Interest Basis

Interest Basis is an important term in international trade finance and settlement, referring to the time basis or day-count convention used when calculating interest. Common interest bases include Actual/360, Actual/365, and 30/360, and different bases can lead to differences in interest amounts. It is commonly used in businesses such as bill negotiation under letters of credit, forfaiting, factoring, and bank collection financing, and banks and customers need to specify it clearly in agreements. Points to note: first, the interest basis must be confirmed in writing with the counterparty to avoid disputes arising from different rules; second, pay attention to the conventions of different currencies and markets, such as USD often using Actual/360, while GBP commonly uses Actual/365; third, the interest basis usually determines the final interest together with the interest rate and interest period. Difference from other terms: the interest basis focuses on 'how to calculate the number of days,' rather than the type of interest rate (fixed/floating) or the interest calculation cycle (monthly/quarterly). Foreign trade practitioners should specify this clause in contracts to accurately calculate financing costs.
