The Return Reversal
This is the empirical core of the site. Despite being a net debtor, the United States has long earned more on its assets abroad than it pays foreigners on their U.S. holdings — the "exorbitant privilege." The chart below makes that concrete by computing an implied yield on each side of the external balance sheet.
How this is constructed
The implied yield on each side is a primary-income flow divided by the matching investment-position stock, reported in percent per year:
- Return on U.S. assets abroad = U.S. primary-income receipts ÷ U.S. assets abroad
(
IIPUSASSA). - Return foreigners earn on U.S. holdings = U.S. primary-income payments ÷ U.S.
liabilities (
IIPUSLIAA). - Differential = the first minus the second (the dotted line).
The income flows are reconstructed from the U.S. balance-of-payments panel: each is reported as a share of GDP, and is converted to a dollar level as (% of GDP ÷ 100) × GDP, then expressed in USD millions to match the BEA IIP stocks. Flows and stocks are aligned by calendar year over their common span, 1976–2023 (2024 income is not yet published).[1][2]
Reading the result
The differential stays positive across the whole sample: the U.S. consistently earns a higher implied yield abroad than it pays at home. That advantage is the privilege the thesis is about — and the composition shift is what could erode it. As foreign holdings of U.S. assets rotate toward corporate equities, foreigners increasingly receive stock-market returns rather than low Treasury yields, raising the yield they extract from the U.S. economy and narrowing the historic gap. The instrument-level split that pins this down — the Treasuries → equities rotation, from Fed Z.1 Rest-of-World data — shows foreign holdings moving from Treasury-dominated in the 1970s–80s to roughly two-thirds corporate equities by 2024, exactly the channel through which the differential narrows.
