How do you select one of the best bond funds or bond ETFs from the bewildering array of merchandise out there?
Many traders discover bonds deeply unintuitive – and the asset class’s inflation-fuelled crash in 2022 hasn’t precisely impressed them to dig deeper.
But a strong allocation to high-quality authorities bonds stays the primary cease on the subject of strategically diversifying a portfolio dominated by equities.
And that is still true even after final yr’s once-in-a-generation carnage, when these hoped-for diversification advantages really failed to indicate up.
Curiosity-ing bonds
It looks like a great time to take a deep breath and a step again.
We’ve beforehand defined the purpose of bonds inside a passive investing portfolio.
For UK traders, it boils all the way down to investing in UK authorities bonds (referred to as gilts) and/or the federal government bonds of different developed markets. Such bonds are the likeliest to cushion your equities when inventory markets plunge. And that’s simply what we would like our bonds for. (Equities can ship the long-term returns – supplied we maintain on to them…)
We consider one of the best bond fund automobiles are ETFs and index funds. That’s as a result of their low charges go away extra return within the pockets of traders – versus fat-cat fund managers. (See under for extra on the ‘ongoing cost determine’, or OCF).
We’ll clarify our decisions under, however first let’s run by our picks for one of the best bond ETFs and bond index funds. We’ll do gilts first, after which international authorities bonds additional under.
Greatest bond funds and ETFs – UK gilts
Supply: Fund suppliers’ knowledge / Morningstar (A touch means knowledge not supplied).
YTM is yield-to-maturity. ‘Lux’ is Luxembourg.
These are intermediate gilt ETFs and funds as a result of, for many traders, intermediates supply a greater steadiness of risk versus reward than lengthy bonds (far riskier) or quick bonds (a miserly reward).
Devoted lengthy or quick bond allocations can be proper for some individuals, although.
There may be little to separate the funds within the desk. That’s simply appropriately! Competitors between index tracker suppliers is fierce, so most benefits have by now been eroded away.
You might be assured you’re in the suitable ballpark as long as you select an inexpensive bond ETF or bond fund, with a great monitor document amongst its friends.
Extra on that under. However first a few notes concerning the bond options picked out within the desk.
Ongoing Cost Determine (OCF)
The OCF is the annual value of the product charged to you by the fund supplier, as a share of your holding. So when you personal £10,000 value of a fund then a 0.1% OCF means you’ll pay round £10 in charges.
Decrease prices are at all times higher. Costs matter.
Period
Common duration is an approximate information to how a lot a bond fund will achieve or lose in response to a 1% change in market rates of interest.
For instance:
- A bond fund with a length of 10 will lose round 10% of its market worth for each 1% rise in its rate of interest.
- The fund’s value will equally soar about 10% if its price drops by 1%.
The upper a bond’s length, the larger the capital achieve or loss as its market rate of interest fluctuates.
The market rate of interest of a bond is not the bottom price set by the Financial institution Of England. The market rate of interest is a product of provide and demand for every particular person bond on the bond market. If the Financial institution Base Price is hiked by 1%, that doesn’t imply each bond will comply with swimsuit.
Yield-to-maturity (YTM)
The expected annual return of your bond fund is its present yield-to-maturity.
This quantity will fluctuate as bond prices transfer. However the principle takeaway is that there’s nothing between these merchandise. (Be aware that after we discuss with yield on this article, we’re speaking about YTM).
Credit score high quality
It is a guesstimate of the monetary energy of the bond issuer. (That’s the UK Authorities within the case of the gilt funds within the desk above.)
AAA is top-notch whereas BBB- units the ground for funding grade. Beneath that’s ‘junk’.
The upper the credit score high quality score, the higher. It means there’s much less probability the issuer will default on funds, at the least in line with the bond score businesses.
Bond score methods and verdicts fluctuate barely by company however our important message can be to stay to funding grade.
In different phrases, don’t contact another person’s junk.
Bond fund credit score high quality is the weighted common of all its bonds rankings.
Domicile
Location issues as a result of funds primarily based within the UK profit from FSCS investment protection. With that you may be eligible for compensation ought to your funding supplier go bankrupt.
True, it’s extremely unlikely that you just’ll ever want to fret about this provision, particularly given the size of the large fund outlets in our desk. But it surely’s a wrinkle value understanding about.
Transferring on, how have our greatest bond funds carried out this previous decade?
