The Bloomberg ECO U.S. Surprise Index, which measures whether data beat or miss forecasts, fell to the lowest since 2009, when the nation was in the deepest recession since the Great Depression.
There's been one notable exception to the gloom, and it's a big one: payrolls. The economy added 295,000 jobs in February and 1.3 million over four months, a reflection of a healthier labor market in which the unemployment rate has fallen to the lowest in almost seven years.
This month alone, personal income and spending, manufacturing as measured by the Institute for Supply Management, auto sales, factory orders, and retail sales have all come in a bit weak.
Citigroup keeps economic surprise indexes for the world, and its scoreboard shows the U.S. is most disappointing relative to consensus forecasts, with Latin America and Canada next, as of March 12. Emerging markets were supposed to be hurt by falling oil prices but are now delivering positive surprises. U.S. policymakers frequently talk about weakness in Europe and China, though both are exceeding expectations.
And there's one rub. The surprise shortfall in the U.S. doesn't necessarily mean the world's largest economy is in dire straights. It's just falling short of some perhaps overly elevated expectations.
Where are the data beating economists' forecasts most consistently? Sweden.
Jack Ablin, chief investment officer of BMO Private Bank in Chicago, said he pays attention to the surprise indexes as a way to gauge when a particular national economy may be turning and looks for good value in equities.
"It is an early indication of a momentum shift," he said, adding that he's been raising the amount of money put into international stocks. While Ablin expects moderate U.S. growth, he said a strong U.S. dollar has the potential to dampen the expansion.
Federal Reserve Chair Janet Yellen gave no hint of concern in recent congressional testimony, where she cited an "overall improvement in the U.S. economy and the U.S. economic outlook," boosted by lower oil prices.
The data slump may give the Federal Open Market Committee reason to wait before raising rates, said Jonathan Wright, a professor at Johns Hopkins University in Baltimore who worked at the Fed’s division of monetary affairs from 2004 until 2008.
First-quarter U.S. growth forecasts continue to be cut, and like last year, weather is getting a share of the blame.
JPMorgan Chase's Michael Feroli cut his forecast to 2 percent from 2.5 percent on March 6. Barclays Capital has reduced its estimate to 1.5 percent as of March 12. Macroeconomic Advisers' tracking forecast was lowered to 1.7 percent on March 12.
