U.S. natural gas prices are sharply higher on Friday as traders react to uncertainty over the U.S.-Iran war. Settlement day positioning in the April futures contract and the rollover into May is also the source of upward volatility. In my opinion, traders are showing their biggest response to the Middle East conflict because there are signs the war will last longer than promised. Thursday’s bullish inventory surprise in the government’s weekly inventory report is also helping to underpin prices.
