The difficulty is somewhat artificial. Their statements give away the game, namely their obsession with a "soft landing." Translation: an undue focus on securities markets and saving entities who'd made bad investments, i.e., picking winners. They were late because they were trying to balance a factor that isn't part of their quasi-mandate (but that is important to politicians, and to the institutions that Fed officers revolving doored from). Without that factor, you see radical hikes in 2021 and QT not being undermined by waves hands vaguely. It hurts, but less than what's coming now.
