Unusually Large Oil Short Positions Placed Ahead of US–Iran Ceasefire Announcement

Investors placed unusually large short positions in crude oil just hours before news of a ceasefire between the United States and Iran was announced. According to Reuters, citing data from LSEG, on April 7 at 19:45 GMT traders sold a total of 8,600 Brent and WTI crude futures contracts. Later, around 22:30 GMT the same day, President Donald Trump walked back his earlier threat to destroy “an entire civilization” and announced a two-week ceasefire with Iran. Following the announcement, Brent crude fell more than 16 percent and WTI down about 13 percent, with prices dipping below $100 per barrel. The move suggests those who were short held substantial profits, though the traders’ identities could not be determined. Reuters notes that large bets on oil price direction are not uncommon, as they are means for hedging large physical oil positions. However, such positions are rarely executed in single large lots because traders typically place many smaller orders across multiple exchanges and require brokers to use algorithmic trading over hours to implement, avoiding sudden price swings. Large orders are especially atypical after market close (18:30 GMT, Monday–Friday). The $950 million short oil bet on April 7 echoes a similar action on March 23, when investors shorted approximately $500 million worth of oil futures just before Trump delayed an attack on Iran’s energy infrastructure. That decision shocked the market and sent prices down as much as 15%. In that session, WTI volume surged around 6:50 a.m., despite relatively quiet market conditions, and the S&P 500 e‑Mini futures volume also spiked as a large buy order hit the market. The timing is notable because it is a period when trading activity is typically subdued, making such large orders unusual. About 15–20 minutes later, at 7:05 a.m., Trump posted on Truth Social that the planned strikes on Iranian power and energy infrastructure would be halted. The oil price collapse and a surge in US stock futures followed, implying traders behind these moves captured substantial profits in a very short time. On March 7, roughly 6,200 Brent futures and 2,400 WTI futures contracts were sold at 19:45 GMT, representing about 1% of the day’s normal volume. Trading volume and market volatility have increased since the US–Iran conflict began. Over the three years prior to the conflict, daily Brent futures turnover averaged about 300,000 contracts. In the last four weeks, Brent futures’ average daily volume has more than doubled, with occasional days exceeding 1 million contracts (roughly 1 billion barrels) – a level not seen before.
