Paulson Subprime Trade: The Greatest Trade Ever

Key Takeaways

• John Paulson shorted subprime mortgage bonds with credit default swaps and won big in 2007.
• His firm reportedly earned more than $15 billion in 2007, with Paulson personally paid about $3.7 billion.
• One Paulson credit fund returned roughly 590 percent net for the year.
• Goldman Sachs paid $550 million to settle SEC charges over a Paulson-linked CDO; Paulson was not charged.

Background

In the mid-2000s John Paulson ran Paulson & Co., a mid-sized hedge fund best known for merger arbitrage, not for big macro calls. He was not a household name, and his firm was a fraction of the size of the giants. That changed when he and his analyst Paolo Pellegrini studied the U.S. housing market and concluded that home prices and the subprime mortgage bonds tied to them were badly overvalued.

The instrument that made the trade possible was the credit default swap, or CDS. A CDS works like an insurance policy on a bond: the buyer pays a small recurring premium, and if the underlying debt defaults, the seller pays out. Crucially, you do not have to own the bond to buy protection on it. That let Paulson bet against subprime mortgage securities he would never hold, with a known, limited cost and an enormous potential payoff.

He focused on the riskiest slices of subprime residential mortgage-backed securities and on the ABX index, a basket that tracked baskets of subprime home loans. Buying CDS on these references was cheap because, in 2005 and 2006, almost no one expected widespread defaults. Paulson was paying pennies to bet that something the market called nearly impossible would happen.

To press the bet, Paulson launched two dedicated funds, the Paulson Credit Opportunities funds, in 2006. Raising money was hard. According to reporting drawn from Gregory Zuckerman's account of the trade, his first housing-focused fund pulled in only about $147 million, a modest sum, because investors thought betting against American housing was reckless. For more than a year the position bled premium and showed losses while home prices kept climbing.

What Happened

The trade was underwater through late 2006 and into early 2007, then it turned. As subprime borrowers began missing payments in rising numbers, the value of CDS protection on subprime bonds soared, and the ABX index fell sharply. Paulson's once-mocked positions started printing money. Three years later, one specific deal he was involved in, Goldman Sachs's Abacus 2007-AC1, became the center of a landmark SEC fraud case.

• 2006: Paulson launches two dedicated credit funds and builds CDS positions against subprime mortgage bonds and the ABX index.
• Early 2007: Subprime distress accelerates; the value of Paulson's short positions climbs as the housing market shows strain.
• April 26, 2007: Goldman Sachs closes Abacus 2007-AC1, a synthetic CDO whose reference portfolio Paulson helped select while shorting it.
• End of 2007: Paulson's Credit Opportunity fund returns about 590 percent net; Credit Opportunity II returns about 352 percent.
• 2007 full year: Paulson & Co. reportedly earns more than $15 billion gross; Paulson is named the top-paid hedge fund manager.
• April 16, 2010: The SEC files securities fraud charges against Goldman Sachs and employee Fabrice Tourre over Abacus 2007-AC1.
• July 15, 2010: Goldman settles for $550 million, then a record SEC penalty against a Wall Street firm.
• August 1, 2013: A federal jury finds Tourre liable on six counts; he is later ordered to pay about $825,000.

By the end of 2007 the numbers were staggering. Paulson's flagship Credit Opportunity fund returned roughly 590 percent net of fees, and its sister fund, Credit Opportunity II, returned about 352 percent, figures ranked by the industry publication Alpha. Across the firm, Paulson & Co. reportedly generated more than $15 billion gross for its funds, and Paulson personally was paid about $3.7 billion, with some accounts placing his haul nearer $4 billion. That year he topped Alpha's list of the highest-earning hedge fund managers.

The Abacus deal is the part that later drew regulators. Abacus 2007-AC1 was a synthetic CDO that Goldman structured and closed on April 26, 2007. Its value depended on a reference portfolio of subprime mortgage bonds. According to the SEC's complaint, Paulson helped pick the bonds in that portfolio and then bought CDS protection against the same portfolio, a bet it would fail. Investors who took the other side lost more than $1 billion as the underlying bonds were downgraded, and Paulson's short reportedly gained about $1 billion. Paulson paid Goldman a fee of roughly $15 million to arrange the structure.

Why It Happened

The Paulson subprime trade worked because of an asymmetry the market had mispriced. A CDS on a subprime bond cost a small annual premium, but if the bond defaulted the payout was many multiples of that premium. In 2005 and 2006 the premiums were tiny, because rating agencies and most investors treated diversified pools of home loans as safe. Paulson saw that the loans inside those pools were not safe at all. Many carried teaser rates, little documentation, and were made to borrowers who could only keep paying if home prices kept rising.

The second reason was conviction under pressure. The position lost money for over a year, and Paulson faced doubt from investors who thought he had misread the housing market. Because his downside was capped at the premiums he paid, he could hold the bet without risk of a margin spiral wiping him out. That structure let conviction survive a long, painful wait. When defaults finally spread, the same leverage in the payoff that had looked like a slow bleed turned into an explosive gain.

