The euro rose to its highest level in three months against the U.S. dollar on Monday as the greenback remained on the back foot amid expectations for the Federal Reserve to cuts interest rates later this year.

The euro built on gains from last week, when it added 1.4%, and rose to 1.1387 overnight, its highest since March 22. It was trading at 1.1379 by 03:12 AM ET (07:12 GMT).

The U.S. dollar index versus a basket of six major currencies was a shade lower at 95.63, having plumbed an overnight low of 95.57 after the Fed last week laid the groundwork for a potential rate cut as early as next month.

That weighed on the dollar and in turn reinvigorated its counterparts such as the euro, which has had troubles of its own including Italy's debt problem and the possibility of the European Central Bank having to ease policy.

"It is true that the ECB may have to ease policy especially with the Fed having shifted to an easing bias," said Yukio Ishizuki, senior currency strategist at Daiwa Securities.

"But the ECB already employs a negative interest rate policy and does not have much further room to ease even if they wanted to, unlike the Fed. It is factors like these which have seemingly supported the euro."

The dollar edged up 0.14% to 107.44 yen after hitting a near six-month low of 107.04 on Friday.

The U.S. currency was pressured further against the yen, which often serves as a safe haven in times of political angst, as tensions grew between Iran and the United States.

But it is difficult to see the greenback fall beyond 105 yen as a sustained flight from dollar-assets was unlikely, said Koji Fukaya, director at FPG Securities in Tokyo.

"For example the S&P 500 reached a record high thanks to prospective rate cuts. Stronger investor risk appetite slows any flight-to-quality into the yen," Fukaya said.

In focus was whether Washington and Beijing can resolve their trade dispute at a summit in Japan this week of leaders from the Group of 20 leading world economies.

Both China and the United States should make compromises in trade talks, Chinese Vice Commerce Minister Wang Shouwen said on Monday.

The Australian dollar rose to more than two-week high of 0.6961 earlier after Reserve Bank of Australia Governor Philip Lowe said it would be legitimate to question the effectiveness of global monetary policy easing to boost economic growth.

The comments were perceived to be slightly less dovish as just last week Lowe said a recent cut in Australia interest rates to an all-time low of 1.25% would not be enough to revive economic growth.

The Aussie was already on a steady footing after rebounding from a five-month low of 0.6832 last week when the Fed's tilt towards monetary easing helped offset bearishness from the probability of policy easing in countries including Australia and New Zealand.

The New Zealand dollar was at two-week highs of 0.6605, although the Reserve Bank of New Zealand is expected to echo the dovish sentiments of other central banks when it holds a policy meeting on Wednesday.
