South Korea’s Bank of Korea (BOK) manufacturing Business Survey Index (BSI) rose to 72 in May. It was 71 in the previous reading.
We see the manufacturing business outlook has improved slightly to 72 for May, marking a small but positive step from April’s 71. While this figure remains well below the neutral 100-point mark, indicating pessimism still outweighs optimism, the upward trend is what matters. This aligns with recent data showing South Korea’s exports rose for the sixth straight month in March 2026, driven by a 35% year-on-year surge in semiconductor shipments.
For those trading the Korean won, this small improvement in sentiment provides a weak but supportive floor for the currency. We could consider positioning for a stable or slightly stronger won against the US dollar in the coming weeks. Derivative plays might involve selling out-of-the-money USD/KRW call options to collect premium, betting that the won will not weaken significantly from current levels.
This news reinforces a cautiously optimistic view on the KOSPI 200 index, which is heavily weighted towards manufacturers like Samsung Electronics and SK Hynix. Looking back at the semiconductor-led recovery that started in 2025, this data suggests the momentum may continue. We might see traders use this as a signal to buy short-dated call options on the index, anticipating a modest rally.
Given the incremental nature of this improvement, we don’t expect a major spike in market volatility; in fact, it suggests a steadying economic environment. This stability might reduce the pressure on the Bank of Korea to alter its interest rate policy in the near term. Therefore, strategies that benefit from sideways movement or a slow grind higher, rather than explosive breakouts, could be favorable.
