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.

HashKey Gears Up to Offer Trading Service to Retail Traders

HashKey Gears Up to Offer Trading Service to Retail TradersHashKey is gearing up to launch its services to retail traders in Hong Kong with the intention of offering them Bitcoin and Ether trading products initially.The Hong Kong-based digital asset management platform received full licensing approval from the local regulator, the Securities Futures Commission (SFC), earlier this month. It’s anticipated that the platform will launch to retail on August 28.That’s according to a report from a local media source earlier this week. Financial publication Investing.com stated: “General investors in the period can only trade Bitcoin (BTC) and Ethereum (ETH), because these two currencies currently account for most of the trading volume in the market.“It’s worth noting, however, that investors will be subject to a cap, permitted to allocate only up to 30% of their net worth into the realm of cryptocurrencies while utilizing the platform.Photo by Traxer on UnsplashServing retail clientsIt’s a significant milestone for both HashKey and the regulator, given that Hong Kong has been making huge efforts to further the development of digital asset innovation within the Chinese autonomous territory over the course of the past twelve months. Hashkey, alongside brokerage and exchange business OSL (also successful in obtaining a license), has been collaborating with regulators from an early stage in the lead-up to both receiving full licensing.HashKey got to this point by focusing on two pivotal licenses offered by the SFC. The first of these licenses, known as Type 1, paved the way for HashKey to initiate a virtual asset trading platform, aligning seamlessly with the regulatory framework laid out under Hong Kong’s securities laws. The second license, Type 7, empowers the crypto platform to furnish automated trading services to both institutional and retail clientele.Nurturing digital asset innovationHong Kong has maintained a resolute focus on cultivating a crypto-friendly environment within its borders in 2023. Echoing this sentiment, Financial Secretary Paul Chan asserted the government’s and regulatory bodies’ determination to incubate a robust crypto and fintech ecosystem throughout the year.By March, over 80 crypto enterprises signaled their intent to establish a presence in Hong Kong, with several major players in the crypto industry among them. In April, the Hong Kong Monetary Authority (HKMA) issued a call to banks, urging them to extend their services to cryptocurrency companies.Banking remains a difficulty in Hong Kong for crypto businesses despite the HKMA’s efforts. However, in the case of both HashKey and OSL, both are being banked by Hong Kong’s largest virtual bank, ZA Bank.In May, the HKMA unveiled a comprehensive licensing framework tailored for crypto platforms, imposing a deadline of June 1 for compliance. As August rolled in, a select few crypto platforms clinched the green light to offer crypto trading services to an eclectic client base encompassing both retail and institutional participants.This regulatory framework, designed to safeguard the interests of investors, is playing a large part in Hong Kong’s recent success in developing the sector. In this particular instance, it will mean that retail traders will be granted access to Bitcoin and Ethereum exclusively. This curtailed selection provides a good starting point for retail trading, and it’s likely that we will see HashKey’s trading offering being extended to cover additional digital assets as soon as local regulators permit it.

Korean crypto exchange Upbit launches BTC-ETH Duo Index

Dunamu, the operator of South Korea’s leading crypto exchange Upbit, announced today that it launched a new crypto price tracking service, Bitcoin-Ethereum Duo Index (Duo Index). The news was reported by the local media outlet Etoday.  The service tracks the two most prominent tokens, Bitcoin and Ethereum, each being the top performer and the runner-up in terms of market capitalization in the crypto asset market. It is a strategy index that equally weights Bitcoin and Ethereum, with their holding ratio updated to 1:1 every month. The weightings of the two cryptocurrencies in the index are subject to an adjustment factor, which is based on their prices. The BTC-ETC Duo Index is currently available on the Upbit Cryptocurrency Index (UBCI) website. Photo by Markus Winkler on UnsplashThe Federal Reserve’s approval of spot Bitcoin ETFs in January has drawn significant attention from many investors, driving up the prices not only of Bitcoin but also Ethereum. Dunamu explained that this heightened interest surrounding Bitcoin and Ethereum is the reason behind its launch of the Duo Index. New tool to boost crypto portfolio’s performance Referencing the Duo Index can help investors estimate their own crypto assets portfolios and boost their performances based on the indicators it offers, including the winning rate of the two coins combined.   The current winning rate of the Duo Index stands at over 58%, which is three percentage points higher than that of the Upbit Market Index (UBMI), which tracks not only Bitcoin and Ethereum but also other altcoins. The high winning rate of the Duo Index demonstrates the bullish sentiment surrounding the two top coins. A Dunamu official stated that the company will continue to keep up with the crypto market trend and further release other strategy indices that would serve the emerging needs of the investors.

