The week's dominant story was the Strait of Hormuz oscillating between hope and fear in real time. Trump signaled a deal was "largely negotiated" on May 25, two LNG tankers completed the first successful transits since February, and Brent crude collapsed to $94.50 in a single session. Then U.S. "self-defense" strikes in southern Iran on May 27 sent Brent back to $96.67, a +3.5% reversal. WTI crude finished the week down 10.86%, closing at $87.36, but that weekly figure masks intraday swings from a high of $99.43 to a low of $86.35. The net read: markets are pricing partial reopening, not full normalization.

The second-order story is what this energy volatility means for monetary policy. New Fed Chair Kevin Warsh has taken the helm of the Federal Reserve and markets have already moved: a 25bps hike is priced for January 2027, a complete reversal from the cuts that were expected before the West Asia conflict began. The ECB separately flagged a "unavoidable" June hike to fight 3.0% eurozone inflation, while the Bank of England sits in a more comfortable position after UK April CPI cooled to 2.8%. Three major central banks, three divergent postures, all shaped by the same energy shock.

The counterintuitive read: a week that opened with an oil crash ended with equities broadly higher. The Nikkei surged +4.2%, small-caps and Nasdaq both gained over +2.2%, and the 10-year Treasury yield fell 9 basis points to 4.45%. Risk assets are betting on de-escalation becoming durable even as military action continues. That is a fragile consensus, and the gap between market optimism and geopolitical reality remains the central risk for the weeks ahead.

This week's action was driven by one catalyst: Trump's signal that the Strait of Hormuz could reopen, followed immediately by U.S. strikes in southern Iran that reminded everyone the situation is not resolved. WTI crude swung from $99 to $86 and back to $87 in a single week, the most important price move for global macro positioning. The Nikkei surged 4.2% and EEM gained 3.94%, both repricing on cheaper energy imports and a softer dollar. U.S. equities also climbed, led by QQQ and IWM both up over 2.2%, with Micron's $1 trillion AI milestone adding fuel to the Nasdaq move. The Fed under Kevin Warsh is now pricing a January 2027 hike rather than 2026 cuts, so the rate environment has shifted hawkish even as this week's bond rally sent the 10-year yield down to 4.45%. European equities lagged badly, with DAX and FTSE both slightly negative, caught between ECB hike signaling and collapsing UK consumer demand.

The Nikkei 225 surged +4.2% this week, closing at 66,329 after Trump signaled the Hormuz deal is "largely negotiated" and two LNG tankers completed the first successful transits since February. Japan is structurally the most leveraged equity market to cheaper energy: it imports virtually all of its oil and LNG, so every dollar off the crude price directly expands corporate margins and reduces the trade deficit. The market is not yet pricing a full reopening. It is pricing a probability-weighted partial reopening. If negotiations advance, the Nikkei has further to run.

The setup has two tailwinds compounding. First, the 10-year U.S. Treasury fell 9bps this week, and a softer global rate environment historically supports Japanese export earnings and P/E expansion. Second, the yen weakened slightly despite the equity rally, which means Japanese exporters are getting a double benefit: lower input costs from cheaper energy and a competitive exchange rate. The risk to this trade is currency drag for unhedged holders of EWJ, but the equity beta to Hormuz resolution is strong enough to carry the position even with some yen headwind.

Confirms: Nikkei 225 holds above 65,000 and WTI crude stays below $92 into next week's session, confirming that markets are treating the Hormuz situation as structurally de-escalating rather than temporarily paused. Risk: A second confirmed U.S. military strike in Iran or a Hormuz transit blocked by Iran's navy snaps the energy-import narrative and triggers a sharp Nikkei reversal, likely back toward the 63,500 weekly low.

The Nikkei 225 was the week's standout, rallying +4.2% to close at 66,329 and briefly touching 66,505. The catalyst was direct: oil-dependent Japan is the largest beneficiary of any Hormuz reopening, and Trump's May 25 signal triggered an immediate re-rating of the country's energy import bill. The Nikkei's move was not about domestic fundamentals. It was a pure geopolitical options trade on cheaper energy. Emerging markets followed, with EEM up +3.94% to $68.60, also repricing on the same energy de-escalation logic plus a softening dollar.

In the U.S., the Russell 2000 and Nasdaq both gained +2.24-2.25%, outpacing the S&P 500's +1.49% and the Dow's +1.19%. Micron's +19.3% surge to a $1 trillion market cap on AI memory demand was the single biggest individual driver of Nasdaq outperformance. Small-caps benefiting from the 9bps drop in the 10-year yield tells a rate-sensitive domestic story running in parallel to the AI hardware story. Europe was the laggard: the Euro Stoxx 50 managed +1.08% but the CAC 40, DAX, and FTSE 100 all closed fractionally negative, dragged by ECB hike signaling and UK retail sales collapsing 1.3% in April. European equities are caught between an energy tailwind and a tightening headwind. That tension explains why they gave back early-week gains.

