Welcome To The Currency War, Part 18: Dollar Soars, Economy Disappoints

 | Mar 15, 2015 02:42AM ET

The point of competitive devaluation, aka currency war, is that a cheaper currency gives a country several advantages over its trading partners, leading to better growth and generally happier voters. The trading partners, meanwhile, get the ugly mirror image — slowing growth and disgruntled citizens — so they eventually respond in kind, with devaluations of their own. If nothing happens to stop the war, everyone’s currency ends up being worth a lot less and a whole generation of savers is partially wiped out.

In the current skirmish, Europe is crushing the US, which is to say the dollar is soaring against the euro. So if the script holds, the US should be suffering. And — despite all the breathless reports of plentiful jobs and plunging unemployment — the recent numbers do paint a picture of a country hobbled by a too-strong currency. From Bloomberg this morning:

h2 Surprise: U.S. Economic Data Have Been the World’s Most Disappointing /h2 It’s not only the just-released University of Michigan consumer confidence report and February retail sales on Thursday that surprised economists and investors with another dose of underwhelming news. Overall, U.S. economic data have been falling short of prognosticators’ expectations by the most in six years.

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.
