Brent crude oil prices came under pressure on Tuesday as diplomatic progress in the Middle East reduced the perceived risk of supply disruptions, OCBC strategists said. The shift follows heightened oil-market volatility, when supply-side risks pushed prices higher, and reflects traders reassessing the likelihood of disruptions. OCBC did not provide specific price targets but said diplomatic efforts were weighing on sentiment. Further breakthroughs could cap price gains, although negotiations remain fluid and prices could rebound quickly if talks fail. Investors are watching for official confirmations and production-policy responses from major exporters. Lower crude prices could eventually provide modest relief at the pump, while squeezing producer revenues and oil-dependent national budgets; retail fuel prices also depend on refining margins and local taxes.
