Deutsche Bank’s former top global arbitrage trader will open his own hedge fund firm next month with more than $1 billion, the largest hedge fund launch of the year so far.

Roc Capital Management has raised $1.2 billion, Bloomberg News reports. Nearly half of the money—$500 million—comes from Deutsche Bank, Roc founder Arvind Raghunathan’s former employer, and will be managed in a separate account.

Raghunathan served as head of Deutsche Bank’s global arbitrage group, leading its Equitech Group quantitative trading team. The German bank shed the 20-strong team earlier this year as part of its cutback on proprietary trading. Equitech lost 1% last year.

In addition to the 20 Equitech team members, New York-based Roc will also have a 40-member team in India.

Roc’s launch is more than twice the size of the second-largest planned hedge fund debut this year. Tyrus Capital, led by former Deephaven Capital Management fund manager Tony Chedraoui, will open its doors in October, and has raised more than $500 million.
