Wall Street’s gyrations shook markets anew, with stocks wiping out losses to extend their best weekly rally since 2023. The rebound came as a selloff in longer-term Treasuries and the dollar abated, following a few chaotic days that underscored fears foreign investors are beating a retreat from American assets.

Volatility shows little signs of easing as concerns that President Donald Trump’s fast-evolving trade policy is not only shaking the global economy, but threatening the US status as the world’s safe haven. The S&P 500 jumped about 1.5% on a report that a Federal Reserve official said the central bank is ready to help stabilize markets, if needed. US 30-year yields were little changed, while still remaining up by 45 basis points since last Friday.
