Summary

The lack of regulation was a significant factor contributing to the Stock Market Crash of 1929. During this period, there was no Securities and Exchange Commission (SEC) to prevent insider trading and market manipulation, which fueled a speculative bubble. This environment, characterized by a complete absence of oversight, allowed for massive expansion of leverage, with banks lending heavily to speculators. The situation is drawn in parallel to modern times, with discussions questioning if the current investment in AI constitutes a similar monetary bubble and where hidden leverage might exist today, such as in the private credit market. The historical context highlights how a lack of regulation, coupled with transformative technologies and a shift in societal attitudes towards debt and wealth accumulation, can create conditions ripe for a market crash, ultimately leading to severe economic downturns like the Great Depression.

Market maker

A market maker or liquidity provider is a company or an individual that quotes both a buy and a sell price in a tradable asset held in inventory, hoping to make a profit on the difference, which is called the bid–ask spread or turn. This stabilizes the market, reducing price variation (volatility) by setting a trading price range for the asset. In U.S. markets, the U.S. Securities and Exchange Commission defines a "market maker" as a firm that stands ready to buy and sell stock on a regular and continuous basis at a publicly quoted price. A Designated Primary Market Maker (DPM) is a specialized market maker approved by an exchange to guarantee a buy or sell position in a particular assigned security, option, or option index.

  • Regulatory Failure - Examples - Understanding Regulation

    The Treasury's own March 2012 'lessons learned' report identified a number of causes of its own and regulators' failure, including serious tensions between the Treasury, the Bank of England and the Financial Services Authority. And financial regulators (the Bank of England and the FSA in the UK) also did not know or did not understand what risks the institutions were taking with the financial instruments or off-balance sheet vehicles, nor did they seem at all concerned that financial deregulation, on both sides of the Atlantic and in Japan, allowed even the regulated banks to lend to a much wider (and riskier) range of borrowers, and failed to recognise the 'moral hazard' associated with such lending.
