Stock Market Rises Amid SCOTUS Tariff Debate and Government Reopening Optimism
The S&P 500 ETF (SPY) and Nasdaq 100 ETF (QQQ) closed higher as the Supreme Court scrutinized President Trump's tariff authority under the International Emergency Economic Powers Act. Justice Sonia Sotomayor challenged the administration's stance, arguing tariffs function as taxes—a congressional prerogative. A ruling against TRUMP could trigger $90 billion in refunds, marking a historic decision with broad economic implications.
Market sentiment also improved on growing expectations of a government reopening. The Trump administration may pivot to alternative legal justifications, including Section 122 of the Trade Act of 1974, which permits 15% tariffs. Investors are weighing these developments against broader macroeconomic trends.
