Path of Exile 2's Currency Exchange is a vital tool for converting lower-tier currencies into higher-tier ones, facilitating player trading and crafting. However, determining the constantly fluctuating exchange rates can be tricky.
Because PoE 2's currency exchange rates are dynamic and market-driven, the only reliable method to check current rates for any currency combination is to do so in-game.
How to Check Currency Exchange Rates in PoE 2

To access the Currency Exchange, speak to the gambling vendor in any Act after reaching Cruel Difficulty. The exchange menu presents two currency selection boxes.
Select your desired currency: In the left box, choose the currency you want to obtain (e.g., a Divine Orb).
Select your available currency: In the right box, select the currency you possess and wish to exchange (e.g., Exalted Orbs).
View the exchange rate: The conversion ratio will be displayed between the boxes. This shows how many Exalted Orbs are needed to acquire one Divine Orb, for example.
This process works in reverse as well. If you want to convert a Divine Orb into Exalted Orbs, select Exalted Orb in the left box and your Divine Orb in the right.
Remember, exchange rates are constantly updating, leading to significant hourly variations. Regularly check for favorable deals on valuable currency items.
If a specific currency combination isn't available (e.g., Divine Orbs for Scrolls of Wisdom), no ratio will appear, indicating an invalid exchange.
