UBX Tanzania deepens partnership with ACI Worldwide to power the next phase of the nation's digital economy. The upgraded platform is expected to double monthly payment transaction processing capacity ACI Worldwide (NASDAQ: ACIW), an original innovator in global payments technology, today announced the extension of its long-standing partnership with UBX Tanzania Limited, Tanzania's leading national payment service provider. The extended partnership marks a significant milestone in a relationship that spans nearly two decades and is focused on strengthening infrastructure resilience, enhancing scalability and enabling innovation to support Tanzania's rapidly evolving digital economy. UBX currently powers the core payments infrastructure for 18 banks in Tanzania, supporting a nationwide network of over 250 ATMs and processing more than 1.3 million transactions monthly. Through this extended collaboration, UBX is positioned to accelerate the onboarding of new financial institutions and is projected to nearly double its payment-processing capacity over the next five years. Built on an active, high-availability infrastructure across two certified PCI-compliant data centers in Tanzania, the platform strengthens resilience and reduces service disruption and operational risk. "As Tanzania's payments landscape continues to grow in scale and complexity, we need infrastructure that is not only reliable but also adaptable to future demands," said Seronga Wangwe, Managing Director and Chief Executive Officer of UBX Tanzania Limited. "ACI gives us the confidence to expand our services, support more institutions, and continue delivering secure, high-performance, and always-on payment experiences that underpin economic activity across the country." Under the extended partnership, UBX can now serve merchants directly, expanding its market reach and service portfolio while streamlining operations and delivering significant savings in cost, time, and effort. The platform also enables UBX to launch new value-added services, such as digital wallets, supporting innovation across Tanzania's growing fintech ecosystem. Designed to meet global and local regulatory standards, the platform secures transactions and helps UBX navigate evolving regulatory complexity without the burden of infrastructure management. "Our extended partnership with UBX reflects a long-standing relationship grounded in decades of mutual trust, underpinned by ACI's deep global expertise in the payments industry and a shared commitment to advancing digital payment transformation in Tanzania," said Nick Craig, General Manager, EMEA at ACI Worldwide. "ACI is proud to support UBX's vision in the development of an inclusive, sustainable, and innovative payments ecosystem that promotes financial inclusion and drives long-term economic growth."
Why one banking systems engineer thinks XRP price could hit $300 after clarity act passes. The post why one banking systems engineer thinks XRP price could hit $300 after clarity act passes appeared first on coinpedia fintech news. Banking systems engineer CharuSan has outlined a case for XRP reaching $300 that rests not on speculation but on how banking infrastructure actually works at scale. The argument challenges a widely held assumption. Most XRP price forecasts model adoption as a slow process where Ripple signs individual contracts with thousands of banks one by one. CharuSan says that misunderstands how modern banking software is deployed. Ripple has already partnered with major financial infrastructure providers including Volante, ACI Worldwide, and Finastra. These companies do not serve one bank at a time. They serve thousands of banks simultaneously through centralised cloud systems. A single software update from any one of these providers can make XRP liquidity available to every bank connected to their network overnight. "Ripple does not need to sign individual contracts with 13,000 banks," CharuSan wrote. "The moment they plug into the central cloud, all banks connected to the system become capable of using XRP liquidity." The price logic. On valuation, CharuSan made a structural argument rather than a speculative one. If XRP remains at $10 to $20, the total liquidity pool it can provide is too small to handle the volume of global cross-border payments that banks process daily. He compared it to trying to move ocean water through a small straw. As adoption scales and transaction demand increases, a higher token price is not just a side effect. It is a requirement. Larger payment flows need deeper liquidity pools, and deeper liquidity pools require a higher token price to function efficiently. The counterargument. Critics say that $300 would place XRP's market cap in territory that would require extraordinary capital inflows. Most long-term price models top out between $30 and $100.
