Executive Summary 

June 2026 was a month of reversal and rotation rather than continuation. The oil-driven disinflation that began in May accelerated sharply following a mid-month U.S.-Iran peace framework, sending Brent crude down a further ~21% to close near $73 per barrel — its steepest monthly decline since March 2020 and, combined with May’s move, the worst quarterly performance for oil since 2020. Yet the macro tailwind did not translate into broad equity gains the way it did in April and May. Leadership rotated hard away from the mega-cap technology names that had driven the year’s rally and into small-caps, financials and industrials, while Kevin Warsh’s first meeting as Fed Chair delivered a hawkish surprise that capped the month’s gains for growth stocks. 

The S&P 500 was essentially flat for the month (-0.9%, closing at 7,499.36), snapping its eight-week winning streak, while the Nasdaq Composite fell -2.8% to 26,213.72 — its first monthly decline since February — as memory-chip cost pressures and AI-funding jitters weighed on mega-cap technology. The Dow Jones (+2.5% to a record 52,319.20) and the Russell 2000 (+3.0% to 3,024.37) told the opposite story, with small-caps closing out their best first-half performance since 1991. The month’s other headline event — the record-breaking SpaceX IPO, priced at $135/share and valued near $1.77 trillion — briefly made Elon Musk the world’s first trillionaire and added a fourth major storyline to a month already crowded with the Fed transition, the unraveling of the Iran war premium, and a fresh bout of Bitcoin weakness (down ~20% on the month, its worst since June 2022). 

Equity Markets Performance 

U.S. equity markets diverged sharply in June, breaking the tight correlation between the Nasdaq and S&P 500 that had defined the first five months of the year. The S&P 500 closed the month at 7,499.36, down approximately 0.9% from May’s close near 7,564, even as the index closed out its best quarter since 2020 on a combined April-June basis. The Nasdaq Composite fell to 26,213.72, a decline of roughly 2.8% from its May 29 close of 26,972.62, dragged down by a sharp mid-to-late-month pullback in mega-cap technology and memory-chip names after Apple and Microsoft raised consumer prices in response to surging memory costs, and after South Korea’s SK Hynix unveiled plans for a nearly $30 billion U.S. listing that added competing supply to the AI-memory trade. 

The Dow Jones bucked the trend, adding roughly 2.5% to close at a record 52,319.20, as investors rotated into financials, industrials and healthcare. The standout performer was the Russell 2000, which gained approximately 3.0% to close at 3,024.37 — capping the small-cap index’s best first-half performance since 1991 — helped by falling oil prices, a resilient domestic economy, and the June 26 Russell US Indexes reconstitution, a record $334 billion single-day rebalancing event. 

The month was punctuated by volatility around a fast-moving Iran storyline: stocks surged on June 15 on reports of a U.S.-Iran “peace deal” (the S&P 500 jumped 1.9% and the Nasdaq 3% in a single session), pulled back sharply in the days around Micron’s earnings and the SK Hynix listing news, wobbled again as President Trump accused Iran of violating the ceasefire in the week of June 26, and then rallied into quarter-end on strong Micron results, cooling inflation data, and the Dow’s and Nasdaq’s best-first-half/best-quarter milestones. 

Sector Performance 

June’s sector leadership looked almost like a mirror image of April and May, with cyclical and rate-sensitive names outperforming the AI-infrastructure trade that had dominated the year to that point. 

Information Technology (XLK): The month’s most volatile sector. Memory-chip and AI-infrastructure names came under pressure mid-month on funding and supply concerns — Micron and SanDisk both fell double digits around June 23-24 alongside broader Magnificent Seven weakness — before Micron’s blockbuster fiscal Q3 earnings, driven by AI memory demand, sparked a partial recovery into month-end. Apple’s and Microsoft’s price increases on consumer hardware, tied to rising memory and storage costs, underscored how the AI-driven memory shortage is now reaching end consumers. 

Financials & Industrials: Outperformed on a steeper yield curve, resilient economic data, and optimism around capital markets activity — SpaceX’s record IPO, SK Hynix’s planned U.S. listing, and continuing pre-IPO positioning around OpenAI and Anthropic all pointed to a busy back half of the year for underwriters. 

