Janet Yellen has stayed tight-lipped since the start of the Ukraine war — and some Washington insiders find the silence deafening.

As of Wednesday, the US Treasury Secretary hadn’t made a single TV appearance since the US began imposing sanctions on Russia over the Ukraine invasion. That’s a dramatic about-face from the fall, when Yellen was a fixture on networks like CNBC and CBS’s “Face the Nation,” touting the economic recovery despite nagging inflation and labor shortages.

“Treasury implements economic sanctions,” Monica Crowley, former Assistant Secretary of the Treasury, told The Post. “Public messaging — particularly by the Secretary — is absolutely critical. Because these sanctions have such huge consequences, she should be publicly explaining them and their impact. But she is nowhere to be seen.”
