It is a bizarre legal action. Jerome Powell, the chairman of the Federal Reserve, the US central bank, has been prosecuted over renovations of the Fed’s headquarters and may now face criminal charges. Given that it manages an economy worth $30trillion and the world’s reserve currency, it is hard to see that the $2.5billion spent on improving the Fed’s offices really matters much. Even so, Donald Trump has clearly decided to use it as a weapon for a full-scale assault on a Fed chairman he would prefer to get rid of.
Powell himself was clear that the legal attack was just a way of bringing the Fed to heel. “The threat of criminal charges is a consequence of the Federal Reserve setting interest rates based on our best assessment of what will serve the public, rather than following the preference of the president,” he said in a statement. In other words, it is a political attack on the Fed and an attempt to allow the president to control monetary policy. If Powell is removed from office by the courts, whoever is appointed to replace him will clearly be taking instructions directly from the White House.
That is a dramatic and dangerous development. This is not to deny that independent central banks are worthy of criticism. Over the past 30 years, they have become too powerful, too confident in their own abilities and too quick to print money. You can make a case that, instead of ensuring greater stability, which is what they were meant to do, independent banks have inflated a series of asset bubbles, indulged spendthrift politicians and prioritised trendy causes while allowing industry to be hollowed out. There is a case for reform. Still, there is a big difference between that and a power grab to hand the right to set rates to the White House.

There are two big problems with that. First, it looks as if Trump is determined to control interest rates himself, either directly, or else through a tame proxy at the Fed. That is not without precedent. In Britain, interest rates used to be set by the chancellor, but the result was that the UK had one of the worst records on inflation in the world before Gordon Brown made the Bank of England independent in 1997. And it is hard to think of a worse person to set rates than Trump. He is temperamental, he constantly changes his mind, he doesn’t listen to advice, and his falling approval ratings mean he will constantly try to cut rates to boost short-term demand. Even more seriously, if the president acquires the right to set rates, it’s hard to see how it will ever be given up. It is too major a power to surrender. The US will have a politicised monetary policy permanently.
How bad will it get under Trump?
Everything else the president is doing appears designed to stop the free market working and drive up prices. The US has already imposed the steepest tariffs since the 1930s, with an average levy on imports of 18%. Closing off its markets to global competition will only drive prices higher and quality down. Only last weekend, Trump promised to cap credit-card interest at 10%, the kind of populist policy you would expect from the far left. Trump has also started capping corporate investment in the housing market. He is directing the oil companies to invest in Venezuela regardless of whether there is an investment case for it or not (with oil at $50 a barrel, there probably isn’t). There does not appear to be a coherent plan, but a whole series of interventions to create markets rigged by the government. State-controlled economies always end up with higher prices.
Add it all up, and one thing is clear – sooner or later the US will see a major rise in inflation. How bad will it get? There is no way of knowing for certain, and it will depend on what else is happening in the global economy. But once prices start to rise we know they are very hard to bring under control again. And if US prices rise, that will drive global prices higher. We can expect inflation to spread to Britain and the rest of Europe very quickly. Investors are already positioning themselves for that, with the price of gold hitting record highs every week. Prices of defensive assets will inevitably go a lot higher.
