Exchange rate basics
Do Exchange Rates Change on Weekends?
Saturday morning, a trip on Monday, and a simple question: if I change money today, do I get a worse rate? The market rate itself hardly moves on a weekend, because the market that sets it is closed. What can change is the price a bank, an app or an exchange office quotes you, and that difference is worth knowing before you convert.
The market closes, so the rate freezes
There is no single currency exchange. Rates are set by banks and large institutions trading with each other around the clock, five days a week. The trading week starts on Monday morning in New Zealand and Australia, which is Sunday evening in UTC, and ends when New York closes on Friday at 5 pm local time. Between those two moments almost nothing trades.
That is why a rate chart goes flat on Saturday and Sunday, and why the rate you see in a converter on Saturday is essentially Friday's closing rate. Official reference rates follow the same calendar: the European Central Bank publishes its euro reference rates only on working days, so a Saturday has no rate of its own. For an invoice or a tax return dated on a weekend, the last published rate before it is commonly used, but the rule your tax authority or employer sets comes first.
What can still change: the price you are quoted
Anyone who sells you currency on a Saturday takes a risk. They hand over euros or dollars at Friday's rate, but they cannot cover that position until the market reopens. If big news breaks over the weekend, Monday's rate can open well away from Friday's close. Many providers protect themselves by charging more.
How much more depends on who you deal with. Several money apps that use the market rate during the week add a fee to weekend exchanges and say so on their fee pages. As of November 2026, Revolut adds 1% on its Standard plan and 0.5% on Plus. Curve says it adds 0.5% for the euro, the dollar and the pound and 1.5 to 2% for less common currencies. Wise says it uses the last rate from Friday instead. Banks and exchange offices rarely publish a separate weekend fee, but they can widen the spread, the gap between the price at which they buy a currency and the price at which they sell it, until the market reopens.
Some prices do not depend on the day at all. An airport exchange desk is expensive on Tuesday and on Sunday alike. The useful comparison is always the same: the quote you are offered against the mid-market rate.
Card payments on a Saturday
Card networks do not add a weekend surcharge. Visa does not load new rates on Saturdays and Sundays and uses the rate set before the weekend. Mastercard publishes one rate a day and applies the rate in effect when the payment is authorised, which is usually the moment you pay. Either way, a weekend card payment is usually converted at a rate that reflects the market's Friday close.
Where a weekend payment does cost more, the extra comes from your own bank or app, so its fee page is the place to check. What still costs real money on any day of the week is accepting a conversion into your home currency at the terminal: choose the local currency every time.

Is waiting for Monday a good idea?
Waiting avoids the weekend markup, but it does not promise a better rate. Monday's rate can open higher or lower than Friday's, and nobody knows which in advance. If the amount is small, the weekend cost is usually not worth the time you would spend thinking about it. If the amount is large, such as a deposit on a flat abroad or a car, it makes sense to convert on a weekday, when quotes are tightest.
The same logic applies to cash for a trip. If you need foreign banknotes for a Monday flight, ordering them during the week costs less than buying them at a kiosk on Sunday. If you plan to withdraw from an ATM after you land, the day of the week matters only if your card adds a weekend fee.
A simple weekend routine
- Check Friday's close first. Open the pair in WaveRate and look at the chart. On a weekend the latest rate is, in effect, Friday's close, and that is your benchmark.
- Read the provider's fee page for weekends. If you use a money app, check whether it adds a markup on Saturdays and Sundays. If it does, a weekday conversion is the cheap option.
- Measure any quote against the benchmark. Type the amount into WaveRate's calculator, compare it with what the bank or exchange office offers and you will see the provider's whole markup in money, not in percentages.
- Log trip spending with its own date. If you track a trip in WaveRate, each expense keeps the reference rate of its day, so weekend purchases are recorded honestly next to weekday ones.
Questions people ask
Do exchange rates change on Saturday and Sunday?
Market rates barely move, because interbank currency trading is closed from Friday 5 pm New York time until Sunday evening UTC. The rate you see on a weekend is essentially Friday's closing rate. What can change is the price a bank, an app or an exchange office offers you.
Is it more expensive to exchange money on the weekend?
It can be. Some money apps add a weekend fee of 0.5 to 2%, and exchange offices may widen their spread to protect themselves against Monday's rate. Check the provider's fee page and compare the quote with the mid-market rate before converting a large amount.
When does the currency market open again after the weekend?
Trading resumes on Sunday evening UTC, which is Monday morning in New Zealand and Australia. Asian markets follow a few hours later, then Europe and New York. Large weekend news shows up first in that Sunday-evening session.
Do card payments cost more on weekends?
Not because of the card network. Visa uses the rate set before the weekend and Mastercard the rate in effect when the payment is authorised, and neither adds a weekend markup. Some banks and money apps add their own weekend fee, so check your card's terms.
Which exchange rate applies to a date that falls on a weekend?
Official reference rates, such as the European Central Bank's, are not published on weekends or holidays. For accounting or tax purposes the usual approach is to use the last published rate before that date, but follow the rule your tax authority or employer sets.
Should I wait until Monday to convert money?
Only if your provider charges extra on weekends or the amount is large. Monday's rate can be better or worse than Friday's, and nobody can predict which. Waiting avoids a weekend markup; it is not a bet on the rate.
