It means that banks adjust the limits of certain businesses according to market demand, risk control and other factors. This adjustment is usually carried out according to the changes in market conditions and customer needs, aiming at better meeting customer needs and improving the bank's risk control ability. The bank's dynamic adjustment of the limit is a normal business adjustment and will not affect customers' accounts and funds. When handling related business, customers need to pay attention to abide by the bank's regulations and requirements, avoid exceeding the limit or violating relevant regulations, and avoid affecting credit records and account security.
