The news: Rising Treasury yields are squeezing regional bank margins, but many lenders are offsetting the pressure by building fee-based businesses that mirror Wall Street banks, per Telis Demos in The Wall Street Journal. Last week, the two-year Treasury yield hit its highest level in over a year, reviving concerns about deposit costs. 

Zooming in: Regional banks’ strategy of relying less on traditional lending and more on fee-generating businesses like investment banking, merger and acquisition (M&A) advisory, and treasury-management services are paying off. Fee revenues at regional banks in the KBW Nasdaq Bank Index rose 12% in Q2 versus Q1, nearly matching megabanks’ 13%, according to Visible Alpha data cited by The Wall Street Journal. And noninterest revenue at regional banks was roughly half of net interest income in Q2 2026, up from about 40% in early 2023.

Bank executives say the shift is intentional. Truist is moving away from some consumer lending and toward commercial banking relationships that create opportunities to sell higher-margin services, including payments, capital raising, and M&A advisory. Meanwhile, KeyCorp says its M&A advisory pipeline is at a record high, reflecting a broader industry push to diversify revenue and grow through scale. Indeed, 60.6% of community bankers cite the inability to achieve economies of scale as a major driver of bank M&A, according to a 2025 Conference of State Bank Supervisors survey.

Implications for banks: Building fee-based income is a structural response to compressing margins. As companies increase capital spending tied to the AI buildout, banks that attach advisory and payments to commercial lending can earn more per dollar deployed. Some banks are building that cross-sell through partnerships instead of new capacity (e.g., U.S. Bank and Edward Jones’ cobranded checking and credit card offering for mass-affluent clients). Stacking fees onto interest income improves returns on equity, and commercial loans often require less regulatory capital than consumer loans, because they're frequently secured by financial collateral.

But competition is still intense. Regional banks are trying to win more business from midsize companies—but so are megabanks. Even if a regional bank provides a loan, that client could hire another bank for more lucrative services, like M&A advice or raising capital. If interest rates stay high, companies may also delay deals and fundraising, reducing opportunities for banks to earn those fees.

As a result, some regional banks are buying investment banks to quickly add fee-based businesses, while others are strengthening relationships with existing business clients in hopes of selling them additional services over time. Whether fee revenues continue growing at their recent pace will determine if investors view regional banks more like their Wall Street competitors.
