By now you should already know that Warren Buffett is no fan of US Treasury bonds, or really any other asset that’s so explicitly tied to the US dollar, which has lost a ton of value during his career as an investor.In his new shareholder letter, he explains his disgust towards Treasuries. As he sees it, taxes and inflation are eating you alive, and today they should come with a warning label.
Even in the U.S., where the wish for a stable currency is strong, the dollar has fallen a staggering 86% in value since 1965, when I took over management of Berkshire. It takes no less than $7 today to buy what $1 did at that time. Consequently, a tax-free institution would have needed 4.3% interest annually from bond investments over that period to simply maintain its purchasing power. Its managers would have been kidding themselves if they thought of any portion of that interest as “income.”
For tax-paying investors like you and me, the picture has been far worse. During the same 47-year period, continuous rolling of U.S. Treasury bills produced 5.7% annually. That sounds satisfactory. But if an individual investor paid personal income taxes at a rate averaging 25%, this 5.7% return would have yielded nothing in the way of real income.This investor’s visible income tax would have stripped him of 1.4 points of the stated yield, and the invisible inflation tax would have devoured the remaining 4.3 points.
It’s noteworthy that the implicit inflation “tax” was more than triple the explicit income tax that our investor probably thought of as his main burden. “In God We Trust” may be imprinted on our currency, but the hand that activates our government’s printing press has been all too human.
High interest rates, of course, can compensate purchasers for the inflation risk they face with currency-based investments – and indeed, rates in the early 1980s did that job nicely. Current rates, however, do not come close to offsetting the purchasing-power risk that investors assume. Right now bonds should come with a warning label.
