I wonder what their $59b cost is based on?
I've heard from multiple sources that about $9b per day in commerce goes through the Suez, so that's probably just $9b * number of days stuck. I imagine the cost is actually quite a bit more, as the ripple effect from this traffic jam will continue for at least another month while shipments are diverted or delayed until traffic pressure returns to normal.
It's not like the $9b of daily commerce that can't get through the canal is being set alight and tipped overboard, it will reach its destination in the end. Some of that produce might have gone off, or the delay in its arrival causes knock-on costs, but the final cost is only going to be a fraction of that figure, not a large multiple!
