New Federal Reserve chair Kevin Warsh has his work cut out

New Fed chief Kevin Warsh will have to make it clear that he, not Trump, is in charge at the US central bank. If he doesn’t, the US dollar and Treasury bills sell-off will start up all over again – perhaps more savagely, says Matthew Lynn

Donald Trump has picked Kevin Warsh as the new chairman of the Federal Reserve, the US central bank, after months of very public arguments. The markets liked the choice. Equities rose on the news and gold tumbled as investors decided they no longer needed to hedge against the collapse of the dollar. Warsh is an experienced banker and policy-maker, but he is also close to the Trump circle, and in the past has advocated bold reforms of the way monetary policy is set. Given that Trump could easily have appointed Elon Musk, or one of his children, or even Melania, Warsh is seen as a relatively safe pair of hands.

Still, the challenges Warsh faces are daunting. First, he will have to re-establish the independence of the central bank. Trump has very clearly been trying to bring the Fed under political control, pushing it to cut interest rates even though it is far from certain that inflation is not going to start rising again. The incumbent, Jerome Powell, is facing legal action for overspending on the Fed’s new headquarters. The markets are not going to trust a Trump stooge and especially one who looks willing to start printing money to finance the president’s lavish spending and tax cuts. At some point, Kevin Warsh will have to make it clear that he is in charge, not the president. If he doesn’t, and if he seems to be conceding to Trump’s demand to juice the economy, especially ahead of the mid-term elections due later this year, the sell-off of the dollar, and Treasury bills, will start up all over again, and perhaps more savagely.

Next, Warsh needs to persuade both the White House and Congress that the deficit genuinely matters. The US economy is in robust health, but the budget deficit is still running at more than 5% of GDP and there are no plans to bring it under control. The US state has become addicted to borrowing to finance its spending. The last president to actually balance the books was Bill Clinton at the start of the century. The US has managed to get away with it so far, racking up bigger and bigger debts with every year that passes. But it has benefited from its reserve currency status, and it has been able to mop up huge amounts of Chinese savings. None of that will necessarily last forever. Warsh needs to find a way of getting the Senate, Congress and White House to control spending and, if necessary, raise taxes. The US can’t run deficits forever without risking ruinous inflation.

Thirdly, the new Fed chair needs to reinvent the dollar for a post-globalisation world. Trump has made it clear he does not want the US to finance the global trading system, that he is determined to bring free trade under control, and he wants to put America first. That is why he has ripped up the free-trade consensus and imposed the steepest tariffs since the 1930s. Whether the dollar can remain the global reserve currency in those circumstances is far from clear. Indeed, there is already evidence that central banks around the world are diversifying into gold and even bitcoin. The European Central Bank is too weak to influence anything, but China is carving out a global role for the yuan, and that is only going to grow in significance. What is the role of the Fed in all of that? Warsh will need answers, or else be left floundering as the world changes around him.

Kevin Warsh will need to calm the AI bubble

Finally, Kevin Warsh needs to calm an AI and tech bubble that has run out of control. AI is clearly a major new technology, and will create huge business opportunities, but it is also clear that investors have driven valuations far too high, just as they did at the height of the first internet boom a quarter of a century ago. Likewise, a handful of leading tech stocks have dominated the global markets. Sure, it will be great for the US economy that so much money is invested in the technology, with more than $100 billion poured into data centres and start-ups over the last year. It will pay off eventually in terms of new products and higher productivity, and it is a lot more impressive than anything that is happening in Europe. Even so, a crash will derail that, and once it starts may easily run out of control. The trick for Warsh will be to curb what one of his predecessors, Alan Greenspan, described as “irrational exuberance” without the entire market collapsing. It will not be easy. But he will have to try all the same. If the bubble carries on for another year, it will be too late.
