On-Demand Liquidity

What Is On-Demand Liquidity?

On-demand liquidity (ODL) is a payment approach that sources funds in a destination currency at the moment of transaction, rather than requiring pre-funded accounts in every country where payments need to be sent. By using a digital asset as a bridge currency, ODL converts the sender's local currency into the bridge asset, transfers it across a blockchain or protocol in seconds, and converts it into the recipient's local currency on the other end.

The term was popularized by Ripple, which branded its XRP-powered cross-border payment product as "On-Demand Liquidity" in 2019 (previously called xRapid). In 2023, Ripple consolidated the product under the name "Ripple Payments." However, the concept extends beyond any single provider: any system that uses a digital bridge asset to eliminate pre-funding qualifies as on-demand liquidity.

ODL addresses one of the most persistent inefficiencies in global finance: the trillions of dollars locked in pre-funded accounts that sit idle across correspondent banking networks, waiting for payment requests that may or may not arrive.

How It Works

Traditional cross-border payments require banks to maintain nostro accounts (accounts held at foreign banks in the local currency) pre-loaded with funds. When a customer in the U.S. wants to send Philippine pesos, the bank must already have pesos sitting in its nostro account at a Philippine bank. Estimates place between $10 trillion and $27 trillion globally in such pre-funded positions.

On-demand liquidity replaces this pre-funding model with a real-time conversion flow:

1. The sender initiates a payment in their local currency (e.g., USD)
2. A partner exchange in the originating country converts the source currency into a bridge asset (a stablecoin or cryptocurrency)
3. The bridge asset transfers across the underlying blockchain or protocol in seconds
4. A partner exchange in the destination country converts the bridge asset into the recipient's local currency
5. The recipient receives funds in their local currency

The bridge asset is held for only a few seconds during the transfer window. The institution acquires and disposes of it programmatically per transaction: the digital asset never sits on the institution's balance sheet for an extended period.

Compared to Correspondent Banking

In the traditional correspondent banking model, a payment from the U.S. to Thailand might pass through three or four intermediary banks, each performing compliance checks and extracting fees. SWIFT handles the messaging layer, but the actual value transfer relies on pre-funded positions at each hop. Settlement takes one to five business days and operates only during banking hours.

Settlement Flow Example

A simplified ODL settlement using a stablecoin bridge might follow this sequence:

// Simplified ODL settlement flow
// 1. Sender pays $1,000 USD
initiate_payment(sender, amount=1000, currency="USD")

// 2. Source exchange converts USD → USDC
usdc_amount = convert("USD", "USDC", 1000)  // 1,000 USDC

// 3. Transfer USDC to destination exchange (seconds)
tx = transfer(usdc_amount, from=source_exchange, to=dest_exchange)
// Settlement: ~3-5 seconds on-chain

// 4. Destination exchange converts USDC → PHP
php_amount = convert("USDC", "PHP", usdc_amount)  // ~56,200 PHP

// 5. Recipient receives PHP in local account
credit_recipient(recipient, amount=php_amount, currency="PHP")

Why It Matters

The global cross-border payments market processes roughly $200 trillion in annual flows. The World Bank reports that average remittance costs remain around 6.3% of a $200 transfer as of 2025, well above the UN Sustainable Development Goal target of 3%. About 25% of emerging market corridors charge over 10% in combined fees and FX conversion costs.

On-demand liquidity attacks this problem at its root: capital efficiency. By eliminating pre-funded positions, institutions free up working capital that was previously immobilized in foreign accounts. Smaller banks and payment providers benefit most, since they often lack direct correspondent relationships and must pay premium rates for multi-hop routing.

Use Cases

Remittance Corridors

Migrant workers sending money home represent one of the highest-volume, highest-fee corridors in global payments. Traditional remittance services charge steep margins on both the transfer fee and the FX spread. ODL providers can offer faster settlement at lower cost by bypassing intermediary banks entirely.

Key corridors include the U.S. to Mexico, the U.S. to the Philippines, and intra-Asia flows. Ripple's ODL product processes payments across 70+ currency corridors, with Asia-Pacific accounting for the largest share of volume. For more on how these corridors work, see the stablecoin remittance corridor analysis.

