What drives the hryvnia exchange rate and how the NBU sets the official rate

Three rates you see every day

When people say «the dollar rate», they usually mean one of three numbers. They are linked, but each is set differently and they can diverge noticeably.

The official rate is a snapshot of the interbank market from the previous day. The retail rate is the price at which a bank will sell you a dollar or buy one from you. The difference between them is what the bank or exchange office earns, and on turbulent days it is also a charge for risk.

How the NBU calculates the official rate

The National Bank publishes its methodology openly, and it is pure arithmetic. The official hryvnia-dollar rate comes from real deals concluded that same day.

1. 1Deals are collectedDollar purchase and sale deals between banks, and between banks and the NBU, concluded on the calculation day. Only deals of USD 100,000 to 5 million count.
2. 2Outliers are removedDeals at a rate too far from the rest are dropped in two stages, so one odd trade can't shift the result.
3. 3A weighted average is takenEach deal affects the result in proportion to its size: a large deal weighs more than a small one.
4. 4The rate is fixed and publishedThe calculation uses data as of 15:00 Kyiv time, and the rate is published by 15:30.
5. 5The rate takes effectA rate set today applies from the next working day. Monday's rate is set on Friday.

Separately, the NBU calculates a reference value of the rate from deals up to 12:00. Companies that settle with counterparties during the day use it as a benchmark before the official rate appears.

Where the euro, zloty and other rates come from

There is practically no separate market for hryvnia against the zloty or pound in Ukraine: most interbank deals are in dollars, and the euro's share there remains small. So the NBU calculates official rates for other currencies via the dollar, using global quotes of those currencies against the dollar (including Bloomberg indicators as of 15:00), rates of the issuing central banks and trading system data.

The NBU sets rates for the currencies of main trading partners and EU countries daily, and for less used ones monthly, on the last working day of the month.

Fixed, floating and managed flexibility

How much the rate can move depends on the exchange rate regime, the rules by which the central bank intervenes in the market. Since independence Ukraine has been through all the main options, and each left its mark on people's wallets.

Over these years the dollar rose 5.7-fold against the hryvnia. But the more important lesson is how it happened. When the rate was held artificially for a long time (until 2014), the built-up pressure came out as a sharp collapse. When the rate moves gradually, people and businesses find it easier to plan.

That's how the NBU explained abandoning the fix in 2023: holding the rate for a long time creates a false sense of stability and accumulates imbalances, and the longer a fix lasts, the harder it is to exit. At the same time, letting the rate float freely during the war is impossible: the market has a structural shortage of foreign currency, and without support the hryvnia would keep weakening.

What «managed flexibility» means

• The rate moves both ways. The hryvnia can weaken or strengthen depending on supply and demand.
• The NBU covers the currency shortage. It sells as much currency on the interbank market as the market lacks, smoothing swings.
• The NBU doesn't allow sharp jumps. Neither a significant weakening nor a substantial strengthening of the hryvnia in a short time.
• There's no target rate. The NBU doesn't announce what rate it considers right and doesn't promise to hold any level.

What drives the rate: supply and demand for currency

The exchange rate is the price of a dollar in hryvnias, and it follows the same rule as any market price. If more people want to buy dollars than sell them, the dollar gets more expensive. If supply exceeds demand, the hryvnia strengthens. Every factor mentioned in the news ultimately affects one of the two sides of this balance.

The trade deficit: the main source of pressure

During the war Ukraine buys far more goods abroad than it sells. According to the State Statistics Service, in January-September 2025 goods exports were USD 29.6 billion and imports USD 60.2 billion: for every dollar earned from exports there were about two dollars of imports. In 2026, according to the State Customs Service, imports over nine months rose by another quarter while exports stayed close to last year's level. Port blockades and strikes on enterprises cut exports of agricultural products and metals, while demand for fuel, energy equipment and machinery grew.

The market couldn't cover this gap on its own: with a free rate the hryvnia would weaken until imports became too expensive. International aid covers the difference.

International aid and the NBU as intermediary

Partners' money arrives in the government's currency accounts at the NBU. The government sells the currency to the National Bank, receives hryvnias and spends them in the country. The NBU in turn sells those dollars on the interbank market to those who need currency for imports or savings. That's how partners' aid indirectly becomes currency supply on the market.

Interventions grow with each year of the war: in 2025 the NBU sold USD 36.1 billion, and in January-October 2026 alone USD 44.28 billion, the most in ten years. So the key question for the rate in the coming years is whether aid arrives on time and in full. In its October forecast the NBU directly links FX market stability to meeting commitments under programmes with international partners.

The key policy rate and inflation

A second group of factors decides how worthwhile it is to keep savings in hryvnias. If hryvnia deposits and government bonds pay noticeably more than currency ones, and that return beats inflation, some people and companies are in no hurry to buy dollars. Demand for currency falls.

The main tool here is the NBU key policy rate. Deposit rates and government bond yields depend on it. In summer and autumn 2026 the National Bank raised the key rate from 15% to 16.5%, and in its Inflation Report named one reason directly: to limit pressure on the FX market and keep hryvnia savings attractive. The mechanism is described in detail in the article on the NBU key policy rate.

Inflation affects the rate over the long run. If prices in Ukraine rise faster than in the US or the euro area, the hryvnia gradually loses purchasing power against the dollar and euro, and the rate reflects this over time. That's why countries with high inflation almost always have weaker currencies. In September 2026 inflation in Ukraine was 10.0%. Compare: over the year the dollar rose 8.3%, meaning the hryvnia lost value against the dollar more slowly than against goods in shops. Why this happens and what it means for savings is explained in the article on inflation.

