Contracts for the S&P 500 and the Nasdaq 100 gained 1% after the underlying gauges slumped more than 2% in Monday’s session. Europe’s Stoxx 600 index dropped as traders returned from the Easter break, while Asian equities were little changed. An index of the dollar’s strength steadied after weakening to a 15-month low.

Investors are wading through a slew of headlines on tariff talks after Trump ratcheted up his global trade war this month by imposing the highest levies in a century. Concerns Trump may be preparing to fire Fed Chair Jerome Powell have increased unease among traders, who are looking ahead to earnings from Tesla Inc. and Alphabet Inc. this week for clues on how companies are navigating this new environment.

Trump’s tirades have forced a reappraisal of the assets fundamental to US economic dominance. The dollar and Treasuries, traditional havens at times of stress, suddenly look much less appealing.

The greenback was mixed against Group-of-10 peers Tuesday, while the yen outperformed, with the Bank of Japan said to be on course to keep raising rates. Meanwhile, China let the yuan weaken against almost all major currencies to support its economy as the trade war with the US deepens.