B2B Cross-Border Payments

Businesses making supplier payments, paying international contractors, or managing multi-currency treasuries face the same pre-funding problem at larger scale. A company paying suppliers in five countries traditionally needs nostro balances in each currency, tying up significant working capital.

ODL allows these payments to settle in seconds without maintaining foreign currency positions, converting funds only at the moment of payment.

Treasury Optimization

Corporate treasurers can use on-demand liquidity to reduce the cash held in foreign accounts, redeploying that capital into productive uses. Rather than forecasting demand across dozens of corridors and maintaining buffer balances in each, treasury teams hold a single pool of fiat or stablecoins and route payments dynamically.

Stablecoins as Bridge Assets

While Ripple's original ODL used XRP as its bridge asset, stablecoins have emerged as a compelling alternative for on-demand liquidity. Stablecoins maintain a fixed peg (typically to the U.S. dollar), eliminating the volatility risk inherent in using a market-priced cryptocurrency as a bridge.

Global stablecoin supply has grown to over $305 billion as of 2025, with transaction volumes exceeding $33 trillion annually. Major stablecoins used in cross-border ODL flows include:

• USDC: preferred by regulated institutions, MiCA-compliant in the EU, with $18.3 trillion in annual transaction volume
• USDT: dominant by supply (~59% market share), heavily used on TRON for low-cost emerging market transfers
• RLUSD: Ripple's own stablecoin, launched in December 2024 with NYDFS approval, integrated into Ripple Payments as an alternative to XRP
• USDB: a dollar-pegged stablecoin on Spark, combining instant settlement with Bitcoin's security guarantees

The shift toward stablecoins is significant: even Ripple launched its own stablecoin (RLUSD) to complement XRP, acknowledging that many institutions prefer a stable-value bridge asset. Stablecoins reduce settlement risk to near zero during the brief conversion window, since their value does not fluctuate.

Instant Settlement Protocols

Protocols that enable instant settlement further enhance on-demand liquidity by eliminating transit float entirely. When funds settle in seconds rather than days, the capital locked in transit shrinks to nearly zero.

The Lightning Network processes off-chain Bitcoin payments in seconds with sub-cent fees, bypassing traditional banking intermediaries. Spark, a Bitcoin Layer 2 protocol, takes this further by enabling instant self-custodial transfers of both BTC and stablecoins like USDB with zero on-network fees. The combination of stablecoins and instant settlement protocols provides ODL-like benefits without requiring any volatile bridge asset: the bridge itself is stable, and the settlement is final within seconds.

Risks and Considerations

Bridge Asset Volatility

When a volatile cryptocurrency like XRP serves as the bridge asset, even a few seconds of exposure creates slippage risk. Flash crashes or sudden price movements during the conversion window can erode the economics of a transfer. Stablecoins largely solve this problem, though they introduce their own depeg risk in extreme scenarios.

Exchange Liquidity and Counterparty Risk

ODL depends on partner exchanges in both the source and destination countries to provide conversion services. Thin order books in less liquid corridors can lead to significant slippage on larger transfers. Exchange insolvency, downtime, or regulatory action could disrupt entire corridors. Diversifying across multiple exchanges and bridge assets mitigates this concentration risk.

Regulatory Uncertainty

The regulatory treatment of digital bridge assets varies significantly by jurisdiction. While the U.S. Genius Act (2025) established a framework for payment stablecoins and the EU's MiCA regulation provides clarity in Europe, many emerging market corridors operate under evolving or unclear regulatory regimes. Institutions must navigate KYC/AML requirements, travel rule compliance, and local licensing mandates that differ across every corridor.

Settlement Finality

Not all blockchains offer the same finality guarantees. Probabilistic finality (as on Bitcoin L1) means a transaction could theoretically be reversed, creating risk for the destination exchange that converts bridge assets before settlement is truly final. Protocols with deterministic or near-instant finality reduce this window. Layer 2 solutions like Spark provide instant finality for transfers within the protocol, making them well-suited for ODL use cases where settlement certainty is critical.
