U.S.-Iran strikes put $100 oil back in focus. By Tom Kool - Sep 01, 2026, 10:10 AM CDT U.S.-Iran strikes reignite fears of a prolonged Middle East conflict as Hormuz tensions push regional oil benchmarks above $100. Rising Bond Yields Turn Oil's Rally Into a Demand Risk - Global bond yields have surged to their highest since 2008, as rising oil prices perpetuate fears of longer-than-assumed inflation, in turn creating a cycle of lower demand further down the road. - The rally in bond yields started in earnest after new Federal Reserve chairman Kevin Walsh vowed to finally tame US inflation, currently at 3.4%, sending yields on the 10-Year Treasury bonds to 4.76%. - The bond spiral extended into other developed economies, with rates on 10-year Japanese bonds touching a 30-year high and moved above 3%, whilst 10-year UK bonds surged to 5.2%. - Higher yields raise borrowing costs for households and companies, slowing vehicle purchases, air travel, construction, manufacturing and freight - all leading to demand destruction - whilst simultaneously pushing up the cost of drilling, pipelines and large upstream developments. - Marking a return to contractionary monetary policy, the market is pricing an almost 60% chance that the Federal Reserve will hike rates by a quarter-point at its meeting this month. Market Movers - US midstream giant ONEOK (NYSE:OKE) has acquired Brazos Midstream's natural gas gathering and processing assets in West Texas for a consideration of $4.4 billion, boosting its gas processing capacity by 1.2 bcf/d. - Oil majors Shell (LON:SHEL) and Chevron (NYSE:CVX) have signed a preliminary agreement with the government of Ghana to enter the South Deepwater Tano oil block, in water depths of 3,000m, the country's first new offshore license since 2018. - Norway's state oil firm Equinor (NYSE:EQNR) has signed its 2nd binding offtake agreement, alongside project partner Standard Lithium, for the SW Arkansas lithium project, with the LG Energy Solution contract marking a major step towards an FID later this year. - UK-listed upstream specialist Energean (LON: ENOG) is reportedly in exclusive negotiations with UK major BP (NYSE:BP) to acquire part of the latter's Egyptian upstream portfolio, in a deal valued around $1 billion. - Norwegian upstream firm DNO (OSL: DNO) is set to buy UK upstream independent Capricorn Energy for $0.4 billion after outbidding the offer of Kurdistan-focused driller Genel Energy, boosting its portfolio with assets in onshore Egypt. Tuesday, September 01, 2026 The first exchange of direct US-Iran attacks in a month has reignited fears that conflict in the Middle East might well last into 2027, with US President Trump threatening further strikes after its attack on Larak Island. Washington's sanctions on Tehran are making Hormuz transits ever more difficult, with Saudi Aramco's attempt to boost flows from the Persian Gulf immediately nipped in the bud by Tehran's drone attacks. Whilst ICE Brent is currently trading at $92 per barrel, Middle Eastern benchmarks have moved past $100 per barrel again. Hormuz Recovery Stalls After New Tanker Strikes. Two VLCCs carrying Saudi oil (Sidr and Senegal Prosperity) were hit by projectiles while exiting the Strait of Hormuz on Tuesday, threatening the fragile rebound in Gulf oil exports, just as Aramco lifted August loadings in the Gulf to 700,000 b/d. Trump Slams Brakes on Fuel Economy Rules. The Trump administration is preparing to slash US vehicle fuel-economy requirements, rolling back stricter Biden-era standards and requiring a fleetwide average of 34.5 miles/gallon by 2031, down from the previous 50.4 miles/gallon target. Texas Refiners Brace for Edouard. Saudi-owned Motiva and ExxonMobil (NYSE:XOM) are preparing their refineries in Port Arthur and Beaumont for the arrival of Tropical Storm Edouard, activating storm-response measures as Edouard is expected to turn into a hurricane and make landfall today. US Secures Major Venezuelan Oil Access Deal. Venezuela has signed a long-term agreement covering 17 oil fields with more than 65 billion barrels of proven reserves, granting U.S.-backed operators (mostly Alejandro Betancourt's NABEP) a leading role in upstream development.

Trans Mountain Seeks Final Expansion Push. Buoyed by Asian demand, Canada's federally owned pipeline giant Trans Mountain has applied to expand Its pipeline system by a further 210,000 b/d, aiming to lift total capacity to nearly 1.2 million b/d by late 2028 at an estimated cost of $2.9 billion. Russia Expands LNG Shadow Fleet. Russia has doubled the fleet serving its sanctioned Arctic LNG 2 project to 20 vessels, accelerating efforts to sustain LNG exports to China via the Northern Sea Route despite Western sanctions, just as August LNG loadings soared to a record high of 650,000 tonnes. Zinc Rally Hits Four-Year High. Zinc prices climbed to their highest level since 2022, hitting $3,980 per tonne this week, as mine disruptions, constrained Iranian supply and falling concentrate availability squeezed the market, the 5th monthly gain for the best-performing metal of 2026. Solar Overtakes Coal in China's Capacity Race.

