The surge in the NT dollar resembles a "train losing speed," as the public rushes to exchange currency, leading to significant congestion in online banking. This morning (May 5), the NT dollar briefly reached 29.37 against the US dollar, rising 1.54 cents, prompting many to immediately use their mobile apps for currency exchange, resulting in traffic jams across several banks including Cathay United Bank, Chinatrust Commercial Bank, Mega International Commercial Bank, and Taishin International Bank.

Yushan Bank was the quickest to respond, confirming that increased currency exchange and login traffic caused the congestion, but reported that by around 11 o'clock, the system had returned to normal. Mega International Bank stated that they could not verify whether users logging in were actually exchanging currency, but confirmed the congestion. Cathay United Bank mentioned that customer inquiries about exchange rates were well above normal levels and had implemented a queueing system to maintain stability.

This morning, the NT dollar opened at 30.91 in the Taipei foreign exchange market and rose suddenly by over one dollar in just 15 minutes to reach 29.37. Alert citizens closely monitored the market, swiftly opening their apps to start exchanging, only to find that many banks were congested, requiring several extra minutes to complete transactions compared to normal. Cathay United's CUBE app faced connectivity issues, which were being actively addressed. Yushan Bank reported that fluctuations in exchange rates and a surge in usage had caused slowdowns in their mobile banking app, but service had been restored. Mega International Bank emphasized that while they could not confirm the reason behind the logins, significant congestion was indeed present across several banks’ apps.
