Crude oil futures are in barrels, with one hand per 1000 barrels, and the minimum trading unit is 1 hand. Recently, the price of a barrel of crude oil has remained at around 3 10 yuan, and 100 barrel is 3 100 yuan. However, the full transaction is not required, and the Energy Center stipulates to pay a deposit of 15% of the first-hand contract value. 3 10000 yuan *0. 15%=46500 yuan. In other words, after the trading authority is opened, the deposit to be paid when placing an order is about 46,500 yuan, and the specific investment cost depends on the contract price before the transaction.

What are the characteristics of commercial banks?

1. The business objects of commercial banks are not ordinary commodities, but money and capital. The business scope of commercial banks is not in the field of production and circulation, but in the field of money and credit. Commercial banks are not enterprises directly engaged in commodity production and circulation, but enterprises that provide financial services for enterprises engaged in commodity production and circulation.

As a special kind of bank, commercial banks are different from central banks and policy financial institutions in their business nature and business objectives. Commercial banks aim at profit, and emphasize the principles of profitability, safety and liquidity in the course of operation, and are not subject to government administrative intervention. General commercial banks do not have the right to issue money, and the traditional business of commercial banks is mainly deposits and loans. Commercial banks: including China Industrial and Commercial Bank, China Agricultural Bank, China Bank, China Construction Bank, China Postal Savings Bank and Bank of Communications.

Responsibilities: Financial institutions that act as credit intermediaries through deposits, loans, remittances and savings. Commercial banks are one of the most important financial institutions, and their main business scope includes absorbing public deposits, issuing loans and discounting bills. Judging from the development of commercial banks, there are two business models of commercial banks. One is the British model. Commercial banks mainly finance short-term commercial funds, which have the characteristics of short lending period and high liquidity. That is, borrowing deposits at a lower interest rate and lending them at a higher interest rate. The deposit-loan spread is the main profit of commercial banks. This business model is relatively safe and reliable for banks. The other one is from Germany, and its business is comprehensive. Commercial banks not only finance short-term commercial funds, but also finance long-term fixed capital, that is, engage in investment banking business.
