Greg Ip points out that the stronger dollar in 2018 is creating serious problems for Argentina, and will have an effect on Turkey, Indonesia and other developing countries. Dollarization hurts because it increases debt as debt servicing becomes costlier with dollar denominated debt and imports denominated in dollars become costlier.

The dollar has increased in importance in the global economy. This is why the economic growth has suffered in developing countries in 2018. It is also why president Trump believes he can cut off Iran from the U.S. banking system to increase chance of new negotiations to fix flaws in the Iran nuclear deal, says Ip.  

Argentina has seen internal problems compounded by the rising dollar causing the peso to drop by 17% so far in 2018. 88% of Argentina's imports are denominated in dollars. A rising dollar means it costs more in pesos for imports. Argentina's different levels of government have $98 billion in dollar denominated debt, and private sector has an additional $68 billion, the total being a third of its GDP. A decline in the peso means this is harder to pay off.

About 40% of world trade, according to Harvard economist Gita Gopinath, is invoiced in U.S. dollars, four times U.S. share of world trade, and developing countries together owe $2 trillion in dollar denominated debt according to BIS. This makes it harder for developing countries such as Indonesia, Turkey, India, Argentina, Brazil, as they now face rising oil prices in combination with a rising dollar. In Argentina a poor crop for soyabeans and other agricultural exports in 2018 creates additional woes.
