Citigroup will launch instant cross-border payment services for Japanese companies using blockchain-based tokenized deposits as early as this year. The US bank claims this will be the first such service offered to Japanese clients by a foreign financial institution. The blockchain-based system will enable companies to make foreign-currency transfers instantly, including during nights and holidays when traditional banking systems are unavailable. The service represents an expansion of Citi's blockchain payment capabilities into the Japanese market, offering businesses greater flexibility in managing international transactions outside standard banking hours.
NEOM has secured approximately $3 billion in export credit agency financing from Italy's SACE under a long-term multicurrency untied facility. The deal, NEOM's first corporate ECA financing and the largest untied financing ever guaranteed by SACE, is backed by nine international banks including HSBC, Bank of America, and J.P. Morgan. The financing will support various projects across NEOM, particularly in infrastructure, urban development, construction, and transport. It will enable NEOM to leverage supplies from Italian businesses, especially SMEs. Italian suppliers and contractors have already supported NEOM projects with contracts worth $6.3 billion. The partnership aims to generate capital investment aligned with Saudi Vision 2030 and diversify the Kingdom's economy through foreign investment.
DBS and Citi completed a live cross-border US dollar payment on a Saturday in minutes using tokenized deposits through SWIFT's blockchain-based Digital Ledger. The transaction between DBS in Singapore and Citi's New York office took place on 5 September, whilst conventional transfers can take up to two business days. SWIFT declared its blockchain ledger ready for initial use in July, with 17 banks across six continents preparing live pilots. Participants include Citi, DBS, HSBC, Standard Chartered, UBS, BNY, Wells Fargo, BNP Paribas, and MUFG. Banks issue tokenised representations of deposits on their own ledgers, whilst SWIFT's shared ledger coordinates payment commitments. Final settlement occurs through existing infrastructure. Citi has already processed live transactions with First Abu Dhabi Bank and OCBC.
Citigroup is expected to receive Chinese regulatory approval for its fully owned mainland brokerage as early as this month, Reuters reported. The US bank applied for the licence in late 2021 as part of efforts to deepen its China operations. The bank plans to expand the unit's workforce to around 100 employees by year-end, roughly double current levels, according to sources. Recruitment will cover senior revenue-generating roles and operational positions through relocations and external hiring. The brokerage will seek permission for A-share trading, underwriting, research and principal trading. It aims to leverage Citi's existing mainland corporate relationships for equity and M&A work, focusing on technology, healthcare, consumer and financial sectors. Citi declined to comment on the application.
Anthropic, the developer behind Claude AI chatbot, has secured a $15 billion credit facility ahead of its initial public offering. Major financial institutions including Morgan Stanley, Goldman Sachs, JPMorgan Chase, and Citigroup are backing the arrangement. The facility significantly exceeds last year's $2.5 billion loan and surpasses the company's roughly $10 billion target. Anthropic now expects over $65 billion in annualised revenue, representing more than a sevenfold increase from its pace at the end of last year. Additional banks including Barclays and Bank of America have joined the arrangement. The timing coincides with renewed activity in the US IPO market, positioning Anthropic for a substantial market debut.
