Big-box hypermarket sales rebound after five-month slump; convenience store growth slows to 0.8%
Online retail share nears 60% as physical stores battle for foot traffic through aggressive low-price strategies and promotional discounts
South Korea’s hypermarkets and convenience store chains are doubling down on price wars to claw back market share. With the online sector now capturing nearly 60% of retail consumption, offline retailers are increasingly relying on low-price private label (PB) goods and extensive promotional incentives to entice consumers. While hypermarket sales rebounded in August after five months of decline, the sluggish performance of convenience stores highlights a growing divergence in the retail landscape.
According to the Ministry of Trade, Industry and Energy’s latest retail trends report, hypermarket sales in August rose by 4.5% compared to the same period last year. In contrast, convenience store sales growth stalled at just 0.8%, while online retailers saw an increase of 9.3%.
Offline retailers are focusing on lowering prices for daily necessities. Hypermarkets are expanding their "ultra-low-price" offerings through private label brands, while convenience stores are aggressively rolling out card and membership discounts on fresh produce and household staples.
Lotte Mart reported that sales of PB products priced under 5,000 won surged 37% year-on-year between January and September. The retailer has scheduled a promotion from the 15th to the 28th, offering discounts of up to 40% on select PB goods. Meanwhile, CU is offering card-linked discounts on essential groceries through the end of the month, alongside various membership-based promotions.
Hypermarket Rebound vs. Declining Convenience Store Transactions
The August increase in hypermarket sales marks a reversal of a five-month downward trend. Between March and July of this year, hypermarket sales had recorded consistent declines of 15.2%, 6.6%, 5.1%, 10.5%, and 11.2%, respectively.
The August uptick was largely driven by the Chuseok holiday gift-set season. As the holiday fell earlier this year compared to the previous year, festive-related spending was concentrated in August. Food sales at hypermarkets climbed 5.4%, while the electronics and toy segments saw a 17.8% jump.
Growth in the convenience store sector, however, is decelerating rapidly. Sales growth, which stood at 5.1% in June, dropped to 1.1% in July and 0.8% in August. While the average transaction value has risen, the frequency of store visits has declined, curbing overall revenue gains.
In July, the number of transactions at convenience stores fell by 0.5% year-on-year, even as the average purchase value rose by 1.6%. This trend of fewer but larger purchases continued into August, suggesting that while consumers are spending more per visit, they are visiting stores less frequently.
During the same period, department store sales grew by 11.9%, recording the highest growth rate among all offline retail sectors. While total offline retail sales rose by 5.4%, performance gaps between formats remain stark. Given that hypermarket growth was bolstered by holiday seasonality and convenience stores continue to see falling transaction volumes, it is premature to conclude that offline consumption has made a full recovery.
Online Market Share Hits 60%: The Pressure of Offline Price Wars
The desperate discount race among offline retailers is inextricably linked to the broader shift toward e-commerce. As price comparison and online shopping become the retail standard, hypermarkets and convenience stores find themselves compelled to sharpen their price competitiveness.
Industry data shows that the online share of total retail sales has climbed to 59.7%, up 6.7 percentage points from 53.0% in 2022. During the same period, the share of hypermarkets shrank from 13.0% to 9.0%. (Note: These figures are based on a survey of 26 major retailers and may differ from total national market share.)
Hypermarkets are leaning into fresh produce and private labels, while convenience stores are pivoting to small-portion and convenience-oriented meals to maintain relevance. By bundling card discounts and membership loyalty programs, they hope to encourage repeat customer visits.
However, the longer this discount war persists, the greater the threat to profitability. Even if sales volume increases, deep discounting inevitably erodes margins. Offline retailers face the difficult dual challenge of securing customer traffic through low prices while simultaneously protecting their bottom line.
