Europe's voluntary carbon and energy certificate traders brace for capital flight as Brussels rewrites the rulebook A push to harmonise trading-venue rules and centralise oversight under ESMA has voluntary certificates desks worried liquidity will drain to less regulated venues. Brussels wants to cut the cost of doing business, and the bill is now landing on energy certificate desks. Under the EU's deregulation push, firms face roughly €60,000 to set up in each member state where they operate and €400,000 a year in running administrative costs, with trading-venue rules to be harmonised and supervision pulled toward the European Securities and Markets Authority.⁴ That matters because Europe's voluntary certificates markets — the lightly regulated venues where guarantees of origin and similar instruments change hands — fear the same reforms meant to unshackle the wider economy could push their liquidity elsewhere. Montel reported the worry directly: capital flight.⁴ The mechanism is straightforward. Tighter, centralised oversight raises the fixed cost of operating a venue. For high-margin equities that is absorbable. For thin voluntary markets, where the spread between attracting flow and losing it to a competing jurisdiction is narrow, a six-figure annual compliance bill is the difference between a functioning order book and an empty one.⁴ This lands on a power market already under stress. Andre Bosschaart, head of analytics at Montel EnAppSys, described the period two months into the negative price season as, in effect, a season of sub-zero prices, with Europe's low power prices diverging from his earlier outlook.² The negative-price problem is no longer a fringe statistic. In Germany, negative prices occurred 5% of the time in 2024, up from 3% in 2023, and in the first eight months of this year that share rose to 10%, according to figures cited by The Economist. "The market is screaming for capacity," said Michael Waldner, chief executive of Zurich-based renewable consultancy Pexapark.⁵ That capacity scream is the link to certificates. Voluntary instruments — guarantees of origin, green PPApaper — are how renewable revenue gets underwritten when the spot market keeps printing zeros and below. Eurelectric has argued that removing barriers to power purchase agreements is key to reducing the risks weighing on the clean-energy investment the EU needs to decarbonise.⁶ So the timing is awkward. Brussels is trying to de-risk green investment through PPAs on one hand while, on the other, redesigning the venue rules that the certificate side of that trade depends on. If the harmonisation drains liquidity from voluntary markets, the price signal those certificates are meant to provide weakens precisely when renewable developers need it most.^6,5 Power prices are unlikely to calm on their own. Industry experts told Montel that heightened volatility in the European power market faces further pressure from gas uncertainty and the prospect of a summer heatwave, with gas remaining the marginal price-setter.¹ Gas itself offers little reassurance. Russian output fell 3.2% to roughly 334.8 billion cubic metres by mid-year against the same period a year earlier, while LNG production dropped 5.1% to about 16.5 million tonnes, according to federal statistics cited in reporting on Russia's supply. Power-of-Siberia exports are projected to rise more than 20% this year toward the pipeline's 38 bcm annual ceiling, redirecting volume east rather than back to Europe.³ Not every corner of the continent is equally exposed. Improved hydropower availability in southeast Europe, combined with regional producers having bought gas in advance, is shielding that region's energy markets from demand destruction even as prices climb, regional analysts told Montel.⁷ The deregulation drive sits inside a broader bet. The EU wants to harmonise venue rules and hand more supervision to ESMA as part of a war on red tape, the same campaign aimed at making it cheaper to operate across the bloc.⁴ For voluntary certificate desks the question is whether centralised supervision delivers the deeper, more trusted pools that draw capital in, or the compliance overhead that drives it out. The two outcomes pull in opposite directions, and the reform text has not settled which wins.⁴ Watch where the liquidity goes. If voluntary venues start reporting thinner volumes as the harmonisation rules firm up, that is the capital-flight thesis confirming itself — and it will show up first in the certificate order books, not in the headline power price. The next signal is the detail of how ESMA's expanded remit treats the voluntary side versus the regulated carbon market.^4,2
