This link is not relevant. What the OP is asking about is not a real bond as the rest of the world knows it but an Irish bond which is really a capital protected investment product.
Off the top of my head you could get about the same return by putting 50% into an etf that tracks emerging markets and the rest in the best term deposit you can find.
You don't get complete downside protection but allowing for higher charges, dividends(not paid by the bond) risk control elements incorporated into the bond which will lower return and interest on the capital on deposit after year one you will get about the same upside return.
Also this bond is priced at Dec 10th prices. Emerging markets have stumbled since so it's possible the index is now lower than the price you will pay in the bond.
What % of your total portfolio is this going to be?
On a personal note I wouldn't be putting 25k into emerging markets now. They have had an enormous run over the last few years. Reversion to the mean and all of that.
