US Regional Bank SRTs: M&A Accelerant or Repellent?

For a U.S. regional bank, attempting to use an SRT as an intentional pre-merger tool introduces a fundamental balance-sheet trap: severe post-merger structural rigidity. Unlike a one-off asset sale, an SRT is a highly complex, long-term credit arrangement that binds the issuer to an ongoing premium schedule such as the SOFR-linked coupons seen in the U.S. market. 

According to Matthew Bisanz, bank regulatory and derivatives partner at Mayer Brown, executing an SRT to artificially optimize a balance sheet ahead of a transaction ultimately binds the post-closing management team to a rigid and potentially costly financial strategy. 

"While such structures may enhance a bank's capital ratio," Bisanz notes, "they simultaneously impose a persistent interest expense on the merged entity. This effectively anchors the combined institution to a legacy SRT strategy, irrespective of whether it aligns with their broader post-closing objectives."
