The Curious Case of the Stablecoin Sandwich (LinkedIn)
G+D’s Lars Hupel posted an article on LinkedIn that argues that the “stablecoin sandwich” model for cross‑border payments—converting local currency to a (mostly USD) stablecoin, sending it on‑chain, then converting back—largely replicates traditional correspondent banking rather than solving its hardest problems, because liquidity is concentrated in a few USD‑denominated stablecoins and most currencies lack deep stablecoin markets, so efficiency gains are modest and partly driven by regulatory arbitrage rather than technology; meanwhile, central banks are pursuing more promising alternatives like interlinking instant payment systems, broadening access to real-time gross settlement systems (RTGSs) to non‑banks, and building multilateral central bank digital currency (CBDC) platforms such as mBridge and Project Agorá, which more directly tackle fragmentation and access in cross‑border payments.

Stablecoins Are Coming for FX Markets (Delphi Digital)
Delphi Digital argues that dollar stablecoins are rapidly gaining share in FX, especially in long‑tail emerging market corridors where legacy correspondent banking makes cross‑border payments slow and expensive, with most costs driven by infrastructure rather than FX risk. In corridors like Argentina or Nigeria, fees and spreads are largely compensation for pre‑funded nostro/vostro accounts, delayed settlement, credit risk, and multiple intermediaries, so stablecoin rails that offer atomic, near‑instant settlement in tokenized dollars can undercut banks and keep corridors viable. The piece highlights that new infrastructures show how on‑chain FX could settle in seconds instead of days. However, it stresses that fiat on/off‑ramps remain the main bottleneck, since bank wires still run on legacy batch rails and regulatory frictions, implying that stablecoins will not displace major FX pairs soon but are already rebuilding broken payment rails in under‑served corridors.

I produce a monthly digest of digital fiat currency (DFC) developments exclusively for the official sector (e.g., central banks, ministries of finance and international financial institution (e.g., the BIS, IMF, OECD, World Bank)) plus academics and firms that are active in the DFC space (commercial banks, technology providers, consultants, etc.). (DFCs include central bank digital currency (CBDC), stablecoins and tokenized deposits.) It goes out via email on the first business day of every month, and if you’re interested in being on the mailing list, please email me at john@kiffmeister.com.
