In 2008, an imminent collapse of the banking system consumed Congress before lawmakers delivered a bailout. Three years later, a debt limit crisis enveloped Washington and led to a series of spending cuts after a dangerous brush with default and a first-ever downgrade in the nation’s credit rating. Now unease about the banking system’s stability and a stalemate over raising the debt limit are engulfing the capital simultaneously, ratcheting up an already high level of financial anxiety as two economic challenges Congress has experienced before become intertwined, the New York Times reported. “The stakes are exceptionally high when you are dealing with what amounts to a one-two punch of economic peril,” said Senator Ron Wyden, Democrat of Oregon and chairman of the Senate Finance Committee. “The messages that you send to the economy and the public with respect to banking and the full faith and credit of the United States — it doesn’t get more consequential than that.” Republicans and Democrats acknowledge it is a scary case of déjà vu times two. But they diverge sharply on how recent bank failures — and uncertainty over how Congress should respond to them, if at all — will influence the debt limit fight later this summer.
