When will the debt limit be increased?

The key fact is that the debt limit has already been raised once in this Congress, so the market question is really whether there will be another increase or suspension before year-end 2026. On the merits, I do not think the odds are low enough to justify a 24% Yes price. Congress has already shown it can clear debt-limit legislation when leadership decides it is necessary, and the existence of bipartisan discussion around a longer-term fix suggests the issue is live rather than dormant. Even though Treasury is not expected to hit the ceiling until 2027, lawmakers often act before a binding cash deadline if they want to avoid market disruption or use the debt limit as part of a broader negotiating package.

The main reason to keep the probability below 50% is timing. If the practical breach window is in 2027, there is less forcing pressure in 2026 than in the classic debt-ceiling standoffs, and that reduces urgency. There is also real political friction: some Democrats are resisting another short-term extension, and earlier efforts to suspend the limit until January 2027 reportedly failed. Those facts make it plausible that Congress simply leaves the issue for the next session or handles it only if fiscal negotiations create a larger deal.

Even so, the market looks too pessimistic. The volume is not huge, and a 24% price implies investors think the issue is mostly dormant, but legislative behavior in Washington is often preemptive rather than reactive. With bipartisan interest in a longer extension, normal legislative activity still continuing, and a history of eventually resolving debt-limit problems before the deadline, I think the more balanced view is that a bill before Jan. 1, 2027 is somewhat likelier than not to be at least seriously attempted and plausibly enacted. The market appears to be underweighting the chance of a year-end legislative package or a broader budget bargain that includes a debt-limit change.
