Regulator in Tokyo moves to ban insider trading in crypto market

Policy & Regulation·October 17, 2025, 8:11 AM

Japan’s Financial Services Agency (FSA) plans to ban insider trading in the cryptocurrency market, according to an Oct. 15 report in Nikkei, cited by CoinPost. The forthcoming rules would amend the Financial Instruments and Exchange Act to explicitly bar trading based on nonpublic information, with violators subject to administrative fines.

Tightening oversight through the SESC

The FSA intends to hammer out the details through a working group by year’s end and aims to submit a bill amending the securities law during the 2026 ordinary session of the Diet. Under the proposal, the Securities and Exchange Surveillance Commission (SESC) would gain authority to investigate suspected violations and could recommend fines or criminal charges in cases of alleged insider trading.

 

Experts say Japan’s system of self-regulation, led by cryptocurrency exchanges and the Japan Virtual and Crypto Assets Exchange Association (JVCEA), lacks sufficient data monitoring. The government hopes that granting the SESC oversight of crypto transactions will help ensure fairer trading and make the market more attractive to investors.

 

The new rules would target the use of confidential information, such as advance knowledge of a token listing or a major security flaw. Yet applying insider-trading standards to crypto may prove difficult. Many tokens have no clear issuer, making it harder to determine whose information could move markets or who should be held accountable.

 

Crypto investing has surged in Japan, with domestic trading accounts quadrupling in five years. The FSA now aims to update its rules to reflect that digital assets are traded mainly as investments, not as payment instruments.

 

Leadership transition brings policy uncertainty

Japan’s plan to strengthen oversight of cryptocurrencies coincides with a period of political transition. Prime Minister Shigeru Ishiba has announced his intention to step down but remains in office for now. According to CNBC, Sanae Takaichi, newly elected president of the ruling Liberal Democratic Party (LDP), would typically be expected to assume the premiership, but the coalition’s collapse has upended what would otherwise be a routine transition. The parliamentary vote to choose Japan’s next leader, initially slated for Oct. 15, has been postponed to Oct. 21.

 

In the wake of the split, the main opposition Constitutional Democratic Party (CDP) is reportedly seeking Komeito’s support for a joint prime ministerial candidate. Yuichiro Tamaki, leader of the Democratic Party for the People (DPP), is seen as a potential consensus choice. The ruling LDP currently holds 196 seats in the lower house, but a united opposition could command a larger bloc.

 

Tamaki has also drawn attention in crypto circles. About a year ago, he proposed cutting taxes on cryptocurrency gains to 20%, a flat rate similar to that on stock profits, during his campaign against Ishiba. At present, crypto gains in Japan are classified as miscellaneous income and taxed at progressive rates that can exceed 50% when local levies are included.

 

Metaplanet’s Bitcoin strategy tested amid market shifts

Against that backdrop, Metaplanet, often dubbed Japan’s answer to the U.S. firm Strategy for its aggressive Bitcoin (BTC) accumulation, is under pressure as its valuation slips below the value of its crypto holdings. The company’s market-to-BTC net asset value (mNAV) ratio fell to 0.99 on Oct. 14, dropping below 1 for the first time. The metric compares the company’s market value with its BTC holdings, and a reading below 1 means the stock is trading at a discount to its BTC reserves.

 

The decline comes after Metaplanet paused BTC purchases for the past two weeks. As of Oct. 1, the company held 30,823 BTC on its balance sheet.

