Bloomberg shipping data show that of 109 large tankers (>=700,000 barrels)
trapped in the Persian Gulf after the Feb. 28 outbreak and the effective closure
of the Strait of Hormuz, 29 — roughly one quarter — have since made slow, covert
departures and transited the strait. Those cargoes account for only a small
portion of oil and refined products still held in the Gulf, but were rapidly
bought up as global inventory buffers are shrinking at a record pace. Many
vessels have been operating with AIS transponders off, so the true number of
successful evacuations is likely higher.