The USD Index fell 0.29% to 98.91, a mild move that nonetheless provided cover for EM and commodity currencies to breathe. The CHF gained +0.19% against the dollar and the EUR added +0.16%, consistent with the ECB's hawkish June hike signal pushing EUR/USD to 1.1659. Sterling slipped 0.18% despite BoE relief on CPI: UK retail sales falling 1.3% in April removed any near-term rate-hike premium from the pound. The AUD's marginal +0.09% gain is notable given the commodity volatility. It suggests AUD is being supported by broader EM risk appetite rather than the oil price itself.

The yen weakened 0.21% against the dollar, closing at 0.006279 JPY/USD, which is the counterintuitive move of the week. The Nikkei surged on Hormuz hopes, yet the yen did not strengthen alongside it. Japan's equity rally was driven by foreign capital chasing the energy-import-cost story, not by domestic monetary tightening expectations. For global investors holding EWJ unhedged, the currency drag partially offsets the equity gain. A hedged Japan position via a currency-hedged vehicle captures the full Nikkei move.

WTI crude fell 10.86% on the week, closing at $87.36 after printing a high of $99.43 and a low of $86.35. That is a $13 intraday range in a single week, driven entirely by the Hormuz open-close-reopen sequence. The May 25 LNG tanker transits drove the initial crash. The May 27 U.S. strikes in southern Iran pulled oil back. The net weekly decline reflects a market that has structurally repriced some risk premium out, but has not declared the crisis over. Natural gas was the week's overlooked mover: +9.67% to $3.29, touching $3.39 at the high. With LNG transit routes in focus, any supply disruption story in gas amplifies fast.

Gold held its ground at $4,560.50, up +0.91% for the week and within striking distance of the $4,591.80 weekly high. Gold is not selling off on the risk-on rally. That is significant. It suggests investors are maintaining macro hedges even as equities climb, consistent with the Warsh Fed hike pricing and ongoing Middle East uncertainty. Silver slipped 0.53% and underperformed gold, which typically happens when the industrial demand story weakens relative to the safe-haven story.

The econ_events fields for both past and upcoming weeks were empty in the data, so specific release surprises cannot be scored against consensus. What the news context makes clear is that the two most important data points of the week were not scheduled macro releases: the UK's April CPI print of 2.8% gave the BoE breathing room, while UK retail sales crashing 1.3% in April confirmed the UK consumer is under severe pressure. These two readings in combination tell a stagflation-lite story for the UK, where inflation is cooling but not because demand is healthy. It is cooling because demand has collapsed.

On the U.S. side, the dominant macro signal came from the bond market rather than a data release. The 10-year Treasury yield dropping 9bps to 4.45% and the 30-year falling 8bps to 4.99% represent a meaningful easing of financial conditions. That move happened despite Warsh taking over with a hawkish posture and a January 2027 hike priced in. The bond market appears to be betting that the energy shock cools enough over the next 12-18 months to prevent further Fed action. The VIX falling 8.86% to 15.32 confirms that tail-risk pricing has come off, even if it has not fully normalized.

The single most important variable next week is whether the Hormuz negotiation produces any formal agreement or suffers another military incident. The "talk and strike" dynamic is live: Trump's May 27 Iran strikes happened while diplomatic channels were supposedly open. Any escalation snaps WTI back above $95, reverses the Nikkei's energy-import repricing, and puts the Warsh Fed in a worse position on inflation. On the data side, watch for any eurozone CPI confirmation that gives the ECB the green light for a June hike. A hot print locks in EUR/USD upside and puts FEZ under pressure from the rate side. U.S. PCE or jobs data, if released, will be read through the Warsh lens: anything that supports his hawkish pivot validates the January 2027 hike pricing and steepens the yield curve.

• EWJ (Japan): The Hormuz de-escalation trade has the clearest fundamental link to Japan's energy import bill. The Nikkei's +4.2% move has room to extend if negotiations advance. Size according to your tolerance for a snap reversal on military escalation.
• QQQ (US Tech/AI): Micron's +19.3% move to a $1 trillion market cap confirms that AI hardware demand is accelerating, not plateauing. The 10-year yield falling 9bps provides a rate tailwind for long-duration tech. The Nasdaq trade is AI-fundamental, not just macro.
• IWM (US Small-Cap): Small-caps outperformed large-caps this week, driven by rate sensitivity. The 10-year at 4.45% and moving lower gives domestic U.S. companies with floating-rate debt a direct earnings benefit. Watch this spread if Warsh hike expectations intensify.
• GLD (Gold): Gold gained +0.91% in a week when equities rallied sharply and oil crashed. It is not selling off. That persistence signals investors are maintaining macro hedges against Warsh Fed hawkishness and unresolved Middle East risk. Hold as a portfolio hedge alongside risk-on positions.
• FEZ / EWQ / EWG (European Equities): Underweight or avoid for now. The ECB's June hike signal, UK consumer collapse, and oil volatility are a triple headwind for European earnings. The Euro Stoxx 50's +1.08% masked intraweek selling in the CAC and DAX. Wait for ECB clarity before adding Europe exposure.
