Friday produced a rebound, not a resolution. The S&P 500 rose 0.43% to 7,674.10, the Nasdaq gained 0.43% to 26,179.37, and the Dow advanced 0.99% to 53,280.14. Yet the S&P 500 and Nasdaq still snapped three-week winning streaks and the Dow posted a second consecutive weekly decline. The week therefore ends with equities near their highs but with the market’s principal constraint more visible than it was five sessions ago: long-duration capital has become more expensive, and neither Treasury buybacks nor strong corporate earnings have yet neutralized that fact.

Friday’s macro data strengthened the growth side of that tension. S&P Global’s flash services PMI rose to 56.8, the strongest reading since December 2024, lifting the composite index to 56.0, its highest since April 2022. Manufacturing slowed to 53.2 as inventory accumulation faded and Iran-war supply disruptions persisted. The survey points toward third-quarter growth approaching a 3% annualized pace—hardly the backdrop from which a rapid collapse in long yields naturally follows.

The bond market responded accordingly. The 2-year Treasury yield rose about 5 basis points to 4.236%, the 10-year traded near 4.73%, and the 30-year near 5.27%. Treasury Secretary Scott Bessent’s willingness to expand long-bond repurchases has established an official sensitivity to market stress, but Friday reinforced the distinction between improving liquidity and changing the underlying price of duration.

Oil supplied the second constraint. Brent and WTI rose for a sixth consecutive session as Washington threatened sanctions on Iran’s trading partners and hopes for a normalization of Strait of Hormuz flows remained limited. Brent gained more than 6% for the week and WTI more than 5%. The market therefore enters the weekend with growth firmer than expected, energy inflation still active and the long end still demanding a substantial premium.
