TOKYO (Reuters) – Nomura Holdings (NYSE:) Inc shares dropped more than 7% early on Thursday after it posted a sharp fall in its quarterly net profit as worries about a global banking crisis roiled markets and hit its investment banking business.

Nomura, Japan’s biggest brokerage and investment bank, saw its shares slump 7.6% by early morning after being untraded with a glut of sell orders earlier in the day.

On Wednesday, the company reported a 76% fall in its quarterly net profit, joining Wall Street investment banks in reporting a slump in dealmaking fees as global mergers and acquisitions activity shrank to the lowest level in more than a decade in the last quarter.
