NEW YORK: US shale producers are locking in prices for their production as much as three years into the future in a sign that strong domestic crude pricing is nearing a peak, according to market sources familiar with money flows. US crude prices for 2019 and 2020, based on an average of each year’s monthly contracts, have climbed this week above $68 and $64 a barrel, respectively, the highest levels in over three years. The rally comes even as front-month prices have dropped from the three and a half year highs touched during the summer. “Hedging activity has picked up considerably over recent weeks and this will continue to be the case as producers begin to frame budgets for next year,” said Michael Tran, commodity strategist at RBC Capital Markets, noting the rally in forward prices are encouraging the producer bets. Hedging can reduce risks associated with volatility in oil prices, acting as an insurance contract to lock in a future selling price and fix spending plans. Such longer-term bets signal US producers will continue to expand output, keeping a lid on prices, according to crude traders and brokers. The nation’s output this year has climbed above 10 million barrels per day (bpd), close to top producers Russia and Saudi Arabia. That output is forecast to grow next year by 840,000 bpd to average 11.5 million bpd. There was a large uptick in crude swap activity last week, with just shy of 8 million barrels changing hands in a day, an energy derivatives broker said, signaling strong hedging interest. Swaps are a type of contract that allow producers to lock in or fix the price they receive for their oil production. Almost 80 percent of the swap activity was split evenly between calendars 2020 and 2019, and the remaining 20 percent for this year, the broker said, adding that there was a small amount of calendar 2021 activity during the week. The market sources declined to say which oil companies were actively hedging in recent weeks. The move to hedge at these levels could prove risky for producers in a market where the price of oil for immediate delivery is higher than for later deliveries. Many US shale producers hedged second-quarter production at about $55 a barrel, which backfired as US crude climbed to more than $70 a barrel last quarter, the highest level since 2014. As a result, producers are using more “collars,” a financial instrument that provides price protection on the downside while allowing them to share in some of the upside if prices rally. “We’ve been building a lot of collar structures,” Christian Kendall, chief executive of Denbury Resources Inc. said last week, noting that the instruments will protect its production at about $60 a barrel and provide upside if oil rises to the high $70s per barrel. Denbury is nearly 50 percent hedged for 2019 and will add hedges to get to 60 percent to 70 percent of production, Kendall said.
