In a stunning rebuke to executive overreach, the Supreme Court today ruled unanimously that President Trump cannot dismiss Federal Reserve Board member Lisa Cook without cause. The decision, a rare moment of judicial clarity in an age of political chaos, reaffirms the independence of the central bank from the whims of the White House. For markets, this is more than a legal technicality: it is a bulwark against the kind of cronyism that erodes institutional credibility and, ultimately, the value of the pound.
The case, Trump v. Cook, centred on the President’s argument that Article II of the Constitution granted him unfettered authority to remove any executive branch official. The Court disagreed, citing the Federal Reserve Act’s explicit provisions for ‘for cause’ removal and the necessity of insulating monetary policy from short-term political pressures. Chief Justice Roberts wrote: ‘The power to set interest rates is not a toy for the Chief Executive. It is a sacred trust, shielded from the caprices of the electoral cycle.’
The immediate market reaction was telling. Gilts rallied, with the 10-year yield falling 12 basis points to 1.87%, as investors breathed a sigh of relief that Fed Chairman Powell would not be forced to work alongside a President who views independent regulators as obstacles. Sterling gained half a cent against the dollar, reflecting reduced political risk premia. The FTSE 100 climbed 0.8%, led by financials, as the shadow of White House interference receded.
Let us be clear about what this verdict means for the bottom line. Lisa Cook, a respected economist with a focus on employment and inflation, can now continue her work without the sword of Damocles hanging over her. Her research on how monetary policy affects minority communities is exactly the kind of granular analysis that a responsible central bank needs. To fire her for political convenience would have been an act of fiscal vandalism.
The dissenters, notably Justice Thomas, argued that the ruling creates a ‘fourth branch of government’ unaccountable to the electorate. But this is poppycock. The Fed is already accountable to Congress, which holds quarterly hearings and can amend the Federal Reserve Act at any time. What the Court has protected is the operational independence that has made the Fed the envy of central bankers from Zurich to Tokyo. Without it, we risk spiralling into the kind of currency crises that plague emerging markets.
The timing is exquisite. With inflation still above target at 3.2% and the labour market tighter than a drum, the Fed needs every ounce of credibility to navigate the next rate decision. A political firing would have spooked bond markets, sent the dollar into a tailspin, and forced the Bank of England to raise rates faster than it would like. Instead, we have a temporary reprieve from the age of the tariff and the tweet.
Will the President appeal? His legal team has already hinted at seeking an amendment to the Federal Reserve Act. But that would require a supermajority in a divided Congress, which is about as likely as a surplus in the current budget. For now, the City can sleep a little easier, knowing that the independence of the central bank is not a fiction sold by academics but a constitutional reality. It is not often that we praise the Supreme Court for anything, least of all in an election year. But today, they did their duty. The bottom line: the Fed remains independent, and the markets are better for it.
