Renewed tensions between the United States and Iran around the Strait of Hormuz have increased geopolitical risk across global energy markets, supporting crude and freight costs while East Asian bitumen buyers remain cautious.

Renewed military escalation between the United States and Iran has sharply increased risk around the Strait of Hormuz. The US has announced the reinstatement of its naval blockade on Iranian shipping, while both sides have resumed strikes across the region. Brent crude climbed to around USD 85/bbl on Tuesday, reflecting renewed concerns over shipping security, energy flows, and possible supply disruption.
For the East Asian bitumen market, the immediate impact is stronger cost and supply uncertainty rather than a clear recovery in regional demand. Higher crude prices, freight risk, and tighter confidence in Gulf-origin flows may support sellers’ offers, but buyers across Asia are still resisting elevated levels unless cargo availability, loading schedules, and delivery terms are commercially workable.
The regional market therefore remains divided. Singapore continues to receive support from tight supply, while South Korea and China are offering more competitive alternatives. Under current conditions, origin, loading availability, freight exposure, and execution certainty have become just as important as price
FOB Singapore bitumen prices strengthened to USD 605–615/MT. Most July-loading cargoes have already been committed, while August availability is also expected to remain limited due to feedstock constraints.
Buying interest for prompt cargoes reached around USD 615/MT FOB Singapore, although sellers showed limited willingness to conclude deals at that level.
Singapore remains the region's primary pricing benchmark. However, tight availability and elevated price levels mean it is no longer the most practical supply origin for every destination.
Bitumen demand in Malaysia improved with the commencement of infrastructure projects in Johor Bahru and several other states, although seasonal rainfall continues to slow road construction activities.
Export tank truck prices from Singapore remained stable at USD 640–650/MT Ex-Refinery. Malaysian buyers continued to resist higher-priced imported cargoes, while domestic supply has remained sufficient to meet current demand.
Malaysia remains an active market, but successful negotiations are likely to depend on confirmed project demand, delivery timing, and the overall commercial competitiveness of supply offers.
Bitumen consumption outside Java and Sumatra remained subdued, as the absence of new road construction tenders continued to limit demand growth.
A multi-port cargo was reportedly concluded at around USD 655–665/MT CFR, while most buyers continued targeting lower levels of USD 630–640/MT CFR.
Although inventories are gradually declining, seaborne prices remain above the budget expectations of many downstream consumers. Should urgent replenishment requirements emerge, this situation could create new trading opportunities.
Thailand continues to attract attention as an important alternative sourcing origin. Offer levels increased to around USD 610–615/MT FOB Thailand, although firm buying interest remained relatively limited.
August supply is expected to stay tight due to reduced refinery operating rates and ongoing feedstock constraints. At the same time, newly announced road construction tenders are expected to support domestic consumption.
Thailand remains a promising alternative supply source, although cargo availability should be carefully confirmed before concluding transactions.
Vietnam's seaborne demand remains constrained by the rainy season and comfortable inventory levels among importers. Nevertheless, some buyers continue to seek cargoes for immediate project requirements.
Indicative buying levels for Singapore-origin cargoes were reported at USD 630–640/MT CFR for both northern and southern Vietnam, while some lower indications emerged around USD 620–630/MT CFR.
Given Singapore's higher prices and limited availability, an increasing number of Vietnamese buyers have shifted their attention toward Chinese-origin cargoes.
FOB South Korea prices declined further to approximately USD 515–529/MT.
The latest refinery tender from Yeosu for August-loading cargoes was reportedly awarded at around USD 500/MT FOB South Korea, reviving arbitrage opportunities into Southeast Asia, although the available grade may not meet the specifications required by every buyer.
South Korea has once again become significantly more competitive than Singapore and deserves closer attention from buyers in China as well as several Southeast Asian markets.
Heavy rainfall, flooding, and slower road paving activity continued to pressure domestic Chinese bitumen prices.
East China ex-works prices declined to USD 702–717/MT, while South China ex-works prices were reported at USD 667–678/MT.
CFR East China levels eased to approximately USD 530–560/MT, while CFR South China was assessed at USD 590–610/MT.
August-loading South Korean cargoes were discussed near USD 530/MT CFR East China. Meanwhile, August-loading offers from South China were reported around USD 590–600/MT FOB, whereas Southeast Asian buyers continued targeting USD 585–590/MT FOB.
China continues to play a dual role as both one of the region's largest consuming markets and an increasingly important alternative export origin for Vietnam and Southeast Asia.
The recent rebound in crude oil prices is likely to provide near-term support for bitumen offer levels, although it does not fundamentally change the structural differences across regional markets.
In today's market, the best opportunities are not necessarily found at the lowest prices. Successful trading increasingly depends on aligning the right origin, grade, loading schedule, freight economics, and execution capability with each customer's actual requirements.
