Risky assets overall struggled to gain momentum after Monday's relief rally, with weak manufacturing surveys pointing to global economic headwinds. Against a basket of its rivals, the dollar was 0.1% lower at 96.70 and not far from a three-month low of 95.84 hit last week, as traders priced in aggressive interest rate cuts by the Federal Reserve of at least three times by the end of the year.
The euro got a brief boost after a media report said the European Central Bank was in no rush to cut interest rates at a July policy meeting. The single currency was last slightly up at $1.1289. Though central bank officials are divided on the timing of the next policy move, market gauges of interest rates have increased the odds of an ECB cut later this month, thanks to a global drop in bond yields. The Australian dollar was the sole spot of strength in the currency market, rising 0.4% to US$0.6995 after the RBA lowered interest rates by 25 basis points to a record low of 1.00%, matching economists' expectations.
