WASHINGTON — President Donald Trump reignited a dispute with Denmark and Greenland by insisting the United States must “own” the Arctic territory and by refusing to rule out force, jolting markets and rattling U.S. allies, Jan. 13, 2026.
The Trump Greenland push is framed by the White House as a national security move to deter Russia and China in the Arctic, but it is quickly spilling into finance and alliance politics — raising questions about how far Washington is willing to go and how Europe would respond.
Trump Greenland: markets move first
In the most immediate reaction, investors sought shelter. Gold hit a fresh record after climbing more than 4% last week, and Europe’s aerospace and defense sector logged its biggest weekly jump in more than five years, according to a Reuters analysis of the surge in gold and European defense shares. Germany’s Rheinmetall rose 19% last week and Sweden’s Saab surged 22%, the analysis said, underscoring how quickly the Trump Greenland storyline has become a tradable geopolitical risk.
Strategists interviewed by Reuters cautioned that “big-impact, low-probability” outcomes are notoriously hard to price — yet the direction of travel is clear: more perceived fracture risk inside NATO has translated into higher demand for hard hedges and defense exposure.
Trump Greenland: NATO nerves and EU red lines
European officials have responded with unusually blunt warnings. EU Defense Commissioner Andrius Kubilius said a U.S. military takeover of Greenland would mean “the end of NATO,” and noted the EU’s mutual-assistance clause could come into play if Denmark faced aggression, according to Reuters reporting from a security conference in Sweden.
Greenland’s government, meanwhile, has tried to steer the debate back into alliance channels, saying the territory’s defense “must therefore be through NATO” and rejecting any takeover outright, Reuters reported from Stockholm. The statements highlight a core tension: Trump Greenland rhetoric may be aimed at projecting strength, but it also tests the alliance’s foundational premise that members do not threaten one another.
How the Trump Greenland pressure campaign escalated
On Jan. 6, the White House said Trump and his team were discussing a range of options to acquire Greenland and that using the U.S. military was “always an option” for the commander in chief, Reuters reported from Washington. That language, even if framed as leverage, is the kind of signal that allies — and traders — interpret as a meaningful shift in risk.
What’s old is new again in Trump Greenland
The current standoff echoes Trump’s first-term flirtation with acquiring the island. In August 2019, Greenland’s leadership signaled it was “open for business but not for sale,” a message captured in a Reuters report on the original purchase talk. The following year, Washington moved to deepen ties with a $12.1 million economic aid package aimed at countering Chinese and Russian influence in the Arctic, Reuters reported in April 2020.
Today, Trump Greenland language is again forcing Europe to weigh contingency plans — and forcing markets to reprice the once-unthinkable: a crisis inside NATO itself.
