SEC draws a hard line on ultra–leveraged stock and crypto ETFs

Rule Changes

The SEC is the main U.S. federal regulator for securities markets, including ETFs and other registered investment companies. It writes and enforces rules such as Rule 18f‑4, reviews ETF registration statements, and has the authority to block or condition new fund launches. - Primary regulator setting and enforcing ETF leverage limits

The letters forced issuers either to withdraw or redesign products that sought ultra‑high leverage just as crypto markets reeled from an October–November crash and heavily leveraged products posted outsized losses.
