Summary

• Global equities closed lower amid escalating US-Iran conflict and surging oil prices, with the S&P 500 down ~1.3%, Nasdaq Composite slipping ~1.1%, and Dow Jones falling ~1.8% for the week ending March 13, marking multiple weeks of declines and pushing indices toward 2026 lows.

• Energy sector stood out as the clear winner, leading gains on oil's sharp rally, while semiconductors offered pockets of support from earnings strength; broader cyclicals and defensives lagged, with technology and growth names under pressure from volatility and inflation fears.

• Bond yields rose as curves flattened, reflecting pushed-out rate-cut expectations and stagflation concerns in Europe; fixed income saw outflows from duration-sensitive assets.

• Commodities delivered decisive moves, with Brent crude surging amid supply disruptions and Strait of Hormuz risks (prices well above recent levels, contributing to inflation worries), gold holding as a partial hedge, but broader risk-off sentiment weighed on base metals.

• The USD strengthened on safe-haven flows and higher-for-longer US rates, pressuring EUR/USD, GBP/USD, and emerging currencies amid flight to quality.

Market review: Geopolitical escalation fuels oil surge, volatility, and defensive rotation

The past week underscored how quickly active conflict can dominate market narratives. The ongoing US-Israel military operations against Iran, now in its third week with retaliatory strikes, missile exchanges, and disruptions in the Strait of Hormuz, sent oil prices sharply higher and injected fresh volatility across asset classes. This geopolitical shock amplified existing concerns around inflation persistence, delayed Fed easing, and potential stagflation signals from Europe, overriding softer underlying fundamentals in many regions.

US equities remained relatively resilient compared to the scale of the energy shock but still posted measured declines, with the S&P 500 down around 1.3% as broad selling pressure hit. Energy stocks led convincingly, benefiting directly from the oil rally and supply disruption fears, while semiconductors provided under-the-radar support from solid earnings beats. International markets fared worse: Europe grappled with stagflation worries and higher energy costs, Asia felt the pinch from rising oil and credit jitters. The rotation favored clear winners in energy and select defensives, but growth-oriented tech and cyclicals bore the brunt as risk premiums expanded.

Fixed income reflected the repricing: Treasury yields climbed and the curve flattened as investors dialed back near-term cut expectations amid higher inflation risks from energy. Quality credit held better than high-yield in the decompression.

Commodities told the starkest story—oil's surge marked it as the standout winner, driving energy sector outperformance and highlighting supply vulnerability, while gold offered some safe-haven appeal but couldn't fully offset broader risk-off flows. The stronger dollar compounded pressures on non-USD assets and emerging markets.

Overall, this was a classic geopolitical-driven week: energy and safe-havens as unambiguous winners, growth and duration as losers. Markets have historically shown resilience to such events, but the prolonged nature of this conflict, combined with tariff uncertainties lingering in the background, keeps volatility elevated and sentiment fragile. The conflict is indeed starting to hurt broader risk appetite and inflation outlooks.

The week ahead

A critical week lies ahead with major central bank decisions dominating amid the ongoing Middle East conflict. The Fed's interest rate decision (likely a hold, but tone will matter hugely) on Wednesday will be parsed for any acknowledgment of energy-driven inflation risks versus growth resilience—hawkish rhetoric could extend yield pressure and cap equity upside. Thursday brings the ECB decision (expected hold amid stagflation fears) and potential commentary on energy shocks; a dovish tilt might provide relative support to European names.

Other highlights include US retail sales mid-week (soft prints could counter inflation fears, favoring risk assets) and ongoing Iran developments—any escalation in strikes, Hormuz disruptions, or diplomatic breakthroughs could swing oil violently and dictate daily direction. Nvidia earnings remain a wildcard for tech sentiment.

My base-case: heightened volatility with a defensive bias. If the Fed signals patience on cuts and oil stays elevated, expect continued rotation toward energy, financials (from steeper curves), and gold, with broader equities consolidating or testing further lows (S&P potentially probing recent supports). Yields may edge higher toward 4.20-4.30% on the 10-year if inflation fears build. A surprise de-escalation or softer data could spark a relief bounce, but the conflict's persistence suggests choppy, headline-driven trading—position for energy strength and caution on growth multiples until clarity emerges.
