On September 9, U.S. stocks began repurchasing Treasury bonds, raising the per-operation repurchase limit from $2 billion to $4 billion, effective through November 4.

Recently, the 10-year Treasury yield has been around 4.79%–4.81%, while the 30-year yield has been around 5.27%–5.28%, close to or back at pre-announcement levels.
This scale remains relatively small compared with the entire Treasury market, worth over $40 trillion, and quarterly new issuance of long-term Treasuries. Under the original plan, the long-term repurchase limit from September 9 to November 4 was approximately $14 billion; after doubling, an additional approximately $14 billion was added.
The increased repurchases on September 9 provide marginal support and improved liquidity for long-term U.S. Treasuries, potentially easing upward pressure on yields in the short term and benefiting risk assets and gold. However, I personally think they have an impact on the current market, but not a significant one.
The more times like this, the more important it is to stay calm. Rising crude oil prices and falling U.S. stocks, gold, and crypto do not mean funds are fleeing; rather, they indicate a shift toward a more prudent approach and risk aversion. This can be seen in the crypto market, where various altcoins remain highly volatile while also driving ecosystem growth.
Therefore, I think shorting is fine, but it must be short-term shorting. Trying to capture a drop of several thousand or even over ten thousand dollars in one go is very difficult in the current market. Repeated shakeouts will definitely drive you out.
