The Seoul AI Innovation Tour 2024 comes to an end, sharing insights on digital finance

SBI Zodia Custody is discontinuing operations two years after its launch, Bloomberg reported. The joint venture was formed by Tokyo-based SBI Holdings and Zodia Custody, an institutional digital-asset platform backed by Standard Chartered, with ownership split 51% and 49% respectively.Photo by Haotian Zheng on UnsplashStrategic realignment behind exitAccording to people at the companies involved, the decision reflected shifting priorities at both partners. Zodia Custody chief executive Julian Sawyer described the move as a mutual alignment of strategy and said the company had prepared materials to seek local registration with Japan’s Financial Services Agency but had not filed an application before opting to exit. An SBI Holdings spokesperson said the dissolution did not signal a withdrawal from crypto custody or the company’s broader Asia strategy, describing the step instead as an effort to generate greater collective impact across SBI’s digital ecosystem. Security breaches shape regulatory climateThe retreat comes as overseas crypto businesses continue to face a cautious regulatory environment in Japan, a market shaped by several high-profile security breaches. Industry analyses have repeatedly noted that three of the largest crypto hacks targeted Japanese exchanges: Mt. Gox in 2014, Coincheck in 2018, and DMM Bitcoin in 2024. Mt. Gox lost about 850,000 BTC, now worth roughly $98 billion, and began making creditor repayments in July 2024 after years of legal proceedings. The repayment deadline was later extended to Oct. 31, 2025, and initial distributions totaled about 59,000 BTC, or just over 41% of the roughly 141,686 BTC earmarked for repayment, to an estimated 127,000 creditors. Coincheck’s 2018 breach involved what was then about $534 million in NEM tokens. Despite that episode, the company secured approval from the U.S. Securities and Exchange Commission (SEC) in November 2024 for a Nasdaq debut through a merger with Thunder Bridge. The transaction generated roughly $31.6 million in gross proceeds for the combined company. Moving forward, Coincheck is entering Europe through the acquisition of Aplo, a French-licensed digital asset brokerage. The most recent breach involved DMM Bitcoin, which had suspended operations after a May 2024 theft of more than 4,502.9 BTC. Its accounts and assets were transferred in March 2025 to SBI VC Trade, a cryptocurrency exchange owned by SBI Holdings, which said it would support 14 tokens previously listed on DMM that were not available on its own platform. Policy uncertainty as leadership shiftsAt the policy level, uncertainty is growing over Japan’s stance on crypto and blockchain following Prime Minister Shigeru Ishiba’s Sept. 7 announcement that he will step down. Ishiba, who took office in October 2024, has advocated for digital assets, with his latest remarks delivered at the WebX2025 event. There, he pledged greater state support for Web3 initiatives, describing the sector as a driver of innovation that could help address demographic decline and support broader economic change. Last month, Finance Minister Katsunobu Katō, seen as a potential contender to succeed Ishiba, said cryptocurrency could play a role in a diversified investment portfolio, noting its growing user base in Japan. While recent surveys show Sanae Takaichi and Shinjiro Koizumi as the leading preferences for the next Liberal Democratic Party leader, Katō has emphasized the need to foster a stable trading environment for digital asset stakeholders, balancing investor protection with industry innovation. Within this policy climate, SBI Zodia Custody’s shutdown underscores the operational and licensing challenges facing foreign-linked crypto ventures in Japan. 

JPEX Exchange Scandal Sees Crypto Regulation Under Scrutiny in Hong KongWhile Hong Kong has been developing steadily as a crypto sector hub, the focus in the Chinese autonomous territory has turned towards regulation after a recent scandal involving an unlicensed cryptocurrency exchange.Photo by Ihor Saveliev on UnsplashOngoing investigationYesterday we reported on some arrests relative to problems experienced at crypto exchange JPEX. The fallout continues on Tuesday, with the Hong Kong police now understood to have arrested eight individuals, including social media influencers who promoted the exchange and JPEX employees, on allegations of fraud. This illicit activity in and around the JPEX exchange has affected over 1,600 investors, implicating more than $150 million in assets.JPEX, in response to mounting pressure, announced the suspension of trading on its platform. In a statement, the exchange mentioned ongoing negotiations with third-party market makers to address liquidity shortages. However, JPEX also accused an unidentified third-party market maker of maliciously freezing funds, further complicating the situation.Politicians and regulators speak outResponding to the incident via a press conference on Tuesday, Hong Kong’s Chief Executive, John Lee, emphasized the significance of investing in virtual assets through licensed platforms. Lee stated:“This incident highlights the importance that when investors want to invest in virtual assets, then they must invest on platforms that are licensed.” He also pledged that the Securities and Futures Commission (SFC) would closely monitor the situation to ensure investor protection.Elizabeth Wong, the Head of the SFC’s fintech unit, revealed that an investigation was underway to determine whether JPEX had violated anti-money laundering laws. The SFC had already declared JPEX unlicensed, prompting numerous complaints from investors who were unable to withdraw their virtual assets or experienced unexplained reductions in their balances.Assets frozenHong Kong authorities have taken decisive action against those involved in the scandal. They have frozen bank accounts valued at 15 million Hong Kong dollars ($1 million) and seized three properties valued at 44 million Hong Kong dollars. The police have reported receiving 1,641 complaints related to JPEX, involving a staggering $1.2 billion Hong Kong dollars. By last Wednesday, the SFC had received in excess of 1,000 complaints and at that point, they notified the general public.The JPEX scandal has drawn attention to the need for stronger cryptocurrency regulations in Hong Kong, a region that has become attractive to cryptocurrency firms since mainland China banned cryptocurrency transactions in 2021. In mainland China, trading cryptocurrencies on foreign exchanges from within the country remains illegal.Hong Kong’s response to cryptocurrency regulation has evolved. Beginning on June 1, the SFC started accepting applications from cryptocurrency exchanges, allowing licensed operators to serve retail investors, provided they understand the associated risks. Previously, only professional investors had access to such exchanges. Currently, only two exchanges in Hong Kong, OSL Exchange and Hashkey Exchange, have received approval to operate.As Hong Kong reevaluates its approach to cryptocurrency regulation, the crypto sector will hope that it strikes a balance between fostering innovation and protecting investors from fraud and market manipulation.
