Amid imbalances in provide and demand within the overseas change market, the Financial institution of Korea has declared this to be an occasion of “poverty amid loads”: Whereas the foreign exchange swap market is brimming with {dollars}, the spot market doesn’t have sufficient.
Yoon Kyoung-soo, the director basic of worldwide affairs for the central financial institution, posted a chunk on the BOK weblog on Monday titled, “Why is the change price rising when there are many {dollars} within the foreign exchange market?”
Yoon’s weblog publish supplied his evaluation and clarification for what he referred to as a “seemingly paradoxical” scenario Korea finds itself in.
The overseas foreign money and capital markets contain monetary establishments and banks lending cash to actors; in change, they obtain curiosity on the repayments. Usually, an actor places up Korean gained as collateral to borrow {dollars}; after a sure interval has handed, the borrower is obliged to pay again the greenback principal in change for its pertinent worth in gained. That’s an FX swap, the first sort of transaction within the foreign exchange market.
At present, the rate of interest for borrowing gained in Korea is 2.4% (three-month foundation). Within the US, individuals are charged an rate of interest of three.6% when borrowing {dollars}.
That distinction in rate of interest implies that when placing up gained as collateral and borrowing {dollars}, the lenders have to pay no less than 1.2% in curiosity. As a result of the US greenback is the worldwide reserve foreign money, folks borrowing {dollars} pay an extra premium on that base rate of interest, because the greenback is in increased demand in comparison with different currencies.
The extent of that greenback premium is set by the legal guidelines of provide and demand. If there’s a excessive provide of {dollars}, demand shrinks; if demand for greenback loans is excessive, then the worth of every greenback will increase.
On Dec. 15, the greenback premium decreased by as many as 0.004 proportion factors (three-month foundation). Between late June 2025 and the tip of final yr, it fell 0.022 proportion factors. Not too long ago, the greenback premium has been nearing 0%. As a result of there’s little revenue to be made by loaning {dollars}, it’s develop into simpler for debtors to acquire {dollars}.
In accordance with Yoon, the rise within the quantity of {dollars} within the foreign exchange market is because of the upkeep of constructive nationwide steadiness sheet; the rise within the quantity of {dollars} held by Korean companies, who rely totally on exports, with out exchanging them for gained; and the rise within the quantity of state bonds held by overseas buyers (as a hedge in opposition to the foreign exchange market).
Conversely, the rarity of {dollars} within the spot market — the place precise {dollars} are immediately traded for precise gained — has led to the Korean gained plummeting in worth.
It’s like a automotive market the place the variety of leases is surging whereas no person really desires to promote or purchase a automotive. The price of renting goes down, whereas the precise worth of vehicles doesn’t change, and even goes up.
Throughout a press convention final week, BOK Governor Rhee Chang-yong addressed provide and demand within the foreign exchange market.
“The issue lies in the truth that individuals are anticipating the change price to rise, subsequently solely lending {dollars} as an alternative of promoting on the spot market,” Rhee stated.
The BOK has concluded that the general rise within the worth of the greenback in comparison with the gained in recent times is because of disparities in base rates of interest and financial development; it’s additionally because of the comparatively decrease income generated by home monetary property. Nonetheless, the BOK insists that won-dollar change price actions seen within the fourth quarter of 2025 have been primarily brought on by volatility in provide and demand within the foreign exchange market.
The issue is the rising damaging public sentiment concerning the rising change price. Yoon of the BOK wrote, “Proper now, the greenback might be borrowed at traditionally low charges, so we’re removed from a foreign exchange disaster.”
“If the view {that a} rising change price is indicative of weakening financial fundamentals spreads, it may result in capital flight overseas, which might exacerbate the change price,” he stated, calling this prospect a “self-fulfilling vicious cycle.”
