1. Liquidity, USD Value and Bitcoin Value
1. Liquidity:
U.S. Treasury bonds are regarded as safe assets around the world and are the cornerstone of the global financial system. Many countries, institutions, and individuals hold large amounts of U.S. Treasury securities. If the United States defaults, it will trigger a crisis of market confidence in U.S. Treasury bonds, which may lead to large-scale selling of U.S. Treasury bonds, thereby triggering a liquidity crisis. The depletion of liquidity will lead to a sharp decline in asset prices (selling assets in exchange for cash flow) and increased financial market volatility, further exacerbating the global financial crisis.
2. USD value:
The U.S. dollar is the world's most important reserve currency. Although the international status of the RMB is rising, the volume of U.S. dollar settlements is still ahead by a large margin. The default of U.S. Treasury bonds will weaken global trust in the U.S. dollar and reduce the value of the U.S. dollar. decline. However, if there is panic in the market and investors sell assets, the demand for the US dollar will increase, and at the same time, another part may flock to other assets considered as "safe havens", such as gold or other strong currencies, which may have a negative impact on the US dollar. The depreciation has a certain buffering effect.

3. Bitcoin value:
The secondary market value of Bitcoin is objectively affected by many factors, including but not limited to: market sentiment, consensus, popularity of the BRC standard, attitudes of governments in different countries, regulatory policies, technological development, application popularity and convenience, etc.
In the event of a U.S. default, Bitcoin could have two distinct reactions.
On the one hand, if investors seek non-traditional (gold, silver) "safe haven" assets, and if the world needs new loose reservoirs to absorb decompression funds, in the medium and long term, the demand for Bitcoin may be different from that of Value may have a relatively positive impact. Multiple discussions on digital assets such as Bitcoin may accelerate among and within countries.
On the other hand, since the value of Bitcoin is highly volatile and risky, if the market panics, investors may withdraw funds from high-risk assets such as Bitcoin, causing the value of Bitcoin to decline. Therefore, Bitcoin's reaction may depend on market sentiment and investor risk appetite.
Personally, I believe that if there is a financial crisis caused by default, there is a high probability that in the short term there will be fluctuations caused by cash flow requirements for survival and company operations, and then new adjustment judgments will be made after the market stabilizes and is relatively calm.
4. Impact on global economy and trade
U.S. debt is considered the safest asset in the world, and the U.S. dollar is the world's main settlement currency. If a default occurs, it may lead to a recession or a deeper economic crisis for the global economy. At the same time, a default on U.S. debt may damage the credit of the U.S. dollar and affect global trade. Countries exporting to the United States may face reduced orders, and countries importing U.S. goods and services may have to pay higher prices. Governments and central banks may take emergency measures, such as interest rate cuts, quantitative easing, etc., to stabilize financial markets and economies.
5. Reshaping the global financial system
A U.S. default could trigger a rethink of the current dollar-based global financial system. Other currencies, especially the yuan, may play a larger and more important role in the global financial system in the future. However, our country is also experiencing the test of real estate and debt. If this crisis can be safely overcome, the internationalization path of the RMB will be further broadened and its position in the settlement system will be further consolidated. In addition, this may accelerate the global exchange of The acceptance of digital currency and blockchain technology may change the global financial landscape.
6. Risk asset value fluctuations
In the event of a U.S. debt default, the value of risky assets (such as stocks, commodities, digital currencies, emerging market assets, etc.) may fluctuate significantly. Risk-averse investors may withdraw funds from these markets, causing prices to fall. Investors looking for high returns may take advantage of this opportunity to enter the market, causing prices to rebound.
2. Theoretically, the following situations may lead to a default on U.S. debt:
Debt ceiling:
The U.S. government's borrowing is controlled by the debt ceiling set by Congress. If Congress fails to raise the cap in time, the U.S. Treasury may not be able to issue more bonds to pay interest and principal on the Treasury securities, which could lead to a default. Moreover, the United States is currently facing the risk of the debt ceiling. It will face the decision-making issue of the debt ceiling around Q3 of 2023. However, in history, although the debt ceiling controversy often caused disputes in Congress, Congress always passed it in time in the end. The bill to raise the debt ceiling avoids a default.
Government shutdown:
If the U.S. government shuts down due to a budget dispute, it could affect the government's debt payments. But even in the event of a government shutdown, the U.S. Treasury can usually find a way to pay its debt. For example, the U.S. Treasury Department may use "exceptional measures," including temporarily halting certain investments or cashing out certain assets, to maintain the government's cash flow and avoid default.
Policy error:
Wrong policy decisions, such as excessive fiscal tightening or excessive monetary tightening, may lead to a recession in the U.S. economy, thereby affecting the government's ability to repay its debt. However, given the U.S. policymaking process and historical experience, the likelihood of this scenario is also quite low. However, given the size and depth of the U.S. economy, as well as the Fed's monetary policy tools, such as quantitative easing, the likelihood of this scenario is also quite low.
3. Extreme black swans, leading to the possibility of default:
External shock:
Extreme external shocks, such as large-scale natural disasters, solar storms that destroy communications, wars, or epidemics, may cause severe damage to the U.S. economy and thus affect the U.S. government's ability to repay its debt. However, in this case, it is still possible for the U.S. government to avoid default by issuing more debt, raising taxes, or cutting spending.
4. Summary
1. Although the possibility of a U.S. default is very small, if it does occur, it will have a major impact on the global financial system. A default on U.S. debt will have a profound impact on global financial markets, economy and trade.
2. When the U.S. government and the Federal Reserve encountered similar problems before, they had a variety of tools they could use to avoid default (such as interest rate cuts, quantitative easing, raising the debt ceiling, etc.). Even amid government shutdowns or debt ceiling disputes, the U.S. government has always found ways to avoid defaulting.
3. The impact of the default of U.S. debt on emerging digital industries such as blockchain may be a situation of rising before rising, because the current consensus is not fully universal. When faced with risks, especially liquidity risks, although BTC had a short-term hedging effect before the banking crisis, when faced with national debt-level risks, more corporate cash flows are involved, and it may be affected in the short term like other risky assets. Liquidity constraints lead to negative trends.
However, in the long run, once interest rates are cut and QE is restarted, or when we calm down and think about new assets representing the future AI and digital era, it will be a brand new opportunity for assets such as Bitcoin. If the settlement currency of the US dollar is affected, some companies and individuals may consider using Bitcoin or other cryptocurrencies for cross-border payments in addition to other legal currencies such as RMB for settlement. If this trend develops, it could drive up demand for Bitcoin while accelerating changes in the way global trade is conducted.
To sum up, I personally believe that if the U.S. debt defaults, it will have a very serious impact on the global economy, but it may be a nirvana effect for emerging fields such as blockchain, Bitcoin, and AI.
