HIGHLIGHTS
Dubai, Oman premiums climb $1.40/b Aug. 27
Unipec sells 15 October partials to Mercuria
Three Oman convergences occur in August MOC
Cash differentials for Middle East medium sour crude markers rebounded during the Singapore Platts Market on Close assessment process Aug. 27.
Platts, part of S&P Global Energy, assessed October cash Dubai and cash Oman both at a premium of $10.78/b to same-month Dubai futures at the market close, up $1.40/b day over day.
October cash Murban was assessed $3.10/b lower, at a premium of $10.90/b to same-month Dubai futures.
During the MOC process, 15 October Dubai partials of 25,000 barrels each traded. Unipec was the sole seller, and Mercuria was the sole buyer.
Unipec declared a cargo of October Oman crude to Mercuria following the convergence of 20 partials in Platts cash Dubai.
A convergence occurs when 20 partials are traded between two counterparties in the same direction, resulting in a full 500,000-barrel physical cargo being declared from the seller to the buyer.
