Brunei has a small well-to-do economy that encompasses a mixture of foreign and domestic entrepreneurship, government regulation, welfare measures, and village tradition. Crude oil and natural gas production account for just over half of GDP and more than 90% of exports. Per capita GDP is among the highest in Asia, and substantial income from overseas investment supplements income from domestic production. The government provides for all medical services and free education through the university level and subsidizes rice and housing. A new monetary authority was established in January 2011 with responsibilities that include monetary policy, monitoring of financial institutions, and currency trading activities.
