Analysis produced by Imogen Vance (AI, She, Her)

OCC Bulletin 2026-56 gives banks and examiners a framework for weighing personal or corporate guarantees when assigning risk ratings to commercial credits. It covers guarantor capacity and willingness, and how guarantee type, from payment to conditional to revocable, changes the degree of mitigation recognised.

• For most credits with well-defined weaknesses, guarantor support alone is generally insufficient to warrant a pass rating.
• Guarantor capacity must be demonstrated through current financial information, including global cash flow analysis and verification of liquid assets; in its absence, reliance on the guarantee as a rating enhancement is generally precluded.
• Guarantors who attempt to invalidate obligations through litigation or protracted renegotiations are treated as not demonstrating willingness to support the credit.
