The Retired Investor: U.S. Treasuries Not Risk Free
By Bill Schmick, iBerkshires columnist

The recent calamity in the banking sector is complicated, but one issue stands out. Even the safest of investments have risk.
Understanding the relationship between bond prices and interest rates is extremely important. Bonds, overall, are considered safer investments than stocks and history indicates that bonds have been less volatile than stocks most of the time. However, when interest rates rise, bonds can get hurt for a variety of reasons, and credit risk is at the top of the list.
Credit risk refers to the possibility that a corporation (or a government entity) could default on a bond they have issued. That happens when the issuer fails to pay back the principal or cannot make interest payments. Normally, U.S. government bonds, called Treasuries, have lower credit risk. Presently, however, even Treasuries have some credit risk. If Congress refuses to increase the debt limit by this summer and allows the country to default, the consequences for our government debt could be grave.
However, all bonds have interest rate and duration risk. Bond prices and interest rates move in opposite directions. As interest rates fall (as they have for much of the past decade), the value of fixed-income investments rise. Since last year, interest rates have risen substantially due to the Federal Reserve Bank's efforts to combat inflation.
This is where duration risk comes in. Let's say you have long-dated U.S. Treasury bonds that do not come to maturity for 10, 20 or even 30 years from now. If you hold them to maturity, you will receive your principal investment back plus whatever interest rate coupon was promised. However, if rates rise (as they are doing now), and for whatever reason, you sell your bonds before their maturity date, you could end up receiving less than what you paid for your bond.
In general, duration is expressed in terms of years and generally bonds with long maturities and low coupons have the longest duration. These bonds are more sensitive to a change in market interest rates and thus are more volatile in a changing interest rate environment. Over the last year, the Fed has increased interest rates at its fastest pace in recent history, which has caused the price of bond holdings to decline substantially.
Enter the Silicon Valley Bank (SVB) stage left. SVB, like most banks, relies on a mixture of short-term and long-term financing. The short-term side largely consists of customer deposits. A bank's assets typically consist of long-term loans that get paid back with interest over time as well as bonds the bank purchases that pay out over the term of the bond.
More than half of SVB's assets at the end of last year were "safe" bonds issued by the U.S. government or federal mortgage institutions, which they had purchased before the Fed's tightening policies began. Safe from default risk, maybe, but not from the climbing interest rates. And most, if not all, of those bonds, were low coupon, and long-term in nature — a classic case of duration risk.
The nightmare that all banks fear is a bank run. Think of "It's a Wonderful Life" and George Bailey's Building and Loan, a small community bank in Bedford Falls. Depression-era depositors, fearing for their financial lives, rushed to take their money out of Bailey's bank. Few depositors understood how credit and loans work. They thought their money was simply sitting in the safe. George tried to explain the concept but ended up making good for his customers by giving them his honeymoon money.
In the case of SVB, the same thing occurred, although, unlike George Bailey, the management of the bank could not make their depositors whole. For most depositors, there was no need to stand in line. A simple electronic transfer via computer transferred millions out of the bank in seconds. As a result, SVB was forced to sell bonds at a loss to satisfy depositor demands until it couldn't. The rest is history.
What may some readers have in common with SVB? In today's market, there has been a mad rush to capture higher interest returns after years of an interest rate famine. The U.S. Treasury markets, especially on the short end, have seen yields of 5 percent or above for six-month, one-year, and two-year notes and bills.
Putting excess cash into these high-yielding instruments and intending to hold them to maturity is a reasonable financial strategy. However, if you need to sell them to raise cash for an emergency may leave you open to losses. Remember that a bond's yield is not the same as the interest rate coupon promised at maturity on that instrument.
A six-month note may have been issued with a fixed 1.75 percent coupon, however, because of the Fed's recent interest rate hikes, the price of the note has declined. As it does the yield has climbed. 
You are in effect, buying that note at a discount to the original purchase price. If you hold the instrument to maturity, you will receive the full-face value of the note when it was issued, plus the coupon. That is ideal. But remember, yields will go up and down over time in an inverse relationship with the instrument's price depending on market conditions. If things change and you need to sell early, you may face the same issues as SVB. That is the risk you are taking when you buy Treasuries.
