árfolyamindex

An árfolyamindex, often translated as exchange rate index or currency index, is a statistical measure that tracks the movement of a particular currency against a basket of other currencies. Instead of comparing a single currency to just one other, it provides a broader perspective on its strength or weakness in the international market.

The basket of currencies used for an árfolyamindex is typically chosen based on economic importance, trade volumes, or monetary policy considerations. For example, the index might include major trading partners' currencies or those that are frequently involved in international transactions with the currency being tracked.

The index is usually assigned a base value on a specific date. As exchange rates fluctuate, the index value changes, indicating whether the currency has appreciated or depreciated relative to the basket. An increase in the index signifies an appreciation, meaning the currency can buy more of the other currencies in the basket. Conversely, a decrease indicates depreciation.

Árfolyamindexek are valuable tools for economists, policymakers, and businesses. They help in understanding the overall competitiveness of a country's exports and imports, assessing inflationary pressures, and guiding monetary policy decisions. For investors, they offer insights into currency trends and potential risks or opportunities. Different organizations and countries may publish their own árfolyamindexek, often with slightly different methodologies and baskets of currencies.
