This is a very small increase in risk for quite a healthy uptick in return.
Unlike term deposits which have no capital fluctuations, the capital value of bonds can go up, or down, however, if you hold a bond to maturity, you should have a known outcome. Fixed rate bonds are more affected by capital fluctuations than floating rate bonds however when we are at, or near, the top of the interest rate cycle, chances are that movement might work in your favour.
This is one of the other key benefits of fixed rate bonds at this point in the cycle. They give you the ability to lock in a consistent income return of, say, 6%+ now. When interest rates fall, you will keep collecting that income and you are likely to benefit from some capital uplift.
One of the drawbacks of term deposits that was not mentioned above is refinancing risk. If you are regularly rolling term deposits, then you are at the mercy of the market at every time you roll. This is likely to work in your favour as interest rates are rising however the corollary is also true. If you lock in 5% for the next 12 months there is no way of knowing the level that term deposit rates will be in a years’ time. In contrast in a bond where you have locked in that return for the life of the bond.
Whilst flexibility was one of the other key drawbacks of term deposits, it is a strength of bonds. In normal market conditions an investment grade bond would usually be able to be sold within a few days.
Timing of cashflows is also relevant for some investors with term deposits only paying interest at the end of the term compared to bonds which pay income twice or four times a year.
As mentioned, there is room for both term deposits and bonds in a portfolio. Especially given the returns on both are relatively attractive at present. My personal view is that bonds currently offer a healthy yield premium over term deposits for only a relatively minimal increase in risk and much greater flexibility. The ability to lock in attractive returns at, or near, the top of the interest rate cycle also makes bonds look very appealing at present. So, I am currently favouring a stronger weighting to bonds over term deposits.
