Chinese regional banks' investment revenue increases to 30% of total revenue due to bond trading amid a slow economy.

Chinese regional banks' investment income increased significantly during the first half of the year, with investment revenues now accounting for 30% of their total revenue. This shift comes as banks engage in bond trading due to a struggling economy and slow monetary transmission. Traditional lenders, like rural commercial banks, are placing more funds into trading bonds and assets, causing concerns of a potential bond market bubble.
