It seems like you are asking about factors that influence the value of a currency. In this context, the most relevant concept would be Exchange Rates.
To elaborate:
- Exchange Rates: This refers to the value of one currency in relation to another. Exchange rates are determined by various factors, including supply and demand for the currencies in the foreign exchange market, economic indicators, interest rates, inflation, and geopolitical stability.
While Trade Rates and Tariffs can influence the overall trade balance and economic conditions that impact currency values, they are not direct measures of how a currency is valued against others.
