Iran insists on concrete guarantees before reaching any agreement with the US, as per a statement from the Iranian Foreign Ministry. This stance is communicated before an upcoming meeting in Istanbul with the E3 – Britain, France, and Germany – to prepare for potential US-Iran talks.

The primary goal of these discussions is for Iran to cease its nuclear activities, a key demand from the US. The oil market is closely monitoring the situation, anticipating a potential increase in Iranian oil supply if agreements are reached.

Crude Oil Inventory Report

In related news, a private survey shows a build in headline crude oil inventory contrary to the expected draw. Iranian Deputy Foreign Minister Abbas Araghchi addressed these issues in a conversation with Japanese media outlet NHK on Friday.

What’s been said so far, plainly put, is that Iran isn’t moving forward on any agreement with the US unless it’s backed by something firm, legally or otherwise. We know this comes just ahead of diplomatic sessions in Istanbul with Britain, France, and Germany—the so-called E3—which essentially serve as a planning table to map out what US-Iran negotiations might look like if they happen at all. From Iran’s view, verbal promises aren’t worth the paper they’re not written on; they’re after binding commitments.

The American demand remains what it has been: Iran must halt its nuclear enrichment far beyond commercial energy needs. This, if met, would presumably ease sanctions or at least open conversations around them. For the oil market, this creates a moving target. If diplomacy wins the day, and Iranian barrels return to global supply lines, that’s more oil on the table—potentially millions of barrels per day—putting downward pressure on prices.

Added to this is something more immediate. A private industry survey has shown that overall US crude oil inventories actually went up, whereas most traders were expecting a draw. These sorts of surprises tend to stir intraday pricing more than macro trends do. It’s not uncommon for traders using calendar spreads or options structures to reprice their position assumptions when inventory forecasts miss by this sort of margin. It does leave short-dated volatility screens looking enriched, at least over 1- to 2-week timeframes. Premiums appear to be getting backed into near-term contracts.

Araghchi, when speaking with NHK, wasn’t giving the usual soft diplomatic lines. He made it fairly plain, not only maintaining Iran’s expectations but tying them to broader international efforts. He also appeared to frame the US position as inconsistent over time, likely as a nod to prior deal commitments and their abandonment. It suggests that any resolution, if one is reached at all, won’t emerge overnight. That ambiguity alone can drag on sentiment for those holding structured derivatives tethered to Brent or WTI pricing benchmarks.

Market Reaction and Strategy

Right now, we can say with certainty that implied volatility in the front-month crude contracts has reacted more sharply to inventory changes than diplomacy headlines. That said, if the Istanbul meetings produce even a baseline framework, the politicking might start to overtake the barrels again. Possibility of increased supply, even months out, begins to get priced in through longer-dated future spreads—especially along the 6- to 12-month curve, where open interest has started shifting.

As a group, our own models are beginning to flag dislocations between historical risk premiums and current market structure, notably in the back-end of the curve. Steepening or flattening there can open opportunities for leveraged roll strategies or even arbitrage across regional grades. There’s also a noticeable shift in positioning within the options market, especially around $75 strike calls expiring next quarter. That sort of activity tends to reflect growing sentiment that either supply will weigh on prices or that macro pressures will subdue long-risk.

We’re watching intraday reaction to unexpected inventory builds much more closely now, particularly how they interact with volatility surfaces. It informs us where short-term traders see risk actually playing out, versus positioning just for geopolitical noise. The materials quoted earlier set a tone—it’s hard, it’s conditional, and it’s not moving fast. Those waiting on clarity should plan for delay, not resolution.
