Chinese regulators investigate bond price manipulation in Jiangsu's regional banks and halt large-scale bond buying.

Chinese regulators are investigating regional banks, including four in Jiangsu province, for suspected bond price manipulation amid an extended rally in Chinese government bonds. Concerns of a potential bond market bubble and financial instability have prompted the central bank to instruct rural lenders in Jiangsu to halt large-scale bond buying. Regulators have also reportedly required mutual funds companies to limit bond fund duration to two years.
