The price of Kuwaiti crude fell by $7.38 to $81.31 per barrel in Tuesday's trading, down from $88.69 per barrel in trading last Friday, according to figures from Kuwait Petroleum Corporation (KPC).

The decline came as international benchmarks also moved lower. Brent crude fell by $1.08 to $91.49 per barrel, while US West Texas Intermediate slipped 81 cents to $86.04 per barrel.

The figures show all three grades trading lower in the latest sessions. However, the gap between them remains notable. Brent continues to command the highest price of the three, ahead of West Texas Intermediate, while Kuwaiti crude is now priced below both of the global benchmarks.

For Kuwait, the latest reading marks a move from just under $89 per barrel at the end of last week to a little over $81 by Tuesday, according to KPC's published prices.

KPC's figures set Tuesday's Kuwaiti price at $81.31 per barrel. On international markets, Brent closed at $91.49 per barrel and West Texas Intermediate at $86.04 per barrel.
