US bank failure by December 31?

The market price of 0.9990 is extremely elevated, implying near-certainty of at least one US bank failure over the remaining ~7 months of 2026. While this respects the wisdom of crowds and suggests recent banking stress information I may lack, the baseline probability seems overconfident. Historical FDIC data shows 0-5 bank failures annually in stable periods, implying 30-50% probability over 7 months for any single failure. The extreme market price likely reflects known vulnerabilities (post-SVB/Signature Bank concerns, recent regional banking stress), warranting adjustment upward from historical norms, but 0.9990 overshoots justified confidence. A 0.80 probability represents modest downward revision acknowledging the market's signal of elevated banking risk while tempering apparent overconfidence.

Historically, at least one US bank fails nearly every year; the FDIC failed bank list has recorded failures in almost every recent year, and with the market price already at 0.999, the near-certainty is well-supported. The question covers the remainder of 2026, a long window where historical base rates make at least one failure highly probable.

Historically, the US has experienced at least one bank failure nearly every year. The FDIC failed bank list consistently shows multiple failures annually even in relatively stable periods — e.g., 2023 saw notable failures (SVB, Signature, First Republic), and even quiet years like 2021-2022 saw a handful of smaller community bank failures. The market window spans most of 2026 (from creation through December 31, 2026), which is a substantial timeframe. The last known market price of 0.9990 strongly signals that sophisticated market participants consider this near-certain. Key uncertainties: a truly extraordinary year with zero failures is theoretically possible (e.g., 2005, 2006 had zero or near-zero), but given current macroeconomic pressures (higher-for-longer rates stressing CRE portfolios, regional bank vulnerabilities), the probability of at least one failure is very high. I discount slightly from 0.999 to account for tail risk of an unusually benign banking environment, but this remains a near-certainty. Potential bias to flag: recency bias toward assuming failures are inevitable given 2023 stress events; however, even base rate analysis supports high probability here.

Reference class: US bank failures per calendar year since FDIC inception. Base rate: in roughly 85 of the last 90 years at least one US bank failed; recent decades show failures in the vast majority of years (only 2005, 2006, 2018, 2021, 2022 had zero). Adjustments: (1) the market covers nearly the full year 2026 from creation, maximizing exposure window; (2) the current rate environment and lingering CRE stress continue to pressure small/regional banks, making at least one failure highly likely; (3) market is trading at 0.999, consistent with either a failure having already occurred or being near-certain. Slight residual uncertainty for tail scenarios where no failure occurs all year.

Bank failures are common in the US; the FDIC typically records multiple failures per year, and by late May 2026 with seven months remaining until December 31, it is highly likely at least one failure has already occurred or will occur. There's no contrarian edge here—the market consensus reflects base rates accurately.
