原油相場
わが国石油会社の購入原油価格は、シンガポール時間午後4時30分（東京時間午後5時30分）の査定価格が基準です。プラッツ社によるドバイ原油の査定は「マーケット・オン・クローズ」（MOC）という手法で決定される。MOCとは、査定機関が独自に定めた30分程度の時間のなかで希望販売価格と希望買取価格を集め、同時間が終了する時点に最も近いタイミングで行なわれた約定価格をその日の価格とするもの。サウジアラムコは2018年10月1日より「Platts Oman」を「Dubai Mercantile Exchange」 (DME) の「Marker Price」に置き換えた。このため現在では、中東原油のアジア向け輸出価格は「Platts Dubai」と「Oman Marker Price」（DME）が基準です。※詳しくは会員限定ディレクトリをご覧ください。
