Few workers can say that their bonuses have been so large that the country’s central bank takes notice.

But in South Korea, that phenomenon is playing out as workers from tech industries receive bonuses worth millions of won, prompting the Bank of Korea to warn of the upward pressure to inflation.

In a June 17 report, the central bank wrote that inflation this year has been largely powered by energy price increases due to the Iran war. But, it adds, even if that conflict subsides, inflationary pressures may gradually increase as income conditions improve and wage growth becomes more widespread.

More notably, the BOK said that the payment of large performance bonuses recently seen at some major companies in the IT sector could spread into broader wage increases, translating to upward pressure on inflation.

This comes as South Korea is already experiencing above-target inflation, with the BOK projecting that full year inflation will come in at 2.7%, above its 2% target.

The BOK’s observations come after reports that huge bonuses were paid out to employees at tech companies, especially those at chip heavyweights SK Hynix and Samsung Electronics.

While the exact amount was not disclosed by the companies, SK Hynix agreed last September to a wage deal that will set aside 10% of operating profits as bonuses for its workers.

Samsung workers had reportedly agreed that 10.5% of its semiconductor operating profit will go towards special bonuses for chip ​workers, after threatening an 18-day strike in May.

According to an unidentified union source cited by Reuters, a memory chip worker with a base ​salary of 80 million won ($52,400) is expected to receive a total bonus of around 626 million won ($410,000) this year.

SK Hynix employees are expected to receive bonuses of more than 700 million won ($454,851) if the firm achieves an annual profit of 250 trillion won this year, according to Reuters calculations.

The BOK said that normally, bonuses would not contribute much to demand pressure, as they are not permanent increases to income.

But when “special bonuses expand unusually and substantially,” wage growth could could spread to other sectors, significantly increasing both supply- and demand-side inflationary pressures, the central bank said.

“In particular, because recent IT-sector performance bonuses have been paid on a highly exceptional scale, the possibility that their actual impact could be larger than expected cannot be ruled out,” it added.

Starbucks will award baristas and shift supervisors quarterly bonuses of $300 if their stores hit certain targets to aid the coffee chain’s turnaround efforts, the company said Thursday.

The program will begin in July, with the first payout coming in the fall to store employees who meet or exceed specific sales, operational and customer service metrics, Starbucks Chief Operating Officer Mike Grams and Chief Partner Officer Sara Kelly wrote in a memo to employees on Thursday.

However, baristas at locations represented by Starbucks Workers United likely will not see the quarterly bonuses until Starbucks and the union reach a collective bargaining agreement.

“This new program, at the approximately 5% of U.S. locations where partners have a union, will be subject to collective bargaining as required by federal law,” Grams and Kelly said in the letter.

Negotiations between Starbucks and union have been at a standstill for more than a year. In March, the company said that it had proposed to resume in-person bargaining with Workers United. Talks between the two parties are expected to resume this month.

Under CEO Brian Niccol, Starbucks has been undergoing a turnaround focused on getting “back to Starbucks.” Much of the strategy has centered on improving the customer experience, from making its cafes cozier to requiring baristas to write messages on cups.

But the turnaround plan also hinges on its baristas and their willingness to carry out Niccol’s vision. Starbucks has tried to improve the barista experience, with improved staffing and plans to add assistant managers to most North American locations this year.

More changes are ahead for baristas. The company also announced on Thursday that it will give customers more methods to tip their baristas. Anyone who orders and pays through the mobile app will be able to tip, as well as customers who scan the app at the register to pay.

Combined with the new bonuses, baristas could see their pay rise as much as 8% as a result, according to the company.

Additionally, all Starbucks U.S. employees will be paid on a weekly basis, starting in August. Currently, most baristas receive their paychecks every other week, depending on local labor laws.

So far, the “Back to Starbucks” strategy is starting to pay off for for the company. Last quarter, the chain reported traffic growth for the first time in two years.
