2011 US Debt Ceiling & Downgrade
July–August 2011· Analysis last reviewed
S&P stripped the United States of its AAA credit rating on August 5, 2011, the first time in history. Markets whipsawed as the debt ceiling fight showed political risk could reprice government creditworthiness.
What Happened
The 2011 debt ceiling crisis was a political fight with market consequences. House Republicans refused to raise the debt ceiling without equivalent spending cuts. As the Treasury approached its borrowing limit, S&P downgraded US sovereign debt from AAA to AA+ on August 5, 2011, the first time in US history.
The market reaction was paradoxical. Despite the downgrade of Treasury debt, Treasury yields fell as investors fled to safety. The S&P 500 dropped 17% in two weeks. Gold rallied to $1,900/oz. VIX spiked above 45. The logic: a US fiscal crisis implied lower growth, which meant the Fed would stay easier longer, which pulled yields lower, even as the credit quality of the issuer was being questioned.
The episode taught a durable lesson about the reserve currency: when the ultimate risk-free asset is downgraded, there is nowhere else to go. Foreign investors continued to buy Treasuries despite the downgrade because no alternative offered sufficient depth. Political dysfunction priced into volatility and gold, not into Treasury yields. The dynamic would repeat in 2013 and 2023.
