I am going to sidestep the points about fiscal policy (TCJA, the various COVID relief bills) and concentrate on monetary policy *now.* Those fiscal measures (wise or not) are all water under the bridge.
I said 150 bp to 250 bp, so as much as 2.5%. Which, on the high end, would mean a ~45% increase in rates. Imaging taking
a 30-year fixed from its present 7.23% up to 9.75% or so.
I agree with you an economy can prosper under different inflation rates. Heck,
the British economy of the late 19th Century (and the U.S. one to some similar extent) grew quickly under strongly deflationary conditions as industrialization and increased silver production flooded markets with cheap products.
What makes effective monetary policy isn't as much the (
somewhat arbitrary, more on that in a moment) target rate chosen. What makes it work is consistency and commitment to the target. Lenders and debtors negotiate terms with the knowledge they need to adjust nominal APRs to a real APR by subtracting the predicted inflation rate. When that target is known and adhered to, this is easy. When it is unknown, you leave room for a great deal of uncertainty about how these loans are going to work out and market efficiency would decrease.
Those markets work better when they know the
real time-value of money.
As for the 2% target, I believe the idea was always...
(1.) Inflation is a regressive transfer of income. It is easy for the relatively affluent, college-educated professionals who post here (at least from what I've gleaned of CF's socioeconomics) to scoff at 2% versus 4%, but that a real impact when compounded for low-income people who don't have sources of income that are indexed to beat inflation (e.g., equities, real estate, etc.) the way the affluent can.
(2.) 2% is low enough to be "tolerable" for #1 but not so low it would leave the Fed with no room to maneuver if something disastrous (such as a fun pandemic!) were to inevitably happen.
I never said the Fed's job was easy. I'd be a bit more hawkish than they've been so far. And I think they will be come late 2024 and early 2025 (adjusting for whatever change in conditions by then).
