The euro moves against other currencies all the time. For someone reading a market report that is a curiosity. For someone earning in euros and paying expenses in pesos or soles, it is the difference between the month working out and not working out.
What moves the exchange rate
Three forces explain most of the movement, and they act at the same time.
The first is the expectation of relative interest rates. When the market starts pricing in that one economic area will cut rates sooner or faster than another, the gap between the two currencies narrows or widens, and the exchange rate adjusts to that expectation before the event happens.
The second is economic data: activity, inflation, employment. What matters is less the absolute number than its distance from what was expected.
The third is global risk appetite. In moments of tension money moves toward currencies perceived as safe havens, and that outweighs any local data point.
Why nobody can tell you what will happen
Because the three forces above move in different directions and none of them is observable in advance.
It is worth saying explicitly: we do not predict where a currency is going, and we would be skeptical of anyone claiming they can. What you can do is look at the applicable rate before confirming each transaction. How we work with market data and what we do not automate is in how we work with AI.
What it means for what reaches your family
The final amount is calculated at the point of conversion, so the rate at that moment feeds straight into what is received on the other side.
| Pair | Where to see the detail | What to look at |
|---|---|---|
| Euro and Argentine peso | euro to Argentine peso | The final amount in pesos, not the percentage |
| Euro and Peruvian sol | euro to Peruvian sol | The applicable rate before confirming |
| Euro and Colombian peso | euro to Colombian peso | Whether the local rail operates that day |
The decision that is actually yours
It is not timing the market. It is choosing which currency you express the transfer in.
If your family's expense is in local currency, send that amount in local currency and let the system work out the euros. The other way round, with the rate moving, one month falls short and the next overshoots. And avoid converting twice when once will do: every conversion has its margin, defined in the glossary.
The rest of the mistakes that add up month after month are in the mistakes that cost you money.
The euro as a reference currency
Something symmetrical happens on the other side of the corridor. People earning in local currency sometimes convert part of it into euros to hold value in a currency widely used in Europe, to prepare for a move, or to reduce exposure to local volatility.
There is no recommendation there either: it is picking the currency that matches the expense ahead. What it takes to hold a euro balance is on the European IBAN page, and the mechanics of the exchange in how the swap works.
Before confirming a conversion
Four checks and that is it: the applicable rate for that transaction, the amount left in the destination currency, whether the local rail operates that day, and the beneficiary name written exactly as on their ID.
That last one stops the most transactions. What happens when it fires is in why an account goes under review, and the timings of each route in SEPA, SWIFT and how long a transfer really takes.

Frequently asked questions
What makes the euro rise or fall against other currencies?
Mostly the expectation of relative interest rates between economic areas, activity and inflation data, and global risk appetite. When the rate gap between two currencies narrows, the one that was behind tends to gain relative ground. These are forces that move at the same time and in different directions.
Is there a good moment to convert euros into local currency?
There is no general answer, and be skeptical of anyone who gives you one. What is concrete: look at the applicable rate before confirming and decide on that basis. If the transfer covers a fixed monthly expense, the predictability of always sending the same amount in the currency of the expense usually beats trying to time it.
How does the exchange rate affect what my family receives?
Directly, because the final amount is calculated at the point of conversion. That is why it pays to express the transfer in the currency of the expense: if the rent costs a specific figure in local currency, send that figure and let the system work out the euros. The other way round, with the rate moving, one month falls short and the next overshoots.
Does BNKA recommend when to convert?
No. The role is operational: show the applicable rate before you confirm and execute what you decide. There is no advice on which currency to hold or when to convert, and rates are subject to market fluctuation until final confirmation.
