Stablecoins, plumbing, and the brave new terrain of money
Personally, I think stablecoins are less about replacing money and more about reconfiguring the rails that money travels on. The recent conversation between Gary Liu and Liu Xiaochun—two voices perched at different ends of the US-China spectrum—offers a crisp lens on how a globalized, tech-driven financial system is being redesigned from the ground up. What makes this especially compelling is not a single “winner” in a tech arms race, but the realization that stablecoins are already the seams holding the entire digital asset ecosystem together. They’re the glue that makes rapid, cross-border, automated, and programmatic finance feel plausible at scale. If we step back, the central tension is not whether stablecoins are good or bad, but who gets to shape the rules, the infrastructure, and the guardrails that accompany them.
A new kind of plumbing for a digitized economy
What many people don’t realize is that stablecoins aren’t flashy end products as much as essential infrastructure. In Liu’s framing, the dominant current use of stablecoins is not for grand consumer applications but for “plumbing”—the backstage work that enables every on-chain trade to happen smoothly. He emphasizes that roughly 90% of stablecoin activity today is tied to this role: they serve as the stable counterparty that makes decentralized asset finance functional. Put differently, stablecoins are the reliable fuel that powers complex, multi-asset derivatives built on blockchain. Without that stable, universally accepted anchor, the orchestration of cross-asset trades would stall.
From my point of view, this reframing matters a lot. It shifts the conversation from “Are stablecoins a payment solution?” to “How resilient must the plumbing be for a booming, programmable economy?” If we treat stablecoins as a core public good—an infrastructure layer rather than a consumer product—then questions of oversight, resilience, and interoperability become central design challenges rather than political afterthoughts. This distinction also helps explain why both the US and China are racing to influence the rules while shaping the technical architecture that underpins global financial activity.
US and China: divergent paths, common anxieties
One thing that immediately stands out is how differently policymakers in the United States and China approach stablecoins, even as both seem to acknowledge their inevitability. In the US, the debate often centers on regulatory clarity, consumer protection, and financial stability. The instinct is to mitigate risk while preserving innovation, with a preference for broadly applicable standards that can scale across jurisdictions. In practice, that translates to a push for transparent reserve backing, independent audits, and clear separation between stablecoins used for everyday commerce and those serving more exotic DeFi architectures. What this really suggests is a choreography between innovation and guardrails: you don’t want to stifle technical progress, but you do want to prevent a fragility that echoes across the financial system when markets tremble.
China’s path, by contrast, has been more centralized and strategic. The emphasis is on aligning stablecoins with state objectives—monetary sovereignty, cross-border trade corridors, and the gradual integration of digital currencies into the renminbi ecosystem. The logic is not merely about stability in a few markets but about shaping an alternate, state-backed digital money regime that can compete with, or even supplant, private-sector rails if the public good requires it. From this perspective, stablecoins become a cudgel (and a shield) in a broader playbook of financial sovereignty and international influence. This is not about banning innovation but about directing it along channels that serve national strategic interests.
Hong Kong’s role: a sandbox with geopolitical gravity
Hong Kong’s emerging stablecoin licensing regime is less about a single product line than about the city serving as a working bridge between China’s domestic ambitions and global financial networks. In practice, a licensed stablecoin regime in Hong Kong could offer a relatively transparent, regulated corridor that foreign participants can access while still being tethered to the Belt-and- Road financial architecture. What makes this very interesting is the cultural and regulatory hybridity Hong Kong embodies: a common-law environment with deep Chinese capital markets integration. This hybridity positions Hong Kong to test cross-border custody, settlement, and interoperability protocols that can later feed into mainland China’s broader digital currency strategy.
From my vantage point, the Hong Kong experiment is more than a licensing exercise. It’s a live testbed for how to balance openness with control, market access with stability, and international participation with domestic policy priorities. If Hong Kong proves it can maintain robust oversight while enabling rapid, secure settlement of tokenized assets, it becomes a blueprint—not a mere outlier—for other jurisdictions wrestling with the same challenge: how to reap the benefits of digital money without surrendering financial safety or monetary sovereignty.
Deeper implications: a future where policy is architecture
What this discussion hints at is a broader shift in how we think about money, regulation, and national strategy. Stablecoins are no longer just a niche tech product; they are a critical interface between policy design and market operation. A few implications stand out:
- Interoperability becomes a national-security issue. If cross-border stablecoins bind multiple currencies and markets, the systems that govern them must be interoperable by design, with harmonized standards or at least predictable compatibility pathways.
- Resilience is a public good. The plumbing analogy is apt: a minor fault in a stablecoin’s reserve structure or settlement mechanism can cascade through markets that rely on it for liquidity. This elevates risk governance from a private-sector concern to a public-interest mandate.
- The distribution of influence will shape innovation. Whoever writes the rules—the US, China, or a coalition of major players—will steer which technical choices prevail (collateral types, reserve requirements, audit regimes, settlement speeds) and which communities flourish or stagnate.
- Public understanding lags behind technical reality. As these systems become more embedded in everyday commerce and institutional portfolios, the need for clear, accessible explanations grows. If people don’t grasp what stablecoins do and why governance matters, misperceptions about risk and control will intensify.
A larger trend: money as programmable infrastructure, not data in a wallet
If you take a step back and think about it, stablecoins embody a fundamental shift: money as programmable infrastructure rather than a static asset you carry. This reframes why these tokens matter. They are not merely digital dollars or euros; they are the canonical units that enable automated, cross-border value exchange with guarantees baked into the protocol. From this perspective, the debate becomes a question of who gets to set the rules that govern those guarantees and how they scale across borders, products, and communities.
What I find most provocative is the human element behind all these systems. People assume policy is about speed bumps and compliance checklists, but the deeper work is about trust architecture. Who do we trust to hold reserves? How do we verify that trust? What happens when trust is fractured? These questions are not abstract; they determine whether a global digital economy can actually function in times of stress, or if it buckles under a single shock.
Conclusion: a provocative moment for the global financial order
The current moment reads like a tightrope walk between innovation and governance, between national interests and global liquidity, between privacy and oversight. Stablecoins, as Liu and Liu observe, sit at the intersection of this balance. Personally, I think the trend toward treating stablecoins as plumbing rather than flashy product giants is the most honest, pragmatic starting point. It acknowledges their indispensable role while forcing a candid conversation about resilience, interoperability, and sovereign interests.
What makes this particularly fascinating is the realization that these digital instruments will inevitably become a factor in shaping geopolitical power. If Hong Kong’s licensing regime proves effective, it could accelerate a broader, regional standardization that makes digital money a shared public good rather than a Tencent-sized loophole for traders. In my opinion, the deeper question is whether we can build robust, globally acceptable governance that preserves innovation without letting systemic risk slip through the cracks.
If you take a step back and think about it, the future of stablecoins will track how well different jurisdictions align on the basics: transparent reserves, verifiable audits, and interoperable settlement. A detail I find especially interesting is how different regulatory cultures interpret transparency. The US tends toward disclosure and independent verification; China emphasizes state-backed control and strategic alignment. The best path forward might be a mosaic: a core set of universal standards for stability and risk, coupled with flexible, jurisdiction-specific guardrails that reflect local policy priorities.
Ultimately, what this really suggests is that stablecoins will become a litmus test for how societies balance openness with decisiveness in the digital age. The winners won’t simply be the fastest builders, but the most thoughtful architects of a money system that can survive shocks, travel across borders, and earn public trust in an era when trust itself is both digital and political.
