Japanese financial watchdog pushes new reserve rules for crypto exchanges 

Policy & Regulation·November 27, 2025, 7:25 AM

Japan plans to require cryptocurrency exchanges to maintain reserves to cover potential losses from hacking incidents, according to a Nov. 24 Nikkei report cited by local outlet New Economy. The measure is designed to ensure that service providers can compensate users in the event of a breach.

 

Authorities are expected to set the reserve level after reviewing past hacking cases and examining how much traditional securities firms set aside. While crypto exchanges are currently required to store customer assets in cold wallets, they are not obligated to maintain any dedicated pool of funds for compensating losses, and the proposed framework is intended to close that gap.

Reserve rules mirroring brokerage standards

The Financial System Council, which operates under the Financial Services Agency (FSA), will finalize a report on the proposal and draft a bill for submission to next year’s regular Diet session. The legislation would amend the Financial Instruments and Exchange Act (FIEA). The FSA is turning to the FIEA because the reserve framework is modeled on existing rules for securities companies, which must maintain designated reserves to compensate clients for losses stemming from errors or other improper activities.

 

These measures follow earlier reports that similar requirements are being considered for third-party custody providers that hold crypto assets on behalf of exchanges. These external custodians have not been directly overseen, but the FSA now plans to require them to report their activities in advance.

 

The push to reinforce customer protections comes as Japan’s crypto market continues to expand. In a sign of that growth, mobile payment platform PayPay last week enabled transfers between PayPay Money balances and Binance Japan. The new feature allows deposits from 1,000 yen, with limits of 1 million yen per 24 hours and 2 million yen per 30 days. Until now, funding or withdrawing from Binance Japan’s spot trading services was limited to yen bank transfers or transactions through external exchanges and wallets.

 

Accumulation grows amid market pullback

Japanese companies have also continued to accumulate Bitcoin. According to Decrypt, Metaplanet, a former hotel operator that now positions itself as a Bitcoin treasury firm, said on Nov. 25 that it plans to use its Bitcoin holdings as collateral for a $130 million loan to purchase additional Bitcoin. The Tokyo Stock Exchange-listed firm currently holds 30,823 BTC and aims to expand its position to 210,000 BTC by 2027. Another publicly traded company, nail-salon operator Convano, has taken a similar approach, recently adding 97.67 BTC to bring its total to 762.67 BTC, according to BitcoinTreasuries.NET.

 

This accumulation has continued despite Bitcoin’s recent decline. The cryptocurrency has fallen nearly 20% over the past month and is now trading just below $92,000. Citing analysis from 10x Research CEO Markus Thielen and Nansen research analyst Nicolai Søndergaard, Yonhap Infomax pointed to several factors behind the pullback. Thielen highlighted $3.5 billion in outflows from spot Bitcoin ETFs this month and roughly $800 million in stablecoins leaving the market. Søndergaard noted that long-term holders have been selling, adding that such activity has historically appeared early in Bitcoin’s four-year market cycle. Bitcoin’s most recent halving occurred on April 20, 2024, roughly 19 months ago.

 

Market watches upcoming policy moves

From a broader macro perspective, Reuters reported that the Bank of Japan (BOJ) could raise interest rates as early as next month amid pressure from a weakening yen. The timing remains uncertain, with the decision seen as hinging in part on the U.S. Federal Reserve, which sets policy one week before the BOJ.

 

According to CME Group’s FedWatch Tool, markets currently assign an 84.9% chance of a 25-basis-point Fed rate cut in December. A Fed hold or a more hawkish tone could lift the dollar, further weaken the yen, and increase pressure on the BOJ to act sooner. A Fed cut, by contrast, could ease that pressure but raise questions about the U.S. outlook and the trajectory of future BOJ hikes.

 

Monetary decisions in the coming weeks are expected to influence crypto markets, as lower interest rates generally support demand for risk assets such as Bitcoin. With both the Fed and the BOJ poised to set policy in December, market participants are watching for how shifts in liquidity and currency moves could shape the next phase of digital asset prices.

