Compliance Becomes Real-Time for Fiat and Stablecoins

Payment infrastructure is getting faster and more interconnected. Now, compliance has to keep up. 

Fiat payments can move funds in seconds, while stablecoins now support 24/7 settlement. Through interoperable payment infrastructure, the two can also form part of the same journey, with value moving between stablecoin and fiat rails before funds reach the recipient.

That leaves less time to identify and act on risk, while also making the compliance task more complex. A single payment flow may require fiat-specific checks at one stage and on-chain controls at another, with risk context carried across both. 

Real-time compliance needs to move at payment speed without losing visibility as the transaction crosses rails.

Faster fiat and stablecoin payments are changing when compliance happens

Stablecoins entered 2026 at a very different scale. Supply grew by more than 50% in 2025, reaching $274 billion by the end of the year as their role expanded across payments, settlement and liquidity.

Research from Artemis and Castle Island Ventures found stablecoin payments were running at an annualised $72.3 billion by February 2025, with B2B payments accounting for $36 billion. Institutional adoption is also moving beyond experimentation: a Fireblocks survey of nearly 300 financial institutions found 49% were already using stablecoins, while another 41% were piloting or planning to use them.

A key factor is that clearer regulatory frameworks around stablecoins and digital liquidity are giving financial institutions more confidence to build around them.

Fiat infrastructure is accelerating at the same time through instant domestic payment systems and faster cross-border rails. In 2026, 71.7% of jurisdictions surveyed by Central Banking had an instant payment system in operation, up from 59% in 2024. According to the World Bank, people and businesses in 137 countries now have access to instant payment services on a 24/7 basis.

Across both fiat and stablecoin rails, this is changing what businesses and end users expect from global payments:

• Faster movement of funds across borders
• Payment operations that can continue beyond traditional banking hours
• Shorter settlement windows
• Faster access to funds for recipients
• Payment journeys that can move between fiat and stablecoin rails

Moreover, faster fiat rails and stablecoin payments are shrinking the window in which compliance decisions must be made. 

Real-time payment compliance needs to operate as part of payment execution, with screening and monitoring taking place before or during the transaction rather than after funds have already moved.

The challenge: Fiat and stablecoins create different compliance signals

What makes this complex is that fiat and stablecoin payments produce different signals for compliance teams to assess.

That means a single compliance approach can’t simply apply the same checks to both. Providers need controls that reflect the characteristics of each rail while still producing consistent risk decisions.

Hybrid payment flows make siloed compliance harder to manage

A cross-border payment doesn’t always remain within one financial environment from start to finish, and it can move between stablecoin and fiat rails as it is funded, converted and delivered.

It’s interoperability that allows these different payment environments to form part of the same journey. Stablecoin-to-local-rail connectivity can combine on-chain liquidity with fiat payout infrastructure, allowing value to enter through one rail and reach the recipient through another.

For example, a payment flow could look like this:

Stablecoin funding → on-chain screening → conversion → fiat payout → beneficiary screening → local payment rail

If fiat and stablecoin compliance sit in separate systems, that can cause a lack of transparency. Providers may find it harder to:

• Connect on-chain and off-chain activity
• Maintain consistent risk decisions across the payment lifecycle
• Investigate alerts with full transaction context
• Maintain a coherent audit trail
• Avoid manual hand-offs between compliance processes

Complicating things further is that the payment often has to be hybrid behind the scenes, as the end user only sees a single payout experience. That makes connected compliance important at the infrastructure level, even when the complexity is invisible at the point of payment.

What happens when compliance can’t keep pace?

Faster payments leave less time to identify risk and intervene before funds move. Hybrid payment flows add another layer of complexity: compliance may need to adapt from fiat controls to on-chain controls within the same transaction journey, while carrying relevant risk context from one stage to the next.

When compliance processes can’t operate at that speed or maintain that continuity, several problems can emerge.

1. Late intervention: A transaction may settle before screening or investigation identifies a reason to stop it.
2. Fragmented risk context: Risk identified on one rail may not be available when the payment moves to another.
3. More manual friction: Alerts and hand-offs between separate compliance processes can introduce delays into otherwise fast payment flows.
4. Slower payment experiences: If controls can’t make decisions quickly enough, compliance can become a bottleneck for instant and 24/7 payments.

Real-time compliance needs to do more than keep pace with payment speed. It needs to apply the appropriate controls as the transaction moves across rails, without losing sight of the wider risk context.

Compliance needs to follow the payment across rails

Unified compliance doesn’t mean applying identical controls to every rail. It means maintaining a consistent view of risk as money moves between them. 

What a connected compliance flow looks like

Treating compliance as a separate stage creates gaps in fast-moving payment flows. Risk checks need to sit within payment execution and respond to the rail, parties and transaction context involved.

Payment initiated
↓
Identify rail, parties and transaction context
↓
Apply relevant fiat and/or on-chain controls
↓
Approve, flag or block
↓
Execute payment
↓
Continue monitoring and retain audit records

The value of this approach is continuity. Risk information stays connected to the transaction as it moves across different rails and stages of the payment journey.

What the infrastructure needs to support

For that flow to work across fiat and stablecoin rails, providers need capabilities that can operate together while still responding to the characteristics of each payment:

• Real-time screening
• Continuous transaction monitoring
• Dynamic risk assessment
• Rail-specific controls
• Connected transaction records
• Consistent decisioning across markets and payment methods

The aim of real-time compliance is to stop the differences between fiat and stablecoin from creating separate risk blind spots.

Thunes connects payment speed with embedded compliance

If compliance needs to follow the payment across rails, the infrastructure supporting those payments needs to carry the controls with it. 

Thunes brings this together through interoperable payment infrastructure that connects fiat and stablecoin rails within its Direct Global Network, with Fortress Compliance embedding risk controls into the payment journey. Drawing on Tookitaki’s Fincense solution for real-time compliance checks and continuous risk management, the Fortress Compliance Platform enables seamless integration into global payment networks.

Fortress Compliance supports:

• Real-time sanctions screening: Screening takes place as payments move through the network.
• Dynamic risk scoring: Risk can be assessed using transaction context and behavioural signals.
• Travel Rule compliance: Supporting compliant virtual asset transfers where Travel Rule requirements apply.
• Regulatory coverage: Thunes operates under more than 50 licences worldwide.
• Connected compliance records: Screening, monitoring and transaction data can remain linked across the payment journey.

These features reduce the need to build a separate compliance stack every time a new funding or payout method is added. Payment speed can increase without compliance becoming disconnected from the transaction.

As fiat and stablecoin payment flows become more connected, compliance needs to remain just as connected across the full payment journey.
