US, Denmark Reach Greenland Security Deal; NATO Shares Arctic Responsibility

Shares of US-listed companies exposed to Greenland surged on Monday after the US and Denmark reached a security deal on the Arctic territory.

Greenland Energy soared 159%, Greenland Mines was up over 200%, and Critical Metals Corp rose nearly 37%. The agreement, expected to be signed during the United Nations General Assembly this week, will see the US, Denmark, and Greenland develop a military presence on the territory. It will also block Washington's adversaries from building their own bases there.

Danish Foreign Minister Lars Lokke Rasmussen stated on Sunday that the deal will put Arctic security under NATO's watch, rather than leaving it solely to Washington and Copenhagen. A NATO spokesperson welcomed the agreement on Saturday, stating it would help advance security, stability and cooperation in this vital region. President Donald Trump announced the deal via Truth Social on Friday, stating the US would "FOREVER have the complete ability to do what is necessary in Greenland in order to secure and defend the security of Greenland, and the United States of America."

Trump said the agreement would come at no cost to the US and that Washington would immediately begin the process of developing a large Military presence. Danish and Greenlandic officials sought to reassure citizens over the weekend that the deal would respect the island's right to self-determination and the sovereignty of the Danish kingdom. Greenland's Prime Minister Jens-Frederik Nielsen said the agreement recognizes Greenland's interests and its place in international cooperation.

The deal follows several months of President Trump's threats to annex the self-governing Danish territory, with the president insisting Greenland is critical to US national security. His threats, which peaked in January, triggered a diplomatic crisis within NATO and pushed Denmark and Greenland into negotiations with Washington. Washington's strategic interest in Greenland dates back to World War Two. In 1941, the US signed a deal with Danish envoy Henrik Kauffmann, who acted without authority from his country, then under German occupation. Key details of the agreement have not yet been made public.
