From Check Float Arbitrage to Stablecoins: Blockchain Optimizes Corporate Finance

Woofun AI reports that the transition from manual settlement delays to automated blockchain efficiency has fundamentally reshaped corporate finance, with entities like Siemens, Airbus, Goldman Sachs, Deel, Kinexys, BlackRock, Bodry, CME, Google Cloud, HSBC, Maersk, BNP Paribas, we.trade, TradeLens, Marco Polo Restaurants, Contour, XDC Network, Komgo, Tether, Circle, Coinbase, eWpG, and KfW navigating this shift. Thejaswini M A, compiled by Block unicorn, traces this trajectory from the arbitrage opportunities of the 1970s to the current era of tokenized assets and stablecoin-driven payroll systems.

In the 1970s, American corporations exploited the latency of physical check clearing for financial gain, a practice termed remote payment. Buyers in New Jersey would issue checks drawn on obscure banks in Montana, leveraging the thousands of miles and additional processing steps to delay fund availability. With interest rates exceeding 10%, retaining funds for extra days generated significant profits, leading consultants to map small-town banks with the longest settlement times. This model relied on massive transaction volumes; Americans issued 8 billion checks in 1970, rising to 16 billion by 1980.

The Federal Reserve’s floating funds—money existing in two places simultaneously—averaged $3 billion daily in 1972 and more than doubled between 1975 and 1978. Outraged, the Federal Reserve released a report on remote payment in February 1979, followed by a policy statement ordering banks to cease facilitating such operations. The Currency Control Act of 1980 mandated the complete elimination of this practice, and twenty years later, the Check 21 Act finally ended it. Today, most checks settle within a single business day, with the Federal Reserve handling all checks from a building in Atlanta, marking the end of an era defined by geographic arbitrage.

The operational scale of modern corporations underscores the complexity that blockchain aims to simplify. Siemens employs over 12,000 people in more than 80 countries, with its global business services department managing invoices, payroll, and account reconciliation. Airbus established an office in Lisbon in July 2021, and its center along with industrial units now employ over 1,000 people in Portugal. Goldman Sachs maintains a workforce of 47,400 employees. These vast organizational footprints highlight the inefficiencies inherent in traditional cross-border financial operations, setting the stage for technological intervention.

Siemens’ adoption of blockchain for bond issuance illustrates the speed and security of modern settlement mechanisms. In February 2023, Siemens issued €60 million on the Polygon platform, with settlement occurring two days later. Eighteen months later, in September 2024, Siemens issued €300 million in bonds, completing settlement within minutes through blockchain. This second issuance converted the public crypto network SWIAT into SWIAT tokens, a closed ledger created by a consortium of European banks for institutional transactions.

Regulatory compatibility allowed integration with the Deutsche Bundesbank’s trigger solution, enabling automatic settlement of the entire €300 million in central bank currency within minutes. Investors subscribed directly and saw registration details immediately after settlement. Peter Raschegb, the company’s finance director, oversaw both issuances, with the second virtually eliminating settlement risks for all parties. Typically, institutions like Clearstream would handle such securities, but no employee at Clearstream lost their job over this German bond, demonstrating the seamless integration of new technology with existing financial roles.

Deel, a payroll service provider, is leveraging stablecoins to optimize global salary management for over 40,000 companies and 1.5 million employees across more than 150 countries/regions, handling annual transactions worth over $22 billion. Starting from January 2026, companies will be able to use stablecoin wallets to pay all global salaries. In June 2026, Deel launched its dollar-backed digital balance, DLUSD. Employers face challenges such as liquid assets trapped in overseas accounts, failed remittances, conversion fees, and manual reconciliation.

For workers in Argentina, Turkey, and Ukraine, wages paid in local currencies can depreciate by 20% to 40% within a year. In 2025, 85% of Argentine contractors working for Deel chose to receive wages in dollars. In June of this year, Deel provided dollar balances in their app, built on Bridge, Privy, and Tempo platforms, offering rewards for idle funds. In May, the company began paying full-time employees in the U.S. and eurozone using stablecoins issued on the Polygon platform, amounting to 10% to 25% of their net wages.

