Financial institutions should reasonably and prudently determine the financing period when handling peer supervision. Among them, the longest term of interbank lending business shall not exceed 3 years, and the longest term of other interbank financing businesses shall not exceed L years, and shall not be extended after expiration. The regulatory authorities only stipulated the deadline requirements for five types of interbank financing business, but not for interbank investment business. Financial institutions should adhere to the principle of prudence and reasonably determine the term.
