BofA: The Saudis Are Readying for a Long Oil Price War

  • Bank of America: Saudi Arabia is preparing for a prolonged oil price war to regain market share.

  • U.S. shale is more vulnerable than in past price wars, needing $65+ WTI to stay profitable amid rising costs and geological limits.

  • Bank of America: The oil price war is likely to be long and shallow instead of short and steep.

Saudi Arabia is getting ready to engage in a protracted oil price war with its rivals, Bank of America’s leading commodities expert told Bloomberg on Monday. According to Francisco Blanch, BofA’s head of commodities research, the unfolding oil price war is going to be “long and shallow”, rather than “short and steep” as the Kingdom tries to claw back lost market share, especially from U.S. shale producers.

Last month, OPEC+ announced a third output increase of 411,000 b/d for the month of July, a similar clip to the previous two months. Commodity experts began warning last year that Saudi Arabia was willing to ditch its traditional role as OPEC’s swing producer by abandoning its unofficial price target of $100 a barrel in favor of increased output. Saudi Arabia accounted for 2 mb/d of the group’s 3.15 mb/d in output cuts before it started unwinding in April.

Traders are now bracing for hard times, with oil futures traders betting that the ongoing unwinding of production cuts by OPEC+ will eventually lead to a supply glut and even lower oil prices. According to the latest Commitment Of Traders (COT) report by CME Group, open interest in calendar spread options hit record levels in the current week, with speculators holding the biggest net position bets on weaker U.S. crude futures curve since 2020.

Oil futures charts are flashing an unusual “hockey-stick” shape of the curve, with oil markets pricing tight supply through 2025, followed by an oversupply in 2026, according to the report. The spread between the WTI July contract and the August contract narrowed 3 cents on June 5 to $0.93 a barrel, while the spread between the December 2025 contract and the December 2026 contract widened by 10 cents to $0.53.

There is a lot of risk in the trade,” Nicky Ferguson, head of analytics at Energy Aspects Ltd, told Yahoo Finance, adding that rising activity is being driven by “strong prompt, weak deferred balances, and a very changeable geopolitical environment that makes holding futures difficult.

This is hardly the first time that Saudi Arabia is engaging in a race to the bottom with its rivals. The kingdom has undertaken a similar strategy at least twice over the past decade, with varying degrees of success. U.S. shale producers successfully weathered the 2015 oil price war by rapidly reorganizing into a meaner and leaner production machine that could breakeven at WTI price of as low as $35 per barrel, down from $70 per barrel just a few years earlier. Five years later, the U.S. Shale Patch required the direct intervention of then U.S. President Donald Trump, whose threats of withdrawing military support for Saudi Arabia persuaded de facto Saudi ruler Crown Prince Mohammed bin Salman to toe the line and abandon the oil price war.

Unfortunately, U.S. shale producers are more vulnerable this time around: a March Dallas Fed Energy Survey found that the U.S. Shale Patch requires WTI prices of $65 per barrel or more to drill profitably. U.S.  rig counts have declined 4% Y/Y and are now 7% below the 5-year average as producers scale back drilling activity amid rising costs. Tariffs on U.S. steel imports are partly to blame here, increasing the price of fracking equipment. Meanwhile, geological constraints are also posing a significant obstacle to efforts to ramp up production as the nearly two-decades-old U.S. shale boom plateaus. The EIA has predicted a small increase in U.S. crude output to 14 million barrels per day in 2027, up from 13.2 million barrels in 2024.

That said, Saudi Arabia and OPEC+ do not have carte blanche to continue flooding the markets with oil: the Kingdom needs Brent price of at least $96.20 per barrel to balance its books in fiscal year 2025, approximately $30 per barrel higher than current Brent price. Further, the country drew down considerably on its foreign exchange reserves in past oil price wars, limiting its ability to sustain another long war now.

However, Saudi Arabia is likely to gain more leverage in future showdowns as it continues to diversify its economy. The country is accelerating its $2.5 trillion mining plans, while also investing in technologies to optimize oil production and lower carbon emissions. Saudi Arabia’s mineral reserve potential has grown dramatically over the past decade, from $1.3 trillion forecasted eight years ago to $2.5 trillion currently. The Kingdom has set a goal to rapidly grow the mining sector, with its contribution to the economy expected to jump from $17 billion to $75 billion by 2035.

