What if insolvent US multiemployer pensions overwhelm the PBGC?
A wave of multiemployer plan insolvencies overwhelming the PBGC is a slow-burn fiscal-backstop story — it pressures HY credit modestly and invites a federal bailout debate, but the broad crypto/equity cascade overstates the immediate spillover. Rhymes with the 2014 Multiemployer Pension Reform Act and the 2021 ARPA pension bailout, both of which addressed the gap legislatively without market crisis. The transmission is the PBGC guarantee and ultimately the federal balance sheet; the forward angle is that the catalyst is congressional action, not the insolvency itself.