Phemex halts withdraws following $37M hack

Phemex, a Singapore-headquartered crypto derivatives trading platform, has halted withdrawals following a multi-million dollar hack.Photo by GuerrillaBuzz on UnsplashHot wallet compromisedIn a message to platform users published to social media, the project stated: “To ensure security, withdrawals have been temporarily suspended while we conduct an emergency inspection and strengthen wallet services. We sincerely apologize for the inconvenience. Withdrawals will be restored soon.” In further commentary, the project apologized for the disruption, assuring service users that its mission remains to provide a trusted trading environment, while outlining that it is working on putting together a compensation plan. It added that “Our ongoing business operations are fine,” and that “trading services continue as usual.” The digital assets were removed from the platform over multiple blockchains including Polygon, Arbitrum, the Base network and BNB. Blockchain analytics firm Lookonchain itemized some of the assets that are believed to have been stolen. They include 3.48 million USDC stablecoin, 3.42 million USDT stablecoin, 841 ETH valued at $2.7 million, 110,701 LINK valued at $2.69 million, 142 billion PEPE tokens valued at $2.12 million, 1.19 million FET tokens valued at $1.45 million and 29,509 AVAX tokens valued at $1.04 million. Initial reports put the loss at $31 million. However, Web3 security firm Cyvers later claimed that $37  million covers the full extent of the loss. Following deeper analysis, it found that both Bitcoin and TRON blockchains had also been impacted, resulting in the overall loss being increased by a further $6 million. Cold wallet assets are safeThe company’s CEO Federico Variola, published a post on X advising service users that all of the assets held within the company’s cold wallets remain safe. He included a link to the Phemex proof of reserves, encouraging customers to check it. In a follow-up post, he wrote: “We are currently carefully testing our system to reprise withdrawals as soon as possible. Due to the sophistication of the threat actor we cannot rush this stage. The estimated timeline to reprise full operations is within 24h, thank you for your support.” The XNET Foundation, a non-profit entity that develops decentralized wireless networks, said that it is actively working with the Phemex team on the production of an exploit report following the incident. It added that “It has been confirmed that tokens sent to the exchange for a launchpad pool were compromised as part of this exploit.” Ongoing problemCrypto hacking remains a major concern within the digital assets sector. Blockchain security firm PackShield reported recently that $1.3 billion had been laundered from crypto hacks in 2024. That statistic demonstrates that the problem is worsening as it accounts for a $342 million or 280% increase when compared with 2023. In December a Chainalysis report found that 61% of the hacking losses suffered in 2024 implicated the involvement of North Korean hackers. It estimated crypto hacking losses of $2.2 billion for 2024, based on losses associated with 303 hacking incidents.

