What is Reference Rate?
A reference rate is a benchmark exchange rate that a recognised body publishes at a fixed time, so that businesses, banks and regulators can all point to the same number. In India, reference rates for the rupee against major currencies such as the US dollar, euro, pound and yen were historically published by RBI. Since 2018, that job has been done by Financial Benchmarks India Ltd (FBIL), which publishes rates on business days.
A reference rate is not a rate anyone actually trades at. It is a published snapshot, useful for valuing transactions, settling contracts and converting figures in a consistent way.
Why it matters for exporters
When you convert a foreign-currency invoice into rupees, you need some rate, and a published reference rate gives you an objective, verifiable choice. Accounting teams often use it to record foreign-currency invoices in the books. It can also help when you fill field 1.22 of the EDF, the total value in INR in figures and words, though our fact sheet does not specify which rate to use there, so confirm with your AD bank whether it prefers a reference rate, its own card rate or something else.
The rupees you actually receive will usually be lower than the reference rate implies, because your bank applies its own buying rate and markup when it converts your inward remittance. Expect that difference and record it as an exchange gain or loss.
Example
Tejas Analytics Pvt Ltd raises an invoice for EUR 5,500 on 16 November 2026. Its accounts team records it using the published reference rate for that date, say ₹91.20 per euro, giving ₹5,01,600 (rate illustrative). For its November EDF, it asks its bank which rate to use for field 1.22. When the client pays in January, the bank converts at its own buying rate, and the difference goes to the exchange fluctuation account.
Common confusion
A reference rate is not the rate on your FIRA, which is the bank's actual conversion rate. Compare exchange rate, and see exchange rate for GST on export invoices for the tax angle.
