May 2026 - Investment Newsletter

KEY TAKEAWAYS

>>  The Iran war dominated geopolitics in May, with a largely nominal ceasefire and Strait of Hormuz restrictions disrupting about 20% of global oil flows. Brent crude spiked above $111 before falling nearly 15% on tentative but unresolved U.S.–Iran deal optimism, reigniting inflation concerns and market volatility.

>>  Q1 2026 U.S. real GDP growth was revised down from 2.0% to 1.60%, confirming a modest expansion driven by strong business investment, particularly in AI and intellectual property, while the Q2 outlook remains clouded by energy-driven inflation, moderating consumer spending, and a growing divergence between resilient manufacturing activity and softer services demand.

>>  The Federal Reserve has kept policy rates on hold at 3.50%–3.75% following its April meeting, as persistent inflation and macro uncertainty continue to cloud the outlook; under newly appointed Chair Kevin Warsh, officials have emphasized a flexible, data-dependent approach, with market expectations for eventual rate cuts pushed further out and a growing willingness among some policymakers to consider additional hikes if inflation remains elevated.

>>  The labor market remained resilient through May despite ongoing macroeconomic headwinds. Initial jobless claims edged higher to 215,000 from 210,000 the prior week, but the four-week moving average stayed near historic lows, reflecting a continued low-layoffs, low-hiring environment even as hiring momentum shows early signs of moderation.

  • Consumer confidence weakened further in May, with the University of Michigan Consumer Sentiment Index falling to a new record low of 44.8, revised down from a preliminary reading of 48.2 and marking a third consecutive monthly decline, as higher gasoline prices, rising inflation expectations, and broader cost pressures weighed on household sentiment and spending behavior.


  • Growth outside the U.S. remained more constrained, with Europe facing greater sensitivity to elevated energy prices and geopolitical risks; the European Central Bank has highlighted increased uncertainty around inflation and growth but has not definitively committed to additional rate hikes, instead signaling a data-dependent policy path, reinforcing global policy divergence.


  • The U.S. dollar strengthened over the course of the month, supported by shifting rate expectations, persistent inflation, and safe-haven demand amid geopolitical uncertainty, contributing to tighter global financial conditions and influencing cross-border equity and capital flow dynamics.


  • U.S. equities extended April’s rally with a more moderate gain, as the S&P 500 posted its ninth straight weekly advance to new highs to close the month, supported by strong earnings, continued AI‑driven technology leadership, and outperformance from healthcare and defense stocks, with signs of gradually improving market breadth.


  • International equities generally advanced, led by strong emerging market performance, while Europe lagged due to higher energy dependence, currency pressures, and a more cautious growth backdrop, reinforcing the regional divergence seen earlier in the year.


  • Treasury yields were volatile, with the 10-year reaching a 15-month high of 4.60% and the 30-year breaching 5% amid inflation concerns and increased term premium, before pulling back late in the month as oil prices softened, resulting in a modest steepening bias while overall rate levels remained elevated versus April.


  • Fixed income markets remained under pressure amid elevated yields and rising rate uncertainty, although a late-month pullback in oil prices provided some relief. Credit and high-yield markets were relatively resilient, supported by solid corporate fundamentals, even as rate volatility and higher yields continued to pressure longer-duration assets.


  • May highlighted a complex and evolving backdrop, characterized by resilient corporate earnings and labor markets alongside weakening consumer sentiment, persistent inflation pressures, shifting rate expectations, a stronger U.S. dollar, and unresolved geopolitical risks. In this environment, a disciplined, diversified, long-term investment approach, anchored in strategic objectives rather than short-term reactions to headlines, remains the most effective framework for navigating uncertainty.

ECONOMY

Solid U.S. Real GDP Growth in Q1


  • U.S. real GDP grew 2.6% year-over-year in Q1 2026, while annualized quarter-over-quarter growth was revised down to 1.6% from 2.0%, reflecting softer services consumption and weaker contributions from investment and inventories, partly linked to Middle East conflict disruptions.


  • Consumer spending slowed to 1.4% in Q1, but still improved sequentially from 0.5% in Q4, highlighting a more moderate but still positive contribution to overall growth amid rising inflation and declining sentiment.


  • Near-term growth expectations remained highly uncertain, with Fed nowcasting models diverging between roughly 1% and 4%, as markets await additional clarity from upcoming labor market and ISM data to assess the trajectory of Q2 growth and the implications for monetary policy.

U.S. GDP Growth

Consumer Confidence Weakens Further


  • Consumer confidence deteriorated in May, with the University of Michigan Sentiment Index falling to a record low of 44.8, marking a third straight decline and signaling increasing strain on household finances.


  • The decline was driven by rising gasoline prices tied to Strait of Hormuz disruptions, alongside elevated inflation expectations and broader cost pressures across essential goods and services.


  • Forward-looking sentiment weakened, with consumers increasingly concerned inflation will persist beyond energy and continue to erode purchasing power.


  • The divergence between resilient economic data and declining confidence points to a more cautious spending backdrop, reinforcing downside risks to consumption in the months ahead.

USD Bounces Back


  • The U.S. dollar strengthened modestly in May, with DXY rising 0.8% as shifting rate expectations and Fed repricing drove a mid-month advance and reversed earlier weakness.


  • Inflation surprises and more hawkish policy signals triggered a repricing toward a higher-for-longer rate environment, reinforcing dollar strength and contributing to its strongest weekly gain since March.


  • Persistent geopolitical uncertainty and elevated oil prices provided some safe-haven support, keeping the dollar near cycle highs and reinforcing a supportive backdrop as expectations for delayed rate cuts remain in place.

MARKETS

Equities Rallied in May


  • U.S. equity markets advanced in May, with major indices reaching new highs as the Nasdaq and S&P 500 delivered strong monthly gains, supported by continued earnings strength and sustained technology leadership.


  • AI-driven earnings momentum remained the primary driver of performance, with technology leading gains across sectors, while energy lagged amid oil price volatility tied to ongoing U.S.–Iran ceasefire negotiations.


  • Market breadth improved during the month, with small caps also advancing, while global performance remained uneven, as Asia and emerging markets outperformed and Europe lagged due to weaker growth dynamics and higher energy sensitivity.

Major Index Performance - Total Return

Fixed Income Market Stress


  • Treasury yields moved sharply higher during May, driven by persistent inflation, fiscal concerns, and geopolitical risk, with the 10-year approaching ~4.7% and the 30-year rising above 5.1% mid-month before retracing modestly.


  • A bear-steepening dynamic emerged as term premium and supply concerns pressured the long end of the curve, with the 10Y–2Y spread widening meaningfully.


  • Credit markets remained relatively resilient despite higher rates, with investment-grade and high-yield spreads holding broadly stable, supported by solid corporate fundamentals and continued demand for income.


  • High yield performance masked underlying rate volatility, highlighting that market pressure remained concentrated in sovereign duration rather than credit risk.



Credit Spreads

Commodities Remain Volatile


  • Commodity markets remained highly volatile in May, driven by the U.S.–Iran conflict and disruptions in the Strait of Hormuz, which created sharp swings in energy prices while supporting select non-energy commodities.


  • Oil prices spiked early on supply disruption fears before declining as ceasefire optimism, demand concerns, and alternative supply routes reduced geopolitical risk premia.


  • Precious metals experienced notable intra-month volatility but finished broadly unchanged, while wheat declined modestly amid softer demand and ample global supply.


  • Industrial metals were more resilient, with copper rising on strong demand tied to data-center build-outs and broader electrification trends.
