Europe possesses nearly $8 trillion in U.S. Treasuries, bonds, and equities, positioning it as a vital contributor to U.S. debt financing. According to NS3.AI, there are growing concerns that U.S. President Donald Trump's interest in Greenland could trigger a substantial sell-off by European investors. Such a move could destabilize U.S. assets and elevate political risk premiums. This scenario underscores the U.S.'s reliance on foreign investors to finance its deficits, potentially diminishing its influence in geopolitical matters such as the Greenland issue.
