Brent Crude Tops $90 as Iran-U.S. Deal Hopes Fade

Brent North Sea crude climbed above $90 per barrel on Tuesday for the first time in more than a week, driven by a convergence of pressures: the collapse of meaningful progress in Iran-U.S. nuclear talks, a deadly Houthi missile strike on a cargo vessel in the Bab el-Mandeb strait, and signals that Chinese independent refiners are preparing to increase purchases of Iranian crude.

The price of Brent, the main international oil benchmark, crossed the $90 threshold Tuesday morning, according to Middle East Eye, as traders priced in a reduced probability of a near-term diplomatic resolution that could return sanctioned Iranian barrels to open markets.

Talks at an Impasse

Diplomatic efforts between Washington and Tehran appeared to stall after U.S. President Donald Trump said he would seek compensation from Iran for casualties sustained during the conflict, according to Al Jazeera. Trump also asserted that the Strait of Hormuz remains open to commercial traffic — a claim Tehran has disputed at various points — while the compensation demand signals no imminent easing of sanctions pressure.

The compensation stance adds a new variable to negotiations already complicated by disputes over uranium enrichment levels, sanctions relief sequencing, and inspection protocols. A deal that unlocks Iran’s roughly three million barrels per day of production capacity would represent one of the largest single supply-side developments in the oil market in years. Until that prospect grows more credible, traders are keeping a risk premium in place.

The Trump administration’s specific demand for Iranian compensation is detailed in our report on stalled Iran peace deal negotiations.

Shipping Under Fire

Compounding supply anxiety, a Houthi missile struck a commercial vessel in the Bab el-Mandeb strait, killing two Pakistani crew members and one Indonesian national, according to the Jerusalem Post. The strait connects the Red Sea to the Gulf of Aden and is one of the world’s most critical maritime chokepoints for oil and liquefied natural gas shipments headed toward Europe and Asia.

Houthi attacks on Red Sea shipping have driven a sustained rerouting of tankers around the Cape of Good Hope, adding roughly two weeks of transit time and elevating shipping costs for the affected routes. While individual strikes no longer move spot prices the way early strikes did in 2024, a continuing pattern of disruption reinforces the risk premium already embedded in Brent and keeps insurance rates elevated for vessels transiting the area.

China Steps In

On the demand side, China’s independent refiners — commonly called “teapots” — are poised to increase purchases of Iranian crude this month, according to OilPrice. Crude stockpiles in Shandong province, the hub for China’s independent refining sector, have fallen to their lowest level in months, creating inventory pull that is expected to draw in more discounted Iranian barrels.

Chinese teapot refiners have been the primary buyers of Iranian crude operating outside formal sanctions channels, typically purchasing through intermediary traders and settling in yuan. A ramp-up in Chinese buying does not directly increase the supply available to Western markets, but it does narrow the effective discount at which Iranian crude trades, reducing the arbitrage that previously incentivized workarounds and shrinking the cushion that Iranian oil sales have provided to Tehran’s budget under sanctions.

What the $90 Level Signals

The $90 threshold carries psychological weight. It marks the level at which energy costs begin to weigh more visibly on airline margins, petrochemical feedstock prices, and consumer fuel costs in Europe and Asia. It also reintroduces political pressure in economies where central banks are trying to thread a path between cooling inflation and sustaining growth.

Traders are watching two near-term catalysts. First, any response from Tehran to Trump’s compensation demand — acceptance would suggest talks retain some momentum; rejection likely pushes Brent toward $92–$95 in the near term. Second, the weekly U.S. crude inventory report from the Energy Information Administration, due later this week, which will indicate whether domestic stockpiles are drawing at the rate implied by current refinery run rates.

Analysts tracking the broader energy picture are also monitoring the degree to which disruption of Russian oil infrastructure feeds into global supply calculations. Ukraine’s sustained drone campaign against Russian energy facilities has targeted production linked to federal revenue flows — a dimension covered in our earlier report on Ukraine’s strikes against Russian oil and missile production.

For now, the direction of travel in oil markets is being set in Tehran and Washington, and the signals coming out of both capitals on Tuesday pointed the same way: further from a deal, and higher at the pump.
