In brief

  • Larry McDonald flags bond market parallels to 1987 Black Monday crash conditions
  • Alphabet and Oracle corporate bonds now yield above 7%, signaling market stress
  • Rising energy prices compound recession risk alongside elevated bond yields
  • Bonds are 'stealing market share' from equities, McDonald warns

Bond Yields at Extremes

Corporate bonds from Alphabet and Oracle are currently yielding above 7%, a level that mirrors the distress signals McDonald observed in 1987. Alphabet issued a 100-year bond in February 2026 that has already fallen to around 87 cents on the dollar, a sharp mark-down that reflects investor concern about credit quality and duration risk.

The parallels to three decades ago are stark. U.S. 10-year Treasury yields climbed to 9.89% in the summer of 1987, and U.K. 10-year gilts reached 10.12% that same period. Today's yield environment, though not yet at those extremes, is pushing in the same direction. Oracle's long-term debt is yielding in the 7% to 8% range, underscoring how far fixed-income returns have climbed.

The Equity Squeeze

McDonald's thesis centers on a rotation out of stocks. Bonds are beginning to "steal market share" from equities, he argues, as investors chase yield in safer instruments. This dynamic mirrors 1987, when the Dow reached an all-time high in August before collapsing nearly 23% in a single day on October 19.

Energy prices compound the risk. McDonald flagged rising energy prices as a second variable that amplifies recession risk, creating a two-front squeeze on corporate earnings and consumer spending. When bonds offer compelling returns and energy costs spike, equity valuations face headwinds from both sides.

The pattern isn't inevitable — markets don't repeat, they rhyme. But McDonald's warning deserves attention: when the bond market starts signaling distress, equities often follow.