Market adoption of stablecoins is accelerating, supported by solid data. A survey by EY and Paton among 350 corporate executives found that 13% of companies had already adopted stablecoins. Among them, 41% achieved cost reductions of over 10% in cross-border B2B payments, saving $50 million on a $50 million transfer project. Looking ahead, 54% of non-users planned to adopt this infrastructure within a year. By February 2026, the actual annual payment volume using consumer stablecoins was expected to reach around $390 billion, twice that of 2024, with about 60% being B2B transactions. The Hyundai Card completed a cross-border corporate payment in just 7 minutes. Visa’s annual settlement volume across nine stablecoin chains reached $7 billion, a 50% increase in one quarter. These are not marginal experiments; companies are using stablecoins to address technical issues such as slow cross-border settlements and trapped funds.

Collateral management represents the largest yet least mentioned application of tokenization. Kinexys, part of JPMorgan, processes around $5 billion in transactions daily, with a cumulative settlement volume of $30 trillion, including over $1.75 trillion in intra-day buyback transactions. BlackRock has used tokenized money market funds as derivatives collateral at Barclays. Bodry processes $354 billion in transactions daily. CME is collaborating with Google Cloud to build a similar system, aiming to create a collateral market worth $15 trillion.

Collateral is crucial for hedge funds holding positions they do not want to sell but wish to use for borrowing. Due to mutual distrust, collateral is placed in custody with a third-party agent, involving multiple hands and accumulating costs. Semi-liquid assets maintain security while changing usage conditions, allowing borrowers to freeze collateral or adjust spending. Like Kinexys, its valuation also reaches $15 trillion. The logistics of transferring collateral have disappeared with software, leaving only human judgments related to assessing asset values and making default decisions late at night.

The failure of several blockchain trade finance networks highlights the limitations of technology without proper risk assessment. Between 2018 and 2020, companies including HSBC, Maersk, and BNP Paribas launched four blockchain networks for trade financing, but none survived beyond 2023. In June 2022, we.trade went bankrupt. In November 2022, Maersk and IBM shut down TradeLens. Early in 2023, Marco Polo Restaurants closed down, owing $4.6 million. In November 2023, Contour closed after processing only 60 to 70 transactions per month on average, later acquired by XDC Network.

Faster electronic letters of credit improved document processing speed without affecting the core costs of credit underwriting. Komgo is the only survivor among these companies. It survived because it abandoned blockchain technology. Launched by several large banks in 2018, Komgo initially offered digital letters of credit and document workflow tools. The letter of credit product failed, but the paper document product continued to operate. While competitors collapsed trying to digitize trust, Komgo survived by focusing on its mechanical pipeline business.

Tether demonstrates the profitability of acting as a mechanical pipeline, accepting dollars, holding Treasury bonds, and issuing tokens, while actual customer transactions are handled by exchanges, thus eliminating operational costs associated with human trust. This fully automated asset transfer model allowed a team of 300 people to generate $10.09 billion in profits in 2025. Tether’s average employee income was as high as $33.6 million, far exceeding that of traditional risk-management banks like JPMorgan and Goldman Sachs. Later, the company expanded into lending.

Its secured loans increased from $14.6 billion on September 30 to $17.04 billion by December 31, an increase of nearly $7 billion in six months. Although borrower identities remain confidential, these loans are protected by a safety net of $6.34 billion. When Tether started lending for the second time, it had to hire staff to assess collateral and collect margin late at night. Two factors significantly distorted Tether’s profitability: nearly half of its profits came from the surge in prices of its huge gold and Bitcoin reserves, and the tokens it issued, worth billions of dollars, did not require any interest payments.

Circle showed a similar pattern. The company estimated that distribution costs related to Coinbase in 2025 would reach $1.4 billion, up from $924.5 million previously. This meant that 51% of its $2.7 billion in revenue flowed to Coinbase, a company that neither issues USDC nor manages reserves. Coinbase is responsible for user registration, KYC processes, and anti-fraud teams. Verifying customer identities still requires human judgment. Circle reduced its workforce by fully outsourcing this process, turning internal salary expenses into external contract costs.

Enterprise blockchain and stablecoin technologies solve three major operational challenges: automated flow of cash, collateral, and documents; release of idle funds trapped in payroll fluctuations and custodial accounts; and elimination of cross-border friction in Latin America, Africa, and Southeast Asia. This drives the 10% cost reduction reported by executives. Corporate bond issuance is hardly attracting attention. Germany’s eWpG project enabled Siemens to issue bonds successfully.

As of June 2024, the total value of eWpG digital securities issued was around €236 million, with KfW issuing €150 million through two transactions. But this has had no impact on the prosperity of Europe’s corporate bond market. In the past, finance directors profited from delayed settlements. After floating interest rates disappeared, they turned to managing pre-funded accounts. Today, tokenization has completely changed this landscape, marking the end of float profits and the beginning of automated efficiency.
