Global Cross-Asset Daily

AI leadership continues to drive index returns higher even as breadth narrows further. The S&P 500 and Nasdaq Composite both closed at fresh all-time highs on Tuesday (7,519 and 26,656 respectively), delivering YTD returns of c.9.8% and c.14.7%. But the gains remain concentrated: Technology (XLK +2.63%) was the only sector to deliver a notable contribution on the day, while Energy (XLE -2.76%) was the worst performer as Brent settled at $98.63 (-11.37% on the week). We expect the rally to extend in the near term as crude continues its peace-deal unwind and Treasury yields rally across the curve — the 10Y is down 17 bp on the week to 4.50% and the 30Y is down 15 bp to 5.03%. Under such a scenario, duration-sensitive assets and lower-volatility defensives stand to benefit alongside the chip leadership. Crypto, however, has notably opted out — BTC -1.26% on a record-S&P session — and this absence of the speculative-growth bid reinforces our view that the current rally is fundamental rather than positioning-driven. The week's two binary risk events are both on Thursday: US Core PCE and the ECB press conference.

§ 01 — Equities · United States

The post-holiday session delivered a chip-led record on the broad index — and a Dow lag worth attention. The S&P 500 (+0.62%) and the Nasdaq Composite (+1.19%) both closed at fresh all-time highs of 7,519 and 26,656 respectively; the Russell 2000 added +1.79% to take its weekly gain to c.6.3%. Case in point: the Dow's -0.23% drag was driven almost entirely by Energy and Consumer Staples — its two heaviest historical sector weights — rather than by any breakdown in broad index participation. Year-to-date, the gap inside the US complex now reads Russell 2000 +17.7%, Nasdaq Composite +14.7%, S&P 500 +9.8%, Dow +5.0%. Small-caps have recovered c.two-thirds of their relative-strength gap against the broad index in five weeks. We think the operative question for Thursday's Core PCE is whether duration-friendly small-caps can hold their leadership against any inflation surprise — under a hot print, momentum-style rotation back into mega-cap quality is the more likely outcome.

§ 02 — S&P 500 Sector Map

Tuesday 26 May · sorted best to worst

Sector breadth on Tuesday was 6-up / 5-down, with Technology leading and Energy lagging — a clean factor read. Cyclicals with low oil sensitivity (Technology XLK +2.63%, Industrials XLI +1.47%, Materials XLB +1.39%) all rallied; defensives and oil-linked sectors (Consumer Staples XLP -1.38%, Energy XLE -2.76%, Health Care XLV -0.92%) sold off. We see this as evidence that the day's bid was driven by lower-crude / lower-yields disinflation positioning rather than by broad cyclical re-acceleration. Year-to-date, leadership remains with Energy (+29.4%) and Technology (+28.6%) — but Energy's lead is built on prior-quarter gains rather than recent flow, and we expect that gap to narrow further if crude continues to consolidate below $100/bbl. Financials (-5.3%) and Health Care (-4.1%) remain the only red sectors on the year; Consumer Discretionary has just recovered to flat (+0.03%).

Asian semiconductor leadership remains the structural story; continental Europe consolidates and Greater China continues to underperform. The KOSPI extended its run with +2.54% on Tuesday and is now +90.96% YTD — the world's clear standout. Continental Europe digested Monday's peace-deal pop with a modest pullback (DAX -0.61%, CAC -1.03%, STOXX 600 +0.46% on the day); the FTSE 100 returned from Bank Holiday at +0.24%. On the week, the global leaderboard reads KOSPI +10.7%, TAIEX +8.3%, Nikkei +7.3% — Asian semis are doing the work of the rally. China underperformed once again: Hang Seng was flat both on the day and on the week; Shanghai Composite -0.17% and -0.58%. We think the AI-supply-chain bid will remain concentrated in energy-importing, manufacturing-heavy Asia rather than re-rotating into Greater China in the near term, given the persistent regulatory overhang. STI -0.82% on REIT-sector profit-taking.

