On September 15, 2008, Lehman Brothers filed for the largest bankruptcy in American history. Within hours, money market funds broke the dollar, interbank lending froze, and the machinery of global credit — the invisible infrastructure beneath every mortgage, payroll, and trade transaction on earth — came within days of complete seizure. What followed was not a recession. It was a controlled demolition of financial assumptions that had governed Western economies for three decades. This book reconstructs the 2008 crisis as both an institutional failure and a political emergency. It traces the decade of deregulation, synthetic instrument proliferation, and ratings agency capture that made collapse inevitable — and the frantic weekend negotiations, emergency Fed interventions, and congressional battles that determined which institutions would be saved and which would not. It examines who bore the cost of rescue: not the banks whose executives retained bonuses, but the homeowners, pensioners, and municipal governments left outside the perimeter of bailout. Drawing on Federal Reserve transcripts, Treasury Department records, congressional hearings, and testimony from regulators and victims alike, this is a rigorous account of how the global financial system failed, who rebuilt it, and why the structural conditions that produced the Lehman moment were never fully dismantled.