Energy (XLE): The month’s clearest laggard for a second consecutive month. Brent’s roughly 21% decline compressed the sector’s earnings outlook further, extending May’s profit-taking after the earlier war-premium rally. 

Communication Services: Held up better than the broader technology complex, supported by continued AI-monetization narratives at Alphabet and Meta, including reports that Meta is building a new cloud business to monetize excess AI computing capacity. 

Real Estate & Healthcare: Mixed. Real estate continued to be weighed down by a persistent commercial office supply overhang even as small-cap and value-oriented names generally benefited from the market’s read on a more durable disinflation trend; healthcare lagged as capital continued to favor cyclical exposure over defensives. 

Fixed Income 

The Treasury market spent June digesting a genuinely two-sided narrative: falling energy prices pulling yields lower, against a hawkish new Fed chair pulling them higher. The 10-year yield ended the month at 4.44%, almost unchanged from May’s 4.45% close, but the path there was volatile — dropping toward the low-4.40s in the days after the mid-month Iran “peace deal” announcement and again as oil fell to pre-war levels around June 24, spiking after the Fed’s June 17 meeting removed its easing-leaning forward guidance, and steadying into month-end as employment data was digested. 

The marquee fixed income event of the month was Kevin Warsh’s first FOMC meeting as Fed Chair on June 17. The Committee voted unanimously (12-0) to hold the federal funds rate at 3.50%-3.75% for the fourth consecutive meeting — a sharp contrast to the contentious 8-4 split at the prior chair’s final meeting in April — but the accompanying Summary of Economic Projections delivered a hawkish surprise: the median year-end 2026 rate projection rose to 3.8% from 3.4% in March, flipping the Committee’s own base case from an implied cut to an implied hike, with 17 of 18 participants judging inflation risks to be tilted to the upside. Warsh, in a break from convention, declined to submit his own dot, calling the tool premature for a chair only weeks into the role, and unveiled a dramatically shortened policy statement (130 words versus 341 in April) that dropped forward guidance entirely. He also announced five internal task forces — covering the Fed’s inflation framework, labor-market data, communications, balance-sheet policy, and productivity — with initial findings expected by year-end. 

The hawkish turn was driven by inflation data that continued to run hot even as the oil shock unwound: May CPI came in at 4.2% year-over-year, the highest reading in more than three years, with energy costs up roughly 23.5% year-over-year on the lagged effects of the Iran conflict; core CPI was a more moderate 2.9% year-over-year (+0.2% month-over-month). May PPI rose 6.5% year-over-year, a leading indicator of further pipeline pressure. Fed funds futures ended the month pricing in odds as high as ~77% of a rate hike by December 2026 — up sharply from the ~46% priced at the end of May and a complete reversal from the two-cut base case investors held at the start of the year. 

Commodities 

Metals 

Gold had its worst month in nearly two decades. The metal fell from a close near $4,524 at the end of May to roughly $4,000 by June 30 — a decline of close to 12%, its steepest monthly drop since October 2008 and a fourth consecutive monthly loss. The proximate cause was the Fed’s hawkish June 17 pivot, which pushed real yields higher and sapped demand for the non-yielding metal just as the dissipating Iran war premium removed the safe-haven bid that had underpinned prices through the spring. Central bank buying continued — roughly 89% of central banks have publicly committed to further gold accumulation, according to World Gold Council survey data — providing a structural floor that most analysts believe differentiates the current correction from gold’s 45% collapse following the 2013 “taper tantrum,” but it was not enough to prevent the sharpest one-month move since the financial-crisis era. 

Silver tracked gold’s broader retracement over the month, though it continued to show more two-way volatility given its dual role as a monetary and industrial metal, with falling oil prices providing some offset via lower input costs for industrial buyers. 

