Warsh Rate Hike Signal Crushes Rate-Sensitive Sectors — But Banks Quietly Win

If the rate hike signal triggers a genuine credit cycle — rising loan delinquencies, commercial real estate defaults accelerating, or a yield curve inversion that signals recession within 6-9 months — then credit loss provisions would overwhelm NII gains. The observable signal to watch: if 30+ day loan delinquency rates in commercial real estate or consumer credit start rising more than 50bps quarter-over-quarter, the NII expansion thesis is overwhelmed by credit deterioration.

The strongest bear case is that Warsh's hike signal is itself a policy error signal — if the Fed hikes into a slowing economy, the probability of a hard landing rises sharply, which is the single worst outcome for bank credit quality. The specific assumption most likely to be wrong in the long thesis is that deposit costs remain sticky; if rate hikes cause deposit outflows to money market funds (as happened in early 2023 with regional banks), large banks could face funding cost pressure that erodes the NIM advantage. The data point that would flip conviction entirely: a sharp spike in money market fund inflows (>$200B in a single month) combined with rising 90-day delinquency rates in bank loan portfolios — that combination would signal the deposit repricing and credit deterioration scenario that breaks the thesis.

The 2022-2023 Fed hiking cycle is the cleanest analog. As the Fed raised rates from 0.25% to 5.25-5.50%, JPMorgan's net interest income grew from ~$44B in 2021 to ~$89B in 2023 — a near-doubling. Bank stocks initially sold off in 2022 alongside the broad market, then massively outperformed in 2023 as NII expansion became undeniable. Investors who bought US money-center banks during the 2022 rate-fear selloff and held 18 months captured 40-60% returns. The behavioral pattern at play is identical to what Charles Kindleberger described as 'displacement followed by over-reaction' — the market displaces a nuanced sector analysis with a simple narrative ('rates up = bad for everything') before eventually correcting to fundamentals. The 1994 rate hike cycle showed the same pattern: banks initially sold off on hike fears, then outperformed 12-18 months later as NIM expansion materialized.
