Imagine you have two toy cars, let's call them "A Car" and "B Car". You want to make sure that these cars always race at the same speed, so you decide to link them together. This means that whenever one car speeds up or slows down, the other car will do the same.
A linked exchange rate is kind of like this. Instead of toy cars, we're talking about two different currencies, such as the US dollar and the Chinese Yuan. When the exchange rate between the two currencies is linked, it means that they will always be worth a certain amount relative to each other.
So, if the linked exchange rate between the US dollar and the Chinese Yuan is set at 1:7 (meaning that one US dollar is worth seven Chinese Yuan), then regardless of what happens to the value of either currency, the exchange rate will always stay the same.
This can be helpful for countries that want to keep their currency stable and predictable. For example, if a country's currency is linked to the US dollar, it may give investors confidence that the country's economy is stable and not subject to sudden fluctuations in currency value.
However, it can also be risky if a country's economy is struggling and their currency is linked to a stronger currency like the US dollar. If the US dollar gains value, the weaker currency will also need to gain value to maintain the linked exchange rate, which could be difficult if the country's economy is not growing.
Overall, a linked exchange rate is a way of ensuring that two different currencies stay close in value to each other, much like linking two toy cars together to race at the same speed.
