The Short Version
Oil markets were indeed volatile before March 24, 2026, but this was driven by the ongoing US-Israel-Iran military conflict, not by foreknowledge of Trump's diplomatic announcement. The IEA documented unusual trading volumes tied to broader geopolitical tensions, not to the specific "fruitful negotiations" statement. Multiple news outlets confirm the sharpest oil price moves occurred immediately after Trump's comments, consistent with a market reaction rather than pre-announcement positioning. No regulatory data confirms anomalous anticipatory trading.
