USDC (USDC) became part of a Colombia-focused settlement pilot announced by ACI Worldwide and Circle on October 27, 2026. The Circle announcement describes a test of stablecoin settlement alongside existing banking and payment infrastructure. The USDC price trades at 1.0010 USD as of October 29, 2026, according to Investing.com.

ACI connects USDC to Colombia payments

The initiative combines ACI Connetic, a cloud-based payments orchestration platform, with Circle's USDC infrastructure. The first market is Colombia, where ACI built infrastructure for Bre-B, an interoperable instant-payments ecosystem. The companies say financial institutions can evaluate stablecoin settlement through payment systems they already use, rather than operating a separate settlement stack.

The October 27, 2026, announcement describes the work as a demonstration rather than a completed nationwide rollout. It covers traditional payment methods, card payments and digital assets through one platform, giving institutions a framework to assess settlement models and operating requirements.

MiCA share and supply move apart

USDC also holds 56 percent of stablecoin trading against the euro, according to LCX, which cited Kaiko data on October 27, 2026. The same report said USDC's euro order books were 40 percent deeper than those of USDT. This measure concerns dollar-pegged stablecoins traded against the euro and does not represent total global stablecoin supply.

A counterpoint came from CryptoTicker on October 28, 2026. It reported that USDC circulation had declined by 4.08 billion USD over 30 days to 71.30 billion USD in tokens. The report linked the decline to redemptions exceeding new issuance during that period.
