Argus Group Three RBOB
Argus recently launched a calculated assessment for reformulated gasoline in Group Three. This move comes following recent changes that were made in gasoline specifications for the Denver, Colorado, area in 2024.
Summertime conventional gasoline sales in Denver, Colorado ended on 7 November 2023 when the US Environmental Protection Agency (EPA) mandated reformulated gasoline for the metropolitan area during the summer season. The shift in specifications was first announced by the EPA ruling in November 2022 when it found the region was not meeting federal ozone standards. Reformulated gasoline burns cleaner than its conventional counterpart but is also a more expensive fuel to produce.
For the winter months, Denver gasoline prices will likely change little from years past. The Reid Vapor Pressure (RVP) levels for reformulated gasoline will likely closely mimic those seen in Group Three’s conventional gasoline market for the southern portion of the midcontinent.
But come summer – which is defined as 1 June through 15 September – Denver area retailers will be required to sell 7.4 RVP reformulated gasoline, as opposed to a prior requirement of 7.8 RVP conventional fuel. This is expected to widen Denver's premium to conventional prices in nearby regions.
Denver reformulated gasoline's premium to sub-octane gasoline prices in adjacent states such as Oklahoma and Kansas should be similar to spreads between Gulf coast CBOB and Gulf coast RBOB. Denver's reformulated gasoline supply will come from a combination of shipments from the midcontinent and Gulf coast markets, as well as from Suncor's 103,000 b/d refinery in nearby Commerce City, Colorado.
Group Three RBOB Methodology
Prices for Regular RBOB are published year-round for 10,000 bl on a fob Tulsa, Oklahoma basis.
Prices are calculated by applying the spread between the prompt Argus Regular Texas Destination RBOB and Regular Colonial CBOB from the US Gulf coast markets to the respective prompt Magellan suboctane V grade price. The use of the spread value mitigates the end-of-summer shift in Colonial RVP specifications.

Hormuz traffic Thursday flat from day earlier
Hormuz traffic Thursday flat from day earlier
New York, 28 August (Argus) — Commercial vessel traffic through the strait of Hormuz on Thursday remained constrained despite assertions by US officials that the waterway was open to commercial traffic and free of mines. A total of 12 vessels transited the strait of Hormuz on 27 August, the same number as a day before , according to data from maritime security firm Windward. The traffic was equally split between inbound and outbound movements, including four tankers inbound on the northern Iranian lane, three outbound tankers on the southern lane and one outbound on the northern lane. This puts commercial vessel traffic through the waterway just under 10pc of the normal traffic levels prior to the 28 February US-Israel attack on Iran that prompted Iran to declare the strait closed. Admiral Brad Cooper, commander of the US Central Command (Centcom), which oversees US forces in the Mideast, said in a video post late on 27 August that internationally recognized transit lanes in the center of the strait are free of Iranian mines and that "today, international shipping lanes are open and momentum is building". No vessels were detected by Windward as transiting via the center lane on that day. Traffic since the start of the US-Iran war has been largely bifurcated between the northern and southern lanes. Prior to the war, ships transited the strait through the centermost lane via an established Transit Separation Scheme (TSS) route. The TSS was proposed by Oman and Iran and adopted by the IMO in 1968, designating shipping lanes for maritime traffic to reduce collisions and improve safety. Following the outbreak of the US-Iran war, the middle TSS lanes were reportedly mined by Iranian forces, rendering traffic through them highly dangerous. A combination of factors are likely to make vessels easier to target if they are transiting in the center of the strait compared with transits closer to the coastline, said Joshua Tallis, research program director at the Center for Naval Analyses (CNA). This includes a more complicated sensor environment closer to the coast and proximity to missile defense systems. US officials continue to double down on claims that the US had been supporting significant flows of oil through the waterway. Centcom's Cooper said US forces have assisted nearly 1,500 commercial vessels through the strait by providing coordinated protection, with a total of 750mn bl of crude oil destined for global markets "over the past several months". In the three months before the war started crude flows averaged 700mn bl a month, Vortexa data show. In a late Thursday social media post US Treasury secretary Scott Bessent echoed claims by other US officials that in the last 14 days the US has guided 130mn bl out of the strait of Hormuz. That figure, which approximates to 9.3mn b/d, is in line with the 9mn-10mn b/d claimed by other US officials including US president Donald Trump, but far below the 3.5mn-3.7mn b/d average that can be corroborated by available satellite imagery and vessel tracking information.

ExxonMobil Rotterdam refinery limited since outage
ExxonMobil Rotterdam refinery limited since outage
London, 28 August (Argus) — ExxonMobil's 200,200 b/d Rotterdam refinery is still producing less than normal volumes in late August, following a power outage earlier in the month, according to several market sources. ExxonMobil declined to comment. A source said output was disrupted at least for diesel and residual fuel oil. Another said they had been "waiting ages" to load from the refinery and then told to load from a different location. Another said there had been no barge loadings for "a while" but operations could restart by the end of August. Another said they expected the issue to persist into September. The refinery was affected by a power outage on 13 August. Dutch emergency services said all processes stopped at the site , which was related to a fire at a transformer substation in the Maasvlakte district of Rotterdam port.

