The winner of a currency race to the bottom is inevitably the biggest loser. From Daniel Lacalle at dlacalle.com:
The biggest mistake the Biden administration can make is to follow the siren calls of its competing economies to massively devalue the US Dollar, print endlessly and go full-MMT (Modern Monetary Theory), which is not modern nor a theory. Destroying the currency’s purchasing power to finance bloated government spending has been used for centuries with the same final effect: Collapse of the economy.
After an unprecedented increase in debt and government spending, many countries face the almost inevitable prospect of more currency devaluations, which has triggered pre-emptive responses all around the world. A currency war?
What is a currency war? A currency war is a conflict between nations trying to artificially devalue their domestic currency in order to be more competitive internationally but also to hurt their opponents. Using the currency to make the other nations less competitive while at the same time weakening their power.
It is based on a myth. That devaluation helps competitiveness and that having a strong currency is negative. Devaluation is not a tool for exports, it is a tool for cronyism, and destroys the purchasing power of salaries and savings to benefit low productivity sectors and the government. It is a transfer of wealth from citizens to the government.
