Although I would love to claim some skill as an investor, the most important lesson of my experience over the past few years is that luck matters far more than many would like to admit. Yet another reminder of this surfaced recently in the shape of the annual statement for my index-linked savings certificates. These are fixed-term, tax-free deposits offered by National Savings & Investments that pay a rate of interest linked to inflation: in this case, 1 per cent above the retail prices index (RPI) for three years.
In the days when we still had inflation, these certificates were popular with cautious investors looking to protect the value of their capital. In July 2010, I put in the maximum permitted in the belief that inflation was bound to pick up at some point given the amount of money that was being created. Two weeks later, the Treasury abruptly withdrew index-linked savings certificates from sale and although they were briefly relaunched the following year they quickly disappeared again and have not been seen since.
That was the first of several lucky breaks. Almost immediately, inflation picked up strongly and hovered around 4-5 per cent for much of 2011 and 2012, delivering me a return of 5-6 per cent with no tax and no risk. Then, very soon after I had invested, the government began switching to a different measure of inflation, abandoning RPI in favour of the consumer price index (CPI) as the benchmark for calculating annual increases in all sorts of welfare payments.