Colombia's Bre-B hits more than 500 million transactions as ACI Worldwide and Banco de la República take the stage at Fintech Americas 2026. WHY THIS MATTERS: Colombia's Bre-B system is a new benchmark for real-time payments in Latin America, establishing a critical foundation for greater financial inclusion across the region. Processing half a billion transactions and registering over 100 million keys in its first five months is a feat of national-scale financial market infrastructure that validates the central bank's approach to public-private collaboration. This adoption rate is not just a statistical milestone; it signifies a massive shift in consumer and business behavior, proving that interoperable instant payment systems - when properly implemented - are immediately sticky. This success offers a direct roadmap for other emerging economies looking to modernize their payment rails and drive transactions away from cash. For global fintechs and financial institutions, Bre-B's trajectory signals that the next competitive frontier in LatAm lies in building services on top of these high-velocity, low-cost rails, particularly as the focus now shifts toward seamless cross-border capabilities. Colombia's real-time payments transformation is accelerating at remarkable speed. In just five months, Bre-B has processed more than 500 million transactions and registered over 100 million payment keys, firmly establishing the scheme as one of the most rapidly scaled real-time payment systems in Latin America. For this achievement, ACI has been named the winner of this year's Central Banking Financial Market Infrastructure Services - Retail Award. The awards judges highlighted the collaborative nature of the scheme, the implementation in record time, and ACI's flexibility in addressing design challenges to deliver the Bre-B implementation on schedule, ensuring a highly successful launch. These milestone results will be in the spotlight at Fintech Americas Miami 2026, where Mauricio Fernández, real-time payments lead, Latin America, ACI Worldwide, and Ana Carolina Ramírez Pineda, deputy director of retail payments, Banco de la República, will share insights into Bre-B's rapid rise and outline what comes next for the national scheme. Powered by ACI Worldwide (NASDAQ: ACIW) and operated by Banco de la República, Bre-B is redefining how Colombians send money, pay merchants, and engage with digital financial services. Its early performance reflects both the scale and inclusivity of Colombia's new real-time payments infrastructure, representing one of the strongest national real-time deployments anywhere in the world. A New Foundation for Colombia's Real-Time Economy Launched to modernize the country's payment infrastructure and expand financial inclusion, Bre-B enables instantaneous, interoperable transfers across all participating financial institutions. Built on ACI's Digital Central Infrastructure, the scheme is already reshaping how consumers, merchants, government entities, and utilities conduct transactions. It also represents a regional first: a nationally coordinated real-time payments scheme jointly developed by the central bank, regulators, commercial banks, and technology partners, setting a new standard for collaborative digital payments innovation in Latin America. ACI Worldwide: Powering Colombia's National Real-Time Scheme As Banco de la República's technology partner, ACI Worldwide provides the addressing directory, 24/7 clearing and settlement engine, and interoperability services that underpin Bre-B's reliability and scale. "Bre-B's first five months demonstrate what coordinated leadership and modern infrastructure can achieve at national scale," said Mauricio Fernández, real-time payments lead, Latin America, ACI Worldwide. "Colombia is now one of the region's most advanced real-time payments markets. We are proud to support Banco de la República in building a system that strengthens financial inclusion and sets a new benchmark for Latin America." "Bre-B has fundamentally transformed how Colombians transact, creating faster, more transparent, and more inclusive financial services," said Ana Carolina Ramírez Pineda, deputy director of retail payments, Banco de la República. "The first five months highlight the power of interoperability and strong public-private collaboration. As we move into the next phase, continued partnership with ACI Worldwide will be essential in expanding innovation and exploring real-time cross-border opportunities." Looking Ahead: Real-Time Cross-Border Opportunities With domestic real-time payments firmly established, attention now turns to the cross-border dimension, particularly the high-volume corridor between the United States and Latin America. At Fintech Americas, ACI Worldwide will outline how domestic real-time schemes like Bre-B can interoperate with global real-time networks, positioning regional banks to compete in the fast-growing remittances and international payments space. Fintech Americas Miami 2026: ACI Worldwide and Banco de la República on Stage Bre-B will take center stage at Fintech Americas as ACI Worldwide and Banco de la República share their journey, insights, and lessons learned. Featured Session: Real-Time Payments and 24/7 Economies, The New Competitive Advantage in Latin America, Wednesday, March 25, 2:30 PM - 3:00 PM EDT * Mauricio Fernández, Real-Time Payments Lead, Latin America, ACI Worldwide * Ana Carolina Ramírez Pineda, Deputy Director of Retail Payments, Banco de la República Together, they will unpack Bre-B's governance model, operational rollout, adoption trajectory, and its wider economic impact. FF NEWS TAKE: The rapid scalability and adoption of Bre-B moves the needle significantly for the entire Latin American payment landscape. It confirms the region's readiness for large-scale real-time payments adoption, setting a high bar for speed and government-led execution. The most important area to watch next is the transition to real-time cross-border payments. Given the high-volume remittance corridor between the US and LatAm, Bre-B's future ability to interoperate with global networks like FedNow or Pix will determine if regional banks can successfully capture a greater share of the international payments and remittances market.