Greatest bond funds and ETFs – UK gilts outcomes verify

Supply: Trustnet multi-charting tool
We’ve expanded our product scope for this efficiency verify. Partly as a result of doing so illustrates some helpful factors about bond funds, and partly to once more present there’s little to decide on between good index trackers.
We’ve highlighted the candidates’ 10-year annualised returns (nominal) inside the inexperienced field as a result of the longer the timeframe, the extra significant our comparability.
The cyan strains underscore the principle indexes tracked by one of the best bond funds.
With mates like these…
One factor leaps out instantly from our efficiency verify: bond returns over the interval have been completely horrible.
A near-zero return over ten years – and stiff losses over tighter time durations – does make you marvel why you’d trouble with bonds.
The very fact is that sadly your complete asset class was smashed in 2022 as rates of interest surged and rising bond yields inflicted heavy capital losses.
However counterintuitively, the prospects for bonds are a lot brighter now that yields are greater (and costs decrease).
The explanation for that is that bond yields are predictive of future expected returns. If inflation subsides to its historic norm (round 3%) then the yields quoted above would ship a bond return barely forward of its long-term average of 1.4% (actual, inflation-adjusted return).
In different phrases, bonds at the moment are priced to ship an inexpensive return for a defensive asset, at the same time as additionally they fulfil their major function as a stock market diversifier.
How issues change
Once we first wrote this text in Could 2021, bonds had delivered wonderful 10-year returns however their low yields warned of bother forward.
The desk under is a pleasant demonstration of how low yields can correlate with wonderful backward-looking returns however auger grim returns sooner or later.
This consultant fund had a horrible yield in Could 2021. However its returns over the earlier 10-years had been very good:
Vanguard UK Gov Bond Fund | Yield (%) | 10yr return (%) |
Could 2021 | 0.9 | 4.8 |
Sep 2023 | 4.5 | 0 |
Quick-forward to September 2023 and you’ll see the scenario has utterly reversed. The yield is wholesome once more however the 10-year returns are terrible (as a result of rising yields trigger bond costs to fall).
September 2023’s 0% return over ten years is the fulfilment of Could 2021’s low yield prophecy.
Boiled down, yield is one of the best information we’ve got to an intermediate bond fund’s anticipated return over the subsequent decade.
No ensures, however the asset class’s potential has largely been restored by the bond market dumping that’s burned traders – even because it causes so many to now keep away from bonds like sewage on a UK seashore.
Right here for the length
Again to our outcomes verify. You may take a look at the desk and suppose the Vanguard UK Authorities Bond Index fund is the final place you need to be. In spite of everything, it’s earned nothing for a decade. And it appears to be like worse than the remainder of the sphere throughout the opposite timeframes, too.
But the identical fund’s 10-year returns had been forward of the pack simply two years in the past! It’s table-topping efficiency then – and relegation type now – is usually as a result of longer length of its holdings.
A better length juices your holdings when bond prices rise (and yields fall) however acts as a ball-and-chain when costs fall (and yields rise).
In different phrases, there’s nothing inherently unsuitable with both of those Vanguard bond trackers. If costs rise from right here then they’ll leapfrog again up the rankings.
That makes the Vanguard pair one of the best bond fund alternative in our desk for recession safety, by the way.
However go for a shorter length fund when you suppose rates of interest can solely go up or inflation proceed to rise – or if you wish to dial down the volatility in your bond allocation, even at the price of some potential positive aspects.
Methods to examine greatest bond fund and ETF outcomes
The length concern helps illustrate why selecting your bond fund isn’t so simple as selecting the one which has scored a couple of further drops of return at a specific second in time.
A fraction of a share level makes little odds, and it doesn’t inform us which tracker will nostril forward subsequent yr or subsequent decade.
Right here’s what I’m in search of after I take a look at the efficiency desk:
- Firstly, are any of our comparable bond funds doing one thing extremely uncommon? If one product is approach forward of the remaining – or utterly off the tempo – then maybe it’s not what we predict it’s. Deviant behaviour is a cue for additional analysis.
On this occasion, the trackers are all comparatively evenly matched throughout 5 and ten years, when you consider length variations.
- I utterly ignore one-year and three-year time durations if I’ve received higher knowledge. I by no means examine funds over one-year anyway. That’s too quick to let you know something significant. Longer is healthier.
Now turning to the indices…
- Are our potential greatest bond funds a great match for his or her respective index over time? (I’ve underlined the 10-year index return rows in cyan). You’d anticipate an index tracker to barely lag its index, after prices.
