What if Denmark closes its straits to Russia's shadow fleet?
Denmark halting shadow-fleet tankers in the Danish Straits chokes Baltic Urals loadings from Primorsk/Ust-Luga, widening Urals discounts and forcing Russia to idle barrels; long dated Brent vs Urals is the trade, VIX bid on escalation risk. Rhymes with the 2022-23 G7 price-cap enforcement waves, which dented Russian export volumes at the margin but were largely arbitraged via dark fleet. Transmission: Russia funds budget via these barrels; India/China are the swing buyers. Forward angle: insurance-fraud pretext is harder to dark-fleet around than the cap.

What it would mean
If this plays out, it is a risk-off shock. Denmark halts shadow-fleet tankers in its straits over insurance fraud, snarling Baltic Russian crude exports.