The Abacus controversy turned on disclosure, not on Paulson's market call. Synthetic CDOs need someone on each side: a party that is long the reference bonds and a party that is short. There is nothing unlawful about being the short. The SEC's case was that Goldman's marketing materials told investors the reference portfolio was selected by ACA Management, an independent firm, without disclosing that Paulson, a hedge fund betting the portfolio would fail, had helped choose what went into it. SEC enforcement director Robert Khuzami framed the distinction plainly: "Goldman made representations to investors, and Paulson did not." That sentence is why the firm that built the deal was charged and the firm that profited from it was not.

Aftermath

Paulson was not charged with any wrongdoing. The SEC's April 16, 2010 complaint named only Goldman Sachs and its vice president Fabrice Tourre as defendants. Khuzami's reasoning was that the legal duty to disclose ran to whoever made representations to investors, and that was Goldman, not Paulson, who had no relationship with the buyers. Paulson kept the gains from both Abacus and his broader subprime short.

Goldman settled. On July 15, 2010, the firm agreed to pay $550 million, then the largest penalty an SEC enforcement action had ever extracted from a Wall Street firm. The payment was structured as a $15 million disgorgement and a $535 million civil penalty, with about $250 million routed to harmed investors and about $300 million to the U.S. Treasury. Goldman did not admit or deny the SEC's allegations. It did acknowledge that its Abacus marketing materials contained "incomplete information," and that it was "a mistake" to state the portfolio was selected by ACA without disclosing Paulson's role and adverse economic interest.

The case against Tourre went to trial. On August 1, 2013, a Manhattan federal jury found him liable on six counts of civil securities fraud, a rare courtroom win for the SEC against an individual tied to the crisis. He was later ordered to pay roughly $825,000 and was barred from parts of the industry. He left finance and pursued an academic career.

Paolo Pellegrini, the analyst widely credited with finding the subprime opportunity, left Paulson & Co. in December 2008 to start his own fund. Paulson stayed prominent for years, though later bets, including a large gold position, did not repeat the 2007 result. The trade itself became the subject of Gregory Zuckerman's book "The Greatest Trade Ever," cementing the name that still attaches to it. The wider story, the subprime collapse it bet on, became the 2008 global financial crisis.

Lessons for Investors

1. Asymmetric payoffs let you be wrong for a long time. Paulson's CDS premiums capped his loss while leaving the upside open. Because his maximum loss was the premium, a year of being early did not force him out. When you can define your downside in advance, you can hold a contrarian view through the stretch where the crowd says you are crazy.

2. A consensus rating is not the same as safety. The subprime bonds Paulson shorted carried high credit ratings, yet the loans inside them were fragile. He looked through the label to the cash flows and the borrowers. Treat a rating or a market price as a claim to verify, not a fact to accept, especially when everyone agrees the asset is safe.

3. Being short is legal; hiding who is short can be the problem. Paulson's bet against Abacus broke no rules. The SEC's case was about what Goldman told buyers, not about Paulson's position. When you evaluate a structured product, ask who sits on the other side of your trade and whether their incentives were disclosed to you.

4. Conviction needs a survivable structure, not just a strong opinion. Paulson's view would have been worthless if a margin call had forced him to close before the payoff arrived. The instrument he chose let the thesis outlast the doubt. Size and structure a contrarian bet so a long wait or a drawdown cannot end it prematurely.

5. One great trade is not a permanent edge. The 2007 win was historic, but Paulson's later large bets did not reliably repeat it. A single spectacular outcome can owe as much to a rare setup as to repeatable skill. Judge a track record across many independent decisions, not by the one that made the headlines.

Frequently Asked Questions

What was the Paulson subprime trade in simple terms? The Paulson subprime trade was John Paulson's 2006 to 2007 bet that subprime mortgage bonds would collapse, made by buying credit default swaps that paid off when those bonds failed. It earned his firm more than $15 billion in 2007.

Why did the Paulson subprime trade work? Paulson saw that subprime mortgage bonds were far riskier than their high ratings and low prices implied. Credit default swaps let him short them cheaply, with a capped cost and a huge payoff, so when defaults spread in 2007 the protection he held soared in value.

How much money did Paulson make on the subprime trade? His firm reportedly earned more than $15 billion gross in 2007, and Paulson personally was paid about $3.7 billion, with some accounts citing closer to $4 billion. One of his credit funds returned roughly 590 percent net that year.

Was John Paulson charged over the Goldman Abacus deal? No. The SEC charged Goldman Sachs and its employee Fabrice Tourre, not Paulson & Co. Goldman settled for $550 million without admitting or denying wrongdoing, and the SEC said the disclosure duty ran to Goldman because Goldman, not Paulson, made representations to investors.

What is the main lesson from the Paulson subprime trade? The core lesson is that an asymmetric, well-structured bet lets you hold a contrarian view long enough to be right. Paulson's capped downside and open upside let his conviction survive more than a year of losses before the payoff arrived.
