Jon Lieber, head of Eurasia Group's coverage of political and policy developments in Washington, shares insights on US politics:

Why did President Biden renominate Jay Powell to be the chairman of the Fed, and who's his No.2, Lael Brainard?

Well, Powell by all accounts has done a pretty good job of managing the Fed through the coronavirus pandemic. He dusted off the playbook, first pioneered by Chairman Bernanke during the financial crisis, and he's largely continued the relatively easy monetary policy of his predecessor at the Fed, now Treasury Secretary, Janet Yellen. With inflation growing the way it has over the last several months, Biden now owns the policies of the Fed and is essentially endorsing what Powell has been doing and giving Powell the political cover to continue to keep rates low for longer, or as many people expect, raise them slightly over the next 12 months in order to fight inflation.
