Debt, gunboats, and Germany's informal imperial reach

If formal colonial disputes had largely been settled, how could Germany still threaten American interests in South America?

Germany could use lending, defaults, and military pressure to build de facto control without immediately creating a conventional colony, prompting countermeasures such as the Roosevelt Corollary.

Formal colonial borders did not end competition for influence. Cheap loans could create leverage over weaker states, and default could provide a pretext for blockade, troop intervention, or political control. British participation in debt-collection operations could recover British money while also keeping German ambitions within bounds. The Roosevelt Corollary appears here as an American answer to the danger that European powers might use unpaid debts to establish a foothold in the Western Hemisphere. The post-1945 West provides a comparison between annexation and influence because it is sometimes described as an American informal empire or sphere of influence despite the absence of direct control. Empire could therefore operate through finance, coercion, and spheres of influence without immediate legal annexation.
