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.

Turkish lira becomes third largest fiat currency in crypto trading

The Turkish Lira (TRY) has become the third largest fiat currency by volume in the cryptocurrency market, according to a report by Kaiko. This milestone was reached as TRY's share of the crypto market hit an all-time high of 19% in early June. The increase in volume is attributed to the country's economic challenges, notably its high inflation rate, which has surpassed 70%, making the lira one of the most volatile fiat currencies globally.Photo by Afdhallul Ziqri on UnsplashFactors influencing the increaseThe shift in the Turkish lira's position in the crypto market is partly due to increased foreign exchange volatility and currency devaluation, common catalysts for cryptocurrency adoption in developing economies. Additionally, geopolitical factors such as a record number of elections and diverging monetary policies have intensified market fluctuations. This environment has favored cryptocurrencies like Bitcoin, which reached new highs against the lira in recent months. For instance, Bitcoin escalated to 2.3 million TRY in March from 979,000 TRY in October 2023. The recent adjustments in cryptocurrency trading platforms, particularly Binance's delisting of certain fiat trading pairs due to banking issues, have also increased the dominance of TRY in crypto transactions. This series of events underscores the growing interconnection between traditional and digital finance markets, highlighting the increasing role of cryptocurrencies in regions facing economic instability.

Boyaa Interactive Greenlights $5 Million Investment in Bitcoin and Ether

Boyaa Interactive Greenlights $5 Million Investment in Bitcoin and EtherBoyaa Interactive International Limited, a Hong Kong-based investment holding company with a track record in developing online chess, card, and puzzle games, has made a strategic move with a proposed investment in digital assets.The company’s board of directors has recently given the green light for the allocation of a substantial budget amounting to $5 million for the purpose of acquiring cryptocurrencies.Photo by Traxer on UnsplashWeb3 positioningThe Chinese company, incorporated in the Cayman Islands, announced the move as Boyaa Interactive seeks to position itself for a dynamic shift into the realm of Web3.While the exact allocation breakdown was not detailed in the disclosure, the company outlined that its primary focus would be on procuring established cryptocurrencies, specifically Bitcoin (BTC) and Ether (ETH). Boyaa Interactive intends to execute these purchases through regulated and licensed trading platforms within the upcoming year.In a letter addressed to its shareholders and potential investors, the company emphasized the strategic nature of this decision:“The purchases of cryptocurrencies are for the consideration of the Group’s future business layout into the field of Web3. The Board is of the view that the purchases of cryptocurrencies (including mainly Bitcoin (BTC) and Ether (ETH)) by the Group are in the interests of the Company and its shareholders as a whole.”A challenging recent historyThe move towards cryptocurrencies is a significant pivot for Boyaa Interactive, a company that has navigated a series of challenges in recent years. In 2018, the company’s Chairman and CEO, Zhang Wei, faced legal troubles and was sentenced to 12 months in prison for bribery, which led to his resignation from all executive and management positions.Subsequent restructuring saw Dai Zhikang stepping in as the new Chairman of the board, while Tao Ying assumed the role of an Executive Director and Chairman of the Nomination Committee.Financially, Boyaa Interactive experienced a tough period marked by revenue contraction. The company reported revenue declines over the course of 2018, largely attributed to a governmental crackdown on online poker applications and the discontinuation of poker as a recognized competitive sport. Regulatory risks stemming from the Chinese government’s stance on Texas Hold’em poker games resulted in a substantial falloff in revenue by comparison with past performance.Funds seizureThese challenges cascaded into the following year, when the company encountered a substantial freeze on its funds. In 2019, a Chinese court ordered the freezing of RMB 635 million (approximately $88.6 million) belonging to Boyaa Interactive, following the legal actions against Zhang Wei and his associated entities.One of the company’s subsidiaries, Boyaa Shenzhen, was found guilty of offering bribes. The company responded by clarifying that the frozen funds could potentially be confiscated if linked to Zhang’s misconduct. However, Boyaa Interactive also stressed that it had not been directly implicated in the case, thus mitigating the legal risks to the broader organization.Amidst these adversities, Boyaa Interactive’s decision to invest in cryptocurrencies demonstrates its openness to adapting to changing technological landscapes and exploring new opportunities in Web3.

HashKey on-boards market makers to boost liquidity

HashKey on-boards market makers to boost liquidityHashKey, a licensed crypto exchange in Hong Kong, has unveiled plans to onboard individual and enterprise market makers to enhance liquidity on its platform.Photo by engin akyurt on UnsplashMarket maker programIn an announcement on Tuesday, the exchange disclosed that interested parties, whether individuals or entities, can apply to become market makers on HashKey. To qualify, applicants need to engage in cryptocurrency trading worth a minimum of $5 million per month on the exchange.The exchange outlined that the program aimed to “recognize and incentivize users actively contributing to the liquidity” of the platform.Upon submitting their business plans for review, successful applicants will be invited to enter into a contractual agreement with the exchange’s due diligence team, commencing trading activities from Dec. 28 onwards when the program goes live.Commission free tradingThe exchange aims to encourage liquidity providers by offering a commission ranging between 0.005% and 0.015% of the transaction value, determined by monthly rankings or trading volumes, falling within a tiered structure set out within the program. Market makers demonstrating a trading volume of at least $100 million per month stand to enjoy the highest tier of commission revenue. Notably, all market makers will be exempt from commission fees on their trades.Market makers who participate via the program will be on trial for an initial two-month period. Those who are participating in market maker programs on other platforms currently will be able to avail of equivalent trial fee rates through the HashKey exchange.Service expansion trendThe move by HashKey follows a broader trend in Hong Kong, where regulated exchanges have been expanding their services and forming strategic partnerships since the issuance of the first licenses in August. In a recent development, OSL, another Hong Kong licensed exchange, collaborated with Interactive Brokers on November 28, enabling Hong Kong clients to buy Bitcoin through Interactive Brokers’ investment accounts.Additionally, on November 30, OSL welcomed Victory Securities for crypto trading services on its platform. That move came about following Victory’s acquisition of a retail crypto trading license some days beforehand. Notably, OSL received a $90 million investment from blockchain entity BGX in November.While HashKey has been extending its altcoin offerings, exclusively available to accredited investors meeting a $1 million portfolio requirement, the exchange has been proactive in enhancing user security. On Nov. 16, the platform introduced comprehensive insurance coverage for users’ and enterprise assets stored within its digital wallets in collaboration with fintech firm OneDegree.Earlier this week, it emerged that the platform had experienced an unprecedented surge in daily trading volumes. The surge had been attributed to a token rewards program that the exchange is currently running, that offers the distribution of HSK tokens or EcoPoints.As HashKey opens its doors to market makers, the move is poised to contribute to increased liquidity on the exchange, aligning with the broader trend of Hong Kong’s regulated crypto exchanges expanding their offerings and forming strategic partnerships.
