Other Economic Notes
Reports indicate the Bank of Korea is assessing an October rate hike with current account trends, inflation and consumer sentiment as primary variables. US inflation shocks accounted for 41 percent of long-term rate synchronization between the two countries. Plans for a Korean won-only blockchain with embedded compliance features were announced alongside the Industrial Bank of Korea forming an AI Transformation Committee.
Prolonged inflation continues to pressure Korean American households. Samsung and SK Hynix near completion of share buybacks, reducing a key source of KOSPI support. Experts view the low 1,300-won range as Korea’s ideal exchange rate level.
Global Macro News
US inflation remains the dominant force linking Korean and US long-term yields, according to Bank of Korea analysis. The wider US-Korea rate gap has increased the probability of further Bank of Korea tightening. ↓ p.2
