@benlola Just FYI, the yield is only part of the return. The long-term return annualizes out to about 2.8% as per Vanguard. Of course, it’s variable and so the additional risk factor is the potential loss of premium. Conversely, unlike Toyota you would not lose 100% in any event and I think the lowest drop ever was something like 2%.
Bond investing in a very low interest rate environment is incredibly challenging.
