Fifteen per cent of $530bn in foreign holdings [4][8] is $79.5bn of hedge notional [11], and the increase from the old 10 per cent cap accounts for $26.5bn of that on its own [12], none of it being executed while the trigger sits where it does [2][3]. Set that against the $65bn of extended Bank of Korea swap lines running to the end of 2026 [9], which is about 82 per cent of a fully drawn 15 per cent program [13]: the facility is roughly scaled to a hedge book that is currently switched off.
The forwards and swaps arranged through the Bank of Korea put dollars into the onshore market, which leans against the won when it is weak [6]; pause them and that supply is gone while the overseas investment flow continues, so net dollar demand from the fund rises [7]. With roughly 53 per cent of the $1trn portfolio held abroad [14], the allocation abroad is the flow and the hedge was the offset, and that offset has now been withdrawn.
Anyone trading the currency can now read the reaction function directly off the triggers. The down-trigger fired after roughly 7 per cent of won appreciation from above 1,450 into the mid-1,300s [16], and market sources cited by cryptobriefing.com put the resumption level above 1,550 [10], which leaves a band about 200 won wide, near 15 per cent of won weakness, in which the fund is not scheduled to sell a dollar [15]. That is a disclosed option, written by the third-largest public pension fund in the world [1], and it is free to whoever wants to position into it.
Calling this a supply shock in USD/KRW forwards is more than the evidence carries. The material gives no executed hedge notional, no effective date for the stop, and no tenor for the forwards already on the book, so whether the pause removes $5bn of rolling supply or $50bn is not established [17]. Two other readings survive the same evidence. The hedge may have been small in practice, in which case forward points barely notice a program that only recently rose from a 10 per cent cap [4]; or the 1,550 level, which rests on unnamed market sources rather than the fund [10], turns out to be soft, and anyone who sold won toward it discovers the seller arrives early, or late.
The view this desk will take, and it is the narrower one: the tradable fact is the threshold, not the size. Trigger-based management of the sort cryptobriefing.com describes as a broader institutional trend [18] converts a hedging policy into a published price at which a very large counterparty changes side, and published prices get tested. In the meantime the fund is paying no forward points on up to $79.5bn [11], drawing on none of the swap capacity that expires at the end of next year [9], and supplying none of the onshore dollars that used to cushion won weakness [6]. That last job now sits with the central bank alone, until the rate travels the 200 won it would take to hand part of it back [15].
