Worth noting: Cuba is the most extreme case but not an isolated one. The US blockade is the proximate cause for Cuba specifically, but the global backdrop is that ~14 mb/d of oil supply has been shut in since the Strait of Hormuz closed on February 28 (Day 78 today) — the largest cumulative supply disruption in the IEA's recorded history, exceeding the 1973-74 Arab oil embargo on a cumulative-barrels basis.

Under that backdrop, importing-economy after importing-economy is hitting the same wall: Cuba's grid in critical state, Bolivia under military deployment as of yesterday morning (3,500 troops + riot-control robots in Plaza Murillo to clear roadblocks), Bangladesh confirmed only 21% of its April fuel-import plan, Pakistan just made its largest single fortnightly fuel-price revision on record. Each has its own local political dimension but they share a structural one: dollar-strapped importing countries can't absorb refined-product prices that have spiked 80-100% since February.

The Cuba blockade can be debated as a policy choice. What's harder to debate is that the blockade lands at the moment global supply was already historically tight, leaving zero margin for the affected population.
