Not sure that’s correct either.. anywho.. more issues being the reserve currency..

https://en.wikipedia.org/wiki/Triffin_dilemma

The Triffin dilemma is usually cited to articulate the problems with the role of the U.S. dollar as the reserve currency under the worldwide Bretton Woods system established in 1944. John Maynard Keynes had anticipated this difficulty and had advocated the use of a global reserve currency called 'Bancor'. Historically, the IMF's SDRs have been the closest thing to the proposed Bancor but they have not been adopted widely enough to replace the dollar as the global reserve currency.

In the wake of the 2007–2008 financial crisis, the governor of the People's Bank of China named the reserve currency status of the US dollar as a contributing factor to global savings and investment imbalances that led to the crisis. As such, the Triffin Dilemma is related to the Global Savings Glut hypothesis because the dollar's reserve currency role exacerbates the U.S. current account deficit due to heightened demand for dollars.
