That's precisely how you close the straits; by making everyone scared to go through.

You don't even have to scare everyone. You just have to scare the insurers. Without insurance ships won't sail. The exposure is huge, so a small blip in risk makes all the modeling go kerplooie. Traffic stopped when the insurers said drop the anchors.

To restore traffic, we need that risk to return to previous levels, which requires diplomacy and trust. I don't expect resolution any time soon.
