South Korean stocks are extending a spell of extreme volatility, with circuit breakers and sidecars triggered in turns. Investor sentiment is recovering as geopolitical tensions ease, but sources of market anxiety remain. The won rose as far as 1,555.2 per dollar during the session, prompting foreign exchange authorities to issue a verbal warning, saying speculative currency trading is amplifying volatility.

Market attention this week is on the U.S. Federal Open Market Committee, and some expect volatility in South Korean stocks could widen again depending on the rate path and currency moves.

Against that backdrop, investment fervour over the SpaceX listing is running high. SpaceX drew demand from U.S. retail investors, with its offering succeeding despite controversy over an overvaluation.

With its corporate value assessed at well above $1 trillion, expectations for short-term gains and long-term growth worked at the same time. After the listing, SpaceX's market capitalisation was assessed at 210 trillion won, drawing attention to the expansion of Elon Musk's asset value.

Still, expectations among South Korean investors for direct investment ran into some setbacks.

Mirae Asset Securities' allocation of SpaceX shares was fully cut, and Korea Investment Trust Management did not receive an allocation either.

Korea Investment Trust Management instead added SpaceX to its ACE U.S. Space Tech Active ETF through on-exchange purchases on the first day of trading.

Even before the listing, the firm's space-themed ETF saw net buying of 60 billion won, showing demand for indirect investment linked to SpaceX.

Growth in household lending has resurfaced as a key variable for the financial sector. With household loans jumping 9.3 trillion won in a month, financial authorities activated an emergency management system and signalled tighter loan controls.

Banks also moved to respond pre-emptively. KB Kookmin Bank decided to cap general unsecured credit loans at 100 million won and overdraft limits at 50 million won. Shinhan Bank began moderating the pace by limiting non-face-to-face credit loan applications when daily intake exceeds a certain level.

Products tied to vulnerable groups, such as loans for low-income financing and policy loans, will apply separate standards, leaving room to protect end users.

On the monetary policy front, Bank of Korea Governor Shin Hyun-song (신현송) said there is a need to raise rates without delay to stabilise prices, increasing the possibility that borrowers' interest burdens could rise.

As global supply chains are reshaped and competition over technological hegemony intensifies, financial policy has entered a phase that must consider household debt management and productive allocation of finance, beyond simply expanding funding supply.

AI is spreading across finance in both service upgrades and risk management.

Ant Group is testing AI agents in Alipay, expanding functions from ordering coffee to buying funds across everyday payments and wealth management.

Visa and OpenAI have also moved to build an agent commerce infrastructure based on a global payments network to support transactions led by AI agents.

In South Korea's financial sector as well, the use of AI is moving beyond support for consultations and search into actual financial transactions and customer touchpoints.

KakaoBank said users of its conversational AI service topped 5 million a year after launch, widening usage to financial calculations, transfers and searches for investment information. KakaoBank is also upgrading an AI model that analyses users' transaction context to strengthen its ability to detect financial fraud.

As traffic grows from AI agents accessing financial websites, security challenges are also increasing as firms must distinguish normal automation from malicious activity.

Financial authorities and the industry are moving in tandem on easing network separation rules, AI security testing and overhauling voice phishing response systems, in a push to strengthen consumer protection measures suited to the spread of AX.

Other major moves in finance and fintech were also compiled.

KB Kookmin Bank is running an event to support the purchase of terminals for small business merchants. KB Securities' digital wealth management assets topped 15 trillion won, up by about 5 trillion won in 6 months, as demand for tax-saving and retirement-prep products such as ISAs and pensions drove growth.

Mirae Asset Securities signed a contract with Singapore brokerage UOB Kay Hian to provide an integrated account service for foreigners and began the service. The aim is to improve foreign investors' access to South Korea's stock market and broaden the base for attracting global investors.

Shinhan Financial Group decided to write off 500 billion won in delinquent debt and supply inclusive finance worth a total of 4.5 trillion won. Shinhan Bank is also expanding support for low-income finance by widening preferential interest rates for Saehopeum Holssi loans and extending instalment repayment periods.

Hana Financial Group will create a 50 billion won new growth fund for companies located in industrial complexes, and Woori Bank will analyse customers' debt status and repayment burdens through an AI-based "inclusive debt diagnosis" service.

Woori Investment & Securities said that a text message related to a reflection period system was sent in error to some customers due to an error during testing.

KakaoBank supplied an additional 1.2 trillion won in loans to mid- to low-credit borrowers using non-financial data, and K Bank strengthened its deposit competitiveness by offering a preferential rate on its Plus Box product.

Simple payment and remittance services expanded into everyday finance areas such as transport, tuition payments and overseas QR payments.

Toss FacePay subscribers topped 6 million, and Banksalad highlighted the average interest-saving effect for users of its refinancing loan service. Payment errors and duplicate withdrawals continued, bringing the stability of fintech services into focus as a challenge.
