Stablecoins process $33 trillion, Mastercard buys BVNK for $1.8

Stablecoins moved $33 trillion in on‑chain transactions in 2025, eclipsing the $25.5 trillion handled by Visa and Mastercard, and the surge is now driven by B2B payments rather than speculative trading【1】.

Shift from trading to payments

The $33 trillion figure includes a growing share of genuine economic activity. While exchange‑driven flows still exist, B2B stablecoin payments rose from under $100 million per month in 2023 to more than $6 billion by mid‑2025, now accounting for roughly 60 % of “real” stablecoin usage【1】. Companies are adopting stablecoins for supplier payments, treasury management, and cross‑border settlements, with 77 % of surveyed firms already using them and 41 % reporting cost savings of at least 10 %. This transition from speculative noise to a payment‑focused use case underpins the volume jump and suggests a structural shift.

Infrastructure bets by incumbents

Traditional card networks are moving from defensive postures to active builders. In March 2026, Mastercard agreed to acquire BVNK, a London‑based stablecoin‑infrastructure firm, for up to $1.8 billion—its largest stablecoin deal to date【1】. BVNK provides the “plumbing” that links fiat systems to blockchain, enabling instant transfers across 130 + countries. The deal follows Stripe’s $1.1 billion purchase of Bridge in early 2025, marking two back‑to‑back billion‑dollar bets on stablecoin infrastructure within a year【1】. These acquisitions signal that incumbents see stablecoins as a core component of future payment stacks rather than a peripheral threat.

Regulatory tailwinds

Regulation is reinforcing the payment narrative. The U.S. GENIUS Act, enacted in July 2025, reclassified stablecoins issued by permitted entities as payment instruments, allowing banks to issue them and clarifying reserve requirements【1】. Stablecoin issuers now hold $155 billion in U.S. Treasury bills, surpassing the sovereign holdings of Germany and Saudi Arabia, a profile more akin to systemic financial infrastructure than speculative assets【1】. Similar moves in Europe (MiCA) and Asia (Singapore, Hong Kong, Japan) are creating a globally consistent regulatory environment that encourages institutional adoption.

What to watch

• Monitor the rollout of Mastercard’s BVNK platform and any announced pricing or partnership details (Q4 2026).
• Track the next regulatory milestone in the U.S., such as the Treasury’s final reserve‑requirement rules expected in early 2027.
• Watch on‑chain B2B stablecoin volumes for a breach of $10 billion per month, which would further validate the payment‑centric growth trajectory.

The $33 trillion milestone proves stablecoins have moved beyond trader‑only utility; they are now a parallel payment rail that traditional networks are actively integrating. The open question is how quickly the broader financial ecosystem will align its infrastructure and compliance frameworks to accommodate volumes that could reach $50 trillion by 2026.
