the savings and loan crisis of the 1980s.
