真实原文：The Federal Reserve announced today that all 23 U.S. banks participating in its annual stress test have passed, showing that they would be able to maintain minimum capital levels and continue lending in a severe economic downturn. Although the banks were projected to lose $541 billion in the test, they still met the required capital requirements, clearing the way for increased dividends and share buybacks. The tested banks included major players such as JPMorgan Chase and Citigroup, international banks with large U.S. operations, as well as the largest regional banks including PNC and Truist. However, smaller banks were exempt from the test, so passing the stress test does not guarantee their safety as in previous years. It is expected that regulatory scrutiny will tighten on regional banks in the coming months, and international standards may also increase capital requirements for large U.S. banks. Randal Quarles, the Vice Chairman for Supervision at the Federal Reserve, stated, "Today's results confirm that the banking system remains strong and resilient. But stress testing is only one way to measure this strength. Efforts should continue to ensure that banks can withstand a range of economic scenarios, market shocks, and other pressures."