Expectations and people's behaviour

Expectations also move the rate: what people think the rate will be tomorrow. If many decide the dollar will soon rise and go to buy it, demand grows and the rate really does change. Expectations can be self-fulfilling, which is why the NBU watches them closely and explains its decisions.

• Scale. According to the NBU, in October 2026 households bought almost USD 1 billion more cash currency than they sold. For comparison, that's a sixth of the NBU's monthly interventions.
• Start of the month. The NBU notes that people buy currency more actively at the start of the month: salaries arrive and the monthly limit on non-cash currency purchases (UAH 200,000 per month at one bank) resets.
• News. Reports of delayed aid, strikes on energy or port blockades trigger buying waves. News of tranches arriving calms the market.
• Business. Companies expecting the hryvnia to weaken delay selling their earnings and buy currency in advance. This adds to pressure in turbulent periods.

That's why international reserves matter even when the NBU isn't actively spending them. A large currency buffer shows the market that the National Bank can cover a shortage, and reduces the urge to buy dollars «just in case».

Why the bank rate differs from the official one

A person can't buy a dollar at the official rate: the bank sells currency for more and buys it for less. The difference between the selling and buying rate covers the bank's costs and the risk that the rate changes while the currency sits on its balance sheet.

• Cash costs more than card. A bank has to import cash currency from abroad, transport, store and collect it. So the cash rate is usually worse for the buyer than the rate in the app.
• Weekends cost more. The interbank market is closed at weekends, and banks build a bigger buffer into the rate in case things change by Monday.
• On turbulent days the gap widens. In early November 2026 the NBU noticed that banks' selling rates had moved further from the official rate than usual. It consulted banks and offered to swap their non-cash currency for cash. Banks took only part of the offer, and the gap began to narrow: the NBU stressed there were no economic grounds for it.

How to exchange currency with the smallest losses and what to look for in bank rates is described in detail in the article on currency exchange.

How the rate affects prices, salaries and debts

Even if you don't own a single dollar, the rate reaches your wallet through prices. Fuel, home appliances, smartphones, medicines, cars and much of the raw material for Ukrainian producers are bought in foreign currency. When the hryvnia weakens, an importer pays more hryvnias for the same delivery and sooner or later passes it on in the price.

• Fastest to react are prices of fuel, electronics, cars and package holidays: they are tied directly to currency.
• With a delay come food and services where only part of the costs is imported: packaging, fertiliser, equipment, logistics.
• Slowest to change are hryvnia salaries and pensions. So a sharp weakening of the hryvnia hits people with hryvnia incomes first.
• Foreign currency loans after 2014 became a textbook case: borrowers with hryvnia incomes suddenly had to pay twice as much. A currency loan without currency income is a risk best avoided.

There's another side too. Exporters get more hryvnias for their products and can pay higher salaries. Ukrainians who receive money from abroad or work for foreign clients gain from a weaker hryvnia. That's why the NBU aims for smoothness: the economy can absorb a gradual weakening, while a sharp jump both drives up inflation and wrecks plans.

Where to check the official rate

The primary source is the National Bank's website, official exchange rates section: the rate for the next working day is published there after 15:30, with an archive for any date. Aggregators and banking apps show the same figures but may update them with a delay. For documents, tax reporting and converting foreign currency income, the NBU official rate on the transaction date is what counts.

Can the rate be predicted

In short: not with accuracy that's useful to you. The NBU doesn't publish an exchange rate forecast, and for good reason: the market would take a central bank forecast as a promise. Bank and investment company analysts give ranges for a few months ahead, but these are revised regularly, because the rate depends on events nobody knows in advance, from the timing of aid to the situation at the front and in energy.

What can be said with confidence:

• As long as the large trade deficit persists, the hryvnia will stay under pressure, and its stability will depend on international aid.
• The managed flexibility regime makes sharp jumps less likely, but doesn't rule out gradual weakening of the hryvnia.
• If inflation in Ukraine is higher than in the US and the euro area, over the long run the hryvnia weakens against the dollar and euro.
• Short-term swings (a week to a month) have little to do with the economy and are almost impossible to predict.

What the rate means for your money

The practical conclusion from all this: manage your savings based on your goals and spending, without trying to guess the rate.

Keep money in the currency of your future spending

If you plan to live in Ukraine and spend hryvnias, most of your emergency fund and short-term goals logically sit in hryvnias. If a trip, studies or a purchase abroad lies ahead, it makes sense to keep part of the savings for that goal in currency. Long-term savings are often split between hryvnias and currency so that no rate scenario becomes a disaster for you.

Compare including interest rates

A hryvnia deposit pays more than a currency one, and that difference works as a buffer against hryvnia weakening. Let's work out the rate a year from now at which the two options are equal.

Nobody knows how likely each outcome is, so it's wiser to split money between currencies than to bet everything on one scenario. A calculation with different amounts and terms, and the risks of each option, is in the article hryvnia or dollar deposit.

Buy currency in instalments

If you save in currency, buy it regularly in small amounts, for example from every salary. Then the average purchase price smooths out fluctuations, and you don't have to decide whether today is a good day. Large one-off purchases on a wave of panic most often land on the highest rate.
