Analyst: Google's favorable foreign exchange rate to hit bump

After 10 straight quarters of grabbing a favorable foreign-exchange rate, Google's luck is expected to hit a bump in the third quarter, according to a report Monday by a Wall Street analyst.

The search giant, which relies on more than half of its gross revenues coming from overseas operations, is expected to take a sequential $22 million hit to its third-quarter gross revenue, due to unfavorable exchange rates, according to a report by Collins Stewart analyst Sandeep Aggarwal.

As a result, Google's anticipated international gross revenue is expected to come in at $3.03 billion for the third quarter, verses $3.25 billion had the exchange rates stayed the same.

Over the past 10 quarters, Google has enjoyed a favorable exchange rate, as the local currency in many of the countries that it operates has shown strength against the dollar. But as the dollar has grown relatively stronger in the quarter, especially against the yen in Japan, Google has seen its favorable exchange rate evaporate.

Nonetheless, Aggarwal notes in his report:

Though Google will not have currency benefits in Q3 and U.S. growth is moderating, our view is that Google will be able to meet the Street's expectations due to the combination of healthy CPC (cost per click) improvement and international strength.

Google is expected to post worldwide gross revenue of nearly $5.77 billion in the third quarter, up from $4.83 billion a year ago and an increase from $5.37 billion in the previous quarter.

Google's third quarter ends September 30.
