Stocks in China and Hong Kong rebounded, tracking gains in overnight trading in New York. 

The Hang Seng Index increased 1.7%, and the mainland-focused CSI 300 index advanced 1.3% as bargain hunters returned.

Technology stocks led gainers in Hong Kong, and financials dominated trading in Shanghai ahead of quarterly results and international trade data. 

Investors reviewed the U.S. Supreme Court's oral arguments in tariff cases, and justices appear skeptical about the U.S. president's authority to impose sweeping tariffs without approvals from the U.S. Congress.

The Trump administration is likely to seek other ways to impose import taxes, but those taxes will be limited in scope and targeted to certain industries. 

The tariffs case filed by seven small businesses and 12 U.S. states led by Oregon was consolidated by the U.S. Supreme Court, and the court is set to announce its decision before the end of its term in July 2026.

The Trump administration's tariffs faced significant opposition from two lower courts, and they ruled them illegal.
