The financial writer Jim Grant, founder and editor of Grant's Interest Rate Observer, remarked in a Minneapolis speech this week that "it seems my business model needs freshening."
Now that governments or even car companies can borrow lots of money from investors at effectively zero rates of interest, he said, there are really no more interest rates left to observe.
That's the kind of dry remark typical of Grant, a contrarian and market historian likely all but unknown outside of financial circles.
What he had to say here, though, would have interested pretty much anyone trying to make his or her way in the world. That's because we have central bankers to thank for our zero-interest-rate environment, not the economy or the market for capital.
Just how much these well-intended central bankers have distorted asset prices — from what workers have stashed in stock mutual funds and hope to live on someday to the home they just refinanced — can't yet be reckoned.
But Grant called interest rates "the traffic signals of a market economy." And does anyone think it's perfectly safe to have all the traffic signals turn green at the same time?
As Grant stood at the podium Thursday night, he was well aware that he was addressing about 500 people from the Minnesota financial community at this CFA Society Minnesota annual dinner.
But even people with years of training and experience in financial markets may forget from day to day just how wacky the times are. So he sought to get them thinking, asking at the start of the speech just how many years it would take to cut your investment principal in half by continuously reinvesting at the minus-1 percent interest rate currently in Switzerland.
