Oil: Citi explains why prices haven’t risen even further, for now

Citigroup (Citi) research note explains why oil prices have not climbed further despite what looks like a paper oversupply. The bank points to Kazakhstan production outages, severe cold-related disruptions in the U.S. and Chinese stockpiling as forces that have supported prices, while other factors capped upside.

Citi’s analysts estimate the market shows roughly a 2 million barrels-per-day oversupply on paper, which would normally imply much lower prices. Yet field outages such as the Tengiz incident and winter storm-related curbs—at times reducing U.S. output by about 1.5 million bpd—along with tightening measures on Russian oil purchases, have tightened available supply. At the same time, intermittent releases from strategic reserves and weakening demand indicators have limited further rallies.

For markets, those dynamics have translated into pronounced short-term volatility: geopolitical headlines and supply disruptions have pushed Brent and WTI higher in spurts, while inventory prints and signs of demand weakness have acted as brakes. Bloomberg coverage highlights Citigroup’s warning that uncertainty around U.S.-Iran talks and Hürmüz Boğazı access will keep prices “moving around like crazy” until clarity emerges.

In a broader context Citi has updated its scenarios to reflect the risk that prolonged Hürmüz disruption could lift Brent substantially; under a bull case the bank assigns material probabilities to substantially higher price paths if flows remain impaired. This underscores that the oil market is now pricing not just barrels but the cost of normalization and transport risk.

Analysts expect elevated headline-driven volatility to persist in the near term, with the medium-term direction hinging on inventory trends, Chinese import behavior and OPEC+ responses. Citi’s scenario analysis implies wide possible outcomes—rapid price reversion if supply normalizes, or deeper upside if disruptions prove persistent—so market participants should monitor strategic reserve movements, shipping flows through Hürmüz and official production updates.
