Other countries, it appears, havemore to lose from a weak dollar than the US does.Perhaps as a result, there was a day's pause in thetrade that has seen the dollar hit 14-month lows while oil,denominated in dollars, briefl y hit $80 a barrel before falling.Brazil's imposition of a 2 per cent tax on capital infl ows, toboth stocks and bonds, showed strong intent. This movebrought the real, which has risen 54.5per cent against thedollar since its nadir, down by 3.8 per cent.
