NEW YORK, May 30 (Reuters) - The dollar eased against other major currencies on Friday as traders tidied up books at month’s end and warily awaited potentially market-moving meetings next week by the European Central Bank and other monetary policymakers.
The dollar, as tracked by the U.S. dollar index of a half dozen currency pairs, traded softer in a tight range and was last off 0.11 percent at 80.487. Earlier this week, the index was at highs not seen since early April.
The euro, which has lost 1.75 percent against the dollar during May, was also up on the day, 0.2 percent to $1.3627, after touching a daily low of $1.3599.
“There’s caution ahead of the event risk coming in the form of the central bank meetings. With May ending, that will likely make for low volatility today,” said Shaun Osborne, chief foreign exchange strategist at TD Securities in Toronto.
Attention in currency and other global markets is now firmly focused on next week’s European Central Bank meeting, which is expected to deliver more policy easing.
It comes as the conviction that the Bank of Japan would also take more action this summer has been shaken, underpinning a rise for the yen to almost four-month highs against the euro. The euro last stood at 138.57 yen, up 0.11 percent.
Likewise, while the dollar has gained this week, U.S. Treasury yields have fallen, and dealers said there was talk of some substantial fund option bets on the yen strengthening to as little as 98 per dollar over the next month.
On Friday, the dollar traded at 101.64 yen, down 0.13 percent for the day.
The euro has fallen almost 3 percent against the dollar in just the past three weeks, hammered by expectations that the ECB will deliver a substantial blow by pumping more cash into the euro zone economy and lower market interest rates.
That euro move has left the market looking divided, however, on whether the single currency can fall further, whatever the ECB does next week.
Policymakers at central banks in Australia, Canada and Britain also meet next week, and America’s sometimes market-rattling monthly employment data will be published on June 6.
The Australian dollar, this week’s biggest gainer among the major currency pairs, on Friday bumped up against resistance around $0.9320 and last traded off 0.12 percent at $0.9296. (Additional Reporting By Patrick Graham in London; Editing by Nick Zieminski)
