How does it matter that it's traceable? Everyone knows the ships going in and out thanks to AIS. Many of these ships are already either falsely flagged, sanctioned, or just Iranian flagged. And as far as paying in rubles or yuan, this tells me that Iran doesn't think the shipping companies are willing to pay in either or think there's a safe/effective way to accept payment through those currencies.

I'm curious what makes your think these ships are unknown. There are 2 blockades in place and suspicion of mines in the conventional shipping route through Omani controlled waters.

The significance of being traceable is simply that US could tell you to not abide by Iran's insurance scheme by threatening sanctions if you do.

Whereas if it's not traceable then all that others know is that your ship got through the strait and there's at least some plausible deniability of why it got through

Iran is already sanctioned. The actors willing to ignore the US's feedback on Iran's insurance plans are already not playing by US rules. This is insurance for the shipping companies that are already operating on sanctioned fleet and oil.

More than USA would sanction you if you start paying terrorists to pass a strait, none of the big players wants that.
