Abstract: This week, I was learning some APIs related to Telegram Bot. The framework of the TON contract has been basically completed. I was a little happy, but the plunge of the entire crypto market on Monday really cast a shadow on my mood. I had certain expectations for this result. But I didn't expect it to come so quickly and so violently. Therefore, I sorted out some of my own views and shared them with you. I hope you can stabilize your mentality and don't let panic affect your investment decisions. In general, the core reason for the sharp pullback of risky assets led by US technology stocks in this round is that the Bank of Japan's aggressive interest rate hikes have made many JPY carry trades (JPY Carry Trade) paths invalid or face greater risks, specifically in three aspects: exchange rate fluctuations, interest rate reversals and liquidity risks. In the face of these risks, "Mrs. Watanabe" are closing their positions to repay yen debts and reduce risks.

Abenomics and Japan's long-term negative interest rate environment have made the yen an important global financing and carry asset

I believe that those who have a basic understanding of economics are familiar with the so-called "Lost Twenty Years of Japan". After the bursting of Japan's bubble economy in the early 1990s, the economy fell into a long period of stagnation and entered the so-called "Lost Twenty Years". During this period, economic growth was slow, and the investment willingness of enterprises and individuals was sluggish, leading to continued deflation. In response to the economic downturn, the Bank of Japan began to implement a low interest rate policy in the late 1990s, lowering the benchmark interest rate to near zero, hoping to stimulate economic activity by reducing borrowing costs. As the effectiveness of traditional monetary policy tools weakens,

It is against this background that the general term for a series of economic policies introduced by former Japanese Prime Minister Shinzo Abe after he took office for the second time in 2012. The core goal of these policies is to stimulate economic growth, end long-term deflation and solve the structural problems of the Japanese economy. The core framework of Abenomics consists of the "three arrows". Here I will only briefly introduce its bold monetary policy, which mainly includes two aspects: First, the Bank of Japan has implemented a large-scale quantitative easing policy. This means that the Bank of Japan injects a large amount of funds into the market by purchasing government bonds and other assets to lower interest rates and increase liquidity. The second is that the Bank of Japan officially introduced a negative interest rate policy in 2016. This policy intends to further reduce the cost of interbank borrowing and encourage more funds to flow into the real economy, thereby promoting consumption and investment and raising inflation expectations. The so-called "negative interest rate" is mentioned here. It does not mean that the lender of funds needs to pay interest to the borrower, but that the real interest rate is negative, that is, the interest rate is lower than the domestic inflation rate.

In this context, a type of carry trade has gradually become popular, namely the JPY carry trade. The market has given a very interesting name to traders who do this carry trade, called "Mrs. Watanabe".

Refers to an investment strategy based on interest rate differentials. Its basic principle is to borrow money in a low-interest currency (such as the Japanese yen), and then invest the funds in a high-interest currency or high-yield asset to earn the interest rate differential. The operating principle is as follows:

Borrowing Yen: Since interest rates in Japan are very low (sometimes close to zero), investors can borrow Yen very cheaply.

l Convert to a higher-yield currency: Convert the borrowed Japanese yen into another currency with a higher interest rate, such as the Australian or New Zealand dollar.

Invest in high-yield assets: Then invest the funds in bonds, deposits or other assets of the country with the high-yield currency to earn higher interest income.

l Interest rate spread income: Investors' profits come from the spread between borrowing costs (low-interest yen loans) and investment returns (high-interest assets).

In fact, this kind of interest rate arbitrage transaction is also widely distributed in the DeFi field. The most typical one is the LSD-ETH interest rate arbitrage, that is, using stETH as collateral in lending platforms such as Compound, lending ETH, and then exchanging it for stETH again. If the borrowing rate of ETH is lower than the yield of stETH during the whole process, there is room for interest rate arbitrage. The same is true in the yen arbitrage market. Usually there are two operation paths: the first is to use US dollar assets as collateral, borrow yen, and directly purchase high-dividend stocks of the five major Japanese trading companies. This is actually one of Buffett's core investment portfolios in recent years. The second is to borrow yen and sell it again for US dollars, and then purchase some high-interest financial instruments, such as US stocks and US bonds. This is similar to the revolving loan gameplay in DeFi just introduced.

This kind of transaction has become extremely popular as the United States officially entered the interest rate hike cycle in 2022. Therefore, with the Fed's interest rate hike, major economies around the world have entered the interest rate hike cycle in order to stabilize exchange rates and avoid capital outflows. Among them, only Japan still adheres to its low interest rate policy, which makes the yen the main source of low-cost financing in the tightening cycle. Of course, some friends will say that the RMB interest rate is also very low, but considering the overall international political background and the dividends of China's financial sovereignty, the RMB is not suitable as an carry asset. Therefore, it can be said that in this round of tightening cycle, the reason why the US "Seven Sisters of Technology" market is still "the horse is still running and the dance is still dancing" is inseparable from the support of the yen.

