Episode notes
Swap Spreads, Not Basis Trade
- The basis trade initially suspected to cause Treasury market volatility showed no significant trading anomalies in futures volumes or prices.
- The real volatility was driven by the swap spread market unwinding, reflecting leverage in interest rate swap positions.
Why Swap Spreads Stay Negative
- Regulatory constraints limit banks' ability to own treasuries, keeping swap spreads negative.
- Insurance companies use interest rate swaps to manage duration gaps because buying treasuries outright is less balance sheet efficient.
Liquidity Constraints Amplified Volatility
- Joe Weisenthal stayed up late watching yield spikes on April 9th that reflected very low liquidity hours in Asia.
- Dealer constraints and regulatory limits reduced their capacity to absorb selling, amplifying price moves.
