Understanding the complex interplay of economic policy and market dynamics leading up to significant financial events is crucial for grasping the larger picture of our nation’s economic history. The period from 2004 to 2007 offers a compelling case study, intertwining Federal Reserve actions with the burgeoning risks in the financial sector, particularly those related to subprime mortgages and credit default swaps. Let’s delve into these interconnected developments, drawing directly from the detailed accounts provided in our sources.
The narrative begins with the Federal Reserve’s interest rate policy between 2004 and 2005, a period when long-term interest rates showed surprisingly little movement even as the Federal Reserve incrementally increased the federal funds rate from 1 to over 4 percent. During these years, Federal Reserve Chairman Alan Greenspan maintained the belief that the country faced a risk of deflation. However, as critics accurately pointed out, this was a misjudgment. Deflation is highly improbable in an economy characterized by a substantial budget deficit, a long-term depreciating currency, and positive money growth. This expansive monetary policy, marked by a federal funds rate of 1 percent that kept the real short-term interest rate negative in an expanding economy, effectively permitted a significant credit expansion. This expansion concentrated heavily in the mortgage market. The Federal Reserve’s concern for deflation at this time delayed increases in the federal funds rate, a decision that contributed directly to a subsequent rise in housing prices and a substantial expansion of housing credit, often at low introductory rates. Indeed, the historically low interest rates were a key seed of disaster, creating a liquidity bubble.
Concurrently, the financial markets were undergoing significant transformations, with the rise of collateralized debt obligations (CDOs) and credit default swaps. In the early 2000s, Wall Street devised a “fantastic bait and switch” by applying formulas designed for corporate credit risk to consumer credit risk. Initially, these financial instruments were used to insure diversified piles of loans, including credit card debt, student loans, auto loans, and prime mortgages. The logic was that, given their diversity, these loans were unlikely to all go bad at once. However, by the end of 2004, a significant shift occurred: the composition of these “consumer loan” piles insured by companies like AIG Financial Products (AIG FP) moved from being only 2 percent subprime mortgages to a staggering 95 percent subprime mortgages.
It is within this context that Joseph Cassano’s unit at AIG FP became a major player in writing credit default swaps by early 2005, prompting him to question how their volume had grown so quickly. These swaps were essentially insurance policies against default, and AIG, with its coveted triple-A credit rating, became the go-to provider. The company essentially bought $50 billion in triple-B-rated subprime mortgage bonds by insuring them against default, a fact largely unacknowledged internally. For those involved, like Cassano, receiving insurance premiums for selling default protection on highly rated bonds seemed like “free money”.
As the market continued its trajectory, by the end of 2005, AIG made a critical decision: it stopped underwriting insurance on CDOs with subprime mortgage-backed securities. This decision was perceived internally as avoiding the “most toxic CDOs issued over the following two years”. While this action might seem prudent in retrospect, it meant AIG left itself exposed to the $50 billion worth of credit default swaps it had already sold, doing nothing to offset this substantial risk. The underlying problem, as some insiders like Gene Park began to realize in mid-2005, was that the quality of these subprime loans was “frighteningly poor”. Park’s private survey revealed that the supposedly diversified piles of consumer loans consisted almost entirely of U.S. subprime mortgages, a fact largely unknown to key AIG FP personnel, including Cassano, who believed home prices could “never fall everywhere in the country at once”. The entire financial system, it appeared, was premised on this collective ignorance.
By August 2007, Joseph Cassano’s confidence remained unshaken, as he publicly told investors that it was “hard for us, without being flippant, to even see a scenario within any kind of realm of reason that would see us losing $1 in any of those transactions”. His boss, Martin Sullivan, echoed this sentiment, stating it allowed him to “sleep a little bit easier at night”. This was despite the fact that, just a month earlier, Federal Reserve Chairman Ben Bernanke himself had acknowledged “downside risks to growth” and that credit markets were beginning to suffer as the housing bubble deflated.
By December 2007, Martin Sullivan was still boasting to investors at the Metropolitan Club in Manhattan that AIG was “one of the five largest businesses in the world,” stressing that the company did not rely on asset-backed commercial paper or securitization markets, and had the “ability to hold devalued investments to recovery”. He acknowledged AIG’s large exposure to “super-seniors” credit derivatives but believed the probability of sustaining an economic loss was “close to zero”.
However, behind these confident public pronouncements, the reality was starkly different. Market confidence in CDOs had already collapsed, and credit-rating agencies were downgrading tens of billions of dollars worth of CDOs, even those previously rated triple-A. Major clients like Goldman Sachs were demanding billions in additional collateral from AIG, signaling a growing dispute over asset valuations. By early 2008, AIG’s internal audit revealed “material weakness” in its accounting methods and a revised loss estimate soaring to over $5 billion. The apparent “free money” from credit default swaps had effectively made AIG the “world’s biggest owners of subprime mortgage bonds,” a position that would soon prove catastrophic.
In essence, the Federal Reserve’s sustained low interest rates fostered an environment ripe for credit expansion and a housing bubble. This, in turn, fueled the subprime mortgage market, which was then packaged into increasingly complex and poorly understood financial products. AIG’s aggressive foray into insuring these products, coupled with a deep-seated confidence in their supposed risklessness, created a massive vulnerability. Even as the housing market began to show cracks, a combination of ignorance, misplaced confidence, and a systemic failure to grasp the interconnectedness of risks left the financial system poised for the eventual widespread collapse, despite optimistic assurances from key figures within AIG and, initially, from policymakers. The actions and perceptions during this period ultimately laid the groundwork for the more severe financial crisis that unfolded in 2008.
