Week of Jul 20 – Jul 27, 2026
The take
Commodities drove the year through July on Middle East supply tensions, but a fragile US-Iran ceasefire unwound oil's rally late in the month while Asian chip stocks cracked under AI-spending skepticism. DBC rallied 9.2% over four weeks, lifting commodity-tilted portfolios, but emerging-market equities tumbled 5.7% as Korean chipmakers shed double digits. The week ending July 27 was quieter—global equities flat, developed ex-US up 1.1%—as energy gave back gains and tech remained under pressure.

- This week — Calm week; developed ex-US equities up 1.1%, US down 0.4%, commodities soft.

- Year-to-date — Commodities define 2026; DBC +29.6%, emerging markets +13.7%, bonds flat to negative.
This week: a tentative bounce as oil retreated and developed markets diverged
The week ending July 27 opened with fresh US-Iran hostilities driving Brent above $85, but by midweek a memorandum of understanding eased immediate supply fears and crude tumbled. A fragile US-Iran memorandum of understanding eased immediate supply fears, allowing oil to give back much of its rally; DBC fell 0.4% despite the earlier surge. Developed ex-US equities (VEA) rose 1.1%, outpacing US stocks (SPY -0.4%), while emerging markets (EEM) edged up just 0.09% after steep prior losses. Bonds drifted lower—TLT down 0.2%—and gold rallied 1.9%. The choppy intra-week moves masked the larger story: portfolios that allocated to commodities early in the year held their YTD gains, while EM-heavy sleeves absorbed weeks of chipmaker pain.
Past 4 weeks: a commodity rally collided with an Asian tech rout
Brent oil gained more than 11% mid-July, rising above $85 a barrel for the first time in a month, as the US launched fresh strikes on Iran and President Trump reimposed a blockade on Iranian ships transiting the Strait of Hormuz. That propelled DBC up 9.2% for the four-week window, the single largest driver across model portfolios. Yet mounting concerns over stretched AI valuations triggered a selloff in chip stocks across Asia, with MSCI's EM gauge dropping as much as 2.7% and extending losses from a bull-market peak to 10%; EEM fell 5.7%. Long-duration bonds sold off sharply—TLT down 3.9%—as ceasefire optimism briefly dimmed, then returned. VEA slipped 1.3%. US equities held relatively steady, down just 0.3%. Commodities and EM equities moved in opposite directions, rewarding diversified portfolios that held both and punishing concentrated equity-only strategies.
Year-to-date: the commodity supply shock still anchors 2026 returns
Since year-end, DBC has returned 29.6%, reflecting the initial spike in energy and industrial-metals prices after the Iran conflict erupted in late February and the subsequent rallies each time hostilities flared. Emerging-market equities are up 13.7%, developed ex-US 11.5%, and the S&P 500 8.8%—all solid, but well behind commodities. Bonds have been a drag: TLT down 1.6%, reflecting the combination of sticky inflation and geopolitical premium baked into rates. Prices will remain elevated above pre-conflict levels through 2028 due to lasting infrastructure damage and significant geopolitical risk, according to S&P Global. Gold fell 5.9% YTD despite a late-month bounce, underperforming as real rates stayed positive. The YTD leaderboard is clear: portfolios that overweighted commodities early captured the year's dominant theme, while those anchored to bonds or underweight risk assets lagged.
