The dollar soars by a record amount versus the euro and the yen in 2014. And economists predict strong growth in 2015. Really? If a country can have a rapidly-appreciating currency with all the benefits that that confers, and strong economic growth with all the obvious advantages that that confers, why wouldn’t everyone be going for powerhouse currencies?

Because the two things, a strong currency and accelerating growth, tend to be mutually exclusive in the short run, with a strong currency acting like rising interest rates, slowing growth and making debts harder to service.

So it shouldn’t be a surprise that the latest batch of US numbers are somewhere between disappointing and catastrophic. First-quarter GDP was flat and is about to be revised negative. Retail sales were flat in April, the first month of the second quarter, with business inventories and import prices pointing in the same grind-to-a-halt direction.

The US is now looking at zero growth for the entire first half of 2015. Six years into a recovery, with record low interest rates and a recent doubling of government debt, that’s a bit of a dilemma. Especially given the Fed’s threat to raise interest rates in the next few months.

Rates clearly are not going to be raised, at least not on purpose. On the contrary, slow growth always and everywhere leads panicked governments to break out the stimulus. And the dollar is reacting to this prospect exactly as one would expect, by falling like a stone in the past month.

Gold, meanwhile, is acting like the reciprocal of the dollar, adding $30 an ounce in the past two days.

At the risk of excess repetition, the US is obviously losing the currency war and will soon be forced into a new offensive. Negative interest rates, here we come.
