First of all, the operation of international hot money has injected new trading ideas into financial markets. From the thrilling battle for Hong Kong dollars, you may appreciate the style of international speculative capital's all-round attack and cross-attack strategy. International hot money can often observe the financial market as a whole, understand the changes and mutual influence of each sub-market one by one, and then form a systematic project of capital investment in order to follow suit. This is different from the usual practice of ordinary investors to absorb on dips and distribute at high points. For example, in order to disrupt Hong Kong's financial market and reap huge profits, Soros first sold a large number of Hong Kong dollars in the foreign exchange market and absorbed US dollars. Because they expect that in order to maintain the stability of the linked exchange rate system, the Hong Kong Monetary Authority will definitely raise the interest rate of Hong Kong dollar deposits. However, the market interest rate changes inversely with the securities price, and the rise of interest rate will inevitably lead to the decline of securities price and stock index. At this time, the establishment of short positions in stock index futures can seek benefits. Therefore, when they sell Hong Kong dollars in the foreign exchange market, they also sell a lot of Hang Seng Index futures. This mode of operation is obviously different from the unilateral operation we are used to. Although this well-prepared financial war ended in Soros's fiasco, this comprehensive consideration and overall investment operation is undoubtedly a new investment concept, which is conducive to promoting the integrated development of financial markets.

Second, the violent flow of international hot money has enlivened the transactions in the international financial market. Because without its existence and function, the whole financial market will become very dull and boring. Market transactions are decided by the supply and demand sides, and the absence of either side will lead to the stagnation of transactions. Therefore, the existence of active speculative capital has created an active atmosphere for the market and promoted the smooth completion of the transaction.

Third, a large number of international hot money transactions have promoted the prosperity of financial derivatives. When defining international hot money, we say that its main battlefield is the financial derivative commodity market. Because financial derivatives trading has the characteristics of high risk and high return, this is consistent with the investment preference of international hot money. We are familiar with treasury bonds futures and stock index futures, which are both financial derivatives and the favorite investment targets of international hot money. It should be said that the emergence of financial derivatives is to serve investors' value preservation. However, without the existence of speculative capital, the financial derivatives market would not be as active as it is today, and its positive role in balancing exchange rate fluctuations and interest rate fluctuations would not be so significant.

Fourth, the growing international hot money requires the international financial system to make corresponding reforms. The flow of international hot money is a purely market-oriented behavior. After decades of development, its financing scale has been expanding, and its influence on international finance is increasing.
