Introduction

The overseas alternate (FX) swap market generates nearly $4 trillion in new contracts on any given day. To place that in perspective, think about international equities had a day by day buying and selling quantity of 12 billion.

How Do FX Swaps Work?

FX swaps are derivatives by way of which counterparties alternate two currencies. One celebration borrows a foreign money and concurrently lends one other foreign money. The quantity a celebration should later repay is mounted initially of the contract, and the counterparty compensation obligation serves because the transaction’s collateral. FX swaps thus are a straightforward manner for a celebration to shortly acquire greenback or FX funds.

FX Swaps: How They Work

On stability, the foreign money hole is totally hedged by the off-balance FX swap. One counterparty obtains extra lending in a overseas foreign money with out a rise on its stability sheet.

Although an FX swap in principle implies that the counterparties transact with one another, the truth is, banks are the primary intermediaries.

After they obtain a request from a shopper to hedge an publicity, banks supply the funds by way of matched-book or reserve draining intermediation. Within the former, the banks finance expanded FX lending by rising their repo borrowing and different liabilities. The primary downside of such an strategy is that it grows the financial institution’s stability sheet, which impacts its leverage ratio or liquidity protection ratio. Because the international monetary disaster (GFC), these Basel III ratios are binding and dear.

By means of reserve draining intermediation, banks can finance the greenback lending and thus cut back their extra reserve stability with the US Federal Reserve. This manner the dimensions of the stability sheet stays the identical, and the financial institution avoids any potential Basel III regulatory implications.

However there may be extra to the FX swap market: Banks additionally conduct FX arbitrage and market making, so the true FX swap market resembles the next chart. Banks deal with the three totally different positions — hedging, arbitrage, and market making — as fungible and simply handle the general foreign money publicity for all their actions.

A Rising Market

Why is the FX swap market increasing at such a speedy clip? Profitability is one key issue. Banks lend {dollars} by way of FX derivatives that pay a greenback foundation premium. That is what the banks make on prime of what they’d accrue just by lending on the cash market. The greenback foundation premium has been very profitable, particularly for banks with plentiful greenback funding. On the similar time, by turning to FX swaps, these banks are accommodating their purchasers’ hedging necessities with out affecting their Basel III ratios.

Expertise is one other often-overlooked contributor to the rising market. FX swaps are short-term devices, with greater than 90% maturing in underneath three months. Rolling the spot positions to the closest date can impose an administrative burden. Expertise can automate many of those duties and add different functionalities, corresponding to automated hedging and collateral administration. Innovation can be disrupting how FX swaps are intermediated. Telephone utilization is declining, whereas digital intermediation is increasing.

Such a big and profitable market must be fiercely aggressive. But US banks dominate, with the highest 25 accounting for greater than 80% of the positions. What explains this preeminence? As much as 90% of FX swaps contain the US greenback in a single leg. For instance, a Dutch pension fund conducting a euro-to-yen FX swap would first swap euros into {dollars} after which {dollars} into yen.

Opaque and Fragile

The primary danger posed by the FX swap market is the greenback squeeze. On this situation, these entities with out entry to Fed {dollars} purchase giant, short-term fee obligations. When the market capabilities easily, these FX swaps might be rolled over. However amid elevated market volatility, greenback funding could dry up, leaving non-US banks and entities to scramble to search out {dollars} to make good on their commitments. Finally, through the GFC and the COVID-19 pandemic, the Fed countered a greenback squeeze by offering swap strains to different central banks, funneling the wanted {dollars} on to them. Nevertheless, these strains got here with incomplete info given the market’s opacity.

The truth is, Dodd-Frank laws exempted FX forwards and swaps from mandated clearing, so the market has no central clearinghouse. Even with out a authorized obligation, about half the FX turnover was settled by the most important international FX settlement system, CLS, in 2022. By utilizing CLS, banks mitigate their settlement danger. This method has held up in periods of extreme monetary misery, and extra counterparties are selecting to settle with CLS. Nonetheless, the opposite half of the market stays over-the-counter (OTC) and unaccounted for. Which begs the query: what occurs through the subsequent interval of market turmoil? What number of {dollars} ought to the Fed present? To which international locations?

The FX swap market additionally suffers from a scarcity of value effectivity. Regardless of the large volumes traded, there may be clear proof of window dressing: As every month and quarter ends, intermediation spreads spike. In “FX Spot and Swap Market Liquidity Spillovers,” Ingomar Krohn and Vladyslav Sushko discover that costs usually are not solely distorted, however liquidity can be impaired. When globally systemically vital banks (G-SIBs) periodically pull out of the swap market to keep away from rising the so-called complexity element, it results in increased capital necessities.

However lowering regulatory publicity doesn’t cut back danger publicity. When banks intermediate in FX swaps, it impacts their intraday liquidity and intra-bank credit score and in the end modifications their asset composition modifications. That’s why the FX swap market wants each regulatory administration and efficient danger administration.

What’s Subsequent?

Expertise and elevated settlement by way of CLS could assist make the FX swap market extra clear and value environment friendly, however they’re no substitute for what’s actually wanted: extra intermediation competitors.

Reaching that may require reform, and that’s finest achieved by alternative and with foresight. The opposite choice is to attend for a greenback squeeze that the central banks can’t mitigate to pressure reform upon the market.
