This article breaks down how these two rates work, what each is for, how they are formed, and which one to look at in a given situation.

What the NBT official rate is

The official rate is the rate published daily by the National Bank of Tajikistan. It is used for:

• Accounting in Tajikistan.
• Calculating customs payments.
• Converting currency-denominated obligations into somoni (wages, contracts, taxes).
• Government statistics and reporting.

This rate is calculated on the basis of the interbank market — the rate at which banks buy and sell currency from each other. The NBT sets it as a benchmark for the whole economy and publishes it daily.

Important to understand: you will not exchange cash at the official rate. It is a "paper" rate, not a "counter" rate. When a bank serves an individual, it builds its own margin into the rate — otherwise the whole operation would be a loss for the bank.

What the bank rate is

The bank rate is the number on the board you actually exchange money at. It is built up from:

• A base — close to the NBT official rate (or to the interbank rate the NBT uses to set its own).
• A bank margin — the price of organising the exchange, premises rent, cashier wages, insurance, and operational profit.

The margin splits two ways: the buy rate is below the base (the bank buys cheaper), the sell rate is above the base (the bank sells dearer). The gap between them is the spread. There is a full breakdown of the spread — in the article on the best rate.

Widget: bank rates right now

The widget shows rates from specific banks — the very "bank" rates at which real cash currency exchange happens. Compare with the NBT official rate and you will see how and by how much they diverge.

Why the official rate sits below the bank's buy rate

"It is strange that the NBT rate in the news is 10.67 but the bank will only buy my dollar at 10.80?" — the logic is actually this:

• The NBT rate is a weighted average for the specific day. There is one of it.
• The bank has two rates: buy and sell. The spread sits between them.
• The sell rate at the bank is always above the official NBT rate.
• The buy rate at the bank is always below the sell rate, and can be slightly above or slightly below the official one — it depends on the specific bank's spread.

So if the NBT publishes 10.67 somoni per dollar, the typical picture at the bank is: buy 10.55–10.80, sell 10.85–11.15. Sometimes buy is slightly above the official rate, sometimes slightly below — depending on how the bank set the spread.

Worked example

Suppose today's NBT official rate is 10.67 somoni per dollar. Bank A runs a 2% spread, bank B a 3.5% spread, bank C a 4.5% spread.

If you have dollars and need somoni (selling), the best bank is A; the gap versus bank C on $1,000 is about 140 somoni.

If you need dollars (buying), the best bank is A; the gap on $1,000 is about 130 somoni.

If you plan to swing back and forth — bank A saves you on both sides.

Which rate to look at in which situation

Why the official rate matters even for an individual

A few situations where the official rate is useful not just to accountants:

Customs. On entry with a sum above $3,000 equivalent, a declaration is mandatory. The equivalent is calculated at the NBT rate on the declaration date. If you have roubles, you need to check: today, are 300,000 roubles below or above the $3,000 equivalent at the NBT rate?

Contracts and agreements. If you rent accommodation in Dushanbe pegged to the dollar, the agreement often says "payment in somoni at the NBT rate on the payment date". The official rate is then a working tool.

Salary in dollars paid out in somoni. If the employer pays in somoni at the equivalent, the calculation usually runs at the NBT rate on the payment day.

Taxes. Income declaration in foreign currency — recalculated at the NBT rate on the receipt date.

Why the bank rate is not a "scam"

Sometimes there is the illusion that "the NBT publishes a fair rate and the bank profits from the gap". That is not the case.

The bank's margin is not "extra money" — it pays for the work:

• Premises rent and equipment.
• Staff salaries.
• The cost of storing cash currency.
• Insurance against not receiving currency or accepting counterfeits.
• Reserves against rate swings.
• Regulatory costs.

If the bank exchanged exactly at the NBT rate it would quickly go into the red. A reasonable margin is the norm of how foreign-currency markets work in every country.

The spread in Tajikistan is not the worst in the world. At European airports the spread is often 6–10%, at tourist exchange offices — up to 15%. Against that, 2–3% at Dushanbe banks is a humane number.

How to find the NBT rate

The rate is published daily on the official site of the National Bank of Tajikistan (nbt.tj). It is also usually shown on:

• Tajik information portals.
• Major bank websites (as a reference).
• Financial apps with rates.

On themoney.tj the official NBT rate is also shown as a benchmark — alongside bank rates for easy comparison.

Rate history: where to see trends

If you want to understand where the dollar (or rouble, or euro) is heading against the somoni, look at the NBT official rate history. That is the base. From the NBT history you can project trends (within reason).

The rates of specific banks in the moment are "the current offer". History on them is less revealing because they move with the NBT plus their own margin.

Bottom line

Before an exchange, check the bank rate via the widget. That is the number at which you actually receive somoni (or dollars/roubles).

For a market view, look at the NBT official rate. It gives a "fair middle" — a reference point.

For documents and official settlements — the NBT rate only. No "bank rates" should ever appear in a declaration or contract.

Do not be startled by the gap. A 2–4% spread is the norm for cash currency operations in most countries.

Frequently asked questions

How does the NBT rate differ from the bank rate?

The NBT rate is the official, weighted-average rate for accounting, documents and taxes. The bank rate is the real cash exchange, including the bank's margin. The bank's sell rate is usually above the NBT, the buy rate close to it or slightly below.

Can I exchange currency at the official NBT rate?

No. Cash exchange does not happen at the official NBT rate. That is an accounting rate. Real exchange always carries the bank's margin.

Why do different banks have different rates?

Each bank sets its own margin on top of the official rate. The larger the bank and the more active it is with cash currency, the narrower the margin. Smaller banks offset modest turnover with a wider quote.

Which rate to use for a customs declaration?

The NBT rate on the day of the declaration. The $3,000 equivalent (the mandatory declaration threshold) is calculated at it.

Where to see the NBT rate?

On the National Bank of Tajikistan website (nbt.tj). The rate is also published on financial portals and in the widget on themoney.tj — for comparison with bank rates.

What is the interbank rate?

The rate at which banks buy and sell currency from each other. The NBT sets the official rate based on this market. For individual clients, the interbank rate is a "fair middle" benchmark.

Can the bank rate be below the official NBT rate?

The buy rate at the bank can be slightly above or slightly below the official rate — it depends on the spread. The sell rate at the bank is always above the official one — otherwise there is no point for the bank to operate.

Is the gap between the NBT and the bank rate considered a commission?

Not formally. There is usually no separate exchange commission at the bank — it is built into the spread between buy and sell. So in fact the gap between the bank and the official rate is the cost of the operation for the client.

How often does the NBT rate change?

Daily. A new rate is published on every working day. On weekends the previous business day's rate applies.
