Bank of India Forex Rates Explained | How to Save on Transfers

Bank of India (BOI) does not use one exchange rate. It publishes a forex rate sheet each working day and revises it as the market moves.

When money reaches you from abroad, BOI applies its TT (telegraphic transfer) buying rate, which sits below the live mid-market rate. That gap, the margin, is where most of the cost hides, and it is separate from the fees and the 18% GST on the conversion.

If you are an exporter or freelancer receiving payments, the TT buying rate on your credit advice decides your rupee payout, not the rate BOI advertises.

If you receive export income regularly, you can collect international payments at the live mid-market rate and keep more of each invoice. This guide covers how BOI sets each rate, what a transfer really costs, and how the maths compares.

A "forex rate" is the price of one currency in another at a given moment. Banks quote it against the interbank rate, the wholesale price at which large institutions trade, then add a margin before passing it to you.

BOI publishes four rates because each transaction type carries a different margin. If you want the plain-English version of how these numbers are built, start with forex rates.

The rates BOI shows are indicative. The rate that actually applies is the one prevailing when your account is credited, so a morning figure can shift by the time your transfer settles.

TT stands for telegraphic transfer, the electronic movement of money between banks across borders. BOI quotes four rates you will see on its sheet.

• TTB (TT buying): the rate at which BOI buys foreign currency from you and pays out rupees. This applies when you receive an inward or export remittance.
• TTS (TT selling): the rate at which BOI sells you foreign currency, used when you send money out.
• TCB and TCS (travel currency buying and selling): used for the travel card and foreign cash, wider than the TT rates.

For anyone receiving export income, the TTB rate is the number that matters. A telegraphic transfer is the default rail behind most bank-to-bank inward payments. Here is an illustrative snapshot (as of July 2026).

The mid-market rate that day is around ₹89.40, so every BOI rate sits a margin away from it.

The exchange-rate margin is the largest cost, but not the only one. As of July 2026, the fees an exporter or freelancer is likely to meet are set out below.

Receiving money still carries a processing fee plus the rate margin, and a correspondent bank can deduct its own charge before the money reaches BOI.

Banks revise these schedules periodically, so verify the current numbers on BOI's own forex service-charges page before you rely on a figure.

Other public sector banks price inward transfers the same way. For comparison, see how Indian Overseas Bank forex rates stack up against the mid-market rate.

Two BOI features are worth knowing, because they change the cost picture.

Multi-Currency Prepaid Card: BOI offers a prepaid card you can load with foreign currencies for travel and overseas spending. When you spend in a currency already loaded, there is no markup; an unloaded currency triggers a cross-currency conversion on the fly.

FX-Retail: BOI participates in the RBI and CCIL FX-Retail platform, where individual and MSME customers can buy or sell US dollars against rupees at rates close to the interbank rate. It is worth using if you want a tighter rate on a specific conversion.

Every foreign exchange conversion in India attracts 18% GST. It is charged on a "value of supply" the RBI defines in slabs (in force since 1 July 2017), not on your full transfer amount, so it stays modest even on large sums.

The takeaway is simple. GST is a known, capped, and comparatively small cost. The exchange-rate margin is the variable you can actually influence.

Search "USD to INR" and you see the mid-market rate, the midpoint between global buy and sell prices. That is the fair reference rate, and no bank pays it out in full. The difference comes from three layers. The way bank foreign exchange pricing works explains why your payout trails that reference rate.

Spread: BOI applies a margin between the interbank rate and the rate it gives you, generally around 1% to 2.5% below mid-market on inward transfers, though it varies by day and currency. This is the foreign exchange markup, rarely shown as a line item.

Correspondent deductions: inward wires can pass through an intermediary bank that takes its own cut before the money reaches BOI, so the credited amount can be smaller than the sender's figure.

Market volatility: the rate moves through the day. Because your transfer settles at the prevailing rate, not the quoted one, timing changes the outcome.

The cleanest way to see the true price is to compare the applied rate against the live mid-market rate on the same day.

