Airwallex CEO Jack Zhang has expressed skepticism about the practicality of stablecoins in reducing foreign exchange fees for cross-border payments. In a post on the X platform, Zhang highlighted that while investors frequently inquire about stablecoins' potential to lower costs, the conversion from stablecoins to local currencies often incurs higher fees than traditional interbank foreign exchange rates. Zhang further noted that despite the interest in cryptography, the sector has yet to demonstrate significant application cases over the past 15 years. His comments underscore ongoing debates about the efficiency and utility of stablecoins in the global financial system.
