Functions and programs
Sangha administration
Monk registration and monastic governance
ONB administers monk registration and the formal Sangha structure under the Sangha Supreme Council. Thailand's approximately 250,000 monks and novices are registered through ONB-administered temple systems. Monk ordination, disrobing, and disciplinary proceedings follow the Vinaya code as interpreted under ONB's administrative framework.
Temple governance
37,000-plus wat management and land oversight
ONB manages the administrative governance of Thailand's 37,000-plus Buddhist temples (wat), which collectively hold a significant portion of Thai communal land. Temple land is held in trust for religious purposes; ONB-administered rules govern temple-land use, rental, and development for commercial purposes.
Religious tourism
Temple and pilgrimage tourism coordination
ONB coordinates with the Tourism Authority of Thailand (TAT) on Buddhist heritage tourism, including major pilgrimage sites (Wat Phra Kaew, Doi Suthep, Phra Pathommachedi), religious festivals (Makha Bucha, Visakha Bucha, Kathin), and the development of Buddhist tourism corridors in major temple provinces.
Buddhist education
Monastic schools and Dhamma studies
ONB oversees Buddhist education through monastic schools (Pali studies, Dhamma studies) within temple compounds. The Dhammayuttika and Mahanikaya orders conduct Pali and Dhamma examinations administered under ONB frameworks. Monastic schools serve both ordained monks and lay students in rural communities.

Key drivers 2025-2026
Cremation
Temple cremation services and funeral economics
Thai Buddhist funerals rely on temple crematoriums, with merit-making ceremony packages generating significant revenue for temples. ONB's oversight of cremation permits and temple-hall scheduling affects the economics of Thai funeral service operators. COVID-era cremation surge revealed capacity constraints at urban temple crematoriums.
Religious tourism
Buddhist heritage tourism post-pandemic recovery
International Buddhist pilgrimage tourism to Thailand — from Japan, China, Sri Lanka, Cambodia, Myanmar — is recovering alongside general inbound tourism. TAT's Buddhist circuit marketing targets pilgrims visiting Ayutthaya, Chiang Mai, Nakhon Pathom, and northeastern temple complexes.
Reform
Sangha governance reform and transparency
Ongoing debates over temple-fund transparency, monk-welfare standards, and the legal framework for temple land use generate periodic reform pressure on ONB. High-profile cases of financial misconduct at major temples have led to calls for greater ONB oversight and auditing of temple financial accounts.
