My base currency is USD. I want to change according to customer-group i.e. If customer group "Retailer" the currency =EUR.

So far I managed to get customer's group code:

$groupId = Mage::getSingleton('customer/session')->getCustomerGroupId();
$customer = Mage::getModel('customer/group')->load($groupId)->getCustomerGroupCode();

if($customer == 'Retailer') { /* Change currency to EUR */ }

Any help would be appreciated!

You can use an observer and set currency is below way. You just have to set your customer group ID here: if ($groupId == 1)


<?xml version="1.0" encoding="UTF-8"?>


class My_Module_Model_Observer extends Mage_Core_Model_Observer
    public function changeCurrency(Varien_Event_Observer $observer)
        $groupId = Mage::getSingleton('customer/session')->getCustomerGroupId();
        if ($groupId == 1) {
        } else {

    You can consider controller_action_predispatch as the first event dispatched in magento. Although there are few others. So It will check your customer group and set the currency in store front runtime. You can also check this event controller_front_init_before.
