do you think it’s feasible for them to go full Volcker if that’s what it takes to beat back inflation?"US inflation, which peaked at 14.8 percent in March 1980, fell below 3 percent by 1983...Volcker raised the federal funds rate, which had averaged 11.2% in 1979, to a peak of 20% in June 1981" [1]. For comparison, we're currently around 8.5% [2] and 0.75% to 1%, respectively. Long-term rates are below 4% [3].
There is no need to tip the economy into a recession at this time. If we needed to, the constraint would be--as it was in Volcker's time--political. If we were suffering double-digit inflation, I suspect the will would be there.
