Path of Exile 2's Currency Exchange is a vital tool for converting lower-tier currencies into higher-tier ones, facilitating player trades 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 way to check current rates is 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 features two currency selection boxes.
First, select the currency you want in the left box. For example, to find the Divine Orb price, choose Divine Orb from the list.
Next, choose the currency you have from the right box, which displays your available currencies from your inventory and stashes. To check the Divine Orb's Exalted Orb equivalent, select Exalted Orb.
The conversion ratio appears between the boxes. The number shown indicates how many Exalted Orbs you need to obtain one Divine Orb.
This process works in reverse too. If you want to convert a Divine Orb to Exalted Orbs, select Exalted Orb in the "Want" box and your Divine Orb in the "Have" box.
Remember, exchange rates are constantly changing, so check frequently for the best deals. If a specific currency combination isn't available (e.g., Divine Orbs for Scrolls of Wisdom), no ratio will be displayed, and the exchange won't be possible.
