The S&P 500 ground out its eighth consecutive weekly gain — the longest winning streak since 2023 — and the Dow closed at a fresh record after a +294-point Friday. It was a genuine tug-of-war: stocks sold off early as the 30-year Treasury yield punched above 5.19%, its highest since 2007, and the 10-year hit a one-year high near 4.61%. Sentiment then turned as President Trump paused imminent strikes on Iran to allow negotiations, pulling crude back below $100 and steadying rates into the close. Nvidia's blowout print — $81.6B revenue and an $80B buyback — drew a strangely muted reaction, a recurring tell that AI expectations have outrun even extraordinary delivery. Weekly tallies: S&P 500 +0.8%, Nasdaq +2.1%, Dow +0.4%.

This was a week defined less by a single catalyst than by two opposing forces clearing the same tape. On one side, the long end of the Treasury curve broke to levels not seen in nearly two decades, repricing the discount rate for every risk asset and hitting long-duration technology hardest. On the other, a credible path toward an end to the Iran war emerged, collapsing the geopolitical risk premium embedded in oil and pulling capital back into growth assets. The market chose, narrowly, to lean into the thaw — but it did so with the bond market flashing an unambiguous warning.
Minutes from the April 28–29 FOMC meeting, released May 20, confirmed a decisive hawkish turn. A majority of participants signaled that some policy firming would likely become appropriate if inflation continued to run persistently above 2%; many wanted the easing-bias language struck from the statement entirely. The vast majority flagged an increased risk that inflation takes longer to return to target than previously expected. The policy band holds at 3.50–3.75%, and a 2026 cut is no longer in the curve.
The story of the week. The 30-year yield topped 5.19% on May 19, its highest since before the 2008 financial crisis, with the 20-year near 5.15%. The 10-year hit a one-year high around 4.61% on Monday before steadying as oil fell. Two firm inflation reports the prior week, plus hawkish minutes, drove a bear-steepening that punished the most expensive equity cohort — the S&P tech sector saw intraday drawdowns above 2.3% early in the week.
The hard data held up. April retail sales rose +0.5% m/m to $757.1B, up +4.9% YoY, a third straight month of gains led by nonstore retail (+11.1% YoY). April housing starts, however, slipped −2.8% m/m to a 1.465M annualized rate, with single-family starts down 9% — clear evidence that 5%-plus mortgage-adjacent financing costs are throttling homebuilding even as the broader consumer keeps spending.
The pivotal shift: President Trump paused imminent strikes on Iran early in the week to allow negotiations, and Secretary of State Rubio cited “good signs” of a deal by Thursday. WTI fell more than 7% on the week and Brent near 5%, both back below $100. Sticking points remain — Iran's enriched-uranium stockpile and tolls on the Strait of Hormuz. Bitcoin firmed toward ~$80,000 as the risk premium drained; gold held near $4,700 as real yields capped the bid.
Technology drove the Nasdaq's market-leading +2.1% week despite being ground zero for the yield shock. Early in the week the S&P tech sector posted intraday losses above 2.3% as the long-end break lifted the discount rate on long-duration cash flows; the sector then recovered as oil fell and rates steadied. Beneath the index, the AI infrastructure complex remained the cleanest source of momentum — Hut 8 surged on a $9.8B compute-capacity agreement, and power-and-cooling names continued to attract capital as the buildout's second-order beneficiaries.
Nvidia's May 20 print was an outright blowout: revenue of $81.6B (~+85% YoY) versus $78.9B consensus, net income of $58.3B against a $42.9B estimate, data-center revenue nearly doubling year-over-year, and an $80B buyback. CEO Jensen Huang declared demand had “gone parabolic” as agentic AI scales. Yet shares slipped ~1.5% after-hours — the third straight muted-to-negative reaction to a beat, evidence that expectations have outrun even extraordinary delivery. AMD committed $10B+ to Taiwan AI investments, reinforcing a hyperscaler capex pool now estimated near $725B+ for 2026.
The Iran de-escalation cut both ways for defense. The primes have run hard on the war bid — RTX is up roughly 40% YTD on a $251B backlog, and Lockheed Martin carries a record $179B backlog — so a credible path to a ceasefire trimmed some of that premium and pulled names off recent highs. The structural story is intact: the U.S. Army is consolidating ~$20B of Anduril contracts and roughly $10B of Palantir work into single enterprise agreements, a decisive vote for software-defined defense. Palantir posted 104% U.S. revenue growth and lifted FY26 guidance to 71%, though its valuation remains extreme.
Biotech's recovery rolled on, with the equal-weighted XBI showing a trailing-12-month total return near +72% as a wave of gene-editing and oncology approvals re-rated the group. The FDA cleared Enhertu in the neoadjuvant and adjuvant settings for HER2-positive early breast cancer on May 16, and expanded the Vyvgart label to all serotypes of generalized myasthenia gravis. Not every catalyst landed: the FDA extended its review of Leqembi IQLIK by three months to August 24, a reminder that event risk runs in both directions. The sector remains a source of idiosyncratic alpha largely uncorrelated to the rate shock.

U.S. markets are closed Monday, May 25 for Memorial Day, compressing the week. The marquee release is April PCE — the Fed's preferred inflation gauge — later in the week; a hot core print would re-anchor the long end and undo Friday's relief, while an in-line read keeps the de-escalation rally intact. Watch every Iran-negotiation headline: a confirmed framework would extend the oil decline and the risk-on bid, while a breakdown over Hormuz or uranium would snap crude higher and re-stress yields.
A lighter earnings tape after Nvidia clears the calendar. Focus shifts to the read-through from this week's retail bellwethers and to AI-infrastructure follow-on (data-center power, cooling, memory). On the biotech side, the rescheduled Leqembi IQLIK timeline and the broader FDA approval cadence keep the group catalyst-rich. Defense investors will watch for any formal ceasefire language, which would likely keep pressure on the war-premium portion of the primes' recent move.
