Investor risks and market reaction

Shares of companies heavily investing in crypto have seen sharp declines after earlier surges this year. Strategy Inc., which built a Bitcoin portfolio valued at approximately $66 billion, has seen its stock roughly halve since mid-July, highlighting the volatility and risks associated with corporate crypto treasuries. Retail investors holding these stocks have faced substantial paper losses, prompting calls for stronger regulatory oversight.

Balancing innovation and oversight

Exchanges across Asia are also taking a cautious approach. Hong Kong and other regional venues have resisted new listings for digital-asset treasury firms. At the same time, Japan currently counts 14 public companies holding Bitcoin, the highest number in Asia, according to Bloomberg data. JPX officials emphasize that the exchange does not prohibit corporate crypto accumulation outright but aims to ensure companies maintain proper risk management and protect shareholder interests.

Meanwhile, Japan’s Financial Services Agency (FSA) is considering a new regulatory framework that would require providers of cryptocurrency management systems to register in advance. The proposal was discussed on November 7 at a working group under the Financial System Council, an advisory body to the prime minister, signaling ongoing efforts to balance innovation with investor protection in the rapidly evolving crypto landscape.
