When Dr. Alan Greenspan became Federal Reserve Chairman after his predecessor Paul Volcker, the Fed had substantial influence. This significant moment was noted in the book “The Secret of the Temple,” published in 1987.
Even though Greenspan had his reservations about extensive government intervention, he significantly enhanced the Fed’s authority during his lengthy tenure. He expanded the chairman’s powers, engaged actively with the Bank for International Settlements, and endorsed international banking standards via the Basel Accords. He almost doubled the Fed’s workforce in Washington, D.C., raising the numbers to over 3,000 employees.
One of his key contributions was altering the Fed’s strategy regarding monetary policy. He shifted away from Volcker’s focus on a strict money supply management to a more data-driven approach, emphasizing the targeting of monetary policy.
Greenspan had a reputation as a bit of a data enthusiast. He utilized various metrics, like rail car loads and production tonnage, to help decide the federal funds rate. Occasionally, he looked at commodity price indexes, reflecting his background in advocating for stable monetary systems. This methodology gradually evolved into formal inflation targeting in 2014, but during the 1990s and early 2000s, financial markets largely relied on Greenspan’s quick analysis and understanding of data.
In 1996, he cautioned Wall Street about what he termed “irrational exuberance” during a flourishing economy marked by a peace dividend and tax cuts championed by Newt Gingrich. Investors were attentive to his warning, but enthusiasm persisted until the dot-com crash in 2000. Over time, his views on asset bubbles shifted, leading him to tell Congress in 1999 that while human behavior tends to excess, economic policymakers should work to cushion the impacts when they arise.
Under his guidance, the Fed became known for its prompt provision of emergency liquidity, famously referred to as the “Greenspan Put.” His first major test came soon after he took office on Black Monday, October 19, 1987, when the market plummeted by 23% in just one day. In response, the Fed quickly increased reserves, which alleviated banks’ restrictions on lending. This action led to a decline in the federal funds rate shortly thereafter. In response to the market crashes of 1998 and 2000, the Fed took aggressive action, slashing interest rates to bolster financial stability. This period was chronicled in his 2000 book, “Maestro: Greenspan’s Fed and America’s Boom.”
Since Greenspan stepped down in 2006, the Fed’s role has expanded. He had proposed that the Fed pay interest on bank reserves, a policy that was implemented sooner than anticipated during the 2008 financial crisis. The Fed’s responsibilities now include bond purchases, a standing repurchase facility, and ensuring adequate bank reserves that grow alongside the economy. Regulatory authority has also broadened significantly, from pre-Greenspan leverage ratios to modern comprehensive liquidity requirements.
Overall, the Fed is now much more intertwined with fiscal policy than during Greenspan’s leadership, facing challenges like duration mismatches and a prevalent role in the repo market. While Greenspan elevated the Fed’s stature, he couldn’t resolve some of the underlying economic issues. The future of this evolution rests on the current Fed and its Chairman, Kevin Warsh, who will need to consider how best to utilize data-driven insights to achieve price stability—something Greenspan pondered deeply during his long career.
