Summary
The Legacy Financial System refers to the established financial infrastructure, largely shaped by legislation following the Stock Market Crash of 1929 and enacted in the 1930s and 40s. This system, characterized by its inefficiency and reliance on aging, on-premises technology, is predicted to be superseded by a new paradigm known as Internet Capital Markets. This transformation is driven by advancements in blockchain technology, such as Solana, which can now support internet-scale transactions affordably, and a developing regulatory environment. Key legislative efforts, including the Genius Act for stablecoins and the anticipated Clarity Act, alongside executive actions and the SEC's proactive stance under Chair Paul Atkins, are paving the way for a "digital finance revolution." This shift aims to integrate traditional and digital assets, including tokenized securities and cryptocurrencies, into a single, accessible interface, potentially leading to significant growth in on-chain activity and a fundamental change in how companies are financed, traded, and owned.

View on WikipediaEmergency Economic Stabilization Act of 2008
The Emergency Economic Stabilization Act of 2008, also known as the "bank bailout of 2008" or the "Wall Street bailout", was a United States federal law enacted during the Great Recession, which created federal programs to "bail out" failing financial institutions and banks. The bill was proposed by Treasury Secretary Henry Paulson, passed by the 110th United States Congress, and was signed into law by President George W. Bush. It became law as part of Public Law 110-343 on October 3, 2008. It created the $700 billion Troubled Asset Relief Program (TARP) whose funds would purchase toxic assets from failing banks. The funds were mostly directed to inject capital into banks and other financial institutions as the Treasury continued to review the effectiveness of targeted asset-purchases. The 2008 financial crisis developed partly due to the subprime mortgage crisis, causing the failure or near-failure of major financial institutions like Lehman Brothers and American International Group. Seeking to prevent the collapse of the financial system, Secretary of the Treasury Paulson called for the U.S. government to purchase several hundred billion dollars in distressed assets from financial institutions. His proposal was initially rejected by Congress, but the bankruptcy of Lehman Brothers and lobbying by President Bush ultimately convinced Congress to enact the proposal as part of Public Law 110-343. Early estimates for the bailout's risk cost were as much as $700 billion; however, TARP recovered $441.7 billion from $426.4 billion invested, earning a $15.3 billion profit (an annualized rate of return of 0.6%), which may have been a loss when adjusted for inflation.

- Modernizing Legacy Systems in Banking | Deloitte US
The need for app modernization is accelerated by the growing shortage of legacy talent, which makes it increasingly difficult and expensive for banks to operate and maintain their existing core systems. With core and app modernization, the IT model shifts from in-house, on-premises banking legacy systems to modern cloud-based systems provided by third-party vendors. Banks now have multiple platform options that can enable them to not only modernize their applications but also infuse the new applications and processes with their own business rules through business rules extraction. ● **Focus on business value creation, not just technology replacement.** When modernizing your banking legacy systems and technologies, take advantage of the simultaneous opportunity to improve your business processes and to extract and capture the business rules and institutional knowledge that give you a competitive advantage in the marketplace.

- Just how much of a problem is legacy tech for financial services?
But take apart the tech stack of the average UK financial services company, and you are likely to find a patchwork of poorly integrated technologies and sprawling data feeds. A recent study reported by the Financial Conduct Authority (FCA) showed that 92 per cent of the UK’s financial services companies still relied on legacy technology, and 78 per cent of their data sat in on-premise infrastructure. So, more financial services companies are trying to strategically augment their existing tech stacks to create a flexible, unified data architecture that is capable of supporting artificial intelligence and machine learning projects, and which offers clearer data ownership across the client-facing, risk assessment and administrative departments.
