The SEC is giving money fund boards of directors the discretion whether to impose a liquidity fee if a fund’s weekly liquidity level falls below the required regulatory threshold, and/or to suspend redemptions temporarily, i.e., to "gate" funds, under the same circumstances. These amendments will require all non-government money funds to impose a liquidity fee if the fund’s weekly liquidity level falls below a designated threshold, unless the fund’s board determines that imposing such a fee is not in the best interests of the fund.
Essentially, any cryptocurrency network is based on the absolute consensus of all the participants regarding the legitimacy of balances and transactions. If nodes of the network disagree on a single balance, the system would basically break. However, there are a lot of rules pre-built and programmed into the network that prevents this from happening. From the outset, money market funds fell under the jurisdiction of the SEC as they appeared to be more like investments (most similar to traditional stocks and bonds) vs. deposits and loans (cash and cash equivalents the domain of the bankers). Although money market funds are quite close to and are often accounted for as cash equivalents their main regulator, the SEC, has zero mandate to control the supply of money, limit the overall extension of credit, mitigate against boom and bust cycles, etc. The SEC’s focus remains on adequate disclosure of risk, and honesty and integrity in financial reporting and trading markets. After adequate disclosure, the SEC adopts a hands off, let the buyer beware attitude.
The Money Market enables the commercial banks to use their excess reserves in profitable investment. The main objective of the commercial banks is to earn income from its reserves as well as maintain liquidity to meet the uncertain cash demand of the depositors. In the money market, the excess reserves of the commercial banks are invested in near-money assets (e.g., short-term bills of exchange), which are easily converted into cash. Thus, commercial banks earn profits without sacrificing liquidity.
