A nova is a spectacular astronomic phenomenon. Although I am no astronomer, I've been told it occurs when a star is about to deplete its nuclear fuel. The mass in its outer layers fall inwards, becomes superheated and supercharged, so that the entire star explodes. When the turn eventually comes to our sun, its nova is expected to engulf the earth. This does not last long, however. In a matter of days, the plasma will fall back to the center of the sun, which then will be reduced to a red dwarf.
I am starting to get the feeling that President Trump, or the U.S. economy under his rule, is about to go nova. One three levels.
First, in the very short run, we certainly have seen a lot of activity and a lot of noise, with far-reaching initiatives, such as the immigration ban, the pull-out of the TPP, the condemnation and renegotiation of the NAFTA, and the infamous phone conversations with the Mexican President and the Australian Prime Minister. Glowing plasma indeed. But the reaction has already come in the form of numerous legal challenges and loud protests from around the world. Mr. Trump had to backtrack, at least a little, to say that he didn't intend a total ban on Moslems (which he did, according to Rudy Giuliani), and that green card holders are exempt. Not much, perhaps, and certainly no red dwarf yet; but Mr. Trump already gets to see some of the limits to his power.
Second, in the slightly longer run, Trump is looking to stimulate the U.S. economy, to create jobs and double the growth rate. The main instruments seem to be protectionist measures and deregulation, although fiscal expansion remains a possibility, at least large tax cuts. It may work. The trouble is that the U.S. economy is already at full employment; and none of Mr. Trump's proposals seem likely to raise productivity growth very much. So, if he succeeds, the result will be overheating; and the Fed will have to step in with sharply higher interest rates to stem inflation. I just hope that the overheating starts before the new financial deregulation gives us a new financial crisis.
Third, and most seriously, his protectionism risks sending the global economy into a bad, negative spiral. The first effect is the disruption of global value chains, which we are starting to see already as a result of his immigration ban. Then comes higher prices for U.S. consumers and significant job losses in other countries around the world. The final result may be a trade war, with retaliating tariffs and competing devaluations of a kind we have not seen since the 1930s. Unless Mr. Trump is stopped, which I still sincerely hope, the global economy may really start to resemble a red dwarf.
So, why has the stock market been so jubilant after the election? Well, for one thing, the stock market values earnings after tax, and he has promised steep tax cuts. Deregulation will also be good for many companies, although in many cases bad for the economy. The stock market does not reflect the entire economy, only the profits going to the owners. But I also fear the stock market has moved ahead of itself. A new sobriety already seems to have set in. I expect more.