Japan’s Eneos to keep Middle East as main crude source
Japan’s Eneos to keep Middle East as main crude source
Tokyo, 28 August (Argus) — The Middle East will continue to be Japanese refiner Eneos Holdings' main crude source, but dependence on the strait of Hormuz could be lowered depending on the cost and risk balance, executive vice president and chief financial officer Soichiro Tanaka said in an interview with Argus . "The Middle East will remain a crude source with a significant share, although its share may decline from past levels," Tanaka said. The firm will return to Middle Eastern crude to some extent as the situation stabilises, given its economic advantages and the firm's experience of processing Middle Eastern crude as its main crude supply. Nationwide, Japan has started discussions to diversify crude oil sourcing, including a scheme to raise funds from refiners and importers to support diversification. "If it becomes an economically viable framework and offers greater overall value in various respects, we will choose to make use of it," Tanaka said. The framework will have influence on Japan's future dependence on the Middle East for crude, but "Middle Eastern crude will not drastically decrease," he said. Japan sourced 94pc of its crude imports from the Middle East in 2025, and most of the volumes passed through the strait of Hormuz. To reduce geopolitical risk, Japan is also considering financial measures to support construction and enhancement of alternative supply facilities in the Middle East, such as pipelines bypassing the strait. Reducing reliance on the strait "depends not only on buyers but also on suppliers' measures such as pipeline construction," Tanaka said. "Hopefully, it will settle at the point where risk and cost are best balanced, but that is beyond our control," he added. Currently the disruption at the Bab el-Mandeb strait is affecting Eneos' crude procurement, but the level is limited and Eneos can still meet domestic supply, he said. "Some adjustments have been necessary, but there is no supply shortage. It is a matter of timing and a temporary structural fluctuation." Exploring overseas potential Eneos as a group aims to raise its overseas revenue to around 50pc in the April 2030-March 2031 fiscal year. As part of this strategy, the company has announced plans to acquire petroleum assets in southeast Asia and Australia from Chevron, including its 50pc share of Singapore Refining Company's export-oriented 290,000 b/d refinery, as well as terminals and supply networks in southeast Asia and Australia. The firm has not fully utilised its capacity to conduct trading, and there is potential here, Tanaka said. The acquisition of assets in southeast Asia will provide a return in trading backed by assets, he reiterated, highlighting the expected growth in demand for petroleum in the region. The growth in southeast Asia's demand for petroleum could also be a key driver for the Japanese refiner to seek a broader market to absorb Japan's expected surplus of refining capacity, since Japanese demand is on a downtrend. "We are not considering any immediate action. But over time, refining capacity will be somewhat excessive relative to domestic demand. On the other hand, demand will continue to grow in southeast Asia," Tanaka said. "We will determine the future refining capacity based on how much overseas markets such as southeast Asia grow and whether supply from domestic refineries can be used there." "It is a matter of how we balance between the future outlook and marginal refineries, so it is an issue that we need to assess on an ongoing basis," Tanaka said. Eneos has around 1.64mn b/d of refining capacity in Japan, accounting for the largest share in the country's overall capacity around 3.11mm b/d. "There are no specific projects under consideration, but we are looking at whether there is still room to expand further in the downstream business in southeast Asia," Tanaka said. Eneos is also exploring the possibility of expanding overseas business in other sectors. The company has also recently announced the plans to acquire US-based chemical producer TPC Group . "The US market is attractive given the competitiveness of ethane crackers and feedstock," Tanaka said. Eneos is also focusing on southeast Asia as the "core area" for upstream business including the LNG sector and aims to expand it, Tanaka said.

Singapore's Aster to buy aviation fuel JV Cafhi stake
Singapore's Aster to buy aviation fuel JV Cafhi stake
Singapore, 28 August (Argus) — Singapore energy and chemicals firm Aster will buy a stake in Changi Airport's fuel storage and infrastructure joint venture Changi Airport Fuel Hydrant Installation (Cafhi), it said today. This will allow Aster to supply aviation fuel directly to international airlines at Singapore's Changi Airport. The transaction is subject to the requisite approvals and the fulfilment of customary closing conditions, Aster said. Further details such as the timing of the acquisition will be shared when appropriate, Aster told Argus on 28 August. It also declined to comment on the percentage of shares due to commercial sensitivities. Singapore's Sustainable Aviation Fuel Company (SAFCo) had required participants in its trial SAF tender to be a Cafhi member, or work with a member to supply volumes into the airport. Other Cafhi members include shareholders ExxonMobil, Shell, BP, TotalEnergies, and Singapore Petroleum Company (SPC), as well as Singapore-based sustainable aviation fuel (SAF) producer Neste, which has a minority stake. Aster previously partnered with fellow Singaporean firm Keppel in January to build one of Asia's first commercial-scale alcohol-to-jet (AtJ) SAF plants. The facility will be situated on Singapore's Jurong Island and have a planned capacity of 100,000 t/yr. The project is currently in its front-end engineering design (Feed) phase, which is targeted to be completed in next year's first quarter, a source familiar with the matter told Argus . Aster is also working with US-based climate technology firm Aether Fuels to develop a 2,000 t/yr next-generation SAF facility at its refining and petrochemical complex on Singapore's Pulau Bukom. The plant, named as Project Beacon, is scheduled to begin construction in 2027 and commercial operations in 2028, a source familiar with the matter told Argus . The plant will use Aether's enhanced Fischer-Tropsch (FT) technology to convert industrial waste gas and biomethane into Carbon Offsetting and Reduction Scheme for International Aviation (Corsia)-certified SAF.