Singaporean VC Pledges Funding for Web3 Accelerator

Singaporean VC Pledges Funding for Web3 AcceleratorSingaporean crypto investment venture capital firm, Foresight Ventures, has committed to doubling down on funding a Web3 Accelerator.Back in November, the firm launched Foresight X, a Web3-focused incubator program. At the time, it committed to allocating $10 million to be divided between three categories of Web3-centric projects and collaborations. Fast forward six months and the firm is now committing to stump up an additional $10 million in funding for the project.Categories include ecosystem projects, research grants, and an eight-week incubator program which was initially offered to thirty early-stage projects. In that initial funding round, start-ups were being supported with funding of $50,000, up to a maximum of $200,000.Photo by Shubham Dhage on UnsplashSecond phaseThe project is now entering its second phase, accepting applications once again from a new round of start-up applicants. In this instance, the focus will move towards Web3 projects with an emphasis on artificial intelligence (AI), zero-knowledge cryptography, bitcoin, non-fungible tokens (NFTs), machine learning, and liquid staking derivative products.With second-round funding, each selected project will be funded to the tune of $200,000 rather than the funding range of $50,000 to $200,000 employed on the first phase. Additionally, up to three mentors will be assigned to each successful applicant project. On top of that, one fund partner from Foresight Ventures will be assigned to each start-up in order to provide them with a steer towards growth and development. The program will culminate with a Demo Day, facilitating each project to showcase their service or product offering.Bitget partnershipFounded in 2020, Foresight Ventures has progressed in a short space of time, from having $80 million assets under management (AUM) to an AUM of $400 million today. The venture capital outfit is led by seasoned venture professionals with backgrounds in companies like Google, Bitmain and Sequoia Capital.Among its leading investments is SEI, the layer one blockchain project that is optimized for transaction speed and throughput. In April, the company committed $50 million towards SEIs $120 million ecosystem fund. In January, it invested $15 million in Singapore-based digital asset infrastructure and market making firm, CyberX.Last month the firm partnered with crypto derivatives trading platform Bitget in contributing towards its Asia-focused Web3 fund. Focused on funding outstanding Web3 projects in the region, Bitget has put together a $100 million fund. Foresight Ventures joined Dragonfly Capital, SevenX Ventures, DAO Maker and ABCDE Capital in expressing interest in investing in the fund, ultimately investing and partnering with Biget on the initiative.The firm has come a long way in a short space of time, signaling its intent in March 2022 when it committed to investing up to $200 million in Web3 start-ups and blockchain projects over the course of three years. Other key Foresight Ventures portfolio companies include Singapore-based digital assets financial services firm, Matrixport, and metaverse developer Everyrealm. Aside from its headquarters in Singapore, the firm also maintains a presence in Shanghai, allowing it the reach to cover crypto-related projects throughout the Asian region.

Poly Network Exploit Results in Billions of Nonexistent Tokens

Poly Network Exploit Results in Billions of Nonexistent TokensPoly Network, the China-based interoperability platform, was targeted by hackers over the weekend in a major attack that resulted in the creation of billions of tokens out of thin air. It’s the second time in as many years that the cross-chain bridge has been exploited by hackers.The attacker exploited a vulnerability in Poly Network’s cross-chain bridge tool, allowing them to generate a substantial number of tokens that previously did not exist, as reported by Arhat, the Founder of 3z3 Labs, on Twitter.Photo by Shubham Dhage on UnsplashNetwork suspensionThe Shanghai-based project team behind Poly Network promptly informed its users on Sunday that its services were temporarily suspended due to the attack. The platform assured its users that it was diligently assessing the extent of the breach and the impact on assets. They emphasized their commitment to safeguarding users’ assets and urged everyone to remain calm.The hacker, at one point, held nearly $43 billion worth of cryptocurrency in their digital wallet, according to DeBank, a decentralized finance portfolio tracker. This staggering figure was corroborated by PeckShield, a blockchain data and security firm.Bridge vulnerabilitiesBridges play a crucial role in the Web3 ecosystem, enabling users to transfer assets across different networks. However, they have often been attractive targets for hackers. In this attack on Poly Network, the hackers issued themselves nearly 100 million BNB and $10 billion worth of BUSD, the Binance-branded stablecoin, on the layer-2 network Metis, revealed Colin Wu, a Chinese crypto journalist.Similarly, on the Heco network, approximately 100 trillion units of the dog-themed meme coin, Shiba Inu, were created. Additionally, a significant number of altcoins were generated on Polygon and Avalanche networks.Illiquid Metis tokensMetis clarified that the BNB and BUSD tokens issued on its network by the hackers are effectively worthless since there is no available sell liquidity. Poly Network also locked these tokens, ensuring they cannot be utilized. Arhat of 3z3 Labs acknowledged that the impact of the Poly Network attack was somewhat mitigated by the lack of liquidity, which prevented the hackers from realizing substantial gains on Metis.However, on other networks like Ethereum, the stolen tokens were exchanged on decentralized exchanges. Arhat estimated that the attacker managed to convert only a small portion of the tokens, amounting to approximately $400,000 worth of crypto, while the remaining tokens lacked liquidity and were essentially worthless.SlowMist, a blockchain security firm, suggested that the hacker’s total gains were higher. They reported that over $4 million worth of digital assets from the attack had been cashed in, including 1,500 Ethereum worth $3 million and 93 billion SHIB worth $700,000.Poly Network had previously made headlines in 2021 when it experienced a historic attack, considered the largest exploit in decentralized finance at the time. The project suffered a loss of $600 million as funds were siphoned away from Ethereum, Binance Smart Chain, and Polygon. However, the hacker eventually returned $342 million worth of stolen crypto, and Poly Network took steps to repay affected users.

