IIRC, the late '70s/early '80s is the only time in the modern era that they've been close. You'd be hard-pressed to average 6-8% bank savings rate in any normal period. With stagflation...somehow I doubt it, although that happens to be when it appeared last time. However, the Fed rate is doing much different things these days than it did back then.
I don't have the statistical or financial/accounting acumen to check your assumptions or math, but if they're correct, and it is indeed a 6-8% guaranteed annual return over 15 years, I'd take it and run. |
