Clearly, a lot of those crisis responses would be unpalatable and some are not likely unless things get much worse. Many of them, of course, also have limits on their effectiveness. For example, while the Fed can control short-term policy interest rates, they don’t control risk premiums or interest rates on long-term securities. With high-commodity prices, nontrivial inflation risk, and turbulence in financial markets, long-term interest rates, including mortgage rates, have come down much less than short-term rates. As the Fed reduces short-term rates and signals its willingness to do more, the US dollar falls further and risks getting into.
