Final answer:
The rate that most international banks charge when they loan Eurodollars to other banks is the Euribor rate.
Step-by-step explanation:
The rate that most international banks charge when they loan Eurodollars to other banks is called the Euribor rate. Euribor stands for Euro Interbank Offered Rate, and it is the interest rate at which European banks lend Eurocurrency funds to each other. It is widely used as a reference rate for financial transactions in the Eurozone.
For example, if a bank in the United States wants to borrow Eurodollars from a bank in Europe, the interest rate they would likely pay is based on the Euribor rate.
Overall, the Euribor rate is an important benchmark for international banking transactions involving Eurodollars.
