The term "growing strength" of a currency generally refers to an appreciation in its value relative to other currencies. When a currency is said to be growing stronger, it means that it can buy more of another currency or goods and services in international markets compared to before.
To determine whether a currency is strengthening or weakening, you can observe its exchange rate with other currencies. If the exchange rate of a currency increases, meaning that it takes more units of that currency to buy another currency, then the currency is weakening. Conversely, if the exchange rate decreases, indicating that it takes fewer units of the currency to buy another currency, then it is strengthening.
It's important to note that currency strength can fluctuate due to various factors such as economic conditions, interest rates, political stability, and market sentiment. Therefore, tracking exchange rates and staying updated with financial news and analysis can help in understanding the strength or weakness of a currency.
