He’s saying that inflation will perpetuate negative real rates despite increasing bond yields as bond prices decline.

Yes, thanks. That wasn't written well. Bonds today have negative real interest rates and likely will going forward even as nominal rates rise. The only way this doesn't happen is if inflation drops quickly which seems very, very unlikely.

It doesn't. Bond prices going down will help close the gap between bond rates and inflation. When the Fed floods the market with its existing treasuries via QT, new treasuries will need to be issued at higher rates to compete.
