A Look At The Active ISK Delta In June 2025

On Wednesday CCP Games published the June monthly economic report (MER) for EVE Online's Tranquility shard. Before taking a look at the Active ISK Delta for last month I'd like to point out the events and trends developers considered most noteworthy in the economy.

Economic Summary

• Production value has declined to levels last seen in April. A similar downward trend is visible in Mining value, which has now reached its lowest point this year.
• All top four sink categories have returned to the levels recorded prior to May.
• We may be seeing the first signs of MPI stabilization - it recorded a modest increase of 1.01% compared to May, marking the first uptick since the major update in March.

With the general housekeeping out of the way we can now take a look back not only last month but last quarter.

Jester's average concurrent user chart

First, the summer slump wasn't held off by the Legion expansion. Launching at the end of May, concurrency peaked in early June before falling around 15% by the end of the month. For the quarter concurrency was down a few hundred users compared to the beginning of April.

For the month, EVE continued the trend of having above average Active ISK Delta values in the month of June. The Active ISK Delta is the net effect on the money supply of players leaving and returning to the game, including all GM actions. The actual ISK removed through these movements last month was 760 billion ISK, which in an economy with over 2,500 trillion ISK rounds to zero percent. 

Quarterly results

For the quarter the Active ISK Delta was positive for the fourth time in 7 1/2 years. As a percentage of the money supply only Q4 2023 and the Havoc expansion added a higher percentage of ISK than the 1.6% added in Legion and the accompanying major null sec war in the second quarter of 2025.

Most ISK removed in a month

What should an observer expect to see in July? Last July player movement into and out of the game resulted in 6.3% of the money supply leaving the game. I would not be surprised if that amount were not surpassed this year. After all, the ACU fell by over 15% in June. The summer slump is a real thing and might set up the conditions for a new record.
