IDFC FIRST Bank does not use one exchange rate. It publishes a forex rate sheet each working day and revises it through the day as the market moves.
When money reaches you from abroad, IDFC FIRST 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 the bank 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 IDFC FIRST sets each rate, what a conversion really costs, how to read today's number, and how the maths compares.
Understanding IDFC FIRST Bank forex rates
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.
IDFC FIRST 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 the bank 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.
What do TT buying, TT selling and card rates mean?
TT stands for telegraphic transfer, the electronic movement of money between banks across borders. IDFC FIRST uses two TT rates and a separate card rate.
- TT buying rate: the rate at which the bank buys foreign currency from you and pays out rupees. This applies when you receive an inward remittance from a client abroad.
- TT selling rate: the rate at which the bank sells you foreign currency, used when you send money out.
- Card rate: used for the forex card and cash, and it carries a wider margin than the TT rates.
For anyone receiving export income, the TT buying 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).
| Rate type | Used when | Illustrative IDFC FIRST rate (INR/USD) |
|---|---|---|
| TT buying | You receive money from abroad | 87.90 |
| TT selling | You send money abroad | 89.90 |
| Card rate | Forex card or cash | 87.40 buy / 90.20 sell |
The mid-market rate that day is around ₹89.40, so every rate the bank quotes sits a margin away from it.
What are IDFC FIRST Bank's forex charges?
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.
| Service | IDFC FIRST charge (as of July 2026) |
|---|---|
| Inward remittance (credit to your account) | No IDFC FIRST fee to receive; TT buying rate margin applies; correspondent banks may deduct |
| GST on conversion | 18% on the converted gross INR amount |
| FIRC (if you request the certificate) | Nominal fee plus GST, on request |
| Outward remittance exchange fee | Around ₹300 per outward payment |
| Intermediary bank fee | ₹20 to ₹300, depending on the OUR, BEN, or SHA option |
Receiving money looks free because there is no headline fee. The margin baked into the TT buying rate does the quiet work instead.
IDFC FIRST markets its WOW and Ashva credit cards as "zero forex markup" products, which is a separate thing from the TT rate on an inward remittance. Verify current charges on the bank's own forex page before you rely on a figure.
How OUR, BEN and SHA affect what you receive
When a wire is sent, someone pays the correspondent-bank charges, and the option chosen decides who. This matters because it changes the amount that actually lands.
- OUR: the sender pays all charges, so you receive close to the full amount.
- BEN: the charges come out of the transfer, so you receive less after deductions.
- SHA: the sender and receiver each cover their own side.
If you are receiving export income, ask your client to send under OUR where possible, so intermediary fees do not eat into your payout.
How much GST applies to a forex 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.
| Conversion amount | Value of supply (taxable value) | GST at 18% |
|---|---|---|
| Up to ₹1 lakh | 1% of the amount (minimum ₹250) | ₹45 to ₹180 |
| ₹1 lakh to ₹10 lakh | ₹1,000 + 0.5% of amount above ₹1 lakh | ₹180 to ₹990 |
| Above ₹10 lakh | ₹5,500 + 0.1% of amount above ₹10 lakh (capped at ₹60,000) | ₹990 to ₹10,800 (maximum) |
The takeaway is simple. GST is a known, capped, and comparatively small cost. The exchange-rate margin is the variable you can actually influence.
Why are IDFC FIRST's forex rates different from the market rate?
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: IDFC FIRST applies a margin between the interbank rate and the rate it gives you, generally around 1% to 3% 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.
Correspondent deductions: inward wires can pass through an intermediary bank that takes its own cut before the money reaches IDFC FIRST, which is where the OUR, BEN, and SHA choice comes in.
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.
Rates also vary from one lender to the next, so it helps to compare a peer's sheet, such as tamilnad mercantile bank forex rates, on the same day.
What does the effective rate look like? A worked example
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 IDFC FIRST's TT buying rate, roughly 1.7% lower at about ₹87.90: 10,000 × 87.90 = ₹8,79,000
- Difference from the rate margin alone: about ₹15,000, before GST, any FIRC fee, and correspondent deductions.
That ₹15,000 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 usd to inr.
How can you check IDFC FIRST Bank forex rates today?
There are three reliable ways to find the rate, in order of accuracy.
- IDFC FIRST's forex rate sheet on its website, revised on working days. It lists TT and card 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 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.
How is Xflow different from IDFC FIRST Bank forex rates?
Xflow is a cross-border payments platform built for Indian businesses and freelancers receiving money from abroad. The core difference is the reference rate.
IDFC FIRST 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 IDFC FIRST's rate sheet says that morning.
| Plan | Fee | Best for |
|---|---|---|
| Starter | $12 flat up to $2,000; 0.6% above $2,000 | Invoices typically under $3,500 |
| Growth | $20 flat up to $5,000; 0.4% above $5,000 | Invoices of $2,000 to $10,000 |
| Scale | Custom pricing | Invoices of $10,000+ |
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 keeps far more of each payment than a bank spread would, 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 IDFC FIRST, 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 used for cross-border payments for service exporters.
Does moving off your bank break compliance?
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.
The bottom line
IDFC FIRST Bank'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. Ask senders to use the OUR option so correspondent fees do not shrink your payout.
The 18% GST is small and capped. The exchange-rate margin of roughly 1% to 3% 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.
Start saving more on every international transfer.
Frequently asked questions
The bank quotes a TT buying rate for money you receive, a TT selling rate for money you send, and a wider card rate for its forex card and cash. Each sits a margin below or above the mid-market rate, and the margin is the main cost.
There is no IDFC FIRST fee to credit an inward remittance, but 18% GST applies on the converted amount, correspondent banks may deduct their own charges, and a FIRC costs a nominal fee plus GST if you request one.
It is the rate at which the bank converts incoming foreign currency into rupees. It is lower than the mid-market rate, and the difference is the bank's margin. This is the rate that applies when you receive money.
They decide who pays the correspondent-bank charges. OUR means the sender pays, so you receive close to the full amount. BEN means the fees are deducted from your payout. SHA splits them.
Use IDFC FIRST's forex rate sheet on its website, revised on working days. The exact rate applied to your transfer appears on your credit advice or FIRA.
Google shows the mid-market rate. The bank adds a spread of roughly 1% to 3%, so the rate you receive is below it. The applied rate on your FIRA reflects that margin.
Savings depend on your volume and the rate margin. On regular mid-to-large receipts, converting at the mid-market rate with a visible fee can cut FX costs compared with a bank spread.
