After international oil prices experienced dramatic swings of sharp gains and steep losses, the latest policy direction from the Organization of the Petroleum Exporting Countries and its allies (OPEC+) has emerged. According to multiple sources familiar with the matter, OPEC+ is expected to pause further increases in production quotas after executing a final hike in September, keeping supply policy unchanged for the remainder of 2026 to allow more time to assess the profound impact of the U.S.-Iran war on the global oil supply chain.
This decision reflects the producer alliance's strategic thinking of waiting and watching in an extremely uncertain geopolitical environment. OPEC+ reportedly plans to hold an online meeting on August 2 to confirm the agreement for a daily production increase of 188,000 barrels in September. This hike will complete the final phase of gradually unwinding the voluntary production cuts of 1.65 million barrels per day that have been in place since 2023. However, informed delegates also stressed that the alliance has no intention of further adjusting production quotas before the end of this year.
Market observers note that there are multiple considerations behind OPEC+'s move. First, the U.S.-Iran war has forced several major Middle Eastern producers to significantly slash actual output and exports, rendering the nominal quota increases largely meaningless in substance. Iran has repeatedly attacked oil tankers transiting the Strait of Hormuz during the conflict, nearly disrupting traffic on this critical waterway that carries about one-fifth of the world's oil trade. The resulting crude supply losses are difficult to accurately estimate, making it even harder for OPEC+ to gauge the true supply-demand gap in the market.
Second, the producer alliance is facing internal pressure from a new round of production quota negotiations. OPEC+ is conducting a reassessment of each member country's maximum sustainable production capacity, work that will serve as the benchmark for formulating production guidelines for 2027. Some members, including Iraq, have already demanded higher individual production quotas citing their own capacity expansions. Maintaining the status quo has become the most pragmatic choice before consensus is reached among the various interests.
"There will be no more changes this year. We will maintain current production levels and wait for the new quota framework to take effect in January 2027," an unnamed source told media.
Meanwhile, international oil prices are undergoing a rare rapid evaporation of the "war premium." U.S. West Texas Intermediate (WTI) crude futures briefly plunged more than 8% during Monday's (July 27) session, touching $81.99 per barrel (approximately NT$2,700); Brent crude futures tumbled 9.5% to $87.55 per barrel (approximately NT$2,800), both marking their largest single-day declines in at least two months. This stands in stark contrast to the scene just last week when Brent briefly breached the $100 per barrel mark.
The direct trigger for this sell-off was U.S. President Donald Trump ordering a halt to a new round of airstrikes against Iran. According to reports, after 13 consecutive days of daily strike operations, Trump instructed the U.S. military to stop attacks on July 25, both to leave room for diplomatic negotiations and based on the assessment that existing airstrikes were approaching their effective limit without launching a large-scale ground military operation.
Market analysts generally believe this sell-off does not reflect deteriorating demand fundamentals but rather a rapid correction of previously extreme risk expectations. Before Trump announced the suspension of military action, traders had begun pricing in more pessimistic scenarios, including a complete blockage of Strait of Hormuz transit and more extensive attacks on regional energy facilities. As the diplomatic window reopened, this most extreme portion of the risk premium was quickly stripped from oil prices.
Analysts at Société Générale estimated in their latest report that if the U.S.-Iran conflict persists long-term without a clear resolution, each additional month could inject a risk premium of roughly $10 per barrel (approximately NT$300) into oil prices. This implies that while current market sentiment has eased somewhat, oil price volatility will remain elevated.
Notably, the violent swings in oil prices have begun to tug at the policy nerves of major global central banks. Just as oil prices were surging, the pace of U.S. inflation deceleration had been better than economists expected, but the re-acceleration of energy costs is altering market bets on the interest rate trajectory. According to data from CME Group, traders currently estimate a 36% probability that the U.S. Federal Reserve will resume rate hikes at its upcoming meeting. While rate hikes help curb inflation, they can also slow the economy by raising borrowing costs, leaving central banks caught in a more difficult balancing act between fighting inflation and supporting growth.
Looking ahead, the market's focus will remain intensely concentrated on whether U.S.-Iran diplomatic engagement can achieve substantive progress. Although the suspension of military action has increased the possibility of de-escalation, key variables including Red Sea shipping security, attacks by Yemen's Houthi rebels, Iran's nuclear issue, and the future navigability of the Strait of Hormuz all remain unresolved. Last week, a Saudi Arabian oil tanker was also attacked while using the Red Sea route to exit the Persian Gulf, highlighting that alternative routes face similar security threats.
Several Wall Street energy analysts caution that it is far too early to declare that Middle East risks are over. Should negotiations break down and military action re-escalate, the risk premium that the energy market has just released could be priced back into oil prices at an even faster pace, potentially ushering in a new round of violent turbulence in international crude markets.
