The dollar weakened against major currencies as former President Trump's renewed threats toward Greenland revived market anxieties about geopolitical risks. Euro and sterling both advanced, with traders weighing the potential economic fallout from renewed American tariff threats against traditional safe-haven flows.

Currency markets are reacting to what investors perceive as a return to unpredictable U.S. foreign policy. The Greenland comments echo Trump's 2019 bid to purchase the territory, which had previously unsettled allies. Markets now face renewed uncertainty about trade relationships and geopolitical stability.

The dollar's decline reflects broader concerns about America's global standing. Investors are assessing how such rhetoric could affect international cooperation and trade agreements. This comes as central banks worldwide navigate divergent monetary policies and persistent inflation pressures.

Looking ahead, currency traders will monitor U.S. political developments closely. The market's reaction suggests growing sensitivity to geopolitical headlines, potentially creating volatility in foreign exchange markets. Investors may seek hedges against escalating trade tensions.
