Rates Are Rising. Is It Time to Sell Your Bonds?

With interest rates still close to historic lows there has been lots of talk about how rising interest rates will reduce bond values. This hasn’t been helped by President Trump’s trade war threats, which have the potential of causing rising prices and higher inflation.

The Federal Reserve has raised rates six times in the past three years. Even though rates are rising, there are still many reasons to hold bonds. One of the most important is that a portfolio that includes bonds will help investors weather the storms of the stock market and keep them invested, rather than selling when stocks drop. If you don’t stay invested in stocks, it is unlikely that you will keep pace with inflation, which could jeopardize your reaching your financial goals. In fact, if the recent market volatility made you a little jittery, you may actually want to increase your bond exposure now, rather than reduce it.

Making a Case for Bonds

Let’s start by examining the reason you added bonds to your portfolio in the first place. The main reason to buy bonds is to have an asset that hopefully grows faster than cash investments, like bank accounts and money market funds, but doesn’t drop — or at least not as much — as stocks can drop. So, we anticipate that bonds will provide returns somewhere around 4% to 5% over time, which is somewhere between cash, with returns between 1% and 2%, and stocks, historically at 8% to 10%.

If stocks take a turn for the worse, we hope bonds will cushion the fall. Has this been the case? Let’s look back at a couple of past periods and see if this held true — bonds helping a portfolio when stocks fell.

• This was the case in 2008. Stocks, as measured by the S&P 500 index, were down in 2008 (37%), while intermediate Treasury bonds were up 11.35% and international bonds were up 10.11%. Corporate bonds fell, but not by much (2.76%).
• How about in 2002? The S&P 500 index fell (22.09%) while government bonds, corporate bonds and international bonds were up 9.28%, 10.14% and 21.99% respectively.

So, in our last two big market pullbacks bonds would have given your portfolio a boost.

How Have Bonds Performed in Times of Rising Rates?

The Federal Reserve uses the fed funds rate as a tool to control inflation. Let’s look at interest rates and inflation and how they interact with bond values. The question we must answer is, if inflation increases and the Federal Reserve raises rates, what will that do to your bond portfolio? Let’s use one of the worst inflationary periods we’ve ever encountered as our guide. From 1970 to 1980 inflation went from a low of 5.4% to a high of 14.8% as measured by the consumer price index (or 10.99% per year). During this same period the fed funds rate increased from 6.13% to 19.85%. To jog your memory, this is the time when a 30-year mortgage came with a 13.74% interest rate.

While rates were increasing, what happened to bonds? To answer this question, I ran a hypothetical illustration using Morningstar and two bond funds that have been around a long time. I took those two funds — a government bond fund and a corporate bond fund — and ran them through the period 1970-1980. Let’s assume you added $10,000 to the Putnam Income A fund, a corporate bond fund, and another $10,000 into the Franklin U.S. Government Bond A, a government bond fund, from Aug. 1, 1970, and stayed invested until March 31, 1980. Let’s also assume the two-fund portfolio was rebalanced every six-months and that no sales charges were paid, since these funds can be purchased on many brokerage platforms with their loads waived.

By March 31, 1980 your $20,000 portfolio would have grown to $30,094 for a return of 50.47% or 4.32% per year. So, while inflation increased 174% and interest rates went up 224%, your bond portfolio would have gained 50.47%.

Isn’t this exactly what we have been warned about? If rates go up, aren’t bond values supposed to go down? That didn’t hold true from 1970-1980. Rates skyrocketed and bonds still went up. What explains this rule-busting performance?

This is a good time to discuss nominal versus relative returns. In nominal terms your portfolio did go up 50.47%. This is about what we’d expect from bonds, 4.32% per year. However, in relative terms, since inflation increased so much during this 10-year stretch your portfolio that grew to $30,094 couldn’t buy what your initial $20,000 could buy in 1970. For example, you would need $2.74 in 1980 to buy what $1.00 could buy you in 1970. That’s a 10.9% annual increase. Another way of putting it is you would need $54,800 in 1980 to buy what $20,000 bought in 1970. So, while your bond portfolio went up in value it didn’t keep pace with inflation.

What has happened to interest rates lately? Since 2015 the Federal Reserve has raised the fed funds rate six times from a low of 0.06% to 1.75% today. That is a whopping 2,800%+ increase! During this time your two-fund bond portfolio would have remained flat. A $20,000 investment split equally into the two bond funds on Jan. 1, 2015, would now be worth $20,741. During this time we’ve had some modest inflation. For example, in 2015 inflation averaged 0.01% and now sits at 2.2%. In both cases, 1970-1980 and 2015 to now, interest rates have risen, but bonds, in nominal terms, rose or remained fairly constant.

