With a guaranteed annuity growing at 2% year over year, it's your local inflation that you should be worried about.
If your annuity is denominated in USD, and your local currency differs, you should also worry about the currency conversion rate.
But, in the last decade, USD's relative worth has only grown compared to most major other currencies. A mercantillist US (tarrifs) will make foreign accessibility to USD harder, so I expect USD to further increase compared to other currencies.
