Indian Overseas Bank Forex Rates Explained | How to Save on Transfers

Indian Overseas Bank (IOB) does not use one exchange rate. It publishes a daily foreign-exchange card-rate sheet, dated, and moves it as the market moves.

When money reaches you from abroad, IOB 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 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 IOB 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 IOB sets each rate, what a conversion really costs, how to read today's number, 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.

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

Other public-sector lenders publish the same style of sheet: see Central Bank of Indian Forex Rates for how a comparable bank lays out its TT and card rates.

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

• TT buying rate: the rate applied when a foreign inward remittance is credited to your account. This is the rate that matters when you receive export income.
• TT selling rate: the rate at which IOB sells you foreign currency, used when you send money out.
• Bill buying and selling rates: used for foreign cheques, drafts, and trade documents, slightly wider than the TT rates.
• Card rate: used for the forex card and cash, and it carries the widest margin.

For anyone receiving export income, the TT buying rate is the number to watch. 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 IOB 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 looks close to free because the visible charge is small. The margin baked into the TT buying rate does the quiet work instead. The forex card also carries a monthly inactivity fee of about USD 1.50, EUR 1, or GBP 1 after 12 months, so close a dormant card.

IOB revised its service charges from 1 April 2026, so verify the current numbers on IOB's own service-charges page before you rely on a figure.

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.

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

Cards and cash cost more: the forex card and cash carry a wider margin than TT rates, and the bill rate for cheques and documents sits slightly wider than the TT rate too.

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.

Private-sector lender IDBI Bank forex rates apply a similar spread structure, just with its own day-to-day margin.

Among public-sector peers, bank of india forex rates follow the same margin-plus-fees pattern, only with different day-to-day numbers.

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 IOB'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 GST and any FIRC fee.

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 using the USD to INR rate.

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

• IOB's daily FX card-rate sheet on its website, dated and revised on working days. It lists TT, bill, and card rates per currency, and can be downloaded as a PDF.
• 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 relationship manager, useful if you are negotiating on higher volumes.

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. For compliance, the FIRA is the document that proves both the inward remittance and the rate applied. Every Indian bank runs the same dated rate-sheet system with its own margins, so if you want to see how indian bank forex rates compare across major lenders, that roundup is a useful next stop before deciding whether to move volume off IOB.

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

IOB 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.

Opening dedicated receiving accounts in USD, GBP, EUR and other major currencies means every inward payment lands against a rate you already agreed to, not whatever IOB's rate sheet says that morning.

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. On costs like these, businesses moving off a bank's marked-up rate typically keep a meaningfully larger share of each invoice, and the gap widens as volumes rise. 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 IOB, consolidating can matter more than a few paise on rate.

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 built for cross-border payments for service exporters.

Clients on the other side of the corridor can trim their own costs too; our guide on how to save money while sending from usa to india covers where the USD to INR leakage sits before the funds even reach you.

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.

Indian Overseas Bank's forex rates are set by a daily, dated rate sheet, and the TT buying rate, not the advertised number, decides what lands in your account. Watch the TT rate for wires and the bill rate for cheques and documents.

The 18% GST is small and capped. The exchange-rate margin, often around 1% to 2.5%, is the real cost on inward transfers, and it repeats every time.

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.

If you also bank with Indus Ind Bank forex rates, the same margin-plus-fees mechanics apply, just with different day-to-day numbers.
