What Is The Japanese Yen Index?

The Japanese Yen index is used to track the overall performance of the JPY by comparing it to a group of other key currencies, such as the USD, EUR, and GBP.

The Japanese Yen Currency Index (JXY) is perhaps the most widely followed Yen index, but there are other indices such as the Dow Jones FXCM Yen Index that traders also follow.

Investors often use the index to make trading decisions by identifying trends in the value of the Japanese Yen and predicting future movements in the currency. The JPY index ultimately provides a benchmark of the performance of Japan’s currency relative to other major currencies.


Japanese Yen indices are calculated against a basket of currencies. The composition and weighting of this basket will depend on the index in question; bear in mind that individual brokers may offer their own take on the Japanese Yen index.

For example, the Dow Jones FXCM Yen Index basket comprises USD, EUR, AUD and NZD, with a market value weighting that is rebalanced each quarter. The international broker FXCM offers its own JPY basket index, comprising AUD, USD, GBP, EUR and CAD with equal weighting.

The weighting at CMC Markets is:

History Of The Japanese Yen Index

The Japanese Yen was historically considered a ‘safe haven’ currency, meaning that during times of economic uncertainty or market volatility, the value of the Yen tends to rise as investors flock to it as a safe place to park their money.

Until the last few years, the Japanese Yen enjoyed a relatively stable exchange rate against the US dollar, fluctuating between a range of 80–120 to 1 USD. During the financial crisis of 2008, the Yen appreciated sharply against the US dollar, reaching a high of around 75 to 1 USD in 2011.

This appreciation was partly due to the safe-haven status of the Yen, as investors sought a secure location to put their capital amidst economic ambiguity.

Some argue that today the Japanese Yen has moved away from this status as import prices have outstripped export prices in Japan and the central bank has kept interest rates low despite high inflation.

In the past two years, the historical Yen rate has fluctuated in a range of 105-125 to 1 USD, due to multiple factors such as the third wave of COVID, the monetary policy of the Bank of Japan, the latest fiscal stimulus package, as well as geopolitical events and market sentiment.

What Factors Influence The Japanese Yen Index?

Traders should consider the multiple factors that affect the price of the Japanese Yen index:

Economic Conditions

The relative strength of the Japanese economy and the economies included in the index, including factors such as GDP growth, inflation, and unemployment, can affect the demand for the Yen.

The same is true for the currencies the Yen index is measured against – if the US economy does poorly (e.g. greater rate of reduction in GDP) in comparison to the Japanese economy, the index value is likely to rise.

Interest Rates

The interest rate set by the Bank of Japan (BOJ) compared to other central banks can affect the demand for the Yen, as higher interest rates make a currency more attractive to investors.

If you can accurately predict the movements of big investors, you can predict the direction the Japanese Yen index will move in.

High interest rates mean more return on investment, and more investment will lead to an increase in the relative value of the Japanese Yen.

Trade Balance

Japan has a large current account surplus, which means the value of its exports is greater than the value of its imports. Current account surpluses mean a strong currency for the country.

Anything decreasing exports or increasing imports (such as geopolitical events) will weaken the Japanese Yen index.
