Background of Silicon Valley Bank

Founded in 1983, SVB grew into the 16th largest bank in the U.S., with assets exceeding $209 billion by the end of 2022. It specialized in serving technology startups, venture capital (VC) firms, and innovation-driven companies. SVB’s business model relied heavily on deposit funding from these clients and investments in long-duration U.S. government bonds.

Credit Suisse, one of Switzerland’s most prestigious banks, fell from grace due to years of scandals, mismanagement, and financial instability. Once a symbol of Swiss banking excellence, the bank collapsed in 2023, forcing a historic takeover by UBS. This case study explores the major factors leading to Credit Suisse’s downfall, examining key financial data, regulatory failures, and market reactions.

Background of Credit Suisse

• Founded: 1856
• Headquarters: Zurich, Switzerland
• Peak Market Capitalization: ~$96 billion (2007)
• Core Services: Investment banking, wealth management, asset management

Credit Suisse was once among the most respected global banks, competing with giants like JPMorgan Chase, Goldman Sachs, and Deutsche Bank. However, a series of financial missteps and scandals weakened its standing in the banking industry.

Prologue: The Illusion of Prosperity

In the early 2000s, the United States and much of the Western world were riding high on a wave of economic prosperity. The stock market was booming, home prices were soaring, and credit was available to almost anyone who wanted it. The American Dream had never seemed more attainable. But beneath the surface, cracks were forming in the foundations of this seemingly unstoppable growth.

Act 1: The Bubble Inflates (2000-2006)

The origins of the Great Recession can be traced back to a combination of financial deregulation, a booming housing market, and risky lending practices.

• The Role of Subprime Mortgages:
  • Banks and financial institutions, encouraged by deregulation, began issuing high-risk loans to borrowers with poor credit histories.
  • The subprime mortgage market grew from 8% of total mortgage originations in 2001 to over 20% by 2006.
  • Mortgage-backed securities (MBS) and collateralized debt obligations (CDOs) turned these risky loans into attractive investments.

• The Role of the Federal Reserve:
  • In response to the dot-com bubble burst in 2000, the Federal Reserve lowered interest rates from 6.5% in 2000 to 1% by 2003.
  • Cheap credit fueled an artificial boom in housing, encouraging speculative investments.

• Wall Street’s Greed and Financial Engineering:
  • Major banks and financial institutions, including Lehman Brothers, Bear Stearns, and AIG, aggressively pushed for the sale of MBS and CDOs.
  • Credit rating agencies, such as Moody’s and Standard & Poor’s, assigned AAA ratings to these risky securities, falsely signaling their safety to investors.

In the bustling streets of Glasgow, Scotland, in the 1870s, a young, ambitious entrepreneur named Sir Thomas Lipton had a vision—to make tea, once a luxury for the elite, accessible to everyone. Little did he know that his dream would evolve into a global tea empire that would redefine the industry for generations to come.

The Humble Beginnings

Thomas Lipton, born in 1848 to Irish immigrant parents, was no stranger to hard work. At the age of 15, he sailed to the United States, where he took up various jobs, including working in a grocery store. Observing the efficiency of American retail operations, he returned to Scotland with a dream of revolutionizing the food trade.

In 1871, at the age of 23, Lipton opened his first grocery store in Glasgow. He marketed his store as offering “the best goods at the cheapest prices,” a philosophy that won the hearts of working-class families. His business grew rapidly, and by the 1880s, he owned over 300 stores across Britain. But Lipton was always thinking bigger.

Introduction to Explainable AI (XAI)

Explainable AI (XAI) refers to the subset of artificial intelligence focused on making the decisions and predictions of AI models understandable and interpretable to humans. As AI systems grow in complexity, particularly with the use of deep learning, their “black-box” nature poses challenges in trust, accountability, and regulatory compliance. XAI techniques aim to bridge this gap by providing insights into how AI models make decisions.

Key Components of XAI

Model Interpretability:

• Ability to understand the inner workings of an AI model.
• Examples: Decision trees, linear regression, and simple neural networks are inherently interpretable.

Post-Hoc Explanations:

• Techniques that explain the decisions of black-box models without altering their architecture.
• Examples: LIME (Local Interpretable Model-Agnostic Explanations), SHAP (SHapley Additive exPlanations).
