Banking and Finance Law Daily Wrap Up, FINANCIAL STABILITY—Warren urges Fed to include oil price shocks in 2026 bank stress test scenarios, (May 21, 2026)

“If stress tests do not force banks to prepare to respond to worst-case scenarios, they leave the banking system –and the public–unprepared in the face of economic crises,” the Senator stated.

The Federal Reserve Board should immediately update its June 2026 bank stress testing scenarios to include a 140 percent jump in oil prices because of the ongoing war with Iran and notify the public of the revisions by June 2, 2026, wrote Senator Elizabeth Warren (D-Mass.), Ranking Member of the Senate Banking Committee, in a letter to Michelle Bowman, Fed Vice Chair for Supervision. “It is not too late to do so, as the Fed has only begun to calculate the results, which will not be published until the end of June,” the Senator added in the letter dated May 19, 2026.

“(S)tress tests must be forward-looking evaluations of how big banks would perform in a hypothetical severely adverse economic scenario to ensure they are resilient and can continue to serve households and businesses even in a severe recession,” the Senator reiterated. “If stress tests do not force banks to prepare to respond to worst-case scenarios, they leave the banking system –and the public–unprepared in the face of economic crises.”

Unfortunate Timing. In February 2026, the Fed, under pressure from the banking industry, weakened the severity of final stress-test scenarios, including assumptions for oil price increases, Senator Warren wrote. The Fed stated that “the shock to oil prices would be reduced from 77%, as proposed, to 27.9%, so that the joint calibration of the oil price and credit spread shocks (350 bps for BBB-rated bonds) would be better supported by historical experience.”

Just weeks later, the Fed’s failure of imagination was on display, the Senator stated, as the war with Iran, which began on Feb. 28, 2026, disrupted global energy markets and pushed oil prices higher. And a large, global fund manager is now “examining a scenario where Brent crude rockets to $180 a barrel, causing surging inflation and recessions in a host of European and Asian countries,” Senator Warren wrote, citing a May 17, 2026, Financial Times article. That would represent a more than 140% increase in oil prices relative to the start of the war, she stressed.

The Fed appears to have “inadvertently dialed down an historic source of systemic stress in its 2026 economic scenarios right before the war unfolded,” she observed. It is also essential for the Fed to explain why it severely weakened the oil price shock and other aspects of the stress-testing scenarios, considering pressure from the banking industry. Unfortunately, even if the Fed did adjust its stress tests, “this fix would only marginally strengthen the stress-testing framework, which is being drastically weakened by the Trump administration in ways that would water down additional stress-test models and make it easier for big banks to game the tests,” the Senator concluded.
