"The funded status of the 100 largest corporate defined benefit pension plans decreased by $25 billion during July ... Pension liabilities rose due to a decrease in the benchmark corporate bond interest rates used to value those liabilities. As of July 31, the funded ratio dropped to 95.8%, down from 97.1% at the end of June. The current funded ratio is still ahead of the funded ratio of 90.3% seen at the start of 2021."
