Open USD is a new stablecoin system. Stablecoin policies should increase demand for US Treasuries. This video, about US debt, claims the US inflated away World War II debt via financial repression:
As I recall, after World War II, the national debt did not grow much in nominal terms for decades while GDP continued to grow, reducing debt/GDP ratio. These references show the Fed balance sheet and analysis of whether or not the economic growth reduced debt/GDP:
The paper seems to be an effort to model the counterfactual narrative. Did the private sector economy drive GDP growth and/or inflation? Or did the government have policies of financial repression that explain the reduced federal debt/GDP? Some mix of both stories?
