Motley Fool Warns S&P 500 Could Drop 10% as 30-Year Yield Hits 5.18%

Summary
A U.S. stock-market crash is plausible, Motley Fool said, with the biggest near-term risk coming if Fed rate hikes arrive alongside new tariffs.
History underpins the warning: since 1999, the S&P 500 and Nasdaq have typically fallen after the Fed begins tightening, with average peak-to-trough declines of 10% and 15% over three months.
Inflation has strengthened that case, with May CPI at 4.2% and PPI at 6.5%, fueling expectations the Fed could raise rates as soon as July even though consensus points to December.
Bond markets are flashing a similar signal after the 30-year Treasury yield jumped to 5.18% in May, its highest since 2007; the last time yields were that high, both major indexes later fell about 20%.
Trade policy adds another headwind: the U.S. Trade Representative has proposed 10% to 12.5% tariffs on 60 countries, with July 7 hearings ahead and economists broadly expecting broad tariffs to weigh on growth.

30-Year Treasury Yields Hit 19-Year High: Geopolitical Shocks, Inflation, and AI Shape the 2026 Market Outlook
Overview
In May 2026, financial markets were shaken as 30-year Treasury yields soared to a 19-year high, signaling heightened caution and potential volatility for investors. This surge in bond yields raised the risk of steep losses in the stock market, especially for major indices like the S&P 500. The current environment increased the likelihood of Federal Reserve rate hikes, particularly in response to external pressures such as energy shocks. Historically, such rate increases have often led to adverse economic outcomes, including pulling the U.S. economy into recession. These interconnected factors set a challenging stage for both investors and the broader economy.
