Currency strength plays a vital role in measuring a country's dominance in the global economy as well as in international politics due to its global value in international trade.

Currency Strength - What is it?

When a national Currency is traded against other currencies or for products, its strength measures its relative purchasing power. An exchange rate is calculated based on the quantity of goods and services purchased and the amount of foreign currency received in exchange for one national currency unit.

When a currency's economic value increases, its spenders can purchase more products, while its earners will benefit from more valuable income.

The strength of a currency is determined by a combination of local and international factors, including demand and supply, inflation and economic growth in the country, and the. Three dimensions can be used to evaluate the Currency Strength if all factors are taken into account:

Purchasing power: the relative purchasing power of goods and services against foreign currencies

Utility is relevant as a financial valuation and exchange device in foreign economies.

Foreign countries hold foreign reserves because of their acceptability in international trade.

Increased purchasing power promotes spending. A surge in supply and demand stimulates imports and exports, resulting in a flourishing of international trade.

As a result, the national currency gains utility in trade partner countries, which, in turn, drives their central banks to create reserves for it. This allows direct currency exchange without the use of a stronger currency like the U.S. dollar as a mediator.

As a result, national currencies strengthen in the money markets and gain value in Forex pairs when a trading partner's currency value fluctuates.

As the world's largest consumer market and the primary trade and reserve currency, the U.S. Dollar is currently considered the strongest currency.

In a crisis, everyone looks to the U.S. dollar for a place of safety. Around 60% of central bank reserves, 40% of debt, 90% of international trade, and 80% of global trade are denominated in dollars. The strength of the dollar increases default risk for countries and foreign companies that borrow in the U.S. dollar but earn revenue or taxes in their domestic currencies.

What is the formula for calculating currency strength?

When buying locally produced goods and services, the strength of the national currency is calculated as the purchasing power. This reveals the nominal income of the citizens.

Real income represents the true economic value of the income amount in pre-inflationary conditions and is calculated by adjusting the nominal income value to the observed period.

The USD Index compares the strength of the American Dollar against the currencies of the major trading partners of the U.S. It calculates a weighted average price of the USD currency pairs with the Euro, British Pound, Japanese Yen, Canadian Dollar, Swedish Krona, and Swiss Franc. With a weight of 57%, the Euro is the Dixie's strongest currency, while the Swiss Franc has a weight of only 3.7%.

Economic Indicators based on currency strength

A country's currency strength can impact its domestic economy and international trade activities in various ways. Depending on economic conditions as well as ., a strengthening or weakening currency value might have different implications as a lagging indicator.

Economy at home

When the economy is stagnant, the central bank can cut interest rates to reduce currency strength to reduce its purchasing power over locally produced goods and services.

When borrowing costs are reduced, production accelerates, resulting in national growth. The increased income and wages of the citizens result in an increase in spending and consumer demand, which in turn leads to inflation of consumer prices and higher corporate profits for the businesses. The strength of the currency increases organically when the domestic economy is stimulated by expansionary measures.

If the currency keeps strengthening, the cost of living will rise above affordable levels, and the companies will not be able to maintain profitability with high wages and expansion costs.

With layoffs beginning, the economy will have stagflation with high inflation and unemployment. The central bank will prevent this by increasing interest rates to slow down the economy.

Trade internationally

As the currency strength increases, importers will be able to purchase larger quantities with the same nominal amount or the same quantity with less nominal amount. Furthermore, the real value of the currency strength will increase the exporters' nominal income, but the country's economic policy determines the currency's effectiveness.

Take, for instance, a nation that implements export-led growth, such as China. They would prioritize a weak currency value to keep their domestically made goods and services affordable and draw in foreign purchasers. Their exports will be bolstered by having a comparatively weaker currency, allowing the Chinese economy to thrive through the inflow of foreign currencies. Conversely, countries pursuing import-led growth, like the U.S., value a strong currency value to improve their buying power and facilitate large-scale imports of products.
