Last week saw recent trading patterns repeat as ACCUs traded choppily around sporadic SMC flows. Despite this, analysis indicates prices remain well supported, with 87% of year-to-date activity trading within a tight $1/t range – the lower bound of which has accounted for 23% of turnover alone.
With the surrender deadline for the large-scale generation certificate (LGC) compliance market passing last week, market data published on our EnergyIQ platform indicates that LGC traded volumes increased over the 2025 compliance year, led by a large increase in options trading.
In this update, we also summarise the key outcomes of the recently published Carbon Leakage Review, discussed further in this morning’s Briefing note.
