What happened

How the US naval blockade has bled Iran of nearly $6bn in oil revenues Iran is exporting less than one-sixth of the oil it was shipping before the war began.

Why it matters

Iran’s crude oil exports fell to their lowest level in at least six years in May, as a United States naval blockade squeezes Tehran’s most important source of income amid a fragile ceasefire between the two nations.

Common ground

The blockade on Iran’s ports, which Washington commenced on April 13, is part of President Donald Trump’s effort to pressure Iran to agree to its terms for a peace deal.

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
