It’s a similar story for Wells Fargo, which was on the hook for $460.9 million worth of oil and natural gas derivatives for companies including Carrizo Oil & Gas Inc., Pioneer, Antero, Concho and PDC, according to regulatory filings.

These aren’t, of course, the kind of figures that would trigger any sort of systemic-risk concerns. Commodities are generally smaller parts of banks’ businesses compared with lending and underwriting, and banks hedge their oil-price risk.

New York-based JPMorgan had $2.57 trillion in assets at the end of last year compared with net liabilities for commodity derivatives of $2.3 billion, not including cash from settled trades and physical commodity assets, according to regulatory filings. San Francisco-based Wells Fargo had $1.69 trillion in total assets compared with net commodity liabilities of $241 million.

Still, $26 billion is $26 billion.

U.S. oil companies already netted at least $2.4 billion in the fourth quarter of 2014 on their hedges, according to data compiled on 57 U.S. companies in the Bloomberg Intelligence index.

Oil companies would rather be losing money on the trades and making money selling crude at higher prices, Kilduff said.

“It’s like homeowners’ insurance,” he said. “You don’t buy it hoping the house burns down.”

Offset Risk

The $26 billion of protection won’t last forever. Most hedging contracts expire this year, according to company reports. Buying new insurance today means locking in prices below $60 a barrel. The alternative is following Hamm’s example and having no cushion if crude keeps falling.
