MacroVoices #449 Harley Bassman: The Magic of Mortgages
Harley Bassman argues that mortgage-backed securities (MBS) are currently the best risk-adjusted investment in the bond market, particularly newly issued higher-coupon bonds trading near par. He believes the bond market has found its trading range around current levels and sees MBS as an attractive way to sell volatility through embedded call options.
Summary
Harley Bassman, convexity maven at Simplify Asset Management, presents a compelling case for mortgage-backed securities as the optimal bond investment in the current environment. He explains that MBS represent the second largest asset class in the bond market after Treasuries, yet retail investors rarely trade them directly due to their complexity involving monthly principal repayments, reinvestment risk, and tax complications. Instead, they access MBS through ETFs and mutual funds. Bassman's core thesis centers on the embedded optionality in mortgage bonds - when purchasing MBS, investors are essentially doing a buy-write strategy, selling call options to borrowers who can refinance. The recent inverted yield curve and high interest rate volatility have made these embedded options extremely valuable, causing mortgage spreads to widen from the historical 75 basis points over Treasuries to 125-170 basis points. He argues this presents an exceptional opportunity, particularly in newly issued mortgage bonds with 5-5.5% coupons trading near par, rather than the legacy low-coupon bonds that dominate mortgage indices. Bassman believes bonds have found their range, with the 10-year likely trading between 3.5-4.5% as the Fed targets a 2.5% funds rate in a world of persistent inflation driven by boomer retirements and millennial household formation. His strategy involves actively managing a portfolio of current-coupon mortgage bonds, keeping them between 97-101 price levels to maximize the value of embedded optionality. He launched an ETF (MTBA) to implement this strategy, made possible by recent SEC rule changes allowing derivatives in ETFs. Bassman dismisses credit concerns about agency MBS, noting they require high FICO scores and have government backing, making default risk negligible.

Key Insights
- Bassman argues that mortgage-backed securities are currently the best risk-adjusted investment in the bond market, trading at 125 basis points over Treasuries compared to investment grade credit at only 53 basis points
- He contends that newly issued mortgage bonds with 5-5.5% coupons are superior to legacy low-coupon bonds in mortgage indices because they offer larger embedded option premiums
- Bassman claims the inverted yield curve has artificially inflated the value of embedded call options in mortgage bonds, creating a pricing distortion that benefits buyers
- He believes the bond market has found its range with 10-year yields likely staying between 3.5-4.5% as economic fundamentals normalize around Fed targets
- Bassman argues that demographic trends - boomer retirements reducing labor supply and delayed millennial household formation creating demand surges - will keep inflation persistently above the Fed's 2% target
- He dismisses credit risk concerns about agency mortgage-backed securities, noting they require FICO scores above 720 and have effective government guarantees through Fannie, Freddie, and Ginnie Mae
- Bassman explains that recent SEC rule changes allowing derivatives in ETFs enabled him to create the first ETF focused exclusively on current-coupon mortgage bonds
- He advocates for selling interest rate volatility through mortgage bonds rather than taking duration or credit risk, arguing that implied volatility is extremely high relative to realized volatility in current market conditions

Daniel Lacalle argues that governments have exceeded the three limits (economic, fiscal, and inflationary) that maintain currency credibility, threatening the U.S. dollar's reserve currency status.

Michael Howell discusses global liquidity cycles and their impact on asset markets, arguing that the liquidity peak in late 2025 has begun rolling over and will likely bottom in mid-to-late 2027. He contends that gold has likely bottomed and should rally significantly due to Chinese monetary expansion and Western debt monetization, while warning that equities face headwinds as bond yields rise and the Fed may need to tighten despite political pressure.

Viktor Shvets discusses the paradox of disinflation as the dominant long-term trend while near-term inflationary spikes persist from policy decisions, the deterioration of the Federal Reserve's independence and cohesion under Chair Kevin Warsh, escalating geopolitical conflicts with no clear resolution, and the K-shaped economy driven by AI-induced wealth concentration that is fueling dangerous levels of political polarization.
