For the second consecutive time, South Korea's central bank raised interest rates. Against the backdrop of inflationary pressures, a warming Seoul real estate market, and improving economic prospects, the benchmark interest rate was increased by 25 basis points to 3%. This indicates that South Korea's monetary policy continues to tighten, also subjecting the local stock, real estate, and crypto asset markets to higher funding costs.
Two consecutive interest rate hikes
After the South Korean Central Bank announced a rate hike on Thursday, the benchmark interest rate rose from 2.5% before July to 3%. Among the 7 members of the Monetary Policy Committee, 6 supported this rate hike, while Hwang Kun-ik advocated for keeping the interest rate unchanged.
This is the second consecutive time that the South Korean Central Bank has taken action to raise interest rates after it had been more accommodative in the previous period. The interest rate hike in July was the first time the bank has raised rates since January 2023, and the latest decision has pushed borrowing costs back to the level before the rate cut in February 2025.
Core inflation and housing prices are the main causes
Although South Korea's overall consumer inflation rate fell to 2.8% in July, the core inflation rate, which is of more concern to policymakers, rose to 2.6%, reaching a new high since December 2023. This gives the Bank of Korea reason to continue to maintain a tight monetary policy stance.
The property market also constitutes a source of pressure. In Seoul, the transaction prices of apartments rose by 2.5% month-on-month in June, representing the largest monthly increase since June 2021. The accelerating rise in housing prices has also increased concerns regarding household leverage and financial stability.
The Bank of Korea also raised its economic growth forecasts, expecting the South Korean economy to grow by 3.3% in 2026 and 2.9% in 2027, which is higher than the previous projections of 2.6% and 2.1% in May. Strong semiconductor exports, as well as investment driven by global AI demand, are seen as the main supporting factors.
Pressure is exerted on preferences for encrypted transactions.
The impact of higher interest rates is not limited to the bond and real estate markets. South Korea has always been one of the most active markets for retail trading in Asia, with a high level of local capital participation in high-volatility assets.
Recently, the activity in South Korean cryptocurrency trading has shown a clear rebound. Upbit At one point, the hourly trading volume reached approximately 1.15 trillion Korean won, which is about 830 million US dollars. XRP and TRUMP have attracted new retail investors. By the next day, the daily trading volume had risen to about 3.81 billion US dollars.
In this context, the South Korean Central Bank's entry into a tightening cycle has a more practical impact on the digital asset market. Rising deposit rates and borrowing costs typically increase the returns on holding cash, while also raising the costs of leveraged trading, thereby diminishing the attractiveness of some speculative positions.
South Korean investors have a long-term preference for trading a single altcoin in a concentrated manner. Taking Upbit as an example, the trading volume of XRP recently exceeded that of Bitcoin by more than twice, indicating that the local liquidity switches between different tokens quite quickly.
At the same time, South Korea is also advancing regulatory adjustments for digital assets, including preparing to implement a crypto tax starting from 2027, and promoting the development of Korean won stablecoin projects such as KRW1. For the market, the next focus will be whether a interest rate level of 3% is sufficient to curb inflation and the housing market. If price and housing price pressures continue, the South Korean central bank may still further tighten its policies.
