John Brady, co-head of MF Global Inc.'s Chicago office, was having a vodka cocktail at the Ritz- Carlton in Naples, Florida, overlooking the Gulf of Mexico, on the day his company reported its largest-ever quarterly loss.

"Wow, the sun just set," Brady said to his wife and two colleagues attending a conference with him, he recalled in an interview. "I hope it doesn't set on MF Global."

A week later, on Oct. 31, the firm led by former Goldman Sachs Group Inc. co-Chief Executive Officer Jon Corzine collapsed. Brady and 1,065 colleagues joined a wave of firings that has washed away more than 200,000 jobs in the global financial-services industry this year, eclipsing 174,000 in 2009, data compiled by Bloomberg show. BNP Paribas SA and UniCredit SpA announced cuts last week, and the carnage likely will worsen as Europe's sovereign-debt crisis roils markets.
