Worse than SWIFT

Yesterday, Maersk and MSC stopped delivering their containers to Russia. These are two monopolists in this field, what does that mean?
Nothing is delivered by sea and nothing goes by sea. Apart from the covers, oil and gas equipment, combines, products, electronics and spare parts are not delivered. Even if you have your own production, you still need to deliver some spare parts - it is not. Imports and exports are completely stopped and it's worse than disabling SWIFT.
