The IMF thought the euro-dollar exchange rate was “broadly in line with fundamentals” at the time the fund prepared the regional economic outlooks released this week, Bakker said today in Belgrade, Serbia’s capital.

“Since then, we have seen further appreciation of the euro and it’s probably close to overvaluation,” he said. “If there would be further sharp appreciation this would probably affect growth in Western Europe, in eastern Europe, in emerging Europe.”

In case of a revised economic outlook, the IMF would consider the “much higher” exchange rate, he said.

The euro has gained 6.8 percent against the dollar over the past month, the biggest gain among 16 major currencies tracked by Bloomberg. The single currency rose 0.4 percent to $1.4026 as of 1:44 p.m. in Belgrade.
