What the Testimony of 9/11 Reveals About Financial Market Reactions
The testimony of 9/11 includes transcripts from congressional hearings, the 9/11 Commission, and SEC filings that document how equities, bonds, and insurance markets reacted to the attacks. The NYSE and Nasdaq reopened on September 17, 2001, after the longest closure since the Great Depression, and the Dow Jones Industrial Average fell 684 points, or 7.1%, on the first trading day back, as detailed in the 9/11 Commission Report and related testimony available on the National Commission on Terrorist Attacks Upon the United States website 9/11 Commission Report. The testimony also records how the Federal Reserve, led by Chairman Alan Greenspan, cut the federal funds rate by 50 basis points on September 17, 2001, and again by 50 basis points on October 2, 2001, to stabilize liquidity and support the financial system.
Financial testimony highlights how insurance and reinsurance markets faced immediate claims related to the World Trade Center, with the Insurance Information Institute noting that insured losses ranged from $30 billion to $40 billion, and Lloyd's of London and other syndicates played a central role in underwriting those risks. Testimony from the SEC and industry groups shows that market surveillance systems flagged unusual trading activity in the days before the attacks, and the SEC's Inspector General later published reports analyzing those anomalies, which are cited in multiple official testimony records.
