A migrant worker in Dubai sending $200 home to the Philippines through a traditional remittance channel will pay an average of $12 to $14 in fees and wait one to three business days for the money to arrive. The same transfer through a blockchain-based service like Coins.ph or GCash settles in minutes at a fraction of the cost. This gap explains why blockchain is reshaping the $371.59 billion cross-border payments market. The market is projected to reach $727.74 billion by 2034, growing at 7.90% CAGR, according to Fortune Business Insights. Blockchain-based networks already handle approximately $3 trillion in annual cross-border payment volume, representing 27% of the total, per Coinlaw.
The Correspondent Banking Problem
Cross-border payments have been slow and expensive for decades because of how the correspondent banking system works. When a company in Germany pays a supplier in Vietnam, the payment does not travel directly between banks. It passes through a chain of intermediary banks, each of which holds accounts with the next bank in the chain.
A typical payment might route from the sender’s bank in Frankfurt to Deutsche Bank, then to Citibank in New York (as a dollar clearing bank), then to a regional correspondent bank in Singapore, and finally to the recipient’s bank in Ho Chi Minh City. Each intermediary adds processing time, deducts a fee, and applies its own compliance checks. The sender may not know the total cost until the payment arrives.
Data from Chainalysis’s 2024 Global Crypto Adoption Index shows that emerging markets in South and Southeast Asia continue to lead grassroots cryptocurrency adoption, driven by remittance use cases and limited access to traditional banking services.
According to CoinGecko’s 2024 annual crypto report, total cryptocurrency market capitalisation exceeded $3.5 trillion by the end of 2024, reflecting renewed institutional interest following spot ETF approvals in the United States.
SWIFT, the messaging network that connects over 11,000 financial institutions across 200 countries, coordinates this process but does not move money itself. SWIFT messages instruct banks to debit and credit accounts, but actual settlement depends on each bank in the chain completing its own processes. A single compliance hold at any intermediary can delay the entire payment by days.
The World Bank reports that the global average cost of sending $200 internationally was 6.2% in Q3 2024. For some corridors, particularly those involving Sub-Saharan Africa, the cost exceeds 8%. These fees fall disproportionately on migrant workers and small businesses that can least afford them.
How Blockchain Eliminates Intermediaries
Blockchain-based payment networks allow funds to move directly between sender and recipient on a shared ledger, eliminating the chain of correspondent banks. The payment settles when the network confirms the transaction, which takes seconds to minutes depending on the blockchain used.
RippleNet is the most established institutional blockchain payment network. It connects over 300 financial institutions across 55 countries. Payments on the XRP Ledger settle in three to five seconds. RippleNet provides real-time exchange rate quotes before a transaction is initiated, so the sender knows the exact cost. There are no hidden intermediary fees because there are no intermediaries.
Stablecoins provide an alternative path. Circle’s USDC and Tether’s USDT, with combined market capitalisation exceeding $150 billion, are used for cross-border B2B payments, remittances, and trade settlement. A company can convert local currency to USDC, send it to a counterpart’s blockchain wallet, and the recipient converts back to their local currency. The entire process takes minutes and costs a fraction of a cent in network fees on low-cost chains like Solana, Tron, or Polygon.
Stripe’s $1.1 billion acquisition of Bridge in October 2024 brought stablecoin payment infrastructure into the mainstream payments ecosystem. Bridge allows businesses to send and receive payments in stablecoins through a standard API, without requiring either party to manage blockchain wallets or understand the underlying technology. The blockchain is invisible to the end user.
Corridor-Level Impact
Blockchain-based payments are growing fastest in corridors where traditional infrastructure is weakest and fees are highest.
The US-to-Philippines corridor, one of the largest remittance routes globally, processes over $30 billion annually. Coins.ph, a blockchain-based financial services app acquired by a consortium led by Bain Capital in 2023, allows overseas Filipino workers to send money home through blockchain rails. Recipients access funds through the app, converting to Philippine pesos at their local 7-Eleven or partnered agent.
