Exchange rates react immediately to the threat of tariffs
Exchange rates are more than just abstract numbers. They determine the value of a Mexican peso, the cost of a German car in the U.S. and whether an Argentine farmer can repay his debts. Jantke de Boer, junior professor of international monetary macroeconomics at Ruhr University Bochum, has examined how expectations of future protectionist measures influence exchange rates.
Exchange rates shift rapidly in response to threats of tariffs, according to research from Ruhr University Bochum. Prof. Jantke de Boer found that expectations of future protectionist measures, even before they are implemented, immediately influence exchange rates across the globe. Financial markets respond to these anticipations before any political decisions are finalized.
Emerging markets, particularly those heavily dependent on U.S. exports, are especially vulnerable to such currency fluctuations. Countries like Mexico, with a peso weakened by protectionist announcements, experience higher import costs from the U.S., impacting industries reliant on machinery imports. Liquidity in financial markets, such as Brazil's, and foreign exchange reserves help alleviate these impacts for some countries.
The study, published in Emerging Markets Review, highlights the close relationship between economics and policy, suggesting that while protectionist measures may offer short-term benefits, they often lead to trade conflicts and higher prices in the long run.
