China's renewed demand for crude oil is leading to significant price increases across various global sources. The country's refiners are increasingly active in the spot market, particularly for Middle Eastern crude, pushing benchmark Dubai futures to nearly $100 a barrel, the highest since May. Premiums for Oman and Murban crude have also surged due to concerns over supply disruptions from Iran and its proxies, like Yemen's Houthis. This aggressive bidding from Chinese and Indian refiners is intensifying competition with buyers in South Korea and Japan.

The search for alternative supplies has led Chinese refiners to pay the highest premiums in over four months for ESPO, a key Russian oil grade. ESPO's popularity has soared due to its short transit time to China (less than a week) and the drying up of Iranian oil due to a US blockade. This shift highlights China's efforts to diversify its crude oil sourcing and bolster energy security, with state-owned petroleum companies actively ramping up domestic and overseas production.

Brazil has emerged as a crucial emergency oil supplier for Asia, filling the gap left by Middle Eastern disruptions. Its share of China's crude imports jumped from 10% in January to 18% in April, with 1.43 million b/d of Brazilian crude purchased by Chinese refiners last month—a new record. India is also a significant buyer, with Brazil becoming its fourth-largest crude supplier in April, sending around 290,000 b/d. Brazilian grades like Tupi and Buzios are appealing due to their medium-sweet crude characteristics, which are suitable for refineries aiming to maintain middle-distillate yields amid diesel and jet fuel shortages. Petrobras, Brazil's state-owned oil company, has significantly redirected its exports, with over 60% now going to China, having cut crude exports to the US to zero from approximately 60,000 b/d in March.

Despite a temporary dip in China's overall crude imports in April due to a supply shock, the strategic replacement of lost Gulf crude with Brazilian oil is evident. While the long 50-day voyage from Brazil to China presents freight cost challenges, it underscores the urgency of China's need for diversified supply. The upcoming availability of shorter-haul Russian Arctic barrels via the Northern Sea Route, which takes about 25-27 days, may temper China's reliance on Brazilian crude during certain periods. However, the combination of Gulf supply disruptions, increased Brazilian production, and crude specifications matching Asian refinery needs ensures Brazil's continued role as a vital, albeit distant, crude supplier for Asia.

Furthermore, Chinese exports of oil products are expected to recover, with proposed September exports of clean petroleum products exceeding 4 million tons, up from about 3.5 million tons previously planned. This recovery is attributed to more crude flowing to Chinese refineries from the Persian Gulf, allowing the government to ease war-related restrictions and ensure domestic supply, thereby providing some relief to tight global markets for gasoline, jet fuel, and diesel.
