CBRC issued a notification which requires all trust companies to start running self-examinations on business compliance. Local banking regulatory bureaus need to more tightly monitor regulatory compliance, the newspaper reported.

According to the notification, local banking regulatory bureaus are also responsible for urging trust companies to be cautious when picking candidates and expanding their property-related businesses

One CBRC representative noted that trust firms' property-related businesses have been closely monitored by the commission. CBRC will actively implement national real estate control measures and strengthen supervision over such businesses based on the country's macro policies and economic development.

Retures said the China Banking Regulatory Commission instructed trust firms to assess the risks posed by their portfolios in November in a move to rein in the red-hot property market. Since then, some local trust companies have halted property-related loans.
