Are stablecoins now the core plumbing of global finance?

Stablecoins have “quietly become core financial plumbing” and pushed on‑chain finance past a “point of no return,” according to a new a16z crypto framework that recasts programmable dollars as the base layer for a multi‑chain, banking‑as‑a‑service stack and a coming wave of on‑chain credit.

Stablecoins have quietly become core financial plumbing and pushed on-chain finance past the “point of no return,” according to a new framework report from a16z crypto. Titled “The New Stack of Global Finance: The Stablecoin Edition,” the analysis argues that what started as a niche trading tool has morphed into a global settlement layer and a new kind of “banking as a service” stack that is already reshaping how money moves.

In the report, a16z crypto writes that stablecoins have evolved into “fundamental financial pipelines,” with programmable dollars now embedded in consumer apps, fintech platforms, and institutional workflows. The firm describes a new BaaS model in which on-chain issuers and infrastructure providers offer “instant, API‑native balance sheet services” that sit beneath wallets, exchanges, neobanks, and even traditional institutions.

“The transition to on-chain finance has crossed the point of no return,” the authors conclude, arguing that even if prices correct, the underlying rails will continue to scale in volume and sophistication.

The report slices today’s blockchain landscape into three core categories: general-purpose chains like Ethereum, Solana, and layer‑2 networks; payment‑specific chains such as Stripe’s Tempo; and institutional networks like Canton, which target regulated participants and permissioned workflows.

Each category, a16z says, is increasingly tethered together by stablecoins that act as the common settlement asset, whether the end user is a retail gamer or a global bank.

On the banking side, a16z pushes back on the idea that regulatory bottlenecks are still insurmountable. “The bottlenecks in the banking industry are easing,” the report notes, pointing to a growing roster of crypto‑friendly banks actively wiring on‑chain infrastructure into fiat payment systems.

At the same time, the competitive frontier for issuers has shifted from raw market share to regulatory positioning, with leading stablecoin firms “vying to obtain OCC national trust charters” and other licenses that would anchor them more firmly inside the U.S. banking perimeter.

Crucially, the paper frames payments as only “the first act.” The more important “second act,” in a16z’s view, will be credit.

“The large‑scale issuance of stablecoins will give rise to a new on‑chain credit market, allowing capital to form outside the traditional banking system,” the report says, predicting that on‑chain collateral, reputation systems, and programmable covenants will underpin a parallel credit stack layered on top of stablecoin rails.

Finally, the authors stress that this is not just a crypto story, but a geopolitical one.
Stablecoins, they argue, “enhance the dominance of the dollar” by exporting dollar access into any app or wallet with an internet connection, while simultaneously giving emerging‑market users a more direct, censorship‑resistant channel into the U.S. currency than their domestic banking systems typically provide.
