Bond Yields Are Flashing a 1987-Style Warning, Says Ex-Lehman Trader

Former Lehman Bros. trader Larry McDonald says bond yields are starting to deliver "equity-like returns" — and he reads that as bad news for the stock market.

Speaking on The David Lin Report podcast, the Wall Street veteran said he sees parallels between the current environment and the months before Black Monday, the stock-market crash of October 1987.

The warning signal, in McDonald's framing, comes from the bond market rather than equities themselves. Yields are rising to levels where fixed income competes directly with stocks for investor capital, a dynamic he says resembles the setup during the summer of 1987, when climbing rates preceded the Dow's single-day collapse.

The market backdrop McDonald is commenting on is strained. The U.S. 10-year Treasury yield stands at 5.146%. The British 10-year gilt yield is at 5.391%. Equity indexes reflect the pressure: the Dow Jones Industrial Average trades at 51,511.59, down 0.68%. The S&P 500 sits at 7,706.03, off 0.75%. The Nasdaq Composite is at 26,936.04, lower by 1.13%. The VIX volatility gauge reads 16.52, up 8.83%.

Individual megacap names show the strain too. Alphabet (GOOGL) is down 3.80%, and Oracle (ORCL) is off 3.11%, according to MarketWatch data.

McDonald's call matters because of his track record and his vantage point. He traded at Lehman Bros. before the firm's collapse in 2008 and has built a reputation as a chronicler of systemic risk in credit markets. His argument — that bond yields now offer returns attractive enough to pull money out of equities — echoes the mechanism many historians cite ahead of 1987: rising rates eroding the relative case for holding stocks.

The data points around his warning compound the picture. Gold trades at $4,288.90 an ounce, down 0.68%. Crude oil sits at $93.73 a barrel, up 1.70%. Bitcoin stands at $83,241.71, lower by 1.48%. Across asset classes, the common thread is a repricing alongside elevated sovereign yields.

The reference to 1987 carries weight with market historians. Black Monday, Oct. 19, 1987, saw the Dow fall 22.6% in a single session, still the largest one-day percentage drop in its history. McDonald's contention is not that a repeat crash is imminent, but that the bond market's configuration — yields high enough to rival equity returns — resembles the setup that preceded it.

Investors watching for confirmation of his thesis will be tracking the 10-year Treasury yield around the 5.146% mark. If yields keep climbing and equities keep leaning on a narrowing group of large-cap names, McDonald's 1987 parallel will remain a live question for the market's next leg.
