Non-standard business of investment banks refers to the unstructured financing business of investment banks, that is, a business form that uses financial instruments to operate capital, which is different from the traditional securities and bonds business. This business includes various forms of derivative transactions, such as interest rate, exchange rate, commodity futures and other derivative contracts, as well as complex businesses such as equity financing and asset securitization. The non-standard business of investment banks usually requires a lot of professional skills and financial engineering knowledge, and also puts forward extremely high requirements for risk management.

The non-standard business of investment banks is usually set up to meet the individual needs of customers. Because the risks and benefits of traditional stock and bond business are relatively stable, the transaction costs and benefits are usually standardized in stock and bond transactions. Non-standard business is different, and its risks and benefits are very variable, which means that customers can choose the corresponding risks and benefits according to their investment needs. The flexibility and personalized characteristics of non-standard business of investment banks have enhanced investors' trust and loyalty to investment banks to some extent.

Compared with the traditional business, the non-standard business of investment banks has higher profits, but also greater risks. In order to ensure that the risk of non-standard business can be controlled, investment banks need to establish a corresponding risk management system, set up a special non-standard business transaction team, and conduct refined transaction, risk, assets and capital management. In addition, investment banks need to pay attention to compliance to ensure that their business conforms to market supervision regulations. In short, the non-standard business of investment banks is both a challenge and an opportunity for financial institutions. For investors, we should have corresponding risk awareness and do a good job in risk assessment and control.
