Summary
The 2026 US midterms shift the policy outlook for banks, but rules and legislation take years to reach operations, longer than any Congress. Across capital rules, AI, digital assets, and mergers, every scenario depends on data and technology readiness. Banks that weigh outcomes as probabilities and keep investing in that readiness can absorb what follows.
Results are in from the US midterm elections on November 3, 2026. After a single night of voting returns, it’s already clear that banks will have to consider new policy realities. Pundits might call it a new mandate, but for the sell side, there’s another reality that politics news cycles miss. Priorities, policies, and regulations take time. For example, Dodd-Frank took over two years between the crisis and signing the legislation. Implementation deadlines for some pieces of it took another five years.
Even once legislation and regulation become codified, banks need a wide window to act on them. Changes must work their way through their business strategies, their internal policies and procedures, and their underlying technology. These windows can stretch over multiple quarters or years. That's longer than the two-year term of any individual Congress.
Political division between the legislative and executive branches of the federal government also remains a factor for the next two years. Legislative sea change will have to face the reality of presidential veto power's seawall.
Still, leadership teams at banks are actively considering scenarios. Four seem especially relevant in the conversations we've been having with our sell-side clients.
Basel III reform has been on the table in the US for several years. At the global level, the push has been to close loopholes in the calculation of risk-weighted assets (RWA). The approach in the US has contrasted with that, aiming to ease capital requirements and manage operational risk while maintaining safety.
The midterm elections may not change this momentum. Leaders at the helm of this initiative are primarily appointees at the Federal Reserve Board, the Federal Deposit Insurance Corporation (FDIC), and the Office of the Comptroller of the Currency (OCC). As such, even with statutory independence, they are nominally part of the executive branch.
What we do expect is more guidance on initiatives impacting RWA, the Liquidity Coverage Ratio, and the Supplementary Leverage Ratio in the early part of 2027. Policymakers have sought to recalibrate these levers to lighten the load on banks' day-to-day activity, such as lending. These efforts sit alongside the ongoing push to deliver mortgages to a wider population and reduce mortgage costs.
Legislative pressure may also push the pendulum back to more stringent consumer protections. For example, frequently discussed initiatives to cap credit card interest rates will likely gain new momentum.
These regulatory moves come together by impacting bank profitability and providing the critical resources needed to fund technology initiatives. Technology and data infrastructure at banks becomes less modern by the day. Modernization goes hand in hand with the ability to meet the continuous sea swell of regulatory change. Underinvestment puts your ability to push through big agendas at risk.
Questions directly or indirectly related to AI already play a role in the political climate around questions like employment and data centers. With AI at the center of banking and capital markets transformation, Tuesday's results strengthened guardrails on AI development. Regulations on the development and deployment of AI will likely increase.
Agents will still be an important part of banks and capital markets development, but the expected ROI on that development will be impacted. Political wins don't change the fact that success depends on high-quality data. They may, however, change the economics of what it takes to drive AI adoption and set banks on the path to transformation. CDOs and CTOs should take that into account.
The train has left the station on deployment of crypto and digital assets. Digital assets have proponents on both sides of the aisle, with a real appetite for both talking points and real progress. This is very likely to mean louder voices from Washington on the continued development of these tech-focused financial world initiatives.
But any of the groundswell depends on banks' ability to implement. Crypto presents unique tech challenges, from blockchain-driven real-time settlements to the complexities of crypto wallets and asset accounting. To support coin trading and perpetual futures, banks need to reassess their middle- and back-office systems, ensuring their tech stacks are ready for seamless integration of this evolving asset class.
In addition, digitizing assets requires real-time capabilities for ingesting trades, creating positions, monitoring risk, funding bank balance sheets, and more. It raises the bar on operational oversight and tech stack scrutiny.
The period between January and November 2026 saw hundreds of mergers among banks, credit unions, and bank holding companies. Scale still matters. But the pressure to consolidate faces political pressure, too. Tech-driven banking entities are adding more fuel to that fire. The open political question is around the factors that enable consolidation. It's still likely to occur, but the considerations may intensify, and the process for approving transactions may slow down.
In that environment, banks can't afford to overlook tech readiness. Acquisitions can be messy. Consolidating multiple operating systems is a costly and time-consuming endeavor. An integration team can deliver an early win on data conversion, one of the first tests of any merger, by using a purpose-built data framework and automated pipelines that move and reshape both firms’ data quickly and cheaply. This concept circles back to regulatory approval by creating a faster path that survives in-depth review.
Shifting attitudes and policy change are an inherent part of politics. Predicting or betting on an exact policy outcome in the wake of a midterm election can quickly result in surprises. However, one concept sits both above and below political change: readiness.
Banks transform on multi-year timelines that go beyond fluctuations in the political climate. And those efforts sit on a foundation of technology. The best approach after an election is to think it through in terms of scenarios and probabilities without losing sense of the longer-term priorities.
