What is Currency Correlation in forex?

When one currency pair goes up, the other follows it up by going in the same direction or the opposite. It is called currency correlation.

If a currency moves in tandem with the other, then they both have a positive correlation. If the movement is precisely the opposite, it is a negative correlation.

For instance, consider EUR/USD and GBP/USD. Since their movements are precisely identical, they have a positive correlation. Whereas, if you compare the EUR/USD with USD/CAD, you can see a slight negative correlation.

Owning 1 lot of EUR/USD and 1 lot of GBP/USD is equivalent to owning 2 lots of EUR/USD as both will either hit the target or stop loss in tandem. So, traders have to be aware of the correlated currency pairs as it could significantly increase the risk or could be used as a wise hedging tool.

The reason behind currency correlation in Forex

There are three primary reasons for currency correlation.

#One – Clubbing

The currencies are clubbed as pairs. So the same currency appears in multiple pairs. When there is a demand spike for a currency, it happens across the board. And traders get hold of it against every pair.

Take the case of EUR/USD and GBP/USD. They both have USD as the common denominator. So when the USD becomes weak, they both go up, whereas, when the USD becomes strong, they plunge together.

#Two – Interdependency

Some economies are interdependent. Generally, this happens with neighboring countries, say Australia and New Zealand, the US and Canada. So, when one makes a move, traders naturally take a speculative position on the other to follow it up.

#Three – Risk

When the investors wary that the financial markets are at risk, they embrace safe-haven assets like USD, JPY, and CHF. But, when the market is at its best, and they take the extra-mile of risk and acquire EUR, GBP, and AUD.

The spreadsheet has an inbuilt function (=CORREL). You can use it to find the correlation of any asset class.

We have put down the correlation of all the major forex pairs for the year 2018. If the value is close to 1, then it is a positive correlation. On the contrary, the value of -1 is a negative correlation.

Well, traders believed this correlation as a fixed affair in the forex market, until that time. And it was an easy deal, back then. But, here is the twist in the tale.

The Currency Correlations are not stone wall carvings

The year 2019 had a significant change in the store for us, traders. Some divorces and marriages took place, which could have been shocking even to the fans of Game of thrones.

Shock#1: EUR/USD and USD/JPY

Back in 2018, they were Tom and Jerry. Come 2019; they became Bonnie and Clyde.

When one went down, the other followed it down the hill.

It was a year-long downtrend for both the pairs making lows after lows.

And they were lame-duck sell candidates all through the summer.

Shock#2: Gold and Dollar

Well, this one was a bouncer. It defied the thumb rule of investing — gold goes down when the dollar goes up — and both went up. Hardly anyone had time to realize the inversion in correlation, a significant move happened.

Hence, investors played catch up, which resulted in the largest bull market in the bullion counter.

The yellow metal was too costly for non-Americans, yet the buying frenzy didn’t freeze. It only proved that investors were paranoid about the economy.

Shock#3: USD/JPY and AUD/USD

These currency pairs had a strong negative correlation, previously.

However, in 2019, their correlation changed to positive.

The US Dollar in both the counters witnessed a change in demand against AUD and JPY drastically, which could have caught many traders off-guard.

So the bottom line is, the currency correlation of forex pairs is not a stone wall carving.

It can change anytime due to the change in economic dynamics.

Let’s analyze the change that happened this year and in turn, expect what the future has in store for us.

What triggered the currency correlation change in 2019?

Donald Trump!

Trade War!

US-China: Fire in the Hole!

US China trade war

The trade war disrupted the forex movements and correlation, all through the year.

Economics took a backseat, and politics became the reckless driver of the market. Hence, traders had glued themselves to Trump’s Twitter handle and Chinese newspapers rather than the charts.

Each time a tariff was imposed by either of the countries, the market ran for cover. And the cover was obviously provided by Gold, US Dollar, and Japanese Yen. So traders bought piled up all three irrespective of their correlation.

