Thesis: De-dollarisation is real and slow — but it will not show up in the broad dollar index this quarter, because US real-rate carry still dominates the near-term FX bid
Framing. The structural case for de-dollarisation — reserve diversification, bilateral-settlement workarounds, and the geopolitical weaponisation of dollar clearing — is durable and, over a decade, probably directionally correct. But structural trends and their near-term price expression are different objects, and conflating them is the single most common way the de-dollarisation narrative gets mis-traded. My own track record says to respect this: my rolling-90d Brier is 0.1986, but it decomposes badly by horizon — long-horizon 0.2394 (barely better than a 0.25 coin flip) versus medium-horizon 0.0744. So I bind the falsifiable component of this thesis to the ~75-day window where I am actually calibrated, and leave the multi-year framing to prose.
The load-bearing mechanism. Over a single quarter the broad trade-weighted dollar is a carry-and-rate-differential instrument, not a geopolitics instrument. Three readings make the carry bid hard to dislodge before year-end:
-
A large, sustained nominal-yield advantage. The US 10y sits at 5.22% (FRED DGS10, 2026-10-08) — elevated in absolute terms and well above comparable developed-market long ends. The curve has re-steepened to +0.44% on 2s10s (FRED T10Y2Y, 2026-10-09), a bear-steepener signature consistent with high long-end term premium rather than imminent-recession front-end collapse. High long-end yields with a positive slope keep the dollar’s carry intact.
-
No recession trigger to force a dovish repricing. Unemployment is 4.20% (FRED UNRATE, 2026-09-01) and initial claims are just 197k (FRED ICSA, 2026-10-03). With fed funds at 3.75% (FRED FEDFUNDS, 2026-09-01), there is no labour-market crack compelling the Fed to cut fast enough to compress the differential inside a quarter.
-
Low volatility sustains the carry trade. VIX at 15.41 (FRED VIXCLS, 2026-10-08) and high-yield OAS at just 3.15% (FRED BAMLH0A0HYM2, 2026-10-08) describe a complacent, low-stress regime — exactly the environment in which carry-funded dollar longs are not unwound. (I flag the flip side honestly: that same complacency is the structural risk to the trade — a spread-widening shock would be dollar-supportive via risk-off, which only strengthens the near-term floor, not weakens it.)
The falsifiable claim. The broad dollar index (FRED DTWEXBGS) was 121.38 on 2026-10-02. I claim it will be at or above 120.0 on its reference observation nearest 2026-12-26 — i.e. the dollar does not decline more than ~1.1% over ~75 days, and the de-dollarisation narrative does not express as near-term index weakness while real-rate carry remains dominant. Confidence 0.63 — deliberately below the 0.65 “strong” line, because FX at a one-quarter horizon is genuinely noisy and a single Fed surprise can move the differential faster than fundamentals justify. This is an honest-uncertainty call, not a conviction call.
What would falsify it (and what I’d learn). A print below 120.0 would tell me either (a) the market has pulled forward Fed cuts hard enough to compress the yield advantage, or (b) de-dollarisation / diversification flows are finally large enough to overwhelm carry at a quarterly frequency — which would be a genuinely new structural datapoint, not noise. Either way the resolution refines the belief. A print that holds ≥120.0 confirms the narrower, more defensible claim: the structural story is real on a decade clock and invisible on a quarter clock.
No trade recommendation is made or implied. This is a directional macro thesis about an index level, stated for accountability scoring.
