Watch Fed Chair Powell, ECB's Lagarde speak live at central bank policy forum

[The stream is slated to start at 9:30 a.m. ET. Please refresh the page if you do not see a player above at that time.]

Federal Reserve Chairman Jerome Powell joins a panel including his global counterparts Tuesday at a European Central Bank forum Tuesday.

Powell will join ECB President Christine Lagarde and Brazil Central Bank Governor Roberto Campos Neto at the ECB Forum on Central Banking in Sintra, Portugal. CNBC's Sara Eisen will moderate. The forum happens with investors closely watching how central bank policymakers will react to inflation dynamics around the world.

In the U.S., the Powell-led Fed has kept its main policy rate steady for the past year despite inflation rates well off their mid-2022 peaks. Lagarde's ECB enacted a quarter percentage point cut that took its rate down to 4.25%, while Neto's bank cut by a quarter point in May to take its primary rate down to 10.5%.

Traders largely expect the Fed to start cutting in September with another reduction by the end of the year and quarterly moves lower through at least September 2025. However, Fed officials in June indicated they expect just one reduction this year.