Korean crypto exchanges to face new crypto accounting standards

As the Virtual Asset User Protection Act is set to take effect in July, South Korean virtual asset services providers (VASPs) are preparing themselves for new crypto accounting standards. This development is pushing crypto businesses to take consultation services from accounting firms, local media outlet Yonhap Infomax today reported.  Pronounced last year, the new crypto accounting guideline is scheduled to be applied to VASPs starting this July. Rather than providing clear and explicit standards, the guideline requires crypto businesses to interpret it on their own based on “reasonable grounds.” One accountant in the crypto industry said that individual crypto exchanges are wrapping their heads around the new crypto accounting standards, pondering over numerous issues such as whether to manage customer assets in a single record-keeping system. Photo by Volkan Olmez on UnsplashThe most significant concern among VASPs is that the new standard will highly likely recognize crypto assets entrusted by customers as either assets or liabilities. So far, local crypto exchanges haven’t recognized custodial tokens as assets; instead, they have been including these tokens in the footnotes. Only the money users deposited in Korean won has been acknowledged as “customer deposit liabilities.” Dunamu, the operator of crypto exchange Upbit, stated in the footnotes of its previous quarterly report that virtual assets entrusted by customers do not meet the accounting definition of an asset, leading the exchange to exclude its users’ custodial tokens from the asset category.  Varying interpretation of ‘control over custodial assets’ A lot is at stake depending on how individual crypto exchanges interpret the new guideline. If crypto exchanges are deemed to have control over custodial assets, they must meticulously document the details of the assets in custody on their financial statements, including the total amount of custodial assets and how they are managed under what policies.  These details would serve as decisive factors in determining who bears the liabilities in the event of future incidents.  Crypto businesses’ accounting dilemmaThe Korean financial regulators have explained that the new guideline is not the ultimate golden rule, implying that there could be a leeway for crypto businesses if they have reasonable grounds for not following the new accounting standard. However, regulators said they will conduct thorough examinations on the financial statements following their publishment, to ensure that custodial assets are not left out in the documents. This is where VASPs face a difficult choice between two different options; they can either classify custodial tokens as something other than an asset and undergo thorough examinations, or they can recognize them as an asset and risk being included in the “mutual investment-restricted group.” This is a group consisting of large local firms with over nearly KRW 10 trillion ($7.5 billion) in total assets. The companies listed in the group are subject to strict government regulations.  Previous recognition of Dunamu as ‘big firm’ raises concerns among VASPsThe local regulatory authority previously classified Dunamu as part of the mutual investment-restricted group in 2022.  At the time, Korean won deposits made by Upbit users, categorized under the customer deposit liabilities, were recognized as part of its assets by the Korea Fair Trade Commission (KFTC). The KFTC determined that Dunamu had controlling power over the customers’ deposits. This judgment by the KFTC led the company to fall under the mutual investment-restricted group. Once the new accounting standard takes effect in July, the likelihood is that the exchange’s custodial tokens, currently valued at KRW 20.2 trillion, will also be recognized as assets. Meanwhile, another prominent crypto exchange Bithumb is reported to have KRW 4.5 trillion in total assets.   Another accountant in the crypto industry expressed concerns, saying that VASPs will have to deal with more regulations if incorporated into the mutual investment-restricted group. The person added that recognizing custodial tokens as assets could further heighten the management risks for crypto businesses.
