The Bank of Korea just signaled rate hikes are back on the table

The Bank of Korea just signaled rate hikes are back on the table

We think the most important thing that happened this week is what a senior Bank of Korea (한국은행) official said on a stage in Samarkand. After two years of cutting and holding, the BoK is now openly saying hikes are back on the table, and that lands weeks before a brand-new governor chairs his first meeting. It changes how to read everything else in the brief: the KOSPI breaking 7,000, the won bouncing off Hormuz-era lows, and the loan math on every wolse (월세) deposit a foreign resident is sitting on.

Senior Deputy Governor Yoo Sang-dae (유상대) told reporters at the Asian Development Bank annual meeting in Samarkand, Uzbekistan, on May 4 that "it is time to consider halting rate cuts and moving toward a rate hike cycle," per the Korea Herald and Kyunghyang Shinmun. Yoo also said the possibility of a hike signal at the next meeting "is open." Korean primaries Hankook Ilbo and Newsis carried the same remarks. The board has not formally signaled a within-year hike before this.

Why this matters: the BoK base rate (기준금리) has stayed at 2.50% since May 2025, and a pivot to hikes changes the math on new and variable-rate mortgages, on the loans many tenants use to fund wolse deposits, and on the won/dollar rate that foreign residents watch when sending money home. Yoo's remarks are the strongest hike-direction signal from a senior official in two years.

The remarks are not policy yet. The next Monetary Policy Board meeting is May 28, the first chaired by new Governor Shin Hyun-song, who took office April 21. Markets have already begun pricing in two hikes this year, with some analysts seeing the benchmark reach 3% by year-end. The won closed at 1,462.8 per dollar on May 4, well off the 2026 lows reached during the late-March Hormuz disruption.

May 28 is when the signal becomes, or doesn't become, policy. The post-meeting statement and dot-plot tone will tell the story, not just the rate decision itself.

What Changed for Residents

What changed: The National Health Insurance Service (국민건강보험공단) processed the 2025 annual settlement on April paychecks, using NTS payroll data for the first time. About 10.35 million salaried workers (62% of eligible) owe an average of ₩220,000 more; 3.55 million whose income fell receive an average ₩115,000 refund. What this means for you: If you owe and want to spread the bill across up to 12 months instead of paying lump-sum, your employer must apply for installments by May 11, the April premium deadline. See our NHIS guide for foreign residents. NHIS notice.

What changed: The comprehensive income tax (종합소득세) filing window opened May 1; the deadline is June 1. It applies to anyone tax-resident in Korea who earned non-employment or multi-source income in 2025: freelancers, sole proprietors, landlords, and people with significant dividend or interest income. What this means for you: Tax residents present 183 days or more in 2025 owe worldwide-income reporting under Article 3 of the Income Tax Act; those resident under five years have a narrower foreign-source obligation. File via Hometax or your local tax office. See our income tax guide. NTS source.

Korea This Week

June 3 local elections, 30 days out: DPK leads Seoul, Incheon, Gwangju

With one month until Korea's 9th simultaneous local elections, the Democratic Party of Korea holds polling leads in Seoul, Incheon, and Gwangju, while the People Power Party contests Gyeonggi, Busan, and 14 National Assembly by-elections. An MBC-Korea Research poll (April 28-29, n=800, ±3.5pp) had DPK's Chong Won-o at 48% versus PPP Mayor Oh Se-hoon at 32% in Seoul. The semiconductor belt running through Pyeongtaek, Hwaseong, and Yongin has become a defining swing region as both parties court chip-industry voters, the Korea Herald reported.

Yoon and Kim Keon Hee receive harsher sentences on appeal

The Seoul High Court raised former President Yoon Suk Yeol's sentence to seven years on April 29 for obstructing his own arrest and bypassing the constitutionally required Cabinet meeting before declaring martial law in December 2024, per Kyunghyang Shinmun and Korea Herald. The day before, the same court raised Kim Keon Hee's sentence from one year and eight months to four years on Deutsche Motors stock manipulation and Unification Church bribery charges, per MBC News. Both sides filed Supreme Court appeals on May 4. On May 6, Shin Jong-oh, the High Court judge who chaired Kim's panel, was found dead near the courthouse; police are investigating as a suicide.

SK hynix tops ₩1,000 trillion; KOSPI breaks 7,000 on May 6

SK hynix shares rose 9.56% on May 4 to ₩1.409 million, pushing market cap above ₩1,000 trillion for the first time, Seoul Economic Daily reported, on Q1 revenue of ₩52.6 trillion (up 198% YoY) at a 72% operating margin from HBM demand. The KOSPI then broke 7,000 for the first time on May 6, finishing at 7,384.56 after an intraday high that briefly triggered a buy-side sidecar circuit breaker, per Hankyung. Samsung Electronics surged 14% the same day to cross $1 trillion in market cap. Together, Samsung and SK hynix represent more than 42% of the KOSPI.

April exports hit $85.9 billion, second-highest on record

April exports reached $85.89 billion, up 48% year-on-year, the second-highest monthly figure on record after March 2026's $86.6 billion, Korea Economic Daily reported. Semiconductor exports set a monthly record at $31.9 billion, up 173% YoY, on the same DDR4 and HBM demand driving SK hynix's quarter. The trade surplus of $23.77 billion was the largest April surplus ever; the consecutive trade-surplus streak now runs 15 months.

Samsung union coalition fractures ahead of May 21 strike

On May 4, the Samsung Electronics Co. Union (Donghaeng), with about 2,300 members from the Device Experience (DX) division, withdrew from the joint strike coalition, the Korea Herald reported. The trigger: the coalition's bonus demand of 15% of the Device Solutions division's operating profit, which could mean about ₩700 million per chip employee while DX workers, whose division posted a 36% profit decline, would receive nothing extra. The remaining coalition still plans an 18-day strike from May 21 to June 7, potentially affecting 40,000 workers. DS sites in Hwaseong and Pyeongtaek and DX sites in Suwon employ many foreign workers on E-7 visas.

One Number

₩1,462.8 to the dollar. The won closed Monday at this level after Yoo Sang-dae's hike-direction remarks, well off the late-March Hormuz-era lows but still weak by historical standards. For residents sending money home, BoK direction translates directly into the rate your remittance provider locks at send-time. Bank of Korea daily FX.
