The impact of higher interest rates on stocks

On Friday, the jobs report came out and it was a strong report. The consensus was expecting 180,000 new jobs in January and the actual number released on Friday ended up being 200,000. So why did the markets drop? The answer: wage growth. The jobs report not only contains how many new employees were hired but it also includes the amount that wages for the current workforce either increased or decreased on a year over year basis. The report on Friday indicated that wages went up by 2.9% year over year. That is the strongest wage growth number since 2009.

Double Edged Sword

Wage growth is a double edged sword. On the positive side, when wages are going up, people have more money in their paychecks which allows them to spend more and consumer spending makes up 70% of our GDP in the United States. I’m actually surprised the market did not see this coming. The whole premise behind tax reform was “if we give U.S. corporations a tax break, they will use that money to hire more employees and increase wages.” The big question people had with the tax reform was “would the trickle down of the dollars saved by the corporations eventually make it to the employees pockets?” Many corporations in January, as a result of tax reform, announced employee bonuses and increases to the minimum wage paid within their organizations. The wage growth number on Friday would seem to imply that this is happening. So again, I’m actually surprised that the market was not ready for this and while the market reacted negatively I see this more as a positive long term trend, instead of a negative one. If instead the U.S. corporations decided not to give the bonuses or increase wages for employees and just use the money from the tax reform savings to increase dividends or share buybacks, then you probably would have seen only a moderate increase in the wage growth number. But that also would imply that there would be no “trickle down” effect to the middle class.

The Downside

This all sounds really positive but what is the downside to wage growth? While wage growth is good for employees, it’s bad for corporate earnings. If I was paying Employee A $50,000 in 2017 but now I’m paying them $55,000 per year in 2018, assuming the output of that employee did not change, the expenses to the company just went up by $5,000 per year. Now multiply that over thousands of employees. It’s a simple fact that higher expenses without higher output equals lower profits.

Wage Growth = Inflation

There is another downside to wage growth. Wage growth is the single largest contributor to inflation. Inflation is what we use to measure the increase in the price of goods and services in the U.S.. Why are these two measurements so closely related? If your salary just increased by $300 per month, when you go to the grocery store to buy milk, you may not notice that the price of milk went up by $0.15 over last week because you are making more in your paycheck. That is inflation. The price of everything starts going up because, in general, consumers have more take home pay and it gives the sellers of goods and services more pricing power. Visa versa, when the economy is in a recession, people are losing their jobs, and wages are decreasing. If you sell cars and you decided to raise the price of the cars that you sell, that may cause the consumer to not buy from you and look for a lower priced alternative. Companies have less pricing power when the economy is contracting and you typically have “deflation” not inflation.

When Does Inflation Become Harmful?

Some inflation is good. It means the economy is doing well. A rapid increase in inflation is bad because it forces the Fed to use monetary policy to slow down the economy so it does not over heat. The Fed uses the Federal Funds Rate as their primary tool to keep inflation in check. When inflation starts heating up, the Fed will often raise the Fed Funds Rate to increase the cost of lending which in turn reduces the demand for lending. It’s like tapping the brakes in your car to make sure you do not accelerate too quickly and then go flying off the road.

If some inflation is good but too much inflation is bad, the question is at what point do higher interest rates really jeopardize economic growth? The chart below provides us with guidance as to what has happened in the past when interest rates were on the rise.

correlation between interest rates and stocks

The chart compares every 2 year period in the stock market versus the level of the 10-Year Treasury yield between 1963 – 2017. For example, one dot would represent the time period 1963 – 1964. Another dot would represent 1964 – 1965 and so on. If the dot is above the “0.0” line, that means that there was a “positive correlation” between stock prices going up and the interest rate on the 10-Year Treasury yield going up during that same time period. Worded another way, when the dot is above the line that means the stock market was going up while interest rates were also increasing. In general, the dots above the line are good, when they are below the line, that’s bad.

Right now the 10-Year Treasury Bond is at 2.85% which is the red line on the chart. What we can conclude from this is going all the way back to 1963, at this data point, there has never been a two year period where interest rates were rising and stock prices were falling. Could it be different this time? It could, but it’s a low probability if we use historical data as our guide. History would suggest that we do not run into trouble until the yield on the 10-Year Treasury Bond gets above 4%. Once the yield on our 10-Year Treasury Bond reaches that level and interest rates are rising, historically the correlation between rising interest rates and stock prices turns negative. Meaning interest rates are going up but stock prices are going down.

It makes sense. Even though interest rates are moving up right now, they are still at historically low levels. So lending is still “cheap” by historical standards which will continue to fuel growth in the economy.

A Gradual Rise In Interest Rates

Most fixed income managers that we speak with are expecting a gradual rise in interest rates throughout 2018. While we expect interest rates to move higher throughout the year due to an increase in wage growth as a result of a tighter labor market, in our opinion, it’s a stretch to make the case that the yield on the 10-year Treasury will be at 4% by the end of the year.

If the U.S. was the only country in the world, I would feel differently. Our economy is continuing to grow, wages are increasing, the labor markets are tight which requires companies to pay more for good employees, and all of these factors would warrant a dramatic increase in the rate of inflation. But we are not the only country in the world and the interest rate environment in the U.S. is impacted by global rates.

The chart below illustrates the yield on a 10 year government bonds for the U.S., Japan, Germany, UK, Italy, Spain, and total “Global Ex-U.S.”.

global interest rates

On December 31, 2017 the yield on a 10-Year Government Bond in the U.S. was 2.71%. The yield on a 10-Year government bond in Germany was only 0.46%. So, if you bought a 10-Year Government Bond from Germany, they are going to hand you back a measly 0.46% in interest each year for the next 10 years.

Why is this important? The argument can be made that while the changes in the Fed Funds Rate may have a meaningful impact on short-term rates, it may have less of an impact on intermediate to longer term interest rates. When the U.S. government needs more money to spend they conduct “treasury auctions”. The government announces that on a specified date that they are going to be selling “30 million worth of 10-year treasury bonds at a 2.8% rate”. As long as there is enough demand to sell all of the bonds at the 2.8% rate, the auction is a success. If there is not enough demand, then they may have to increase the interest rate from 2.8% to 3% to sell all $30 million worth of the bonds. While the U.S. 10-Year Treasury Bond only had a yield of 2.71%, it’s a lot higher than the other trusted government lenders around the world. As you can see in the chart above, the average 10-year government bond yield excluding the U.S. is 1.03%. This keeps the demand for U.S. debt high without the need to dramatically increase the interest rate on new government debt issuance to attract buyers of the debt.

As for the trend in global interest rates, you will see in the chart that from September 30, 2017 to December 31, 2017, global 10-year government bond yields ex-U.S. decreased from 1.05% to 1.03%. While we are in the monetary tightening cycle in the U.S., there is still monetary easing happening around the world as a whole which should prevent our 10-year treasury yields from spiking over the next 12 months.

Impact on Investment Portfolios

The media will continue to pounce on this story about “the risk of rising interest rates and inflation” throughout 2018 but it’s important to keep it in context. If tax reform works the way that it’s supposed to, wage growth should continue but we may not see the positive impact of increased consumer spending due to the wage growth until corporate earnings are released for the first and second quarter of 2018. We just have to wait to see how the strength of consumer spending nets out against the pressure on corporate earnings from higher wages.

However, investors should be looking at the fixed income portion of their portfolio to make sure there is the right mix of bonds if inflation is expected to rise throughout the year. Bond duration and credit quality will play an important role in your fixed income portfolio in 2018.
