Bond volatility continued to explode last week due to growing contagion fears from U.S. banks. Last Monday, after a weekend in which the U.S. government intervened to protect depositors of Silicon Valley Bank and Signature Bank, the 2-year U.S. note yield experienced its biggest one-day fall since October 20th, 1987. Outside of U.S. hours, it dropped the most since 1982. That intraday drop of close to 60 basis points even exceeded the declines during the 2007-2009 financial crisis, the September 11th, 2001, terrorist attacks, and 1987’s Black Monday market crash. Gregory Staples, head of fixed income North America at DWS Group in New York told MarketWatch that the week’s decline in the 2-year U.S. yield came as the result of “de-risking of portfolios and draining of liquidity, stemming from concerns about the health of the U.S. banking system, exacerbated by questions about the future of Credit Suisse.” The ICE BofAML Move Index, which measures bond-market volatility, surged on Wednesday and Thursday to its highest levels since the fourth quarter of 2008, during the height of the Financial Crisis. Volatility then continued on Friday over concerns around First Republic Bank. This sent Treasury yields plunging, one day after they spiked on the news of a funding deal.