Too Busy to Focus on Your Happiness? Try Daily Micro-Acts of Joy

Researchers, led by UC San Francisco, tested the effectiveness of a weeklong, web-based wellbeing intervention, known as the Big Joy Project. This consisted of daily micro-acts, which included asking someone to share a fun, inspiring, or proud moment, making a gratitude list, and performing a kind act to brighten someone’s day. Approximately 17,600 people from around the world participated: most were from the United States, Canada and Great Britain (71%), female (84%), white (74%), with at least some college education (94%).

What They Discovered:

  • After the seven-day intervention, participants reported higher levels of wellbeing and positive emotions, and a stronger belief that one’s own behavior can promote happiness. They also reported decreased stress, and improved health and sleep quality.
  • Younger, Black and Hispanic, and socially disadvantaged participants benefited the most.
     

Why It Matters:

  • Improvements in wellbeing are associated with a lower risk of future mental illness and better physical health. “People with higher wellbeing are less likely to develop chronic conditions, like cardiovascular diseases, and have reduced mortality in both healthy and unhealthy populations,” said senior author Elissa Epel, PhD.
  • Web-based wellbeing interventions that last several weeks and take 3 to 4 hours a week to complete have shown favorable results. But this is the first time that a short intervention has shown such strong benefits, and it could work for more people.

“Many people lack the time, motivation, and resources to commit to these lengthier programs, and they may be more likely to drop out,” said first author Darwin Guevarra, PhD, who is also affiliated with Miami University. “We were excited to get positive results in a program that required just a few minutes each day for a week.”

Happy to hand over the keys to a robot? Augmented reality might help





University of South Australia





Would you trust a driverless car? A 2024 global survey involving nearly 8000 participants suggests most people are wary of handing over the steering wheel to sensors, cameras and computer algorithms.

However, a new study by Australian and French researchers shows that augmented reality (AR) could increase overall confidence in autonomous vehicles by simulating the experience and allowing drivers to personalise the AR interface.

The University of South Australia (UniSA) and IMT Atlantique created a sophisticated virtual reality driving simulator using headsets, testing seven AR visualisations with 28 participants, where information about driving conditions was added, modified and even removed from the simulation.

The participants were aged 22-50 and included 18 males and 10 females.

AR can deliver real-time, critical information directly onto the windshield or dash, alerting drivers to potential hazards and obstacles, speed limits and navigation directions. The technology uses sensors to deliver the data, ensuring that drivers stay focused on the road while accessing critical information.

Driving-related AR visuals included navigation paths, incoming vehicle alerts and pedestrians; and non-driving visuals ranged from aesthetic modifications to points of interest, such as cafes and dinosaur parks.

The researchers found that participants’ trust in autonomous vehicles was “significantly increased” when AR was used to add or change driving-related information, tailoring visual cues based on a driver’s preference, attention patterns and stress levels.

“Trust is a major barrier to the widespread adoption of autonomous vehicles,” says UniSA and IMT Atlantique PhD candidate Hoa Tran, who led the study.

“Despite autonomous vehicles being generally safer than human drivers in routine conditions, there is a global reluctance to fully embrace them, but augmented reality might be able to change that.

“The AR visuals helped participants understand the autonomous vehicle’s decision-making process, which is especially important in complex traffic scenarios,” Hoa says.

Even non-driving related additions, like landmarks or interior design enhancements in the car, improved trust among users. However, they also carried a greater risk of driver distraction.

Conversely, removing certain types of information – such as unnecessary pedestrian visuals or visual obstructions in the car – was helpful for reducing mental clutter, but it negatively affected user confidence.

“The message is that less isn’t always more,” says co-author UniSA researcher Dr James Walsh.

“The design of AR in autonomous vehicles needs to balance clarity with user comfort and personal preference.”

Researchers suggest future work should involve real-world testing in higher-quality simulators, as well as trials involving a more diverse demographic.

“Our findings support the idea that trust in driverless cars can be built not just through more information, but the right information,” Dr Walsh says.

Osaka, Japan – Developmentally expressed genes play a fundamental role in the formation of a wide range of organs. The Y chromosome-located mammalian sex-determining gene Sry, required for the formation of testis, is activated only within a narrow time window during embryogenesis. However, the processes behind the activation of Sry remain uncertain.

