The interbank rate is the wholesale price banks pay when they trade currency with each other. The open market rate is what money changers quote for physical cash. The open market rate is usually higher for buyers because banknotes cost money to handle and insure, so you pay a spread on top of the wholesale price.
If the rate on the news never matches the money changer’s board, this is the reason. Two markets, two prices. Before you exchange anything, run your amount through our free currency converter to see what it is worth at the current rate.
The interbank rate vs open market rate question spikes every time the rupee moves. It matters most for remittance families and travelers, so here is which rate actually applies to your money.
What the interbank rate actually means
Banks constantly move currency between themselves. A bank in Karachi settling an import bill, a treasury desk in Dubai hedging a loan. All of this happens in the interbank foreign exchange market, the wholesale tier of the global foreign exchange market, where trades are measured in millions, not the $300 in your pocket.
So the interbank exchange rate meaning is simple: it is the price at which banks buy and sell currency among themselves. Volumes are enormous and competition is fierce, so the gap between buying and selling prices is razor thin. This is the rate you see on business news tickers and in official State Bank of Pakistan data.
You cannot trade at this rate directly. It is wholesale, the same way a supermarket pays wholesale for milk and charges you retail.
What the open market rate is
The open market is the retail cash market: licensed exchange companies and money changers buying and selling physical banknotes over the counter. When people quote the open market dollar rate in Pakistan, they mean the number on the board at an exchange company branch, the one your uncle checks before selling the dollars he brought back from Riyadh.
Every changer posts two numbers. A buying rate (what they pay for your dollars) and a selling rate (what you pay for theirs). The difference is their margin, and it is where the whole money changer rate vs bank rate puzzle starts: the changer deals in paper, the bank deals in electronic balances. Paper is expensive.
Why the open market rate runs higher
Physical cash has real carrying costs. Notes must be counted, checked for fakes, stored in a safe, insured, and shipped to wherever demand is. An exchange company also carries inventory risk: hold dollars overnight and a falling rate eats the profit.
Then there is scarcity. When the rupee is under pressure, people hoard cash dollars and supply dries up, so the premium widens. Pakistan saw this in 2023, when the gap grew large enough that the IMF program required it to stay within 1.25 percent of the interbank rate. When a spread becomes an IMF condition, you know it matters.
A healthy exchange rate spread is small, often under 1 percent. Cash quotes running 3 or 4 percent above interbank mean something is stressed, usually the supply of banknotes. For what moves both rates in the first place, see our guide to how exchange rates work.
A worked example: what the spread costs you
Say you need $500 in cash for a trip, and today’s rates look like this (round numbers for easy math). Interbank: 278.00 rupees per dollar. Open market selling rate: 281.50.
Step 1: find the spread. 281.50 minus 278.00 is 3.50 rupees per dollar.
Step 2: turn it into a percentage. 3.50 divided by 278.00 is about 0.0126, or 1.26 percent.
Step 3: apply it to your amount. You pay 500 times 281.50, which is 140,750 rupees. At the interbank rate the same dollars would cost 139,000. The spread costs you 1,750 rupees.
That 1,750 is not a scam. It is the price of getting physical banknotes on demand. But knowing the number changes how you shop: a changer quoting 280.90 instead of 281.50 saves you 300 rupees on this one transaction, and asking costs nothing.
Which rate applies to your money
This is where most of the confusion lives, so here is the honest map.
| Situation | Rate you actually get |
|---|---|
| Remittance through a bank | Interbank-based rate, minus a small bank margin |
| Remittance paid out by an exchange company | Close to interbank, set by the transfer service |
| Cash at a money changer | Open market rate |
| International card payment | Card network rate plus your bank’s foreign transaction fee |
| Online transfer apps (Wise, Remitly) | Near interbank, plus a stated fee |
| Airport exchange counter | Open market rate with a wider spread |
The remittance row surprises people. Money sent home through official channels converts at interbank-linked rates, normally the better deal, which is why governments keep nudging remitters toward banks. If you are asking which rate applies to remittances from abroad, the answer for anything through a bank is: the good one.
Card payments are their own animal. Visa and Mastercard convert at their own wholesale rates, close to interbank, and your bank then stacks a foreign transaction fee on top. That fee is also why your card statement never matches what Google showed you; we broke that down in why your exchange rate differs from Google.
How to check both rates before you exchange
Search USD to PKR interbank vs open market and you will mostly find live rate tables. Useful for the number, useless for context. The interbank reference rate is published every business day by the State Bank of Pakistan, and open market rates are posted by exchange companies (honestly, the boards outside the shops update faster than half the websites). Compare the two before any big exchange and you will know at a glance whether a cash quote is fair.
Next time the dollar moves and everyone in the family group chat quotes a different rate, you will know why the numbers disagree. Run your amount through the free currency converter first, then compare that figure against any cash quote before you commit. The spread only hurts when you do not see it coming.
Frequently asked questions
What is the difference between the interbank rate and the open market rate?
The interbank rate is the wholesale rate at which banks trade currency with each other, while the open market rate is the retail rate money changers quote for physical cash. The interbank rate applies to bank transfers and large transactions. The open market rate applies to cash bought or sold over the counter.
Why is the open market dollar rate higher than the interbank rate?
The open market dollar rate is higher because physical cash carries extra costs that electronic bank balances do not. Money changers pay for security, storage, insurance, and transport, and they hold inventory that can lose value overnight. When cash dollars are scarce, demand pushes the premium even wider.
Which rate do banks use for remittances sent from abroad?
Remittances sent through banking channels are converted at a rate based on the interbank rate, usually with a small margin taken by the receiving bank. In Pakistan, money received through banks or licensed exchange companies is paid out near the interbank rate, which is generally better than selling cash at a changer.
Which rate do I get when exchanging cash at a money changer?
Cash exchanged at a money changer is priced at the open market rate, not the interbank rate. Every changer posts two numbers: a buying rate and a selling rate, and the gap between them is their profit. Compare quotes from two or three shops, because rates vary street to street.
Who sets the interbank rate in Pakistan?
No single authority sets the interbank rate in Pakistan; it is determined by supply and demand among commercial banks trading with each other. The State Bank of Pakistan monitors the market and can intervene, but since 2019 Pakistan has followed a market-based exchange rate system rather than a fixed peg.
Which rate applies to international card payments?
International card payments use neither the interbank nor the open market rate; they are converted at the card network’s own wholesale rate, which sits close to the interbank level. Your bank then adds a foreign transaction fee, typically 1 to 3.5 percent, so the final cost usually lands above interbank.
