Ospraie Management's flagship fund lost 38.6% — biggest commodity fund collapse of 2008

Ospraie Management was one of the world's largest commodity-focused hedge funds, founded by Dwight Anderson in 1999. By 2008, the firm managed nearly $9 billion in assets, with its flagship Ospraie Fund investing across energy, mining, and resource equities. Anderson had previously bought back Lehman Brothers' 20% stake in the firm, maintaining independence.

In September 2008, Ospraie closed its flagship fund after the fund lost 38.6% of its value during the year. The losses were driven by falling commodity prices, as the global financial crisis triggered a sharp decline in energy, metals, and mining stocks. The fund had been heavily concentrated in commodity-related positions, and the sudden reversal of the commodities super-cycle caught it fully exposed.

The closure was one of the largest hedge fund collapses of 2008. Investors in the flagship fund lost more than a third of their capital. Ospraie Management continued operating as a firm, launching new funds in 2009 and diversifying into private equity and venture capital, but the flagship fund's collapse marked the end of its era as a dominant commodity hedge fund.

The case illustrated the danger of concentration risk in commodity investing. A fund that bets heavily on a single sector can be destroyed when that sector turns, even if the underlying thesis was correct for years. Ospraie's collapse was a reminder that even the best commodity traders cannot escape the macro forces that move entire markets.