§ 04 — US Treasuries

3.5% 4.0% 4.5% 5.0% 6M 2Y 5Y 10Y 20Y 30Y

The curve rallied across all tenors on Tuesday — but the day-over-day and week-over-week moves tell two different stories. On the day, the move was bull-steepening: 2Y -12 bp, 5Y -8 bp, 10Y -6 bp, 30Y -4 bp — the front-end fell hardest, consistent with a modest re-pricing of Fed-cut expectations. On the week, the pattern flipped to bull-flattening: 30Y -15 bp, 10Y -17 bp, 2Y -12 bp, 5Y -13 bp — driven primarily by crude's collapse compressing inflation breakevens. 2s10s is now 49 bp (vs 54 bp last week); 2s30s is 102 bp (vs 105 bp). Year-to-date the picture remains bear-flattening (2Y +54 bp dominates the move, 30Y only +19 bp) but the week's rally has narrowed that steepness materially. We now think the path of least resistance for the long end is another c.5-10 bp of compression if Thursday's Core PCE prints in line with the +0.3% MoM consensus. Under such a scenario, richly-valued long-duration assets stand to benefit further.

§ 05 — Credit Spreads

Source: FRED · ICE BofA OAS series · latest 22 May 2026 (Memorial Day Mon backfill, daily reading T-1 lag from this run's date)

Investment-grade and high-yield credit continue to tighten while CCC remains the only tier showing net stress. IG OAS dropped to 74 bp (-1 bp on the day, -5 bp YTD — the year's tightest); BBB sits at 93 bp (-8 bp YTD); broad HY tightened -4 bp on the day and -6 bp on the week to 274 bp. CCC at 939 bp was unchanged on the day and remains +54 bp YTD. We think the IG-to-CCC dispersion (c.59 bp wider than year-end) reflects a structural bifurcation that has survived every risk-on session of 2026: high-quality borrowers and broad equities agree on a benign macro path; the speculative end of the credit market does not. The dispersion will not compress materially until either the Fed signals cuts (re-rating CCC financing costs) or energy stays contained long enough to relieve energy-junk credits specifically. Under our base case of crude consolidating below $100/bbl, we expect CCC to tighten c.15-25 bp over the coming weeks.

§ 06 — Digital Assets

Crypto continues to opt out of the AI-equity bid — and we see this as an increasingly persistent regime signal. BTC closed at $75,625 (-1.26% on the day, -13.57% YTD) on the same session that the S&P 500 printed an all-time high; ETH at $2,068 (-1.04%, -30.31% YTD); SOL at $83.60 (-0.47%, -32.82% YTD). Historically, BTC has traded as a high-beta Nasdaq proxy — but that correlation has decisively broken down in 2026. We think capital seeking AI exposure is being channelled into chip equities and Asian-tech rather than into digital assets, and we expect this dispersion to persist while AI infrastructure spending remains the dominant institutional theme. BTC remains c.US$50,000 below its October 2025 all-time high; the trend has not broken on a technical basis, but the relative-strength deterioration against equities has accelerated all year.

§ 07 — Metals & Energy

Brent settled at $98.63 on Tuesday (-0.95% on the day, -11.37% on the week); WTI at $92.35. The Iran-deal unwind continues to flow into crude even as headline news quiets, and the multi-day decline confirms that the spring premium is being structurally re-rated rather than headline-traded. Under our base-case scenario of a near-term US-Iran resolution and gradual normalisation of Strait of Hormuz traffic, we now expect Brent to average c.US$85-90/bbl through 2H26. Year-to-date, crude remains the standout commodity move of the year: Brent +62.1%, WTI +60.8%. Gold (-0.06% on the day, +3.7% YTD) and silver (+0.4%, +8.9% YTD) consolidated as real-yield pressure eased; copper (+0.8%, +13.5% YTD) holds the AI-build-out bid. Natural gas was the day's surprise mover at +3.5% to $3.00 on US Gulf weather; at -18.7% YTD it remains the only major commodity flat-to-negative on the year.

§ 08 — Economic Calendar

Two binary risk events frame this week, both falling on Thursday. US Core PCE prints at 08:30 ET — consensus is +0.3% MoM, a confirmation of the Fed's preferred inflation gauge. An in-line print keeps the long-end rally intact and validates the Fed-on-hold narrative; a +0.4% surprise would reverse the past two weeks of duration tightening. Wednesday's ECB press conference is the secondary set-piece. With German and French May CPI flash on Friday (+2.9% and +2.6% consensus respectively), the ECB has sufficient cover to signal data-dependence without committing to a direction. We are also watching the Asian tail closely: China NBS Manufacturing PMI (Sunday) and Caixin PMI (Monday) will frame next week's open, while US JOLTs and ISM Services close the loop next Tuesday — under our base case of an in-line Core PCE, the labour-market data are the next inflection.