BitGo CEO Emphasizes Separation of Trading and Custody to Prevent Crypto Bankruptcies

BitGo CEO Emphasizes Separation of Trading and Custody to Prevent Crypto BankruptciesMike Belshe, Founder and CEO of digital asset trust company BitGo, emphasized the importance of separating cryptocurrency trading and custody to prevent incidents similar to those involving Mt. Gox and FTX in his keynote speech at Impact, the main conference of Korea Blockchain Week (KBW) 2023.Established in 2013, BitGo is currently the world’s largest provider of virtual asset custody services, serving more than 1,500 institutions in over 50 countries, including the US, Switzerland, and Germany. Major exchanges like Bitstamp, Korbit, Bullish, Gate.io, and Crypto.com entrust BitGo with safeguarding their virtual assets.Clear divisionDuring his speech, Belshe repeatedly stressed the need for custody services for the sustainability of the virtual asset ecosystem, asserting that separating trading and custody can enhance trust in the industry and attract traditional financial institutions.Unlike stock markets, where payment institutions and custodians are separate entities, this kind of separation does not exist in the virtual asset market. To steer traditional financial institutions toward the virtual asset ecosystem, this issue needs to be addressed, Belshe said.He went on to cite the Mt. Gox hack in 2014 and the FTX collapse last year as examples that underscored the importance of virtual asset custody. Mt. Gox, once the world’s largest Bitcoin exchange, reportedly lost some 650,000 to 850,000 Bitcoins — worth more than $450 million at the time — due to a hacking incident, leading to its bankruptcy. FTX also faced insolvency after it was revealed that it inflated its assets using its native token FTT and that its management was misusing customer investment funds.Photo by Melinda Gimpel on UnsplashBelshe suggested that when Mt. Gox employees discovered the Bitcoin theft during the hack, it was already too late. If custody had been treated separately, the theft could have been detected much faster. Regarding the FTX debacle, he argued that even with just a few auditors, the problems in that situation could have been apprehended. FTX’s ability to provide custody of customer assets themselves led to unauthorized activities, including cross trading and insider trading, ultimately resulting in the misuse of customer funds.Korea’s favorable conditionsBelshe also assessed that South Korea is well-positioned for the establishment of virtual asset custody systems due to its high trading volume and a solid commitment to drafting crypto-related legislation. Seven such bills are currently underway, reflecting the authorities’ determination to address problems in the ecosystem. Korea thus has the potential to establish itself as a hub in Asia, he said.Indeed, BitGo’s partnership with Hana Bank to establish a joint venture for digital asset custody services in Korea is driven by these factors. Through its entry into Korea, BitGo aims to share its extensive knowledge and experience in digital asset business institutionalization and investor protection. It will also apply the expertise and strategies it has accumulated through close communication with regulatory authorities and supervisory agencies in various countries, including the US, to support the integration of virtual assets into the regulated framework in Korea.Belshe commented that through this partnership, BitGo will seek to enhance its understanding of Korea and utilize its technology and expertise to boost confidence in the Korean cryptocurrency market.