Saudi Arabia Turns to Fresh Borrowing Amid Wartime Strains. Saudi Arabia is exploring at least $8 billion in new loans, underscoring Riyadh's push to diversify funding sources as the Iran war dents economic activity, with the kingdom posting a 4.8% year-over-year GDP contraction in Q2 2026. Bessent Signals Weekly Iran Sanctions Blitz. US Treasury Secretary Scott Bessent said Washington is preparing to roll out new Iran-focused secondary sanctions every week, initially targeting banks and financial institutions, intensifying its "maximum economic pressure" campaign against Tehran. Europe's Industry Pushes to Delay EU Methane Rules. 20 energy industry associations are urging the EU to postpone its methane emissions regulation for 3 years until 2030, warning of legal risks for oil and gas importers as any long-term deals would willingly and knowingly breach applicable EU law. Egypt Targets Q4 Restart for Damietta LNG. Egypt expects the Damietta FSRU damaged in a July drone attack to resume operations in Q4 2026, claiming that the loss of 5 mtpa regasification capacity did not impact the Egyptian market thanks to rising domestic natural gas production. Chile's Economy Stumbles as Storms Hit Copper Output. Chile's economic momentum weakened sharply in July as severe winter storms disrupted mining operations and pushed copper production to its lowest July level since 2011, posting a 10% year-on-year drop to 403,424 metric tonnes.

Brazos Midstream, which the company describes as the largest privately held midstream platform in the Midland Basin, is expanding its processing capacity to 1.2 Bcf/d by 2027 through the Cassidy II plant project.
ONEOK to buy Permian assets from Brazos Midstream in $4.425bn deal. Apollo-managed funds and affiliates will provide a $9bn nonvoting minority equity investment to finance the transaction. 31st Aug 2026 ONEOK has signed a definitive agreement to acquire Brazos Midstream's natural gas gathering and processing assets in the Permian Midland Basin for $4.425bn in cash. The deal is expected to close in the fourth quarter of 2026, subject to regulatory approvals and customary conditions. The transaction will be financed by a $9bn nonvoting minority equity investment from funds and affiliates managed by Apollo. ONEOK plans to use $5bn from this equity investment to repay existing debt, targeting a pro forma 2027 leverage ratio of approximately 3.25 times debt-to-EBITDA. The company stated there will be no issuance of common equity in connection with this acquisition. The acquired assets include about 700 miles of gathering infrastructure and 1.2 billion cubic feet per day (bcf/d) of processing capacity across seven Permian Midland Basin counties. This infrastructure is supported by roughly 600,000 dedicated acres under long-term fixed-fee contracts, with a weighted average remaining term of more than 12 years and currently features 14 active drilling rigs. Upon completion of the Cassidy II processing plant, expected in the third quarter of 2027, the combined operations will more than double ONEOK's Midland Basin processing capacity to nearly 2.3bcf/d, including plants under construction. The company also obtains a Permian Midland Basin-wide area of mutual interest with a private producer, allowing for additional growth opportunities. ONEOK expects the acquisition to be immediately accretive to earnings and free cash flow per share. The deal values the assets at approximately 7.5 times estimated 2027 EBITDA, inclusive of about $80m in full-year synergies, and about six times estimated 2028 EBITDA. ONEOK president and CEO Pierce Norton II said: "This transaction demonstrates ONEOK's strategy of intentionally expanding and extending our integrated energy infrastructure. These assets add a premier Permian Midland Basin platform supported by long-term contracts and attractive growth opportunities. "The acquisition expands our scale in the Permian Midland Basin, advances our integrated wellhead-to-water strategy and strengthens connectivity across our natural gas and NGL value chain, positioning ONEOK to capture significant volume growth in one of the most economic and rapidly growing resource plays." Apollo's minority equity investment consists of a Class B interest in a new holding company, with a 7% internal rate of return capped for the first nine years. The acquisition and the minority equity investment were both unanimously approved by the ONEOK board of directors. The minority equity investment is scheduled to close in the first half of September, subject to standard closing conditions. Barclays was the sole financial advisor to ONEOK on the Brazos Midland transaction and lead advisor on the minority equity investment, with Lazard also advising on the latter. Legal counsel to ONEOK was provided by Latham & Watkins. Apollo was advised by RBC Capital Markets and Milbank, while Brazos Midstream was advised by Akin Gump Strauss Hauer & Feld.