Bonds’ True Worth for Investors: A Valuable Hedge

The real reason you need bonds is not to make a big return or keep pace with inflation, but rather to keep you invested when stocks are failing. Staying in stocks for the long-term is your best bet to combat inflation. However, most investors can’t own just stocks and endure the volatility that comes along with a stock-only portfolio. Buying stocks just to turn around and sell them when things get uncomfortable is almost a guarantee of lower returns. For example, in 2008, when the S&P 500 index dropped by 37%, many people sold out of stocks and didn’t get back in to capture the upside when the market turned around in 2009.

The question to ask yourself is, can you handle a 37% drop in your portfolio? If not, adding bonds to your portfolio is a way to reduce volatility to the point that you can tolerate the volatility of stocks.

A Tale of 3 Portfolios

Let’s see how our two-bond portfolio did if we team it up with a stock fund over the same time from 1970-1980. Let’s test four portfolios; one that is 100% bonds, a second that is a mix of 50% stocks and 50% bonds, a third that is 75% stocks and 25% bonds, and a fourth that is 100% stocks. In three of the portfolios I tested I assumed that we added the Vanguard Windsor Investor Fund to our two-bond portfolio from Aug. 1, 1970, until March 31, 1980 (the same period we tested previously) and rebalanced every six months. This is the same period we looked at earlier that saw massive inflation and interest rate increases.

With each portfolio notice what happened during the worst two years of the decade, 1973 & 1974. You’ll notice in the first example that our two-bond portfolio cushioned the fall of the recession in 1973 and 1974. While stocks fell (15%) and (26%), our two-bond portfolio fell, but by quite a bit less (0.64%) and (2.48%).

Portfolio 1: 100% Bonds

• Portfolio mix: 50% Franklin U.S. Government Bond A and 50% Putnam Income A
• Beginning value (Aug. 1, 1970): $20,000
• Ending value (March 31,1980): $30,094
• Annualized return: 4.32%
• Return in 1973: -0.64%
• Return in 1974: -2.48%

Portfolio 2: 50% Stocks & 50% Bonds

• Portfolio mix: 25% Franklin U.S. Government Bond A, 25% Putnam Income A and 50% Vanguard Windsor Investor
• Beginning value (Aug. 1, 1970): $20,000
• Ending value (March 31, 1980): $38,976
• Annualized return: 7.15%
• Return in 1973: -13.44%
• Return in 1974: -9.76%

Portfolio 3: 75% Stocks & 25% Bonds

• Portfolio mix: 12.5% Franklin U.S. Government Bond A, 12.5% Putnam Income A and 75% Vanguard Windsor Investor
• Beginning value (Aug. 1, 1970): $20,000
• Ending value (March 31, 1980): $43,702
• Annualized return: 8.42%
• Return in 1973: -19.38%
• Return in 1974: -13.31%

Portfolio 4: 100% Stocks

• Portfolio mix: 100% Vanguard Windsor Investor
• Beginning value (Aug. 1, 1970): $20,000
• Ending value (March 31, 1980): $48,553
• Annualized return: 9.61%
• Return in 1973: -25.02%
• Return in 1974: -16.80%

You’ll remember that you needed $54,800 in 1980 to buy what $20,000 bought in 1970. It’s interesting to note that the 100% stock portfolio finished at $48,553 in our example, not quite keeping pace with inflation. However, had we changed our end date to two months earlier, Jan. 31, 1980, the balance would have been $54,716, essentially keeping pace with inflation. A balanced portfolio should be able to stay ahead or even a little higher than average inflation.

For example, if, for this 10-year period, you had experienced 5% inflation, you would have needed $32,053 to buy what the $20,000 bought in 1970. If inflation was 5%, each portfolio I tested with stocks would have kept you ahead of inflation.

How Concerned Investors Can Rein in Bond Risk Right Now

If you are worried about bonds, there are a couple of things you can do. You can reduce the risk to your bond portfolio by 1) reducing the maturity of the bonds in your portfolio, 2) buying higher quality bonds, and by 3) further diversifying your bond portfolio. For example, most people don’t own international bonds in their portfolios, however this was a spot in 2002 and 2008 that provided good returns.

We’ve had a little pressure on the stock market already this year. Now would be a good time for a gut check. If you’re already queasy about stock market volatility, you may want to lighten your stock load and increase bonds. Increasing bonds by 5% to 10% might be a good move for you, especially if it keeps you from selling your long-term stock positions.

Again, the goal is to get the right mix of stocks and bonds so we get your risk down to a level where you won’t be tempted to sell stocks if they fall. While stocks are down a little for the year as of early April, they are still 366% better than they were on March 9, 2009. So, if you chip away some stocks now to buy bonds, you’d still be selling stocks at almost all-time highs and protecting those gains by re-allocating that money to bonds.
