Nasdaq BX, Inc. has proposed a rule change to adjust certain exchange fees based on inflation rates. These fee adjustments, which took effect upon proposal and will become fully operative by January 1, 2025, aim to restore the real value of fees that have remained static over time, eroding in purchasing power due to inflation. The changes will occur in three phases over three years, affecting specific market data products but not all fee categories. The adjustments are calculated using the Data Processing Producer Price Index (PPI) and aim to support the Exchange's ongoing investments in its data products and services.
Simple Explanation
Nasdaq BX wants to change some of their fees, making them a bit higher to keep up with how things get more expensive over time (like when candy costs more than it used to). They're using a special way to decide how much to change the fees, but not everyone is sure if this is the best way.
