- The dollar has been positively correlated with stocks for the last 4 years which is unusual.
- Potential FED interest rate increases don’t make international diversification a great idea right now.
- Any sign of a U.S. recession should be a good time to think about international diversification with emerging markets.
On big news sites like Bloomberg you often come across headlines related to the movement of the U.S. dollar. The headline below is a good example.
Such headlines relay what has been going on in the few hours before publication but are completely irrelevant for investors that aren’t trading pips on forex. This article is going to investigate the longer term relationship between the dollar and stocks, and discuss the best option for maximum return with minimal risk.
Recent Dollar & Stocks Movements
Before 2012, as the dollar strengthened, stocks went down and vice versa. The reason was simple, a strong dollar meant U.S. exports were less competitive and businesses suffered, while a weak dollar made U.S. goods cheaper across the world and increased corporate earnings. Since 2012, however, the story has been a little bit different. The dollar has gotten stronger and stocks have gone higher.

The reason behind this is the fact that no matter what we think of the FED, it is the most globally coherent financial institution. In an environment where the European central bank is continuing with stimulus and the Japanese think about printing money for direct spending, the FED is the only institution that contemplates raising interest rates. So the positive correlation between the U.S. dollar and the S&P 500 comes from the relative success of the U.S. economy and the global faith in the U.S. dollar as the only safe currency.
On one hand, the strong dollar lowers corporate revenue. But on the other hand, it also lowers corporate costs, something CEOs never talk about when reporting earnings. As the U.S. has a net trade deficit, the strong U.S. dollar makes everything around the world cheaper and therefore expenses should also be much lower. Don’t forget this in the next earnings season.
Long Term Dollar Strength
The long term perspective is a little bit different than the above. Since 1975, the dollar has slowly but consistently weakened in relation to foreign currencies.

The slow decline of the dollar means that global trends are shifting, which is also normal given the development in China and other countries. As the rest of the world is expected to grow at a faster rate than the U.S., the long term trend for the dollar is clearly and slowly downwards. This point is essential for international diversification. We have discussed many times how China, India and other fast growing emerging markets are essential for healthy diversification.
Forecasts & Economic Factors
In the short to medium term, it looks like the dollar is going to continue to strengthen. If the FED increases interest rates and others continue with their stimulus, the dollar will surge even higher. The most recent FOMC minutes clearly indicate that we could see a rate hike by the end of the year. But, eventually the strength of the dollar will kick back as exports will be more expensive and the trend will turn and continue to follow the declining line seen in figure 3 above.
What To Do
There are two options with currencies. They go up or down and do so for longer periods until the structural influences rebalance on a global scale. With interest rates low and good news from the U.S. economy, the FED will eventually raise interest rates and send the dollar higher. The moment of maximum strength of the U.S. economy and the dollar will be the time to diversify to other currencies but until then, sticking to the dollar is not a bad idea, especially for the majority of our readers who are living in the U.S. If the U.S. economy slows down and the dollar weakens, you will still have most of your assets in your home currency which will not represent a real change to your portfolio. But if you are exposed to other currencies and the dollar gets stronger, you will have to look at losses, which is never pretty.
U.S. investors have the benefit that if the dollar gets weaker, international diversification is just a missed opportunity while if the dollar gets stronger, it was a good idea to stay at home. International investors have to play it differently. With the FED eventually increasing rates, the dollar has no other direction to go than up which is a great diversification play when looking at the stimulus in Europe and Japan which weakens their currencies.
In the long term, it pays to be exposed to the currencies of the countries that are going to grow at a faster pace than the U.S. economy, i.e. emerging markets. We have seen the Chinese Yuan get weaker in the past two years due to some fears about China slowing down, but the longer term trend is clear.

With the economy expected to grow at a pace of above 6% in the next 10 years and the Chinese getting richer, there is only one way for their currency, up. Think about international diversification, but only when the dollar strength reaches its structural limits and the U.S. is close to a recession.
