Market Volatility and Trading Volume Surge

While the BOK has maintained a cautious stance, expectations of potential rate hikes in the coming months have contributed to market uncertainty. Ongoing geopolitical risks, including tensions in Eastern Europe and the Middle East, continue to weigh on investor sentiment.
According to data from the Korea Financial Investment Association (KFIA), trading volume on the KOSPI market surged to over 5 billion shares on Wednesday, the highest level in several months. This surge in activity overwhelmed the capacity of some brokerage apps, leading to the reported system errors.

Brokerage App Performance and User Experience