Say a client sends you USD 10,000 for a completed project, and the mid-market USD/INR rate that day is ₹89.40 (illustrative, as of July 2026).

• At the mid-market rate: 10,000 × 89.40 = ₹8,94,000
• At BOI's TT buying rate, roughly 1.45% lower at about ₹88.10: 10,000 × 88.10 = ₹8,81,000
• Difference from the rate margin alone: about ₹13,000, before the processing fee, GST, any FIRC fee, and the correspondent-bank deduction.

That ₹13,000 is not a fee you approved. It is the spread, and it repeats on every transfer.

Over a year of monthly foreign inward remittance, the same margin quietly compounds into a meaningful sum. You can cross-check the reference number any day against the live USD to INR mid-market rate.

There are three reliable ways to find the rate, in order of accuracy.

• BOI's forex card-rate sheet on its website, published on working days. It lists TTB, TTS, and travel rates per currency.
• Your account credit advice or FIRA, which records the exact rate applied to your specific transfer. This is the only rate that is truly yours.
• The branch or the FX-Retail platform, where you can see live USD/INR orders for eligible transactions.

A quoted morning rate is only a guide. The rate that lands is the one live at the moment of credit, which is why the FIRA figure and the morning quote rarely match to the paisa. Comparing BOI's sheet with another lender, such as sbm bank forex rates, shows how much the margin varies between banks. For compliance, the FIRA proves both the inward remittance and the rate applied.

Xflow is a cross-border payments platform built for Indian businesses and freelancers receiving money from abroad. The core difference is the reference rate.

BOI marks up a hidden interbank rate. Xflow converts at the live mid-market rate and charges a transparent, visible fee, so you can see exactly what conversion costs. Its published pricing, as of July 2026, is below.

Take the same USD 10,000 invoice on the Growth plan. The fee is 0.4%, about USD 40 (roughly ₹3,576 at ₹89.40), and the conversion happens at the mid-market rate rather than a marked-down one.

You keep close to the mid-market payout minus a fee you can see, instead of losing the spread you never agreed to. Xflow supports receiving in 25+ currencies from 140+ countries, converting at the mid-market rate rather than a bank spread, which can meaningfully lower FX costs on inward payments. Settlement is next business day (T+1), and each payment comes with an auto-issued eFIRA.

A few honest caveats belong here. If you already hold accounts, overdraft lines, and trade facilities with BOI, consolidating can matter more than a few paise on rate, and its FX-Retail route can give a tight rate on a one-off conversion.

For one-off or very small transfers, a flat fee can outweigh the rate saving. Run your own numbers on a typical invoice first, and read how to reduce international payment fees to see where the real leakage sits. For regular mid-to-large export receipts, the platform is used for cross-border payments for service exporters.

This is the fear that stops most exporters from switching, and it is worth addressing head-on. Receiving through a regulated platform does not break your regulatory trail.

Xflow holds final RBI Payment Aggregator - Cross Border (PA-CB) authorisation for both exports and imports (as of February 2026), works with AD-1 banks, and auto-issues an eFIRA for each payment.

Your purpose codes, GST refund workflow, and downstream reporting continue as before, and the bank FIRC route remains available. Compliance stays intact; the paperwork simply becomes less manual.

Bank of India's forex rates are set by a daily rate sheet, and the TT buying rate, not the advertised number, decides what lands in your account. FX-Retail can give a tighter rate on a specific conversion, and the Multi-Currency Prepaid Card covers travel spending.

The 18% GST is small and capped. The exchange-rate margin of roughly 1% to 2.5%, plus the processing fee and any correspondent-bank charge, is the real cost on inward transfers. If your sender banks in the US, it is worth checking how bank of america forex rates stack up on the same day.

Check the rate on your FIRA, compare it against the mid-market rate the same day, and if you receive export income regularly, run one invoice through a mid-market-rate platform to see the difference for yourself. Open Xflow's receiving accounts to test it on your next USD invoice.
