Mortgage Rate Spread Mystery
- Mortgage rates significantly exceed treasury yields, currently by around 3%.
- This spread, the highest on record, raises questions about the mechanics of the mortgage market.
Unique Market Dynamics
- The current mortgage market situation is unique because it isn't driven by fear of defaults or falling house prices.
- Instead, it stems from a rapid shift from short-term to long-term mortgage-backed securities (MBS) due to rising rates and other factors.
MBS as Covered Calls
- Mortgage-backed securities (MBS) resemble covered calls, offering limited upside and greater downside risk.
- This makes them less appealing during rising rate environments when bond prices fall.
