European carbon had its worst month in a year, and the reasons had almost nothing to do with carbon. President Trump's decision to ramp up tariffs against all trading partners, the EU's pause on approving its trade deal with Washington, and rising war tensions combined to trigger a sell-off that included the second-weakest EUA auction since the ETS began. This week is a clean lesson in what now moves carbon prices: everything else.
Carbon Trades as a Macro Asset
Monday's slump after the weak auction confirmed bearish sentiment, and Friday's sell-off sealed the largest monthly loss in a year. Bank analysts went further, warning that a dramatic shift in Europe's political landscape over the past two years has raised the likelihood that policymakers weaken climate targets and water down ETS ambition. None of this changes the structural supply story, but it changes who holds allowances and why. Carbon is now held alongside energy and equities by traders who sell it when the world gets scary. Expect volatility on headlines that have nothing to do with emissions.
CBAM Survives Its Biggest Trade Test
The week's most consequential structural news was easy to miss: India and the EU published the full legal text of their free trade agreement, and it confirms CBAM remains fully applicable. Brussels resisted the temptation to trade away its carbon border for a deal, which tells exporters, Indonesian producers included, to stop hoping the mechanism gets negotiated away. In parallel, an analysis showed hydrogen import competitiveness under CBAM will hinge on embedded emissions, and Norway moved to end double carbon pricing for ETS-covered industry. The architecture is hardening, not softening.
Africa Keeps Building
Under the macro noise, supply-side infrastructure kept advancing. Six Congo Basin countries unveiled Article 6 roadmaps developed with World Bank support; most Sub-Saharan governments started 2026 pushing long-awaited carbon regulations; fourteen African governments committed a combined $400 million to forest management with the FSC. The pattern from January holds: while the US steps back and Europe argues, new supply regions organise. Pre-COP31 will be hosted by Fiji in October, putting the Pacific on the calendar too.
What This Means for Investors
Three takeaways. First, carbon's correlation with geopolitical risk-off moves is now a portfolio fact; size positions for headline-driven drawdowns that have nothing to do with fundamentals. Second, CBAM's survival inside the India FTA is the strongest signal yet that the carbon border is permanent; build compliance strategies around it, not against it. Third, Africa's Article 6 build-out is systematic, with multilateral backing; early exposure to well-governed new supply regions remains the asymmetric trade.
