But it's not just the euro that the dollar is rising against. It's pretty much every currency in the world. That's because the U.S. economy is doing well enough that the Federal Reserve is getting ready to raise rates, and the rest of the world is slowing down enough that it's cutting them. And that's not hyperbole. The not-so-short list of countries that have eased monetary policy the past few months includes Australia, Canada, Chile, China, Denmark, Egypt, India, Indonesia, Israel, Peru, Poland, Russia, Singapore, South Korea, Sweden, Switzerland, Thailand, Turkey, and, above all, the eurozone now that it's buying bonds with newly-printed money—aka quantitative easing—which Japan has also been, and still is, doing itself. The result is that investors can get better returns in the U.S. than they can in a lot of other places—would you rather buy a U.S. 10-year bond that pays 2.05 percent or a German one that pays 0.28 percent?—so that's where they're moving their money, and, in the process, pushing up the value of the dollar.
