After SVB, the biggest bond rally since 1987

The collapse of Silicon Valley Bank detonated an institutional panic across global capital markets, triggering the most violent flight-to-safety rally in sovereign debt since the Black Monday crash of October 1987. In a dizzying three-day sequence, the two-year US Treasury yield plunged by more than 100 basis points, collapsing from above 5.07 per cent to below 4.00 per cent as fixed-income algorithms frantically priced out future rate hikes and priced in aggressive emergency easing. Over the weekend of 12 March, the Federal Reserve, the Treasury, and the FDIC launched an unprecedented systemic risk exception, guaranteeing all uninsured deposits at SVB and Signature Bank while creating the Bank Term Funding Program (BTFP) to stem the bleeding.

The BTFP was an audacious operational construct: it allowed depository institutions to pledge US Treasuries and agency mortgage-backed securities as collateral for one-year central bank advances, valued not at prevailing market prices, but at par.

The Par Arbitrage

By valuing underwater paper at 100 cents on the dollar, the Federal Reserve single-handedly neutralized the $620 billion unrealised loss problem that threatened regional bank solvency.

Banks no longer had to fear fire-selling securities into a depressed market to meet deposit outflows; they could simply hand the discounted paper to the Fed and receive 100 cents in newly minted reserves. The facility was an emergency liquidity bridge designed to halt a nationwide run on the regional banking sector.

The Monetary Contradiction

Yet the policy contradiction at the heart of this intervention is breathtaking. For twelve months, the Fed had been shrinking its balance sheet and hiking rates to tighten financial conditions and destroy demand.

In a single weekend, it established an open-ended facility that injects emergency central bank credit directly into the banking plumbing. The epic bond rally following SVB’s demise marks the moment where the financial stability mandate forcefully collided with the inflation mandate, forcing the Fed to construct an emergency liquidity backstop to prevent its own tightening cycle from liquidating the banking system.
