Watchpoints 2025–2026
Post-merger
A&O Shearman integration
The 2024 merger of Allen & Overy and Shearman & Sterling is still integrating practice groups, client-conflict systems, and billing structures. Bangkok office integration quality affects client-service continuity.
Bar restrictions
Foreign Lawyers Act limitations
Thailand's foreign-lawyer practice restrictions limit A&O Shearman Bangkok to advising on non-Thai law and international transactions. Any liberalisation under the Lawyers Council review would expand the firm's permitted scope.
Deal flow
Thai capital-markets activity
SET IPO and bond-issuance pipeline is linked to Thai interest-rate cycle and investor sentiment. Capital-markets revenue for international firms tracks SET issuance volumes closely.
