| From this 2000 article: >The recent rise in margin credit has focused attention on the Federal Reserve’s margin requirements for purchasing equities with borrowed funds, which has been at 50% since 1974. In November and December of 1999, margin credit grew very rapidly, outpacing the sizable appreciation in the overall stock market. And in January 2000, it grew further while the stock market’s valuation dropped, leaving the ratio of margin credit to market capitalization at its highest level in the past 29 years. This Economic Letter discusses the recent trend in margin credit and the merits of using margin requirements as a policy tool. > ... > The Securities Exchange Act of 1934 mandated federal regulation of purchasing securities on margin. The margin requirement was motivated by the concern that credit-financed securities speculation helped fuel the run-up in stock prices prior to the stock market crash of 1929. The act viewed the Federal Reserve as responsible for managing the availability of credit in the economy, so the Fed was charged with setting margin requirements for securities purchases. The Securities Exchange Commission was directed to enforce those regulations. https://www.frbsf.org/economic-research/publications/economi... According to Wikipedia, the rate hasn't been changed since the 1970s: > Regulation T governs the extension of credit by securities brokers and dealers in the United States.[1] Its best-known function is the control of margin requirements for stocks bought on margin. The initial margin requirement for such margin stock purchases has been 50%[2] since 1974,[3] but Regulation T gives the Federal Reserve the authority to change this percentage. Raising the margin requirement ostensibly reduces risk in the financial system by reducing the potential leverage and total buying power of investors. Conversely, lowering the margin requirement increases systemic risk by expanding the buying power and leverage available to investors. Since 1974, the Federal Reserve has not deemed it necessary to adjust the margin requirement despite periodic extremes of price volatility in the equities markets.[4] https://en.wikipedia.org/wiki/Regulation_T Given the absolute neglect of the mandate it was given on this, I suspect the Fed views even mere talk of increasing margin rates as the nuclear option. But if the usual roll call of psyops fail to deliver, this thing is there in its back pocket. I imagine the mere threat would cut 20% off the S&P overnight. |