Energy 

Oil extended May’s historic decline. Brent crude opened June near $95 and closed the month around $73, a drop of roughly 21% — the steepest monthly decline since March 2020. The catalyst was a genuine, if fragile, diplomatic breakthrough: a “peace deal” between the U.S. and Iran was announced around mid-month (first via a Pakistani-brokered statement, then confirmed by President Trump), followed by a memorandum of understanding calling for the reopening of the Strait of Hormuz and a 60-day ceasefire framework, alongside a U.S. Treasury license authorizing Iranian crude exports through August. Tanker traffic through the Strait recovered quickly, and Iran said it had shipped more than 40 million barrels since the naval blockade was lifted, compounding a supply glut alongside record Russian export volumes. 

The rally in prices proved fragile, however. Renewed clashes between U.S. and Iranian forces near Bahrain and Kuwait in the final days of June — and Iran’s insistence on retaining a co-regulatory role over Strait of Hormuz shipping traffic — sent Brent swinging within a wide range over the month and left delegations shuttling to Doha for further talks as June closed. Morgan Stanley cut its Q3 Brent forecast to $90 and its Q4 forecast to $80; Citi was more bearish, cutting its Q3 forecast to $75 and its Q4 forecast to $70. Goldman Sachs flagged the risk of prices spiking back toward $120-140 should the ceasefire collapse and the Strait close again. 

Cryptocurrency 

Bitcoin had its worst month since June 2022. The token opened June near $73,700 and slid in a persistent, low-volatility decline to close near $59,000 — down approximately 20% for the month and roughly 34% year-to-date, with essentially no intra-month relief rally. Spot Bitcoin ETFs recorded more than $4.5 billion in net outflows during June, their weakest month on record, compounding a similar wave of outflows in May. The proximate drivers were the same hawkish Fed repricing that hit gold, a reported first-ever coin sale by Strategy (formerly MicroStrategy), and continued whale distribution; quarter-end de-grossing by funds exaggerated the final leg of the decline on June 30, when Bitcoin briefly traded below $58,000 with the Crypto Fear & Greed Index falling to 18 (“extreme fear”). The total crypto market capitalization ended the month near $2.1 trillion, down from $4.3 trillion at its October 2025 peak. 

International Markets 

MSCI EAFE (Developed): European equities benefited from the same disinflation impulse supporting the rest of the world, with euro-area headline inflation easing to 2.8% in June (from 3.2% in May) as energy price pressure from the Iran war continued to fade. European indices, including a record-setting run in Italy’s FTSE MIB, capped a strong second quarter overall. 

MSCI Emerging Markets: China’s CSI 300 had a strong month, touching its highest level since December 2021 (above 5,000) in the third week of June before easing into quarter-end on profit-taking and rebalancing flows; onshore sentiment continued to be supported by strong factory and tech-export data and continuing state-linked buying, even as offshore MSCI China sentiment remained more cautious. 

India (Sensex/Nifty): Indian equities staged a sharp reversal from May’s sell-off. The Sensex closed June near 76,479, up approximately 2.3% from May’s close of 74,776, as falling oil prices eased pressure on India’s import bill and the rupee, and foreign institutional selling abated. The rebound was not without cross-currents: the Nifty IT index fell sharply in the final session of the month (down 2.7% on June 30 alone) as continuing concerns about AI-driven displacement of outsourced technology services weighed on Infosys, TCS and Wipro, even as domestically-oriented sectors — realty, consumer durables, and pharmaceuticals — outperformed. 

Outlook: July 2026 

Four variables will dominate July. 

First, the durability of the Iran ceasefire. Renewed clashes in the final days of June and Iran’s insistence on a co-regulatory role over the Strait of Hormuz leave the 60-day truce framework more fragile than markets priced through most of June. A breakdown would reverse much of the disinflationary progress and put upward pressure on both oil and the Fed’s rate path; a durable extension, by contrast, would likely support the continued rotation into rate-sensitive small-caps and cyclicals. 

Second, the fallout from SpaceX’s record IPO. SpaceX is scheduled to join the Nasdaq-100 before the market open on July 7, with J.P. Morgan estimating roughly $4.3 billion of forced passive inflows from the index-inclusion event. The stock’s extreme post-IPO volatility — an intraday round trip from its $135 IPO price to $225.64 and back below $155 within three weeks — and its outsized weighting relative to its tradeable float will be a live risk factor for index-fund flows and single-stock volatility alike.