This has had both positive and negative effects on Japan. On the positive side, due to the existence of the "Buffett carry path", Japanese stocks have experienced a long-term growth. This has brought about a rare "wealth effect" in Japan. We know that the vitality of an economy is mainly built on the wealth effect. Only when people can obtain wealth relatively easily and remain optimistic about future returns will they dare to increase leverage investment or consumption. Only in this way can economic vitality be created. Japan, driven by foreign capital, has set off a surge in the "Japanese Special Estimates". The wealth effect brought about by this has officially turned Japan from long-term deflation to moderate inflation, which can also be said to have realized the original idea of ​​Abenomics.

But on the other hand, due to the existence of another carry trade path, a large amount of yen has been converted into US dollars to purchase US dollar assets, which has caused the yen to enter a long-term depreciation trend against the US dollar. From 2021 to 2024, the US dollar to yen price has risen from a low of 103 to 160, and the yen has depreciated by more than 60%. However, considering that the fluctuation of the currency exchange rate does not actually have such a strong impact on the sense of gain of the country's citizens, even under such depreciation, Japan's domestic inflation is also growing in an orderly manner.

The confrontation between the Bank of Japan's forward-looking guidance and the speculative market has officially come to an end recently, and the yen has ushered in a V-shaped reversal

After the whole trend lasted for more than two years, it has recently reversed, which is naturally due to the end of the US dollar interest rate hike cycle. At the beginning of 2024, the newly appointed Bank of Japan Governor Kazuo Ueda reversed the negative interest rate policy of the previous governor Haruhiko Kuroda and began to give the market forward-looking guidance on interest rate hikes. However, the market does not seem to believe it, but chooses to go against the Bank of Japan. The impact brought about by this is that the yen has depreciated all the way below 160 in the first half of this year. One interpretation of the reason behind this is that the speculative market does not recognize the sustainability of Japan's inflation, and believes that after the United States enters a cycle of interest rate cuts, Japan will return to its old deflation. Another interpretation is that it comes from the hedging demand in a complex yen interest rate arbitrage path. The core of this interest rate arbitrage path is Nvidia. Simply put, chip stocks such as Japanese electronics have a strong correlation with Taiwan Semiconductor and Nvidia in stock prices. This is related to the political and industrial transfer background. Therefore, for a long time, buying Japanese chip stocks is an important channel to capture the alpha returns of the AI ​​track. However, entering 2024, the US stock market has a clear "shrinking circle" trend. Capital gathers at the head for risk aversion, especially Nvidia, which makes Japanese chip stocks gradually decoupled from Nvidia. In order to avoid selling Japanese electronic stocks and losing future alpha returns, many funds have a hedging demand, so selling the yen and buying Nvidia has become a good choice. This view is excerpted from Fu Peng, an economist I like very much. If you are interested, you can go to his official account to read this part of the logic.

But no matter what the reason, this confrontation ended last Wednesday when the Bank of Japan officially raised interest rates by 15 basis points, far exceeding market expectations. The market has officially reversed. First, it can be seen that the exchange rate between the US dollar and the Japanese yen has quickly risen from 160 to 143 as of the time of writing. At this point, the Japanese yen carry trade has officially come to an end, and a large number of traders have begun to close their positions. This has led to a large number of risky assets denominated in US dollars being sold, and then exchanged for Japanese yen to repay debts.

So we can see that after the weekend, when the market fully digested the news of Japan's interest rate hike, the entire liquidation officially entered a climax. This is the source of the plunge in crypto assets on August 5. There is also evidence that can explain this problem. In this round of decline, the decline of income assets is much higher than that of zero-interest assets such as Bitcoin, especially ETH. Because they are the core objects of interest rate arbitrage.

The Bank of Japan is a cooperating party in the US-Japan alliance, and the dollar is the real factor that determines the future trend.

Here I hope to briefly look forward to the future trend. I still hope that everyone will not be scared by this retracement, because although the scale of the yen carry trade is not small, I think that in the US-Japan alliance, Japan is actually still a cooperative party. The reason why the interest rate hike was announced recently is just to match the US monetary policy. We know that the reason why the United States did not enter a recession early and the reason why the Federal Reserve has been slow to cut interest rates is the active US stock market. Even though small and medium-sized enterprises are already wailing everywhere, due to the wealth effect brought by the seven sisters of technology, especially Nvidia, the US GDP driven by the financial sector has not shown a significant decline. If the United States rashly cuts interest rates, it will greatly stimulate the risk market, which is very likely to cause inflation to reignite, which is obviously unacceptable. However, referring to the current economic situation in the United States, the United States has to cut interest rates again, so it is necessary to find a reason for the Federal Reserve to cut interest rates, and this reason is actually the retracement of the US stock market. In order to cooperate with this policy, it is not difficult to understand the Bank of Japan's move. So when the United States officially enters the interest rate cut cycle, with the easing of liquidity again, crypto assets will surely usher in a recovery again. Therefore, everyone should remain patient and optimistic about the future. Of course, for those with high leverage, appropriately reducing the leverage ratio is also an option they have to face.
