If our Fed took us back to 15%+ 30Y yield of the Volcker era 1980s, I would back up the truck and dump everything I own into it.
(This would likely also bankrupt the US with its current debt obligations, so maybe not the best of plans)
*Edit*
Even AI says this would be a catastrophe and unmanageable.
"The primary reason this strategy is no longer viable is the massive volume of leverage in the system. When Paul Volcker enacted his "shock" in 1979, the U.S. national debt was roughly $830 billion (about 30% of GDP). Today, the national debt stands at a staggering $38.6 trillion (well over 100% of GDP), completely altering the mechanics of monetary tightening."
