HONG KONG - Morgan Stanley is cutting at least 50 investment banking jobs in the Asia-Pacific region due to a deals slump, two sources with knowledge of the matter said.

The layoffs affect around 13 percent of the Wall Street bank's Asia investment banking workforce of 400 in the region, according to one of the sources.

A Morgan Stanley spokesperson declined to comment.

Bloomberg reported the job cuts first on Wednesday.

In the Asia-Pacific region, merger and acquisition advisory fees for the bank in the first quarter dropped 41.5 percent to $30.4 million, its latest earnings report showed.
