What is the largest source of foreign exchange in the Philippines?

The largest source of foreign exchange in the Philippines is the remittances sent by Overseas Filipino Workers (OFWs). These remittances significantly contribute to the country's economy, providing a vital source of income for many families and supporting local businesses. In recent years, remittances have consistently outpaced other sources of foreign exchange, such as tourism and foreign direct investment. This reliance on remittances underscores the importance of the Filipino diaspora in the national economy.
