The broad-based nature of these declines highlighted a pervasive lack of investor confidence across the board.

Rupiah Weakness and Trade Balance Weigh on IHSG
The primary catalysts for Wednesday’s market slump included the persistent weakening of the Indonesian rupiah against major currencies, a factor that often heightens investor concerns over inflation and corporate earnings. Additionally, the shrinking trade balance surplus further contributed to the negative sentiment, signaling potential challenges for the nation’s economic outlook and discouraging foreign investment.
Despite the widespread declines, a few stocks managed to defy the broader market trend, posting modest gains within the LQ45 index:
1. PT Mitra Adiperkasa Tbk (MAPI) edged up 0.67% to Rp 1,495 per share.
2. PT Indo Tambangraya Megah Tbk (ITMG) saw a slight increase of 0.34% to Rp 22,075 per share.

The Jakarta Composite Index (IHSG) experienced a significant downturn on Wednesday, June 3, 2026, plummeting by 4.11% to close at 5,941.06.