Now, in a recent publication from Nature, a team from The University of Osaka has discovered that iron plays a crucial role in male mammalian sex development.

The Sry gene directs sexually undifferentiated gonads to differentiate into testes rather than ovaries. The Sry gene is initially inactive because of a modification added to DNA-wrapping proteins called histone methylation. In males, a protein called KDM3A is responsible for removing this histone methylation, allowing the Sry gene to become active.

“We already knew that KDM3A requires iron for its enzymatic activity,” says lead author, Naoki Okashita. “Therefore, we wanted to investigate the extent and nature of iron metabolism and histone demethylation in sex determination.”

The researchers established mice lacking Tfrc, a gene crucial for cellular iron incorporation. Loss of Tfrc prevented the removal of the histone methylation, leading to reduced Sry expression. When inspecting the genitals of these mice, it was found that some XY mice developed as female, despite being genetically male.

The team also established an organ culture system for gonadal cells in which they could manipulate the levels of available iron. This confirmed that iron deficiency reduces the activity of KDM3A and activation of Sry. Therefore, the reduced Sry suppression under iron-deficient conditions was caused by the failure of KDM3A to remove histone methylation.

Perhaps most significantly, they then showed that maternal iron deficiency – whether induced by diet or by pharmacological intervention – could lead to altered histone methylation of the Sry gene because of reduced KDM3A activity. Some population of XY offspring derived from iron-deficient pregnant females were shown to undergo male-to-female sex reversal, potentially due to the impaired Sry activation.

“Our findings indicate that iron deficiency leads to disorders of male development, at least in mice. Our study emphasizes the importance of maintaining maternal iron levels,” explains senior author, Makoto Tachibana.

It is known that in humans, Fanconi anemia and Diamond–Blackfan anemia are risk factors for disorders of development. Understanding how iron supports embryonic development underscores the importance of maternal iron intake for the healthy development of human embryos.

The efficient conversion of carbon dioxide (CO2) into valuable hydrocarbons is a critical step towards sustainable energy solutions. Now, researchers from the School of Environmental Science and Engineering at Shanghai Jiao Tong University, led by Professor Daoping He and Professor Fangming Jin, have developed a novel hydrothermal CO2 methanation process using a non-precious Co@ZnO catalyst. This innovative approach achieves a remarkable 100% conversion of CO2 to methane (CH4) under optimized conditions, offering a sustainable and efficient solution for CO2 utilization.

Why This Research Matters

  • High Efficiency: The Co@ZnO catalyst enables a complete conversion of CO2 to CH4, with no detectable by-products such as CO or higher hydrocarbons.
  • Non-Precious Metals: The use of cobalt (Co) and zinc (Zn) as catalyst components avoids the need for expensive noble metals, making the process more cost-effective.
  • Sustainable Energy: This method leverages solar energy and hydrothermal conditions, providing a green pathway for CO2 reduction and methane production.

Innovative Design and Features

  • Co@ZnO Catalyst: The catalyst features a unique structure where honeycomb-like ZnO nanosheets grow in situ on the Co surface. This structure stabilizes Co in its metallic state and enhances its catalytic activity.
  • Hydrothermal Process: The reaction is conducted in a hydrothermal environment, where Zn is oxidized to produce hydrogen, which then reduces CO2 to formic acid and ultimately to CH4.
  • Stable and Selective: The Co@ZnO catalyst maintains its activity over multiple cycles, with no significant leaching of Co, ensuring long-term stability and high selectivity for CH4 production.

Experimental and Practical Validation

  • Reaction Mechanism: In situ hydrothermal Fourier Transform Infrared (FTIR) spectroscopy confirms that formic acid is an intermediate in the CO2 methanation process. The Co@ZnO catalyst effectively converts formic acid to CH4 without forming CO.
  • Optimization: The study identifies optimal conditions for maximum CH4 yield, including reaction temperature, duration, and the ratio of Zn to Co.
  • Energy Efficiency: The process is energetically favorable, with the energy released from the reaction compensating for the energy input required to heat the reactants after just three moles of reaction.

Future Outlook

This groundbreaking work presents a simple, sustainable, and highly efficient approach for CO2 methanation. By using abundant and non-precious metals, this method offers significant potential for practical applications in CO2 utilization and sustainable energy production. Further research could explore the scalability and integration of this process with renewable energy systems.