Amid these roller coaster rides in the market, one indicator outperformed the custom indicators. Care to know?

Why did the market choose these 3 assets?


Gold is a safe haven for the investing community. Whenever a mishap happened, the market generally braced it. So it wasn’t a howler, that traders piled up gold during uncertain times. (Want to handle uncertainty like a pro? Here are 4 amazing tips!)

US Dollar

But the uptick in USD,  the arch-rival of Gold, made many traders go bonkers. And here are the reasons for its change in currency correlation with its peers.

#One– The US economy was stronger compared to other developed economies. The rest of the world experienced a slowdown. And as the trade war progresses, it could only worsen for other countries, say Australia, Eurozone. Whereas the US economy showed signs of resilience, as the job data came out with flying colors month-on-month.

#Two– The tariff imposed by the US filled its coffers and hence, the trade deficit narrowed a bit, which was a good sign for the short-term.

#Three– A trade war between the heavyweights — US and China — made recession an inevitability to many of the ailing economies and so investing community didn’t have much choice to put their money into work. So, they parked their money in the one they felt comfortable.

#Four– The US central bank was the lone hawk among the crowded doves. As the interest rate rose, the currency also naturally spike.

Japanese Yen

Japanese Yen had been the Forex community’s go-to asset during the low-interest regime, historically.

Since the central banks around the world were cutting interest rates to counter the menacing effect of the trade war, investors took shelter in the Y-shaped hut.

Trade war or not, JPY would have outperformed the market since most central banks were dovish throughout the year.

Are you confused about how to overcome these economic mumbo-jumbos technically? Here is the next-gen indicator that could ease your worries.

Is trade war potent enough to change the course of the economy?

Big Yes.

The west has a developed economy. Since they are saturated, their growth potential is low.

However, it is the east, which has developing nations and a large mass of consumers – say China and India. They have been the most significant contributors to world GDP (Gross Domestic Product) in the past decade.

The trade war crippled China as its exports lost the glittering factor of low cost. The repercussions were acute, and it started reflecting in their investment and production numbers.

As a result, the world’s GDP took a dent. The future forecasts of the GDP were also pessimistic.

Ergo, the investing community was right to panic so.

What 2020 has in store for us?

It’s the Euro time!

US and Eurozone Trade war

Well, this one is still in a foreplay period. The US has been teasing the Eurozone with tough rhetorics on the trade balance. Though it hasn’t reached the front page yet, investors wary that it might happen soon.

And it could have a far more catastrophic effect than the US-China trade war. The US exported 574.5 billion worth of goods to Europe, whereas only 179.2 goods to China, in 2018, according to data from US Trade Representative. Hence, a retaliation tariff from Eurozone could make the US economy bleed as well, which didn’t happen so during the Chinese fight back.

And this blood bath could unlock a vicious chain of events in the currency correlation forefront, which is hard to predict now.


Euro and British Pound have been identical twins in the past.

It is because of their closely related economies.

However, the Brexit divorce could change their economic behavior as well. A shift in trade and economic policies could have a direct impact on foreign capital inflows to Britain. And the working conditions and wages of laborers will have a direct say on inflation, which is a significant concern for any central bank.

So the details lie in the fine print of the deal.

If Britain stalks and follows Euro like a scorned ex-lover in its policies, owing to the deal, then their forex correlation wouldn’t see a tweak.

On the flip side, if they part their ways in diagonally opposite roads, and Britain retains its free-will to sign deals with other countries, then their correlation could falter as well.

So, don’t get ambushed by anticipating a parallel move, after the exit! We said it here, first!


The currency correlation is not a fixed affair in the forex market.

It’s like a marriage; sometimes, the couple tends to be life long partners while some divorce.

So, we advise you to check the correlation using the formula or with the help of an excel sheet periodically, say monthly or weekly.

Make your trading decision with the backing of facts rather than assumptions or hopes.

Or trade the currency to the merit of their charts rather than merely trusting on the correlation. Here are some tips to create an effective trading plan for further reading.
