WSJ Factual Error

From the top story in today’s Wall Street Journal:

At one point during the day, investors were willing to pay more for one-month Treasurys than they could expect to get back when the bonds matured....That’s never happened before.

Actually it has happened before, not in the easily available data, but it has happened – in 1938 (and apparently several other times between 1935 and 1941).

My only source is a talk by Paul Samuelson, for which I cannot even point to a transcript, but I’m confident that primary sources will bear me out. I’m too lazy to go check old copies of The Wall Street Journal on microfilm, but take my word for it.

It’s actually pretty obvious if you look at the monthly data from the Fed. For example, in February 1941, the average yield on 3-month T-bills was 0.03 percent. Considering how the yield fluctuates from day to day and from hour to hour, it’s impossible to believe that it was not negative at certain points during that month. (Technically the Journal was referring to one-month bills, but it’s a safe assumption that, if 3-month bills were selling above maturity value, so were one-month bills for at least part of the time.)


UPDATE: Paul Krugman makes the same claim (hat tip: anonymous commenter)....and I continue to believe it is wrong. I'm not sure his claim is independent: he may have gotten his information from the Journal, or they may have gotten it from the same source, which I hope they will cite so we can follow it up and judge its reliability.

UPDATE2: Reuters and the AP, both citing Los Angeles-based Global Financial Data, report that the last time the 3-month T-bill was at or below zero was January 1940. (Could it merely have been "at" zero? It seems unlikely that the bid would have stopped at exactly zero.) Another AP report says that demand sent "the yield on the 3-month Treasury bill briefly into negative territory for the first time since 1940." Friedman and Jacobson, in A Monetary History of the United States, 1867-1960, say in a footnote that "yields on Treasury bills were occasionally negative in 1940." (Apparently my "obvious" conclusion about 1941 was not correct, buy my main point stands.)
