Federal Reserve Gov. Christopher Waller said the central bank should lower its target interest rate now and execute a series of cuts in months ahead.

"Fed watchers will be parsing Powell's comments for signs that a 50bp rate cut is on the table for September," noted Lauren Saidel-Baker, an economist with ITR Economics. "However, the notoriously tight-lipped chair is unlikely to confirm this, making a 25bp cut the most likely outcome."

The Federal Reserve chair said there is a consensus within the central bank's board of governors for reproposing its capital rules, but notes that other agencies have not yet signed off on this approach.

The central bank also noted that the banking system is sound but faces several challenges. The report precedes Federal Reserve Chair Jerome Powell's upcoming appearances on Capitol Hill.

Federal Reserve Chair Jerome Powell brushed away concerns that a second Trump presidency could imperil the central bank's independence.
