Oil prices aren't much different than last week, but they're still 50% higher than before March and the war started.

One blockade or two, still cuts off that route either way so adding the second one doesn't make much difference, but the oil that lubricates and facilitates trade and manufacturing has a 20% lower global supply and a 50% higher price than before the spring with no sign of that ending soon.
