Inside Korea’s Inbound Spending Boom: What Record Foreign Card Sales Mean for Retail and Payments

Foreign credit and debit card spending in Korea reached USD 4.86 billion between April and June, a 36.1 percent jump from the first quarter and past the previous peak of USD 3.79 billion set in the same quarter a year earlier. Headline numbers like that usually get filed under tourism. They belong just as much in a services file. Merchant-level data show foreign card sales running roughly 9.6 times their January 2023 level, and the shape of that growth — where it lands, who captures it, how it eventually settles — is a retail and payments question, not a visitor-arrivals question.

A record quarter, measured two different ways

The Bank of Korea's second-quarter tally is the broad aggregate: USD 4.86 billion spent on foreign-issued cards, up 36.1 percent from the first quarter and above the prior record of USD 3.79 billion in the second quarter of last year. The card count tells you where the growth came from. Some 25.02 million cards were used by foreign nationals in the quarter, 34.3 percent more than in the first, while average spending per card edged up just 1 percent to USD 194. Growth was overwhelmingly a matter of more cards presenting themselves at more terminals, not of each visitor spending appreciably more.

A separate merchant dataset adds texture. Korea Credit Data examined roughly 328,000 businesses nationwide that use its Cashnote management service and have a history of accepting overseas-issued cards. Indexed to January 2023 at 100, foreign card sales at those merchants stood 9.6 times higher as of June, having reached 989 in April. The two datasets are not interchangeable: one is a national balance-of-payments style aggregate in dollars, the other an index across a specific merchant panel. Read together they corroborate direction and pace; neither should be treated as the other's market share.

Where the money actually lands

Geography is where the boom stops looking national. Between July of last year and June of this year, Seoul absorbed 65 percent of foreign card sales in the merchant panel, with Gyeonggi Province at 11 percent, Busan at 8 percent and Jeju at 5 percent. The growth ranking inverts that order. Busan posted the fastest increase at 60 percent, followed by Jeju at 53.1 percent, Seoul at 36.4 percent and Incheon at 35.9 percent. Seoul remains the market; the second-tier coastal and island destinations are where the rate of change is steepest, which is usually where capacity and acceptance infrastructure lag hardest.

The calendar is equally lopsided. Foreign card sales rose consistently in April and May and again from September through November, tracking Korea's peak inbound seasons. For an operator, that is a staffing, inventory and cash-handling pattern before it is a marketing one, and it means annualised averages will understate what a shoulder-season week and a peak week look like on the same terminal.

Beauty, food and the winner-take-most merchant curve

Within services, beauty and medical categories drew a high share of revenue from foreign cards. The colour contact lens brand Hapa Kristin recorded 34 percent of its sales through foreign-issued cards, and the sandwich chain Eggdrop, the Korean cuisine brand Solsot and the hair salon franchise Juno Hair all reported relatively high proportions of foreign card revenue against total sales. The pattern is consistent with a visitor basket weighted toward appearance-related services and quick, recognisable food formats rather than big-ticket durables.

Concentration at the merchant level is the sharpest finding in the dataset. Among surveyed businesses, the top 1 percent by foreign card sales accounted for 66.9 percent of the category total over the past year, and the top 10 percent accounted for 90 percent. A rising national index therefore describes a curve, not a tide. Most merchants in the panel share the remaining tenth, and for them the practical question is whether foreign card acceptance is a meaningful revenue line at all or an occasional transaction type worth handling cleanly but not building a strategy around.

The other side of the ledger

One figure keeps the boom in proportion. Residents of Korea spent USD 5.85 billion on cards abroad in the same second quarter, down 4.2 percent. Outbound card spending still exceeded inbound spending in the period even as it declined, so the record quarter narrows a gap rather than reversing it. Anyone building a business case on inbound consumption should hold both numbers in view.

Currency plumbing: the won internationalisation roadmap

Payments change is not only commercial. A government roadmap released on 19 July sets out that people of any nationality can freely use the won overseas, including opening won-denominated accounts at banks abroad. Following the launch of 24-hour trading on the foreign exchange market, the roadmap permits unrestricted won transactions between foreign users through offshore settlement institutions. To finalise those transactions, the Bank of Korea will launch an offshore won settlement network operating around the clock in January.

Adjacent measures point the same way. The reporting threshold for capital transactions such as won-denominated loans to foreign borrowers will be more than doubled, and 22 of the 25 capital market tasks identified by index provider MSCI have been completed. None of this changes what a visitor taps at a counter tomorrow. It changes the currency, timing and counterparty options available to the banks, acquirers and cross-border processors sitting behind that counter, and a round-the-clock settlement rail removes a constraint that has long shaped how offshore won exposure is priced.

What operators can reasonably plan around

Three judgments seem defensible from this evidence, and they are editorial reading rather than official guidance. First, acceptance quality is a distribution problem: in fast-growing but lower-share markets such as Busan and Jeju, the constraint is more likely terminal reliability and staff familiarity than demand. Second, the twice-yearly spring and autumn peaks argue for treating foreign card volume as a seasonal capacity plan with defined shoulder periods. Third, January's settlement network launch gives payment partners a concrete date to ask their providers about, well before it becomes a differentiator.

The limits are worth stating plainly. The merchant panel covers one service provider's customer base, not the whole retail economy, and it measures credit and debit card activity only — the split across mobile wallets and QR-based payment methods is not captured here, which matters given how many inbound visitors default to them. And with roughly two thirds of panel volume sitting in the top 1 percent of merchants, a smaller operator's honest planning question is not how to capture a national boom, but whether their own terminal data shows any of it arriving.
