According to Bloomberg, South African Reserve Bank Governor Lesetja Kganyago warned that with the rising use of stablecoins, cryptocurrencies may face a risk of "fragmentation." He stated at the 2026 Warwick Economic Summit that central banks have a responsibility to maintain monetary unity and ensure the public's access to affordable currency, and that the development of stablecoins could pose a challenge to this goal. Kganyago pointed out that stablecoins have recently been used more in South Africa as low-volatility crypto assets, and the South African Reserve Bank had previously warned in November 2025 about the financial risks posed by insufficient regulation. Additionally, he emphasized that amid rising global uncertainties and the U.S. imposing tariffs, central banks need to rely on diversified financial models to respond to changes.
