The euro dropped for a third day against the dollar as companies from Goldman Sachs Group Inc. to Royal Bank of Scotland Group Plc predicted the European Central Bank will cut interest rates next month.

The shared currency weakened versus all except two of its 16 major counterparts after ECB President Mario Draghi said yesterday that policy makers would be “comfortable” with taking action in June. Norway’s krone strengthened for a fourth day against the euro as a measure of underlying inflation surpassed economists’ forecasts. The yen headed for a weekly gain as a decline in Treasury yields reduced demand for dollars among Japanese investors.

“It’s not often the European Central Bank precommits to a rate cut or a change in policy at an upcoming meeting,” said Paul Robson, a senior foreign-exchange strategist at RBS in London. “It was quite aggressive talk. It’s pretty clear what the market made of it. It’s not much of a surprise to see the euro heading lower.”

The euro fell 0.2 percent to $1.3812 at 6:14 a.m. in New York, extending this week’s loss to 0.4 percent. It climbed to $1.3993 yesterday, the strongest since October 2011. The shared currency dropped 0.1 percent to 140.54 yen. The yen was little changed at 101.75 per dollar, having appreciated 0.4 percent this week.
