that it can issue debt in dollars, but the printing press is not a panacea. If investors become more reluctant to hold a country’s debt, they probably will not be too thrilled about holding its currency, either. If that country tries to dump a lot of it on the market, inflation will result. Even moving to a centrally planned economy (perhaps the goal for some MMT supporters) would not solve this problem. On Powell’s second point, that U.S. debt is already high and rising too fast, there is far more room for debate. True, debt cannot rise faster than GDP forever, but it may do so for quite a while. Today’s long-term, inflation-adjusted interest rates in the U.S. are about half their 2010 level, far below what markets were predicting back then, and far below Fed and International Monetary Fund forecasts. At the same time, inflation has also been lower for longer than virtually any economic model would have predicted, given current robust U.S. growth and very low unemployment. What’s more, despite being at the epicenter of the global financial crisis, the U.S. dollar has become increasingly dominant in global trade and finance. For the moment, the world is quite content to absorb more dollar debt at remarkably low interest rates. How to exploit this increased U.S. borrowing capacity is ultimately a political decision. That said, it would be folly to assume that current favorable conditions will last forever, or to ignore the real risks faced by countries with high and rising debt. These include
Unfortunately, the Fed itself is responsible for a good deal of the confusion surrounding the use of its balance sheet. ust as the U.S. Federal Reserve seems to have beaten back blistering tweets from President Donald Trump, the next battle for central- bank independence is already unfolding. And this one could potentially destabilize the entire global financial system. A number of leading U.S. progressives, who may well be in power after the 2020 elections, advocate using the Fed’s balance sheet as a cash cow to fund expansive new social programs, especially in view of current low inflation and interest rates. Prominent supporters of this idea, which is often referred to as “Modern Monetary Theory” (or MMT), include one of the Democratic Party’s brightest new stars, congresswoman Alexandria Ocasio-Cortez. Although their arguments have a grain of truth, they also rest on some fundamental misconceptions. Fed Chair Jerome Powell could barely contain himself when asked to comment on this new progressive dogma. “The idea that deficits don’t matter for countries that can borrow in their own currency I think is just wrong,” Powell insisted in his U.S. Senate testimony last month. He added that U.S. debt is already very high relative to GDP and, worse still, is rising significantly faster than it should. Powell is absolutely right about the deficit idea, which is just nuts. The U.S. is lucky
