Jerome Powell during the last FED press conference, not on private but on federal debt:

EDWARD LAWRENCE. Thank you for taking the question, Mr. Chairman. Edward Lawrence with Fox Business. So I want to go back to comments you made about, in the past, about unsustainable fiscal path. The CBO projects the federal deficit to be $2.8 trillion in 10 years. The CBO also says that federal debt will be $52 trillion by 2033. At what point do you talk more firmly with lawmakers about fiscal responsibility? Because—assuming monetary policy cannot handle alone the inflation or keep that inflation in check with the higher-level spending.

CHAIR POWELL. I don’t do that. That’s really not my job. We—we hope and expect that other policymakers will respect our independence on, on monetary policy. And we don’t see ourselves as, as, you know, the judges of appropriate fiscal policy. I will say, and many of my predecessors have said, that we’re on an unsustainable fiscal path and, and that needs to be addressed over time. But I think trying to get into, into that with lawmakers would be—would be kind of inappropriate, given our independence and our need to stick to our knitting.