ZkLink Snags $10M Funding Ahead of Mainnet Launch

ZkLink Snags $10M Funding Ahead of Mainnet LaunchZkLink, a layer 2 multi-chain blockchain network project based out of Singapore, has secured $10 million in funding in advance of its mainnet launch which is scheduled for Q3, 2023.Photo by Markus Winkler on UnsplashStrategic funding roundThe Singaporean project offers a blockchain infrastructure layer that enables the ability to trade digital assets across various disparate blockchain networks. Coinbase Ventures, the investment arm of US cryptocurrency exchange Coinbase, focuses its attention on early-stage cryptocurrency and blockchain projects.That’s precisely why it has now participated in a $10 million investment in the Singaporean start-up, given that the ZkLink network doesn’t launch on mainnet for a number of months yet. Other participants in the funding round included Ascensive Assets, SIG DTI, BigBrain Holdings, Efficient Frontier, among others.In posting news of the funding to social media, ZkLink confirmed that the fresh strategic funding round has brought total funding to date to $18.5 million. “The funds raised take zkLink a step further to envision a multi-chain future with unified liquidity and seamless multi-chain user experience while remaining fully trustless and self-custodial,” the project stated.Its previous $8.5 million funding round was completed in October 2021. Among the early investors on that occasion were Arrington Capital, DeFi Alliance, Huobi Ventures, Ascensive Assets, Morningstar Ventures, GSR, Marshland Capital, Skynet Trading, ZBS Capital, and others. New York-based blockchain financing and investment platform, Republic Crypto, was the lead investor at that time.Bridging assets securely acrossZkLink uses zero knowledge technology in order to connect various layer one and layer two networks. A zero knowledge proof is the core innovation that the approach relies upon, with the proof presenting as a cryptographic technique that ensures that no data is revealed during a transaction, save for the exchange of some known value already evident to both prover and verifier.That approach makes for efficient cross-chain bridging, guaranteeing strong security without external trust assumptions. By connecting various layer one and layer two networks, zkLink claims that it empowers the next generation of decentralized trading products.Developers can access ZkLink application programming interfaces (APIs) in order to create order book decentralized exchanges (DEXs), NFT marketplaces, among other use cases. The project is harnessing zero knowledge technology to abstract away all the complexity of multi-chain trading while keeping it ultra secure and true to the ethos of crypto.A multi-chain futureWith blockchain networks being highly fragmented, the concept of a multi-chain future is one that is being increasingly embraced within the crypto space. Various projects have been launched in an effort to effect such a scenario. However, the first generation of bridging solutions have proven to be weak from a security perspective. Zero knowledge technology is seen as a potential solution to this issue.Effecting a seamless multi-chain will also bring about greater efficiencies. As a case in point, currently USDT-Ethereum and USDT-Solana exist as separate assets on distinct blockchains representing the very same USDT stablecoin. With seamless bridging, there would be no need for the duplication.In recent days, the ZkLink project team has been busy working on safety features related to securing decentralized finance protocols. In a press release associated with that work, ZkLink Co-Founder Vince Lang stated: “It is unacceptable that billions of dollars are lost each year due to custody fraud or cross-chain bridge exploits, so we encourage other DeFi protocols to conduct the same test to prove self-custody of user’s funds.”

Hong Kong's spot Bitcoin ETFs experience first daily outflows 

On Monday, Hong Kong's spot Bitcoin exchange-traded funds (ETFs) marked their first cumulative daily Bitcoin outflows, with the sole occurrence arising from China Asset Management's (ChinaAMC) ETF. ChinaAMC's spot Bitcoin ETF witnessed an outflow of 75.36 Bitcoin, while the other two ETFs reported zero inflows. This development comes after these ETFs debuted on the Hong Kong Stock Exchange on April 30.Photo by Kanchanara on UnsplashInsights into daily trading dynamics and metricsOn their inaugural trading day, the three funds garnered an inflow of 3,910 BTC, as per data from SoSo Value. However, it's important to note that shares acquired through in-kind subscriptions of physical Bitcoin are not counted as U.S. dollar-based cash flows in SoSo Value's daily net inflow statistics. Instead, SoSo Value employs the Bitcoin-inflow metric, measuring the actual flow of Bitcoin into or out of all ETFs on a given trading day. As of Monday, the combined holdings of the three ETFs stood at approximately 4,150 Bitcoin, with total net assets reaching $266.8 million from $247.7 million on the debut day, according to SoSo Value data. Farside Investors' data corroborated similar findings, indicating an outflow of $4.9 million from ChinaAMC's spot Bitcoin ETF on Monday, while the other two ETFs saw no inflows. Trading volume and market activityDespite the outflows, the total trading volume for the three ETFs surged to $8.6 million on Monday, up from $8.01 million the previous Friday, according to SoSo Value data. Meanwhile, in contrast, spot Bitcoin ETFs in the United States witnessed a net inflow of $217.06 million on the same day, with Grayscale's GBTC fund registering its second consecutive daily net inflow.
