The claim is strongly supported by the fetched Bloomberg article, 'Iranian Oil Trades at Premium to Brent for First Time Since 2022 - Bloomberg'. That article explicitly says Iranian oil traded at a $1-a-barrel premium to Brent on March 26, 2026, and that this was the first time since May 2022. It also characterizes the move as a sharp reversal from the steep discounts that had previously defined Iranian crude pricing. A corroborating search hit for 'Iranian crude trades at a premium to Brent after US waives sanctions' matches the user's additional detail about an earlier roughly $10 discount in early 2026, although that page could not be fetched and therefore cannot be treated as fully validated evidence in this run. Because the Bloomberg article directly confirms the core of the statement, the overall claim is likely true.
