LONDON, Jan 9 (Reuters) - Northwest European gasoline refining profit margins fell by over $1 to $5.39 a barrel on Thursday, marking the lowest level in over a month, as independently held ARA inventories reached all-time highs.

* About 2,000 metric tons of Eurobob E5 barges traded. Shell sold to Gunvor.

* A further 4,000 tons of E10 gasoline traded. TotalEnergies sold to Varo.

* In the Platts window, BP offered a cif Thames gasoline cargo at $744 per metric ton, though no trades were agreed as buyers were not forthcoming.

* In the Platts Mediterranean gasoline window, Trafigura offered a cargo, while BP and Vitol sought cargoes. No trades were reported.

* ARA gasoline stocks rose by 8.5% on the week to 1.53 million tons, marking the highest level on record.

* Weaker exports helped prop up gasoline stocks, as shipments on the transatlantic route to the U.S. slowed, Insight Global's Lars van Wageningen said.

* New shipping fixtures appeared this week for transatlantic and African destinations, which could point to rising exports in the coming weeks, Lars van Wageningen said.

* EU-27 and UK gasoline exports reached 912,000 barrels per day in December, Kpler data showed, down from 1.17 million bpd in November.
