500 Miles
Some numbers have a way of sticking in the mind. For Scottish rock duo The Proclaimers, it was a willingness to walk 500 miles; for the bond market, it is reaching a 5% yield on the 10-year Treasury note. That level has become a psychological landmark as investors weigh persistent inflation pressures against renewed demand for safety.
The forces that pushed the yield above 5.00% — inflation concerns, robust economic growth, fiscal largesse, and heavy fixed-income supply—remain intact. Last week, however, those underlying pressures took a backseat to concerns about tech valuations, wider credit spreads on AI issuers, and broader equity weakness. The resulting demand for Treasuries brought the yield back to that familiar landmark by Friday.
Oil prices and the 10-year Treasury yield also diverged last week. Earlier in the Iran conflict, rising oil prices reinforced inflation concerns and pushed the 10-year Treasury yield higher. This time, demand for Treasuries outweighed the inflation pressure; equity weakness and wider credit spreads shifted investors’ attention toward risk. Meanwhile, oil prices continued to rise as the war in the Middle East persisted, with crude and Brent reaching $102 and $115 per barrel, respectively (Figure 1).
Equity weakness and wider credit spreads tightened financial conditions without an additional rate increase from the Federal Reserve. The Bloomberg US Financial Conditions Index fell to 0.791 on Friday (Figure 2). This z-score-based index is centered around zero: Positive readings indicate looser-than-average conditions, while negative readings indicate tighter than average conditions. The still-positive reading indicates that conditions remain looser than average, even as recent developments removed some accommodation.
The tightening in financial conditions has delivered some of the restraint that might otherwise need to come from additional Fed rate increases. The distinction is between conditions becoming tighter and becoming outright restrictive. With the broader growth, inflation, and supply backdrop largely unchanged, it is too early to conclude that markets have done enough of the Fed’s work. Investors have nevertheless reduced their expectations for additional tightening. Markets largely expect no rate change at the October meeting, while expectations for a December hike have diminished. Figure 3 shows that the number of anticipated hikes for 2027 fell by one 25-basis-point increase, leaving two hikes priced in.
The Treasury rally improved the rate-lock opportunity for borrowers, but it has not produced an equivalent improvement in secondary-market execution. Ginnie Mae volumes are up, year over year, and DUS and Freddie Mac originations have remained productive. Until recently, origination activity was sufficient to keep business moving without building excessive balance-sheet exposure. Yet the recent rally encouraged borrowers to lock rates, increasing the flow of loans into the pipeline.
The bottleneck is now downstream in the tranched REMIC market, where wider investor spreads are working against the benefit of lower benchmark yields, particularly for buydown-heavy Ginnie Mae collateral. The popularity of buydowns and the preceding rapid rise in rates have complicated execution. Because months can pass between rate lock and security delivery, investors are receiving lower-coupon collateral locked under an earlier rate environment. It remains difficult to structure that collateral into tranches with yields that are competitive with current residential mortgage securities and corporate bonds.
The next test is whether stronger rate-lock activity can be matched by demand for the resulting securities. A sustained improvement in execution would require not just lower Treasury yields, but stabilization in investor spreads and better absorption of buydown-heavy collateral. The Treasury market has made the journey back to 5.00%, but mortgage investors may need to walk 500 miles more.
FROM THE DESK
Agency CMBS — Weakness was most pronounced in the buydown segment: Spreads on loans with note rates below 6% widened by 10 or more basis points, compared with five basis points for current coupons. The move was consistent with feedback from our New York meetings last week, where investors highlighted weak GNR (tranched REMIC) execution and the risk of further spread widening. Most of the week’s widening occurred towards the close, as higher yields available elsewhere in the market weighed on demand.
Municipals — AAA tax-exempt yields moved lower across the curve for a second consecutive week, led by a front-end rally of more than 20 basis points. Despite inflation concerns, geopolitical tensions in Iran and unrest in France supported a flight to quality and demand for municipal bonds. Even as rates declined, spreads on cash-collateralized and M-TEB issues tightened modestly. Investor demand remained robust, highlighted by a third straight week of mutual fund inflows exceeding $1 billion, including $756 million into high-yield municipal funds.
