But if the fed decides to buy the long end as part of an "anti deflation" strategy, I wouldn't hold my breath for yields to reflect reality. Instead, suspect that there will be a return of 'risk premia' into the market.
I've been long bonds overall (in the retirement portfolio) and have kicked myself for not buying the long bond at 5.20 yield last summer. Hedged with appropriate inflationary instruments but could see both appreciating simultaneously. Or, perhaps, the reverse. Who knows. But I'm buying more 30yr at 5.25, insane as it may sound. If we're going into a true hyperinflation, its as bad as leaving it in cash anyway.