ONEOK to acquire Brazos Midland gas assets for $4.425 billion. ONEOK has agreed to acquire Brazos Midstream's natural gas gathering and processing assets in the Permian Basin's Midland sub-basin for $4.425 billion in cash, expanding the midstream operator's footprint in one of the largest U.S. oil and gas producing regions. The acquisition will be funded as part of a separate $9 billion nonvoting minority equity investment from funds and affiliates managed by Apollo Global Management. ONEOK plans to use roughly $5 billion of the Apollo proceeds to extinguish existing debt, while the remainder will fund the Brazos acquisition. The structure allows ONEOK to finance the transaction without issuing common equity. The company said the combination of the Apollo investment and planned debt reduction is expected to bring its pro forma 2027 debt-to-EBITDA ratio to about 3.25 times. Brazos' Midland Basin system is supported by roughly 600,000 dedicated acres under fixed-fee contracts with a weighted average remaining term exceeding 12 years, according to ONEOK. Producers operating on the acreage include ExxonMobil, Diamondback Energy and Double Eagle, with 14 active drilling rigs currently supporting the system. After completion of the Cassidy II processing plant, which ONEOK expects in the third quarter of 2027, the acquired system is expected to comprise about 700 miles of gathering infrastructure and 1.2 billion cubic feet per day of gas processing capacity across seven Midland Basin counties. ONEOK said adding the Brazos assets would more than double its Midland Basin processing capacity to approximately 2.3 Bcf/d, including facilities currently under construction. The company expects to link those volumes with its broader natural gas liquids infrastructure, including the West Texas NGL Pipeline and its Medford fractionation project. The acquisition continues a multiyear expansion of ONEOK's U.S. midstream portfolio. The company completed its $14.1 billion acquisition of Magellan Midstream Partners in 2023, adding major crude oil and refined-products infrastructure. In 2024, ONEOK paid about $2.6 billion for Medallion Midstream and $3.3 billion for Global Infrastructure Partners' controlling interest in EnLink Midstream, before acquiring EnLink's remaining publicly held interests in January 2025. ONEOK estimates the Brazos purchase price at about 7.5 times projected 2027 EBITDA, including approximately $80 million of anticipated annual synergies, falling to roughly six times projected 2028 EBITDA. The company also expects the acquisition to be immediately accretive to earnings and free cash flow per share. The Brazos acquisition has been approved by ONEOK's board and is expected to close in the fourth quarter of 2026, subject to customary conditions including U.S. antitrust clearance. The Apollo investment is separately expected to close in the first half of September. By Charles Kennedy for Oilprice.com More Top Reads From Oilprice.com
US ONEOK to buy Permian assets of Brazos Midstream for $4.425 billion. Al Greenwood 31-Aug-2026 HOUSTON (ICIS)-ONEOK has agreed to purchase the Permian Midland assets of Brazos Midstream for $4.425 billion, a deal that includes natural gas processing plants and gathering pipelines, the US-based midstream company said. Processing plants extract ethane, propane and other natural gas liquids (NGLs) from the raw natural gas that is produced as a byproduct from oil wells. Ethane is the predominant feedstock of the ethylene plants in the US. ONEOK will be extracting a larger amount of these chemical feedstocks through its purchase of the Brazos assets. The acquisition should close in the fourth quarter. The following lists some of the highlights of the deal: * By the third quarter of 2027, the Brazos acquisition will add 1.2 billion cubic feet/day of processing capacity in the Midland basin. * The Brazos acquisition will also add 700 miles of gathering infrastructure. * The Brazos assets are supported by 600,000 dedicated acres under long-term fixed-fee contracts. "These assets add a premier Permian Midland Basin platform supported by long-term contracts and attractive growth opportunities," said Pierce Norton II, ONEOK CEO. "The acquisition expands our scale in the Permian Midland Basin, advances our integrated wellhead-to-water strategy and strengthens connectivity across our natural gas and NGL value chain, positioning ONEOK to capture significant volume growth in one of the most economic and rapidly growing resource plays." PERMIAN IS MAJOR SOURCE OF CHEM FEEDSTOCKS The acquisition underlies the growing importance of the Permian as a source of feedstocks in the chemical industry. Ethane and other NGLs are extracted from the associated gas produced from the basin's oil wells. These wells account for most of the growth in crude production in the US, according to the Energy Information Administration (EIA). The rise in production of associated gas has been accompanied by increasing gas processing capacity. Midstream companies like ONEOK are building natural gas processing plants and acquiring existing assets in the Permian. Notably, Enterprise Products has also acquired midstream assets, most recently Occidental Petroleum's in August 2025. Midstream companies are also exporting NGLs to chemical plants around the world. ONEOK should join these exports in 2028 when it completes its first export terminal through its Texas City Logistics joint venture with MPLX. The terminal will be in Texas City, Texas, and it should export 400,000 barrels/day of liquefied petroleum gas (LPG).
