How One of the World’s Oldest Hedge Funds Went Bankrupt: The Fall of Amaranth Advisors

Amaranth Advisors, once a behemoth in the hedge fund world, met its ignominious end in 2006 due to a catastrophic series of natural gas trades. Specifically, excessive and highly leveraged positions in natural gas futures, primarily overseen by trader Brian Hunter, backfired spectacularly, resulting in losses exceeding $6.6 billion in a matter of days. This triggered a margin call the fund couldn’t meet, forcing it into liquidation and effectively bankruptcy, a dramatic fall from grace for a fund that had managed over $9 billion at its peak. The story serves as a stark reminder of the dangers of unchecked risk-taking, over-reliance on a single trader, and the inherent volatility of commodity markets.

The Rise and Fall: A Hedge Fund Tragedy

Amaranth Advisors was founded in 2000 by Nicholas Maounis and quickly gained prominence, employing a multi-strategy approach that included convertible arbitrage, fixed income arbitrage, and energy trading. The firm boasted sophisticated models and a team of experienced professionals, initially attracting significant investor capital and delivering impressive returns. However, the firm’s undoing was its increasing reliance on natural gas trading, particularly on the expertise of Brian Hunter.

The Brian Hunter Gamble: A Recipe for Disaster

Brian Hunter, a relatively young and ambitious trader, had a reputation for making bold and profitable calls on the natural gas market. He joined Amaranth in 2003 and quickly became the firm’s star trader, generating substantial profits through his positions in natural gas futures. Hunter’s strategy involved exploiting the spread between natural gas prices for different months, a strategy that could yield significant returns but also carried substantial risk, especially when magnified by leverage.

Hunter’s positions were primarily focused on the Katy Hub, a major delivery point for natural gas in Louisiana. He amassed enormous positions, betting that the price spread between the March and April 2007 natural gas futures contracts would narrow. This was based on his belief that colder weather in the Northeast would drive up demand for natural gas in March, causing the March contract to rise relative to the April contract.

The Market Turns: The Beginning of the End

The problem? The weather didn’t cooperate. The winter of 2006 was milder than expected, leading to lower demand for natural gas. This caused the price of the March 2007 contract to fall, while the April 2007 contract remained relatively stable. This widening of the spread between the contracts resulted in massive losses for Amaranth.

As losses mounted, Amaranth attempted to double down, increasing its positions in an attempt to recoup its losses. This only exacerbated the problem, creating a vicious cycle of losses and escalating risk. The size of Amaranth’s positions became so large that they began to distort the natural gas market, drawing scrutiny from regulators and other market participants.

The Margin Call and Liquidation

By September 2006, Amaranth’s losses had become unsustainable. The fund faced a massive margin call, requiring it to deposit billions of dollars to cover its losses. Unable to meet the margin call, Amaranth was forced to liquidate its positions.

The sheer size of Amaranth’s holdings meant that the liquidation process had a devastating impact on the natural gas market. Prices plummeted, further compounding Amaranth’s losses. Ultimately, the fund was forced to sell off its assets to other hedge funds, including Citadel LLC and JPMorgan Chase. The losses wiped out the majority of Amaranth’s capital, effectively bankrupting the firm.

Lessons Learned: Risk Management Failures

The collapse of Amaranth Advisors serves as a cautionary tale for the hedge fund industry and the broader financial world. Several critical failures contributed to the fund’s downfall:

• Inadequate Risk Management: Amaranth’s risk management systems failed to adequately monitor and control the risks associated with Brian Hunter’s positions. The firm allowed a single trader to accumulate excessively large positions that were highly leveraged and concentrated in a single commodity.

• Over-Reliance on a Single Trader: Amaranth became overly dependent on Brian Hunter’s trading decisions, giving him a level of autonomy that was disproportionate to his experience and the overall risk profile of the fund.

• Lack of Diversification: Amaranth’s increasing concentration in natural gas trading made the fund highly vulnerable to adverse movements in the natural gas market. The fund failed to adequately diversify its portfolio, increasing its exposure to a single, volatile asset class.

• Complacency and Hubris: Amaranth’s initial success bred a sense of complacency and hubris, leading to a disregard for risk management principles. The firm became overly confident in its ability to predict market movements and manage risk.

Frequently Asked Questions (FAQs)

Here are 12 frequently asked questions designed to provide further clarity and insight into the Amaranth Advisors debacle:

1. What exactly is a hedge fund?

A hedge fund is a privately managed investment fund that uses sophisticated and often complex investment strategies, such as leverage, short selling, and derivatives, to generate higher returns for its investors. They are typically available only to accredited investors due to their higher risk profile.

2. What is leverage and how did it contribute to Amaranth’s downfall?

Leverage is the use of borrowed money to increase the potential return of an investment. While it can amplify profits, it also magnifies losses. Amaranth used excessive leverage in its natural gas trades, which meant that even small adverse movements in the market could result in significant losses.

3. What are natural gas futures and how are they traded?

Natural gas futures are contracts that obligate the buyer to receive or the seller to deliver a specified quantity of natural gas at a predetermined price on a future date. They are traded on exchanges like the New York Mercantile Exchange (NYMEX) and are used by producers, consumers, and speculators to manage price risk or profit from price fluctuations.

4. Who was Brian Hunter and what was his role at Amaranth?

Brian Hunter was a key natural gas trader at Amaranth Advisors. He was known for his aggressive trading style and his ability to generate significant profits. However, his large and highly leveraged positions ultimately led to the firm’s demise.

5. What were the specific natural gas trades that led to Amaranth’s losses?

Hunter primarily focused on calendar spread trading, betting on the price difference between natural gas futures contracts for different months. His most significant positions involved the spread between the March and April 2007 natural gas contracts, expecting the spread to narrow due to anticipated colder weather.

6. What is a margin call and why was it so devastating for Amaranth?

A margin call occurs when the value of an investor’s account falls below a certain level, requiring the investor to deposit additional funds to cover potential losses. Amaranth faced a massive margin call it couldn’t meet, forcing it to liquidate its positions at a significant loss.

7. What impact did Amaranth’s liquidation have on the natural gas market?

Amaranth’s forced liquidation had a significant impact on the natural gas market, causing prices to plummet. The sheer volume of contracts being sold overwhelmed the market, creating a downward spiral that further compounded Amaranth’s losses.

8. Were there any regulatory investigations or legal actions taken against Amaranth or Brian Hunter?

Yes, the Commodity Futures Trading Commission (CFTC) investigated Amaranth and Brian Hunter for allegedly manipulating the natural gas market. Hunter was eventually fined and barred from trading futures.

10. Could this happen again? What safeguards are in place to prevent a similar situation?

While it’s impossible to guarantee that a similar event won’t occur, regulations and risk management practices have been strengthened since Amaranth’s collapse. Increased regulatory scrutiny, stricter capital requirements, and more robust risk management systems within hedge funds are intended to mitigate the risk of similar incidents. However, the inherent complexities of financial markets mean that the potential for catastrophic losses always exists.

11. Who ultimately lost money as a result of Amaranth’s bankruptcy?

The primary losers were Amaranth’s investors, which included pension funds, endowments, and high-net-worth individuals. Employees of Amaranth also lost their jobs and faced financial hardship.
