Path of Exile 2's Currency Exchange is a vital feature, allowing players to trade currencies for higher-tier ones, either for personal crafting or player interactions. However, determining the current exchange rates can be tricky due to their constant fluctuation.
Because Path of Exile 2's currency exchange rates are dynamic and market-driven, the only reliable way to find the current rates is by checking 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.
In the left box, select the currency you desire—the currency you're aiming to obtain. For example, to find the Divine Orb price, select Divine Orb.
In the right box, choose the currency you possess and wish to exchange. Continuing the example, if you want to know the Divine Orb price in Exalted Orbs, select Exalted Orb from your available currencies.
The conversion ratio will appear between the boxes. The displayed number of Exalted Orbs represents the cost of one Divine Orb.
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 changing, potentially fluctuating significantly within an hour. Regularly checking the exchange offers the best chance of securing favorable trades for valuable currency items.
If a specific currency combination isn't available (e.g., Divine Orb for Scrolls of Wisdom), no ratio will appear, indicating that exchange isn't currently possible.
