More favorable dollar exchange rate: which days are best for Ukrainians to buy currency.

During currency exchange, many Ukrainians do not take advantage of the opportunity to 'catch' a more favorable dollar or euro exchange rate by simply buying currency at the right moment. However, indications of price fluctuations help people understand when it is best to exchange foreign bills. The News.LIVE website shared information on which days of the week it is more advantageous for Ukrainians to buy dollars.

When is it best to exchange currency

The currency market has its own rules and restrictions. For example, weekends when official rates remain unchanged, and fluctuations occur only in the cash market. The system closes trading on Friday evening and opens it again only on Monday morning.

By tracking the dollar exchange rate, Ukrainians can notice a certain regularity. For visualization, a chart on the Minfin portal can be used. The cash exchange rate may fluctuate, but changes do not happen randomly. This is well seen on the monthly chart.

Peaks in the exchange rate are observed on days when the currency is more expensive. For example, in July 2025, the price of the dollar increased on such days:

• July 8 (Tuesday);
• July 17 (Thursday);
• July 24 (Thursday);
• July 30 (Wednesday).

Meanwhile, the exchange rate decreased on July 11, 18, and 25, especially on Fridays. Their analysis shows that the peak dollar value occurs on Wednesdays, but on Fridays, the rates usually decrease.

Thus, it is more profitable for Ukrainians to buy dollars at the end of the week and sell them from Tuesday to Thursday. Although the fluctuations in the exchange rate are small (up to 10 kopecks), for those exchanging significant sums, this can be important.

What will happen to the dollar exchange rate in August

Economic expert Danilo Monin commented to the News.LIVE newspaper about expected changes in the dollar exchange rate in the near future. He believes that the figures will depend on investors' reactions to the US Federal Reserve's decisions regarding interest rates.

Since December 2024, the Federal Reserve has kept the rate at 4.25-4.5%, which could lead to stability in the dollar exchange rate in August. However, the strengthening of the euro may have a significant impact on this rate.

After the agreement between Trump and the EU on tariffs on imports and agreements regarding the purchase of energy goods from the USA, the dollar rate fell from 1.18 to 1.14 USD/EUR. If this continues into August, we can expect that the dollar will rise to 42-42.50 UAH, "said Danilo Monin.

In the case of the European currency strengthening, the dollar rate will remain below 42 UAH. Otherwise, Ukrainians might see another increase in the dollar rate above the psychological barrier.

What else is useful for Ukrainians to know

The Iranian authorities plan to conduct a redenomination of the national currency rial, reducing the number of zeros on banknotes. This will help simplify financial transactions and save on the production of cash.

The maximum amount of cash that can be exported from Ukraine without additional declaration was also considered. Now, when exporting an amount equivalent to 10,000 euros (in any currency in the world), it is not necessary to inform customs officials about this.

The news presented in a lively style explains when it is profitable for Ukrainians to buy and sell dollars and also predicts changes in currency exchange rates. In particular, information about the most advantageous days for currency exchange and the expected changes in the dollar exchange rate in August is provided. Useful facts about the redenomination of the Iranian rial and the export of cash from Ukraine without declaration are also mentioned.
