In this May 22 2020 article, NYU Stern Prof. Nouriel Roubini (BA Bocconi University 1982, PhD Harvard 1988) proclaimed:
In other words, you’re saying that because of structural weaknesses in the economy, even modest inflation would be crisis-inducing because key economic actors are dependent on near-zero interest rates?
For the last decade, debt-to-GDP ratios in the U.S. and globally have been rising. And debts were rising for corporations and households as well. But we survived this, because, while debt ratios were high, debt-servicing ratios were low, since we had zero percent policy rates and long rates close to zero — or, in Europe and Japan, negative. But the second the Fed started to hike rates, there was panic.
In December 2018, Jay Powell said, “You know what. I’m at 2.5 percent. I’m going to go to 3.25. And I’m going to continue running down my balance sheet.” And the market totally crashed. And then, literally on January 2, 2019, Powell comes back and says, “Sorry, I was kidding. I’m not going to do quantitative tightening. I’m not going to raise rates.” So the economy couldn’t take a Fed funds rate of 2.5 percent. In the strongest economy in the world. There is so much debt, if long-term rates go from zero to 3 percent, the economy is going to crash.
Roubini's ostensibly paraphrasing Chair Jerome Powell informally. Is Roubini correct? What exactly did Powell communicate in Dec 2018 and Jan 2 2019?
