Oil Cracks and Colombia Breaks Ranks: June's Cross-Asset Scorecard

From 29 May to 30 June 2026 a hawkish new Fed lifted the dollar, crude fell nearly 18%, and Latin America's currencies split — Colombia's peso up 6% even as Brazil's real slid.

June was shaped by a regime change at the Federal Reserve and the unwinding of oil's war premium. New chair Kevin Warsh's first FOMC on 17 June held the funds rate at 3.50–3.75% but flipped the “dot plot” toward a hike — nine members now see higher rates by year-end — pushing up the dollar and front-end yields and pressuring risk assets broadly.

The clearest casualty was crude. WTI ended the month near $69 a barrel as reports of a U.S.–Iran ceasefire extension and a reopening Strait of Hormuz drained the geopolitical premium that had inflated prices in May. The result was a red scorecard almost everywhere — with one loud exception in the Andes.

Equities, rates and commodities via US-listed ETF proxies (SPY, EWZ, ARGT, IEF, CPER, USO), which are USD-denominated and differ from a local index close; USO tracks front-month WTI futures and overstates spot crude's fall. Currencies show the local currency's return vs the US dollar (positive = stronger vs USD).

Commodities and equities take the hit

Oil led the declines: the USO oil fund fell about 17.6% month-to-date. That front-month proxy overstates spot's move, but the direction is unambiguous — Brent, which averaged roughly $107 in May, was trading in the low-$70s by late June. Copper slipped 2.9% to seven-week lows as a firmer dollar and soft Chinese demand — China's new-energy-vehicle output fell early in 2026 — weighed on the metal.

Equities held up better than crude but still finished lower. The S&P 500 eased 1.3% around the hawkish Fed, while Latin American markets fared worse — Brazilian equities (EWZ) dropped 3.9% and Argentina's S&P Merval (via the ARGT ETF) fell 6.5%, the weakest equity market on the board. Ten-year Treasuries were the calm center, essentially flat (IEF −0.1%): the front end sold off — the 2-year yield jumped to about 4.2% after the meeting — while the 10-year held near 4.45%, a textbook hawkish flattening.

Latin America splits

The month's real story was currency divergence. Brazil's real weakened 2.5%, back to about R$5.18, as an election-year fiscal impulse — a R$700bn stimulus package, income-tax relief and gross public debt above 81% of GDP — kept investors wary even after the central bank trimmed the Selic rate to 14.25%. The Mexican peso was steadier, off roughly 1.1%.

The Colombian peso ran the other way entirely, gaining about 6% to around 3,440 per dollar — its strongest in years — after presidential-election results that markets read as a turn toward fiscal consolidation and friendlier energy policy. It was the only green bar on the board, and it did it while oil, a core Colombian export, was collapsing. With the Fed leaning hawkish and crude's risk premium gone, the dollar stays a headwind for emerging markets; June showed it is now idiosyncratic politics — Colombia's ballot, Brazil's budget — that decides who outruns it.
