Starbucks Korea Sales Slide After ‘Tank Day’ Campaign Triggers Backlash

Starbucks Korea is suffering a measurable sales decline following a promotional misstep that offended millions of South Koreans, Benzinga reported Tuesday, citing Yonhap News.

The controversy centers on a limited-edition tumbler campaign the brand called “Tank Day.” The promotion launched in close proximity to the anniversary of the May 18 Gwangju Uprising. That 1980 event saw military forces violently suppress pro-democracy protesters, leaving deep scars on the Korean national consciousness.

A Campaign That Misjudged the Moment

The timing drew immediate public fury. Critics accused Starbucks Korea’s operator, Shinsegae Group, of gross insensitivity toward a defining tragedy in modern Korean history. The backlash spread quickly across social media and translated into a measurable consumer retreat from the brand.

Shinsegae runs Starbucks Korea through its subsidiary SCK Company. E-Mart holds a 67.5% majority stake in SCK, while Singapore’s sovereign wealth fund GIC controls the remaining 32.5%. Shinsegae chairman Chung Yong-jin issued a public apology, acknowledging the campaign was inappropriate and accepting full corporate responsibility.

Background: Gwangju and the Weight of May 18

The Gwangju Uprising remains one of the most politically charged dates on the South Korean calendar. Hundreds of civilians were killed or wounded during the military crackdown under then-general Chun Doo-hwan. The anniversary is formally commemorated each year and carries enormous emotional weight across the political spectrum. Any commercial association with the date demands extreme care.

Starbucks Korea was previously the top food and beverage chain in South Korea by estimated customer count, according to data firm WISEAPP, covering the six months through February. That market position now faces sustained pressure.

Fallout, Firings, and a Wider Turnaround Story

Following the apology, Shinsegae dismissed the head of Starbucks Korea and opened an internal investigation to determine whether the misstep involved deliberate misconduct. The company admitted the episode exposed serious weaknesses in its risk management practices. Starbucks Global headquarters was kept informed throughout and separately issued its own apology.

The Korea episode adds pressure to a parent company already deep in restructuring. Earlier this month, Starbucks unveiled its “Back to Starbucks” plan, cutting roughly 300 U.S. corporate positions and closing regional offices in Atlanta, Chicago, and Dallas. The company expects around $400 million in total restructuring charges. Despite that, TD Cowen recently upgraded SBUX to Buy with a $120 price target. The stock is up roughly 23% year-to-date but slipped just under 1% on Friday to close at $103.11.
