The evening news says the dollar is at one rate. The money changer down the road quotes another. Your cousin's remittance arrived at a third. If you've ever wondered why Pakistan seems to have several different dollar prices at once, you're not imagining it — there are two official ones, and which you get depends entirely on how your dollars move. Here's the difference between the interbank and open market dollar rates, and which one applies to you.
What is the interbank rate?
The interbank rate is the wholesale price of the dollar: the rate at which banks buy and sell foreign currency among themselves in large volumes. The State Bank of Pakistan (SBP) collects these trades and publishes a daily weighted-average interbank rate — this is the number quoted on TV tickers and business pages as "the dollar rate".
Think of it as the factory-gate price. It reflects big flows — export receipts, import payments, SBP intervention, foreign investment — and it moves during trading hours as banks adjust their positions. Ordinary customers almost never transact at the interbank rate; it is the benchmark everything else is priced off.
What is the open market rate?
The open market rate is the retail price: what licensed exchange companies and forex dealers charge walk-in customers buying or selling dollar notes. It is the rate on the board at the money changer's shop, and it is almost always slightly higher than the interbank rate when you're buying dollars — the difference is the dealer's margin, covering their costs, risk and profit.
Exchange companies in Pakistan are licensed by the SBP and report their dealings, but their retail quotes respond to street-level supply and demand: holiday travel seasons, Hajj/Umrah demand, or panic buying during a currency scare can push the open market rate noticeably above interbank for days at a time.
Interbank vs open market: side by side
| Interbank rate | Open market rate | |
|---|---|---|
| What it is | Wholesale rate between banks | Retail rate at exchange companies |
| Published by | State Bank of Pakistan (daily average) | Each dealer; Exchange Companies Association quotes |
| Who uses it | Banks, importers/exporters, SBP | Travellers, small buyers/sellers of notes |
| Typical spread | — (the baseline) | Usually Rs. 1–3 above interbank for buyers |
| Where you see it | News tickers, SBP website | Money changer boards |
Why the two rates differ — and when the gap widens
A small gap is normal and healthy: it is simply the retailer's margin, the same reason a shop charges more than the wholesale mandi. The gap becomes a story when it widens sharply, which tends to happen when:
- Dollar demand spikes — travel seasons, import surges or panic buying drain the retail market faster than dealers can restock.
- Speculation takes hold — when people expect the rupee to fall, they buy dollars as a hedge, and dealers price in the risk.
- Controls tighten — SBP crackdowns on unlicensed trading or limits on foreign-currency movement can squeeze the legal retail supply, pushing its price up.
- Confidence wobbles — during balance-of-payments scares, the interbank rate itself may be held steady by SBP intervention while the open market reflects what buyers will actually pay — the gap becomes a stress gauge economists watch.
A persistently wide gap is a signal, not just a price: it tells you the official rate and the street rate disagree about where the rupee should be.
How the gap behaved in past stress episodes
The interbank–open market spread has a history as a crisis barometer. During Pakistan's 2022–23 balance-of-payments stress, the open market premium over interbank widened to several rupees at its worst as importers and savers scrambled for dollars while official channels tightened. Each episode followed the same script: SBP intervention steadied the interbank print, retail demand kept climbing, and the gap became the market's honest vote on where the rupee was heading.
The pattern repeats because the two rates answer to different masters. Interbank reflects what banks — operating under SBP oversight — will trade at. Open market reflects what thousands of individuals will actually pay, right now, in cash. When those disagree for more than a few days, the eventual adjustment usually comes to the interbank rate, not the street. Watching the spread is therefore one of the simplest ways a non-economist can read currency stress in real time.

Rates move daily, so let's use round illustrative figures (as of 2026) to show the mechanics. Suppose the interbank rate is Rs. 280 per dollar and the open market selling rate is Rs. 281.50:
