Regarding the news of the Federal Reserve's interest rate cut, things have really changed; don't be caught off guard anymore.

The Federal Reserve has issued its strongest and most shocking statement this year - even if inflation decreases, it may not lead to an interest rate cut.

This viewpoint was expressed by Dallas Fed President Lorie Logan, a person of significant weight, whose every public statement stirs Wall Street's nerves.

Logan is a highly influential technical official within the Federal Reserve system, having held several important positions in other departments of the Fed, notably as the head of the monetary policy division at the New York Fed, where she gained deep insights into market microstructure.

Logan is also regarded by Wall Street as the "crisis firefighter"; during the 2008 global financial crisis, her outstanding performance in the New York Fed's market group drew attention.

She truly came into the spotlight during the market crash triggered by the COVID-19 pandemic in 2020 - as the head of open market operations at the New York Fed, she led the design of a series of unconventional liquidity support tools, including corporate bond purchases, with a daily operation scale reaching up to one trillion dollars.

The Federal Reserve previously stated two conditions for resuming rate cuts: a decrease in inflation or a worsening economic situation.

Logan's remarks can be seen as a cold shower for the market, making the prospect of an interest rate cut seem increasingly distant.

The occasion for Logan's remarks was at a banking conference hosted by Southern Methodist University, and it was close to the global market closing time, so it did not attract much attention from the market.

If it had appeared on CNBC's screen, the market would have reacted differently. Logan's original words were: even if we indeed get better data (which seems to be approaching 2%), I believe we should still be cautious.

Because if the labor market and overall economy are strong, even in that environment, it does not necessarily mean there is further room for interest rate cuts. My primary concern is to ensure... that the inflation rate reaches our 2% target.

From her speech, it seems there is no longer a necessity for rate cuts. It is particularly noteworthy that Logan was previously a "dove" official, but has now become "extremely hawkish."

Next week, more Fed officials will speak, and if we hear a few more such voices, then it could really signify a change.
