All-in TLT5/TMF?

- After Powel's hawkish tone, the US30Y yield has risen even further, and TLT even lower.

- It seems to me that the US30Y has an upper bound, right? Like it's kinda protected not to go above some level, like the Fed funds rate. Doesn't this make it a safety guard for TLT?

- Some analysts already call for dovish suprises next year.
