The professional framing
A bond ETF should usually make your portfolio steadier, simpler, or easier to match against future spending. If you are choosing it because the yield line looks tempting, you are probably starting from the wrong question.
AGGU or VAGP — broad bond ballast
Both are legitimate broad-bond answers when you want one diversified fixed-income sleeve rather than hand-picking credit and duration risk.
Global aggregate
- Good for diversified ballast rather than a yield punt.
- GBP-hedged framing matters for UK investors because it reduces FX noise.
- Usually the strongest default when bonds are there to stabilise a mixed portfolio.
VGOV — plain gilt exposure
Cleaner when you specifically want UK government bonds and you want to understand exactly what the defensive sleeve is made of.
UK gilts
- Useful for sterling liabilities and more transparent than a mixed global aggregate fund.
- Still rate-sensitive; “government bond” does not mean “price never moves”.
- Best when the simplicity of gilts is the point.
Which bond ETF route fits which problem?
| Investor problem |
Likely best route |
Why |
| I want one broad bond sleeve inside a mixed portfolio. |
AGGU or VAGP |
They do the diversified ballast job cleanly without forcing you to manage multiple bond segments manually. |
| I want explicit UK government-bond exposure. |
VGOV |
That is a clearer match when you want gilts, not a global mix of government and corporate bonds. |
| I mainly care about income. |
Recheck the job |
Bond ETFs bought only for yield can disappoint if the real goal was stability, cash flow planning, or inflation matching. |
Common mistake: mixing “defensive” and “income” goals without realising they can point to different bond structures and different duration risk.
