Equity markets across Southeast Asia rallied this week after member states signed a regional trade pact that lowers tariffs on technology and agricultural goods. Benchmark indexes in several capitals posted their strongest weekly gains of 2026. Analysts said the agreement could deepen regional supply chains and attract manufacturing investment, particularly in electronics and food processing. Exporters were among the biggest beneficiaries. Currency markets were calmer, with traders focusing on the longer-term boost to intra-regional trade rather than immediate flows.
