Asian oil buyers are taking advantage of falling shipping costs to purchase more crude oil from Africa and Brazil, creating fresh opportunities in the global oil market. After tanker freight rates dropped sharply from record highs, crude grades from the Atlantic Basin have become more affordable and attractive to Asian refiners.
Among the major buyers are China’s Unipec, the trading arm of energy giant Sinopec, and South Korea’s SK Energy. Both companies have reportedly secured vessels at significantly lower freight rates to transport West African crude to Asia in December.
Unipec has already purchased two cargoes of Congo’s Djeno crude at discounts of approximately $22 per barrel against dated Brent on a free-on-board basis, according to traders familiar with the transactions. The company has also provisionally chartered two Suezmax tankers to transport West African crude to Asia, with shipments scheduled between late November and early December. A very large crude carrier (VLCC) has also reportedly been arranged for an early December loading.
South Korea’s SK Energy has similarly provisionally chartered a Suezmax tanker to transport crude from Gabon to Ulsan in December. The reported transactions highlight how lower transportation expenses are influencing purchasing decisions among major Asian refiners.
According to analysts at Energy Aspects, softer long-distance VLCC freight rates are making crude grades from west of the Suez Canal increasingly competitive. Higher premiums for Russian ESPO crude could also encourage Chinese buyers to consider heavier Angolan oil as an alternative.
Why falling tanker rates are changing the oil market
The latest buying activity follows a period of unusually high shipping expenses that pushed up the cost of importing crude oil into Asia.
Last month, tanker freight rates across several vessel categories reached record levels as Middle Eastern oil producers increased exports. The situation was further complicated by security concerns linked to the US conflict with Iran, which prompted some shipments to use ship-to-ship transfers outside the Strait of Hormuz.
Demand for tankers also increased as Chinese independent refiners shifted towards non-sanctioned crude following disruptions to Iranian exports. Their efforts to use remaining annual crude import quotas before the end of the year added further pressure on shipping capacity.
With transportation costs rising, many Asian refiners became more cautious about purchasing additional cargoes. This reduced activity in the spot market and contributed to weaker crude prices.
However, the situation has since changed. More vessels have become available following the completion of earlier deliveries, allowing freight rates to fall considerably.
A trader closely monitoring African and Brazilian crude transactions estimated that the delivered cost of these supplies to China has declined by approximately $5 to $10 per barrel compared with the previous month.
Baltic Exchange data also indicates that freight rates for VLCCs operating outside the Strait of Hormuz, along with Suezmax and Aframax tankers, have fallen by around 50% from their previous month’s peaks.
Vortexa shipping analyst Wanying Zhang attributed the correction to improved vessel availability following the exceptionally tight shipping market in October. The number of laden mainstream VLCCs and Suezmax vessels in East Asia has increased by approximately 15% since early September, indicating that more ships could become available as existing cargoes are discharged.
Angolan and Brazilian crude become more competitive
The decline in shipping costs is also improving the price competitiveness of Angolan and Brazilian crude in China, the world’s largest oil importer.
A Chinese independent refinery based in Shandong province has reportedly purchased one million barrels of Angolan Plutonio crude for delivery in late December or early January. The transaction was completed at a premium of approximately $15 per barrel above ICE Brent.
This represents a notable change from just two weeks earlier, when Angolan crude grades were reportedly trading at premiums exceeding $20 per barrel.
Brazilian crude is also becoming more affordable. Tupi crude was recently traded at a premium of approximately $7 to $8 per barrel against December dated Brent for January delivery. This compares with premiums approaching $20 per barrel in the previous month.
The difference highlights how quickly changing shipping expenses and market conditions can influence the competitiveness of international oil supplies.
Last month, offers for Brazilian and West African crude reportedly climbed above $20 and $40 per barrel in premiums, respectively, reflecting the pressure created by expensive transportation and strong demand for available vessels.
Meanwhile, Asian buyers purchasing US West Texas Intermediate (WTI) crude continue to use Aframax tankers, which typically carry between 500,000 and 700,000 barrels. Although VLCC freight rates have eased from their peaks, they remain relatively expensive for certain routes.
Despite declining WTI prices, Abu Dhabi’s Murban crude was still reportedly around $2 per barrel cheaper, according to one trader.
What this means for global oil trade
The recent developments demonstrate that crude oil prices are not determined by production costs and supply alone. Transportation expenses, shipping availability, geopolitical developments, sanctions and regional demand all play important roles in determining which suppliers remain competitive.
For Asian refiners, lower freight rates are creating opportunities to diversify their crude supplies and negotiate more attractive purchasing arrangements. African and Brazilian producers could benefit as their oil becomes more accessible to major buyers, particularly in China and South Korea.
The situation also highlights how quickly the economics of global energy trade can change. A crude grade that was too expensive to purchase last month may become an attractive option when shipping costs decline.
For oil traders, refiners and energy companies, the coming weeks will be important in determining whether the recovery in shipping availability continues and whether Asian purchasing activity strengthens further.
Ultimately, the global oil market is not just about who produces the cheapest crude. It is also about who can deliver it at the right price, at the right time and with the lowest possible transportation cost. As shipping expenses continue to influence buying decisions, Africa and Brazil may find themselves playing a more significant role in meeting Asia’s energy demand.
