Recently, I often have to handle international remittances and foreign exchange transactions at work, and I realized that I still have quite a few gaps in my understanding of currency symbols from different countries. For example, the US dollar symbol has several different ways of writing—sometimes I see $, sometimes US$, sometimes USD, and sometimes I’m not sure exactly how to use them. Later, I understood that although these currency symbols look simple, they are indeed very important in international trade and investment.

Currency symbols are actually image abbreviations used to quickly identify the currencies of different countries. Whether it’s small things like supermarket price tags or big things like trading in the foreign exchange market, these symbols are inseparable. For example, seeing € lets you know it’s the euro, and seeing £ means it’s the British pound. Although the dollar sign $ is used by more than 30 countries worldwide, in the foreign exchange market it usually refers to the US dollar. Using these symbols correctly helps us quickly recognize currency values and price movement trends, saving us from a lot of tedious writing.

I compiled a table of commonly used currency symbols: the US dollar (USD) is $, the euro (EUR) is €, the British pound (GBP) is £, the Japanese yen (JPY) is ¥, and the Chinese yuan (CNY) is also ¥ (these two are easy to mix up). The Hong Kong dollar (HKD) is HK$, the New Taiwan dollar (TWD) is NT$, and the Australian dollar (AUD) is A$. In Asia, there are also the Korean won (KRW) (₩), the Thai baht (THB) (฿), the Indian rupee (INR) (₹), and so on.

On a keyboard, entering these symbols actually has shortcut keys. For example, on Mac, the US dollar symbol is directly Shift+4, and on Windows it’s also Shift+4. On Mac, the euro symbol is Shift+Option+2, and on Windows it’s Alt+E. On Mac, the British pound is Option+3, and on Windows it’s Alt+L. The yen symbol on Mac is Option+Y. Mastering these shortcuts can truly improve work efficiency.

Also, pay attention to the fact that some symbols are easy to confuse. The ￥ symbol represents both the Chinese yuan and the Japanese yen; the way to tell them apart is to add the currency code in front—for example, CNY￥100 means 100 yuan of the Chinese yuan, while JPY￥100 means 100 yen of the Japanese yen. The $ symbol is even more universal, so when you see it, you should check whether there is a letter label in front, such as US$, NT$, HK$, A$, and so on. Another interesting one is that the ฿ symbol means the Thai baht in foreign exchange, but in cryptocurrency it stands for Bitcoin.

In foreign exchange trading, you also often see currency pair notations like EUR/USD and GBP/JPY. This is not a single currency symbol, but the exchange rate between two currencies. The one in front is called the base currency, and the one in the back is called the quote currency. For example, USD/GBP means how many British pounds are equal to 1 US dollar. This currency pair format is at the core of forex market trading—investors seek returns by buying and selling currency pairs.

Overall, whether you’re doing international trade or investing in foreign exchange, it really is necessary to master the correct usage of each country’s currency symbols and the US dollar symbol. These seemingly simple symbols actually represent important information within the global economic system.
