The euro slipped against the dollar and yen on Tuesday, undermined by German sentiment data that was slightly below expectations and comments from European Central Bank officials saying they were prepared to do more to support the region's fragile recovery.
The data on Europe's biggest economy came a day after ECB President Mario Draghi said the bank was ready to provide more long-term loans to keep money-market rates from rising. Data from the Ifo think tank on Tuesday showed that German business morale improved slightly in September to touch a 17-month high, but the index fell short of the consensus forecast.
The euro was flat under $1.35. Support was cited at the August high of $1.3453. Large options expiries were reported at $1.3500 and $1.3200.
