Not trying to be a hero, but a lot of information and explanation on the economy and stock markets in CFC are misplaced just like this picture:
The US government debt ceiling is a problem and is not a problem. It will eventually get over it for sure after a few days, weeks, or even months, just like every time it came before.
1) The US government debt is a problem! Because since the pandemic the government debt has explosively increased ( debt/GDP,124% to 31T). Someone in this post said: " 实际上米国国债占财政收入的比例处于历史低位." That is untrue. Check out the diagrams below to compare US government revenue to government debt( national debt):
Federal Revenue Trends over time FY 2015 -2022:
US national debt over 100 years
For details above click the links to see the Stackline diagrams. Brief calculation on it from the two Stackline diagrams above is as follows:
2006: Debt: $12.40 T, Revenue: $4.02 T, Debt/Revenue: 309%;
2022: Debt: $30.93T, Revenue: $4.90 T, Debt/Revenue: 631%
2) The US government debt is not a problem! Think about the history of every time the US government debt ceiling ( crisis): the last time the US government debt ceiling crisis was in 2011, among five rating agencies, only moody cut the US government rating from AAA to AA+. As a result, both Moody and the US government were embarrassed: the government rating was cut due to debt and money print; Moody was embarrassed because its calculation has an error ( missed $1 billion or trillion?).
The media reports on the US government debt ceiling crisis and the US government's probable default on its debt were fierce at the time. The market reaction was that people rushed into buying the US government treasuries (debt) and US$ went up. ( rush to buy a possibly defaulted debt?

)
Fed chair Allen Greenspan, who just retired not long ago at the time, spoke the truth in NBC" Meet the Press":
"The United States can pay any debt it has because we can always print money to do that"
3) You may ask why? These pictures briefly explain it:
In the case of a stock market master in CFC recommended buying" 国防ETF: ITA (到处都在军备和打仗,国防类的会很稳健) and to avoid misperception from the above pictures I posted, for those who might be impulsive to buy defense stocks, be careful what you wish for! Defense stocks are expensive right now, and the debt ceiling issue won't help the defense stock. To buy defense stock from the above pictures or from some stock master's advice in CFC is completely at your own peril.
