Supreme Court Limits Trump Power with Multiple Rulings

The Supreme Court issued several rulings on June 29, 2026, limiting President Trump's power to fire officials. Trump cannot fire Federal Reserve Governor Lisa Cook, while he can fire independent agency officials per the court's previous ruling. This decision underscores the court's emphasis on preserving the independence of certain government agencies.

The Supreme Court issued a set of June 29 rulings that markets read primarily through the lens of Federal Reserve independence. In a notable check on executive power, the Court held that the president cannot remove Fed Governor Lisa Cook without proper notice and due process, reinforcing the central bank's insulation from political pressure .

At the same time, the Court left intact the broader precedent of Humphrey's Executor as applied to other independent agencies, producing a mixed picture on the limits of presidential removal authority . The combination tempers concerns that the administration could quickly reshape monetary policy leadership, a tail risk that bond and rate markets monitor closely.

For investors, the Fed-independence signal is the market-relevant takeaway: durable insulation of monetary policymakers supports the credibility premium embedded in Treasury yields and the dollar. The watch items are any further litigation over agency removals and how the ruling shapes the administration's approach to upcoming Fed appointments.
