Talk Your Book: Betting on Duration

Episode Summary

Executive Summary: The episode centers on the rapid normalization of the Treasury yield curve and what it means for fixed-income investors. Michael and Ben speak with Alex Morris of FM Investments about why long rates rose so sharply, why bond ETFs have drawn attention, and how single-maturity Treasury ETFs differ from range-based funds. The discussion emphasizes that higher yields now create real opportunity across the curve, with different products suited to different goals: liquidity, safety, yield locking, or duration exposure.

Main Topics: Yield curve normalization and long-end repricing (Priority: 5/5): The hosts and guest discuss how an inverted curve has begun to uninvert not because the Fed cut rates, but because long-term Treasury yields rose quickly, reflecting stronger growth expectations and a reset of market assumptions. Why long rates moved higher so fast (Priority: 5/5): Alex Morris argues the move reflects multiple factors: a long period of market complacency about the long end, the Bank of Japan reducing its support for JGB yields, and traders finally accepting that the Fed would not quickly reverse course. Treasury ETF design: single maturity vs multi-bond funds (Priority: 5/5): The conversation compares direct-maturity ETFs such as U2/U10 with range-based Treasury funds. The guest argues single-maturity ETFs better match investor intent by giving precise duration exposure, better liquidity, and clearer yield expectations. Yield, duration, and convexity now matter again (Priority: 4/5): Participants note that investors are once again forced to think carefully about duration, reinvestment risk, and convexity because short-term cash-like returns no longer dominate every decision and fixed income offers meaningful tradeoffs. Where the best opportunities are on the curve (Priority: 4/5): Morris says the sweet spot depends on the objective: short bills for safety and minimal volatility, longer maturities for more upside if rates fall, and the 5- to 10-year area for a balance of liquidity and price sensitivity. Investor behavior and the psychology of round numbers (Priority: 3/5): The episode highlights how investors react to familiar thresholds like 5% on the 10-year Treasury, suggesting that psychologically important levels can attract buyers even when small basis-point differences seem trivial.

Key Arguments: The long end of the Treasury curve rose because markets stopped believing the Fed would quickly cut rates and because foreign central bank actions, especially the Bank of Japan’s shift, removed an artificial cap on global yields. The inversion of the yield curve normalized through long-rate increases rather than Fed easing, making this cycle different from common historical expectations. TLT’s asset growth during a drawdown may reflect short-selling activity and trading interest, but the product’s structure can produce mismatched investor expectations because it holds low-coupon long bonds. Single-maturity Treasury ETFs are more precise than range-based products because they target one maturity bucket, avoid unintended duration drift, and better align with investor goals. Buying a Treasury ETF does not exactly replicate locking in a bond’s nominal yield because the ETF’s yield changes as holdings roll and because capital appreciation/losses can offset changes in market rates. The short end remains attractive for safety and low volatility, but the 5-year to 10-year range offers more meaningful upside if rates fall, while still being liquid enough for institutional and retail use. Bond investors are finally getting paid again, so fixed income can once again serve as a real asset allocation choice rather than a placeholder for cash. The bond market has been too optimistic about disinflation and policy pivots, partly because large institutional players move slowly and consensus takes time to adjust. Higher-for-longer is now the consensus because the Fed has been consistent in its communication and the economy has proven resilient. Treasury supply dynamics matter: more issuance at the long end could pressure yields, but technical and psychological levels like 5% may still act as resistance.

Data Points: Yield curve inversion streak: Second-longest since 2007 - Used to describe how long the Treasury curve remained inverted before beginning to normalize. 10-year Treasury move: About 5x in the last 12 months - Alex Morris describes the rapid rise in yields on a relative basis. TLT short interest: About 12% of open interest - As of mid-to-late October, indicating notable short-selling activity in the ETF. TLT drawdown: Deeper than the S&P 500 during the dot-com bubble - Used to highlight the severity of the bond ETF’s decline. U.S. Treasury bill share of issuance: About 25% - The Treasury is currently financing roughly one in four bonds as bills. Treasury target bill share: About 20% - The Treasury is trying to reduce bill issuance to one in five. 10-year yield threshold: 5% - The guest says buyers often step in whenever the 10-year touches 5%. TLT yield vs realized coupon: 4.7% to 4.9% yield versus about 3.5% or less realized in the ETF - Explains why ETF holders may not receive the headline yield they expect due to embedded low-coupon bonds. U.S. 30-year long-term growth expectation: 400 to 500 basis points - Guest argues this is a more reasonable long-run growth/return expectation than 100 bps. Potential 10-year price loss if yields rise 100 bps: 2.6% over the next 12 months - Scenario analysis discussed for U10/10-year exposure. Potential 2-year return if the Fed cuts: 7% to 8% in six months - Illustrates upside asymmetry in the short end if rates fall. Argentina lending rate: 118% - Used as a comparison to show how different sovereign rate environments can be. U10 holding period tax treatment: 365 days - After one year, capital gains in the ETF structure can convert from short-term to long-term treatment. Asset levels in T-bills ETF: $2.5 billion - Assets under management cited for the three-month T-bill product. Asset levels in 6-month bill ETF: $500 million - Assets under management cited for the six-month bill product.

Pivotal Quotes: "There’s a lot of ways to win, right? Like there’s a lot of ways that you can successfully implement an approach to fixed income." — Alex Morris: Explaining that investors should not think about the curve in only one directional bet, but in terms of goals and tradeoffs. "What you see is exactly what you get with the US benchmark series. Not always the case with the multi-bonds." — Alex Morris: Contrasting single-maturity Treasury ETFs with range-based Treasury funds. "We spent decades trying to build a resilient economy. We got one." — Alex Morris: Describing why the Fed is likely to keep rates higher for longer rather than ease quickly.

Implications: Listeners should view fixed income as a genuine opportunity set again, not just a cash substitute. The best Treasury exposure now depends on whether the goal is safety, yield, or duration upside, and ETF structure matters more than many investors realize.
