Insights Global

Insights Global is a Dutch market intelligence firm headquartered in Rotterdam that publishes the PJK ARA weekly oil stocks report, the standard reference dataset for Northwest European product inventories held in the Amsterdam-Rotterdam-Antwerp storage hub. Its survey samples roughly 70-80% of independent ARA tankage across gasoil, diesel, gasoline, naphtha, jet fuel and fuel oil, and is released every Thursday.

The firm's value is methodological rather than editorial: it does not trade or comment on the market it measures, it counts it. That distinction matters because ARA stock levels are themselves a proxy for refinery output, import flows and seasonal demand across the whole region, so a single independently-verified weekly print carries more weight than any single trader's estimate.

Across the european-oil-markets desk, PJK data has repeatedly been the first signal of shifts other reporting later explained, including the jet-fuel divergence from recovering gasoline and total stocks in its most recent print. That track record is why regional trading desks and transatlantic arbitrage models treat the Thursday PJK number as a primary price catalyst rather than one input among many.
