Weak currency = it becomes cheaper for other countries to purchase from you. It becomes more expensive for you to purchase from other countries. Strong currency = you can buy cheaper from the rest of the world, but you're more costly for the rest of the world. A balanced economy is good. The US have a negative current account balance --> the buy more than they sell to the rest of the world. The US$ has to weaken to balance it. Germany is the opposite, so German currency should become stronger because the current account balance is extremely positive. But it can't because Germany shares a currency with other countries. Oh, shit, Greece uses the same currency. Wtf, this shit can't work. 2015: "Oops"
