The dominant framing of compressed real rates — that they are a residue of pandemic-era policy soon to normalise — mistakes a structural feature for a cyclical bug. Real short-term rates across the developed world sit at historic lows, with several major economies in negative territory. The mechanism running underneath is not central-bank preference but debt arithmetic: the stock of sovereign and private liabilities accumulated over forty years cannot be serviced at positive real rates without forcing defaults or fiscal retrenchment neither political system will tolerate. Savers pay the difference.
The case, laid out most forcefully by Santiago Capital, runs as follows. US federal debt and the Federal Reserve's balance sheet have expanded for four decades without meaningful retreat. Structural deglobalisation — the unwinding of the low-cost, low-inflation supply architecture of 1990-2015 — now requires fiscal expansion to underwrite reshoring, defence, and energy transition. That fiscal load is only serviceable if real rates (nominal policy rates minus inflation) stay compressed. Accommodation, in this reading, is not a choice the Fed is making cycle by cycle. It is the non-optional cost of carrying the existing stock of system debt.
The saver's tax is not a forecast. It is the present tense.
The implications for portfolio construction are more disruptive than the macro debate has priced. Cash has lost purchasing power after inflation for most of the last fifteen years — a fact worth sitting with, because it inverts the mental model most allocators still use for the risk-free leg. The 60/40 portfolio's central assumption — that bonds rally when equities fall — has been breaking down since 2020, as inflation-driven drawdowns correlate rather than offset. If real rates are structurally pinned below zero to service debt, the duration hedge in a balanced portfolio is not merely weakened; its economic rationale is inverted. Bonds become a claim on a currency being deliberately debased at the margin.
The transitory tell
The dossier is one-sided: every forecast in the cluster comes from a single research shop, and each sits on the same side of the argument at medium conviction. Santiago Capital assigns YES to real short-term rates remaining compressed or negative over the next two years, and to the US maintaining that configuration without a currency crisis over the same window. Readers should treat this as a coherent thesis rather than a consensus — the counter-case, that a genuine productivity shock or a fiscal consolidation could restore positive real rates, is not represented here and deserves its own hearing. What the thesis does well is operationalise: each claim resolves cleanly on observable two-year data. The dollar's structural reserve position is the load-bearing assumption. If it holds, the saver's tax compounds quietly. If it breaks, the resolution is not a soft landing but a currency event — and that is the tail the framework itself concedes.