The UAE-to-India corridor processes approximately $50 billion in annual remittances. LuLu Exchange and Al Ansari Exchange, two of the largest exchange houses in the Gulf, have partnered with RippleNet to offer blockchain-based transfers that settle in minutes rather than the one to two days required by traditional channels.
Intra-African payments are another area of rapid adoption. Transferring money between Nigeria and Kenya through traditional banking channels is slow and expensive, often routing through London or New York because direct correspondent banking relationships between African banks are limited. Companies like Chipper Cash and Flutterwave use blockchain-based settlement to enable direct transfers between African countries, bypassing the need for offshore clearing.
Latin America shows similar patterns. Bitso, a cryptocurrency exchange based in Mexico, processes a significant share of US-to-Mexico remittances through blockchain rails. The company partners with traditional remittance providers who use Bitso’s blockchain infrastructure for settlement while maintaining a familiar customer-facing experience.
Central Bank Digital Currencies and Cross-Border Settlement
Central banks are developing their own blockchain-based solutions for cross-border settlement. Project mBridge, a collaboration between the BIS Innovation Hub and the central banks of China, Thailand, the UAE, and Hong Kong, tests a multi-CBDC platform for cross-border payments. The platform allows participating central banks to settle transactions directly, without using the US dollar as an intermediary currency.
Project mBridge completed its minimum viable product phase in 2024, demonstrating that cross-border payments between participating countries could settle in seconds rather than days. The geopolitical implications are significant: a functioning multi-CBDC platform would reduce reliance on the dollar-based correspondent banking system for trade between participating nations.
The Bank of England, Banque de France, and Swiss National Bank have conducted separate experiments under Project Jura and Project Dunbar, testing how CBDCs issued by different central banks can interoperate on shared blockchain platforms. These experiments confirmed that multi-currency settlement on blockchain is technically feasible, though regulatory and governance frameworks for production deployment remain under development.
China’s digital yuan (e-CNY) has processed over 7 billion yuan in transactions domestically, with cross-border applications being tested in Hong Kong and parts of Southeast Asia. If the digital yuan achieves widespread cross-border acceptance, it would provide an alternative to SWIFT for trade settlement in Asia, one of the fastest-growing trade regions globally.
What SWIFT Is Doing in Response
SWIFT is not ignoring blockchain. The network began testing blockchain interoperability in late 2023, with over 30 financial institutions participating. The initiative aims to create a bridge between private blockchain networks used by different banks, allowing them to exchange value across otherwise incompatible systems.
SWIFT also launched pre-validation capabilities that check beneficiary account details before a payment is sent, reducing the rate of failed transactions. In 2024, SWIFT reported that 89% of cross-border payments on its network now arrive within an hour, up from 40% in 2020. This improvement came from better routing and pre-screening, not from blockchain technology, but it demonstrates that traditional rails are improving in response to blockchain competition.
The competitive dynamic is producing better outcomes for users regardless of which technology wins. Traditional rails are getting faster. Blockchain rails are getting more accessible. The ultimate structure may be hybrid: SWIFT connecting blockchain networks to each other and to the existing banking system.
Remaining Barriers
Regulatory fragmentation is the largest obstacle. A blockchain-based payment from the US to Nigeria must comply with US anti-money laundering laws, Nigerian foreign exchange controls, and potentially intermediate jurisdictions’ regulations. Each country has different requirements for identity verification, transaction reporting, and foreign exchange controls. The EU’s MiCA regulation provides a unified framework for digital asset transactions within Europe, but no equivalent global standard exists.
Liquidity in emerging market currency pairs is another constraint. Converting USDC to Nigerian naira or Indonesian rupiah requires on-ramps and off-ramps, exchanges or agents that will buy stablecoins and dispense local currency. In major corridors, this liquidity exists. In smaller corridors, it does not, limiting blockchain’s reach to the markets that need it most.
The cross-border payment volume growing at 45% annually on blockchain networks suggests these barriers are being overcome faster than they are being reinforced. For the $727.74 billion market projected by 2034, the question is not whether blockchain will capture a significant share. The question is how much of that share will flow through private institutional networks, public stablecoin rails, or central bank digital currencies.