§ 09 — Macro Themes

1 · AI chip leadership is the de facto US index at present. Barron's and CNBC both led Tuesday with chip-stock optimism as the primary driver of the S&P/Nasdaq record; Technology (XLK +2.63%) delivered the broadest sector gain on the day, while semi-leveraged Asia (KOSPI and TAIEX) extended its YTD lead. With margin debt at c.US$1.3 trillion (per Seeking Alpha) and Berkshire's cash hoard at c.60% of portfolio value, institutional positioning is bifurcated between full-throttle AI exposure and full-defensive cash. We see this dispersion as evidence that the AI trade is not yet a positioning-crowded one.

2 · Iran-deal pricing has shifted from headline-driven to structural. Tuesday's Brent -0.95% and WTI +0.83% (intraday volatility) confirm the supply-side reset is a multi-day re-rating rather than single-headline action. Quantum Strategy's David Roche has cautioned that markets may be over-pricing peace odds; UN food economists (via 247WallSt) have flagged fertilizer-system fragility. We think the asymmetry on a break-down in talks is now larger than the asymmetry on a signing.

3 · The Warsh-Fed-on-hold narrative remains the prevailing read. ETF Trends flagged that recent data gives "little reason for an imminent rate cut"; Fox Business cited Hassett expecting inflation to fall as the Strait reopens. The front-end's -12 bp rally on Tuesday was a small re-pricing toward easier policy, not capitulation. We think the market is currently buying disinflation rather than Fed action — a path that Thursday's Core PCE will probe directly.

4 · The consumer-sentiment-versus-market-record divergence remains stark and warrants close attention. The Conference Board reading (May confidence 93.1 vs prior 93.8) and MarketWatch's coverage flagged the disconnect — Americans report worse-than-ever financial well-being even as US stocks make all-time highs. We see two competing interpretations: the bull camp reads the equity tape as forward-looking; the bear camp reads sentiment as a late-cycle signal. Historically, such divergences have preceded periods of higher equity volatility even when the macro backdrop remained supportive.

5 · The 30Y yield at 5.03% is attracting structural buyers. Investopedia and MarketWatch both ran "should I move into bonds" pieces this week — a retail-flow sentiment signal that real money may be following the institutional bid. The bond complex's behaviour this week (long-end -15 bp, IG -5 bp YTD tight) suggests this flow is already in motion. We expect rotational interest toward long-duration government and high-quality investment-grade credit to revive sooner than later, particularly under a benign Core PCE outcome.

§ 10 — Analysis & Nuances

Tuesday was a textbook "lower oil, lower yields, higher growth equities" cross-asset session — with one notable exception that warrants close attention. The S&P 500 printed a record on Nasdaq leadership; the curve rallied with the front-end leading; Brent stayed contained. Every component of the day-trade played out as the disinflation narrative would predict. The exception is crypto: BTC, ETH and SOL all closed lower on a record-S&P session, breaking the pre-2025 correlation pattern in which BTC traded as a high-beta NDX proxy. We see crypto's silence as the cleanest signal that the current rally is fundamental in nature rather than speculative — capital is flowing into chip equities and duration, not into the speculative-growth complex.

The yield-curve direction this week is more nuanced than the headline "curve rallied" framing suggests. The week-over-week story is bull-flattening (30Y -15 bp vs 2Y -12 bp), but Tuesday's intraday move was bull-steepening (front-end fell harder than the long end). Together, these tell us markets revised down both inflation and growth expectations on the week, but specifically priced more Fed-cut optionality on Tuesday. We expect Thursday's Core PCE to resolve which read holds: an in-line print confirms the disinflation-without-cuts path (long-end continues to lead); a soft print tilts toward earlier cuts (front-end leads); a hot print reverses both. Under our base case of an in-line outcome, the long end has clear room for another c.5-10 bp of compression.

The Asian semiconductor bid is structurally asymmetric — and we see this as the strongest sub-signal of the year. KOSPI is +91% YTD, TAIEX +50%, Nikkei +29% — all reflecting AI-supply-chain accumulation. Hang Seng at -0.12% YTD and Shanghai Composite at +4.5% YTD do not. The same regional theme has not powered Greater China at all, and we attribute this primarily to the persistent China tech regulatory overhang (Schwab Network flagged new AI rules on Tuesday). Under such a scenario, we expect Korea and Taiwan to inherit additional relative bid if Chinese regulation hardens further; conversely, any meaningful regulatory easing would likely rotate the next c.US$200B of Asian inflows back into Hang Seng. We are watching the daily H-share-versus-Korean delta as a leading indicator of capital flow direction.
