The U.S. Supreme Court has declared that President Donald Trump's general tariffs are unlawful, illuminating a significant constitutional boundary regarding trade decisions. According to the ruling, it is Congress, not the president, that holds the authority to implement such tariffs. This decision underscores the checks and balances within the U.S. political system, especially regarding trade and economic policy.

In the wake of this ruling, economist Robert Bergqvist from SEB speculates that Trump may have an alternative strategy, dubbed 'Plan B,' to navigate around this legal hurdle. Bergqvist expresses a measured sense of reassurance in the Supreme Court's adherence to constitutional principles, suggesting that the conservative majority respects the legislative authority granted to Congress.

The implications of this ruling extend beyond the immediate tariffs at stake; they touch upon the foundational aspects of U.S. governance. If President Trump does pursue a plan B, it could lead to further legal scrutiny and potentially spark new political debates about executive power and legislative authority, ultimately affecting the country’s economic landscape.
