Recently, the news that China UnionPay was fined 15.4 million yuan by the central bank for violations has aroused widespread concern in the society. The incident was like a pebble thrown into the middle of a lake, which immediately caused ripples and raised questions about the central bank's supervision. However, Kongzha98 believes that this is not due to poor regulation, but rather to the increasing supervision of the banking sector by the central bank.
In recent years, the financial markets have boomed, and the banking sector has grown in this boom. Behind the boom, however, lies a variety of irregularities and risks. In order to maintain the stability of the financial market and protect the interests of consumers, the central bank has adopted a series of strict regulatory measures to regulate and supervise the operation of the banking industry.
As a giant in domestic bank card clearing, China UnionPay's business involves the security of hundreds of millions of consumers' funds. For UnionPay's violations, the central bank's fines are necessary. This is not only a punishment for UnionPay, but also a warning to the entire banking industry, indicating the central bank's zero-tolerance attitude towards violations. 
At the same time, we should also note that the central bank's supervision is not static. With the changes in the market and the development of financial technology, the central bank's supervision methods are also constantly adjusting and improving. In the face of future market changes, the PBOC should continue to strengthen the supervision of the banking industry, improve relevant laws and regulations, and improve the efficiency of supervision. 
In short, the central bank's supervision of the banking sector must be strengthened. Only in this way can we ensure the stable and healthy development of the financial market, protect the legitimate rights and interests of consumers, and escort the sustainable development of the economy.
