BofA’s Pivot: End-Game of Index-Driven Won Sales

Bank of America has curtailed mechanical selling pressure on the Korean won, marking a pivotal shift in market dynamics.

The Zero Point of Dollar/​Won Turnaround

The Korean won, the worst‑performing currency in 2026, surged 8% unexpectedly. BofA’s regression model links this rally to a $5 billion net exit, capturing roughly a third of daily flow volatility.

The Reversal of Korea’s Stock Rally

■Kospi climbed to a record high, then fell 33%.

■Samsung and SK Hynix triggered automatic sales by exceeding upper limits.

■Excess exposure in emerging markets intensified the pull‑back from Korea.

Measuring Exits with the Regression Model

BofA’s model highlights a strong correlation between losses and risk appetite. It shows mechanical selling pressure approaching zero, while volatility remains the primary exit driver.

Global Funds Pulling Out of Korea

■Emerging markets outperformed, while Korean equities reversed.

■Global funds withdrew from Korea, tightening regional liquidity.

Potential Future Scenarios

■An uptick in the Dollar Index (DXY) could ease pressure on the won.

■Rising central‑bank interest‑rate differentials may restore regional currency flow.

■Performance of tech leaders will continue to shape market dynamics.

Markets are now in a search for equilibrium as BofA’s reduction in mechanical selling pressure signals a shift in risk perception, leading investors toward more stable currency pairs.
