Jaffna's economy is traditionally rooted in agriculture and fisheries, though it has seen steady growth in retail, services, and light industry in recent years. Remittances from the global Sri Lankan Tamil diaspora play a substantial role in the local economy.
- **Agriculture & Fisheries**: Major cash crops include red onions, tobacco, mangoes (particularly the *Karuthacolumban* variety), bananas, and palmyra products. The coastal areas support a robust fishing industry. - **Industrial & Commercial Hubs**: The **Achchuveli Industrial Estate** is a key zone designed to boost light manufacturing and garment production. - **Retail**: The central business district around Hospital Road and KKS Road is bustling with local merchants, jewelry stores, and textile shops, particularly near the iconic Jaffna Market.
