DNB Research Finds Too-Big-to-Fail Funding Advantage Persists for Domestically Systemic Banks
A De Nederlandsche Bank working paper finds that the implicit too-big-to-fail (TBTF) funding subsidy is driven not by G-SIB designation but by a bank's size relative to its home sovereign's GDP, with banks exceeding roughly 50% of home-country GDP enjoying at least 30% lower credit spreads than comparable peers. For compliance and prudential risk teams, this suggests that resolution planning, capital add-ons, and supervisory stress testing frameworks tied strictly to G-SIB status may understate implicit bailout expectations for large domestic banks.
