Block Trades Surge in Japan as Firms Shed Cross-Holdings to Meet Reform Goals
Japan's stock market is experiencing a surge in block trades as companies continue to streamline cross-shareholdings to meet corporate governance reforms. These private transactions, which bypass traditional public offerings, reached a record ¥1.3 trillion ($8.3 billion) this year. Toyota Motor Corp. and Daiichi Sankyo Co. have been among the most active participants in these trades.
Regulators and corporate leaders alike have been pushing for greater transparency and efficiency in how firms manage their stakes in one another. The rise of block trades reflects a strategic shift to faster and more flexible divestitures, particularly in light of heightened market volatility. Bankers cite this volatility, fueled by trade tensions with the U.S. and concerns over fiscal policies of newly elected leaders, as a key driver.
The increased use of block trades also stems from the dwindling pipeline of large secondary offerings. Many cross-shareholdings deemed suitable for public sales have already been offloaded over the years, leaving firms with smaller, residual stakes that are more efficiently handled through block trades. This trend has been reinforced by the ability to quickly target specific investor groups without the need for a lengthy prospectus process.
Why Block Trades Are Gaining Ground
Block trades offer a streamlined alternative to traditional stock sales. Companies can easily designate a group of investors without the complexities and delays of a public offering. This flexibility is especially valuable in a volatile market environment where timing is critical. Naohiko Yatsuda of Mitsubishi UFJ Morgan Stanley Securities Co. highlights that the attraction lies in the ability to target long-only investors, a segment with strong demand.
The Topix Index has shown 30-day volatility of 17%, higher than the 15% seen in the MSCI AC Asia-Pacific index and 13% for the S&P 500. Such volatility makes it harder to execute traditional follow-on offerings at favorable times. As a result, block trades have become a preferred method for firms to meet regulatory and corporate governance goals.
What This Means for Japan's Markets
The surge in block trades signals broader progress in Japan's corporate governance reforms. Regulators have long criticized cross-shareholdings for creating conflicts of interest and shielding management from accountability. By reducing these stakes, companies are aligning more closely with international standards and improving transparency.
This shift has broader implications for the Japanese equities market. As more firms adopt these practices, the market is likely to become more liquid and attractive to global investors. Yusuke Sakamoto of Mizuho Securities Co. notes that the increase in block trades marks one of the largest shareholder restructuring efforts in corporate Japan.

Moreover, the government has called for greater transparency in why companies hold stakes in peers. This has added another layer of pressure on firms to justify and disclose their cross-shareholding practices. The result is a more open and accountable corporate environment, which supports long-term investor confidence.
Analysts Eye Market Flexibility
Analysts are watching how firms continue to utilize block trades in the face of ongoing volatility. Yusuke Minowa of Goldman Sachs Japan Co. points out that block trades allow companies to offload shares quickly, a crucial advantage in unpredictable markets. This flexibility has led to an increase in demand from global investors, who are eager to capitalize on these opportunities.
Daiichi Sankyo Co. has been a key example of this trend. Shareholders including Custody Bank of Japan Ltd., SMBC Trust Bank Ltd., and Mitsui Sumitomo Insurance Co. executed a series of block trades worth ¥188 billion in August. These transactions took place after the stock reached a six-month high, indicating a strategic approach to capital management.
As Japan continues its corporate governance reforms, the increased use of block trades is likely to remain a key feature of the market. The combination of regulatory pressure, market volatility, and investor demand has created a favorable environment for firms to adopt these efficient and transparent methods of divesting stakes in peers. This trend could help position Japan's equity market as a more attractive and dynamic destination for global capital in the years ahead.