If a bond tracker is a smidge forward of, or behind, its index then regardless of. But when it lags then strike it off your quick listing – begone HSBC UK Gilt Index!
You may have motive to suspect one index is inferior to a different? Then you may sweep its adherents off the desk too.
Most intermediate gilt funds comply with the FTSE Actuaries UK Typical Gilts All Shares index. The Invesco and SPDR Gilt ETFs moon after the Bloomberg Sterling Gilts Index, whereas Vanguard’s twosome chase Bloomberg’s float adjusted benchmarks.
Right here once more, the 10-year returns present that the indices are shut opponents – with the ‘float adjusted’ index’s shortfall defined by its longer length holdings.
The place does this go away us?
The candy spot is getting the mix of options you need out of your bond fund at a low value. It’s solely value factoring within the returns snapshot if one tracker appears to be like constantly superior to the remaining.
There’s no level being derailed by minuscule efficiency differentials if you’d like a UK-domiciled fund that’s out there on zero-commission coping with your dealer.
If you happen to’re particularly after a bond ETF (fairly than a mutual fund) then the Lyxor gilt tracker is grime low-cost and has edged its index over 10 years. It was second solely to the Vanguard UK Authorities Bond Index fund in 2021, too, regardless of its shorter length.
The Invesco ETF is a contact cheaper nevertheless it doesn’t have a long-term monitor document but.
The ten-year returns of the SPDR Gilt ETF look superb, nevertheless it’s twice as costly as its cheaper rivals. I’d knock it out on that foundation as a result of excessive prices are a confirmed drag issue.
Lastly, the Vanguard trackers are the way in which to go if you’d like their further length.
Greatest bond funds and ETFs – International authorities bond (GBP hedged)
Supply: Fund suppliers’ knowledge / Morningstar (A touch means knowledge not supplied).
YTM is yield-to-maturity. ‘Lux’ is Luxembourg.
The selection of worldwide authorities bond funds and ETFs has exploded since we final regarded in 2021. Prices have been slashed by new entrants and there’s even an ESG contender from UBS.
The draw back is that solely the 2 older iShares and Xtrackers merchandise have a long-term monitor document – which is why they crest the desk. The Amundi and Abrdn index trackers will notch up three yr data shortly, whereas the iShares Abroad fund solely launched in August 2023.
In the meantime, the UBS ESG effort is consigned to the underside as a result of the Swiss financial institution hasn’t but printed some very primary info. (Be aware the blanks in our desk.)
One thing additionally appears off concerning the very low yield printed by Abrdn, however that’s the determine it has given. I believe I’d fairly take the next yield from one of many different funds, contemplating they’re not exposing me to a lot (if any) extra threat.
(By the way, I’ve needed to edit the product names to suit the the desk so make certain your alternative is badged GBP hedged when you choose it out of your dealer. A few of these funds have unhedged variants however the suitable product will at all times have GBP hedged in its title.)
Now let’s do a outcomes verify earlier than speaking about why you may plump for international authorities bonds over gilts.

Keep in mind, the principle goal in evaluating outcomes is simply to verify there isn’t a bizarre outlier on the shortlist. We additionally need to see if any fund is constantly dragged down by hidden prices.
However the reality is we don’t have a lot to go on anyway as a result of a lot of the merchandise are fairly new.
What we do know is that intermediate international authorities bond funds are usually shorter length than their UK counterparts. That helps clarify why they haven’t suffered as a lot as gilt funds within the sell-off.
Properly, that and the truth that rate of interest rises have been sharper within the UK.
International authorities bonds versus gilts
Diversifying throughout international authorities bonds got here into vogue within the aftermath of the Nice Recession as many nations misplaced their cherished AAA credit score rankings – the UK amongst them.
As authorities debt balloons, many traders choose to not depend on the total religion and credit score of their dwelling nation.
Surprisingly, so-called international authorities bond funds normally maintain developed market sovereign debt solely.
However that’s truly a great factor as a result of the function of your bond allocation is to decrease your general portfolio threat. So keep away from international funds that maintain rather more risky emerging market bonds.
What concerning the underlying indexes? It’s arduous to get good info, however factsheets are on the market.
As international bond funds are about spreading your bets, it’s value understanding that the FTSE World Authorities Bond Index (Developed Markets) is probably the most diversified by nation, adopted by the JP Morgan GBI International Index, and at last the FTSE G7 Index.
On that entrance, you may ask why would you ever go for a 100% gilts fund, given the diversification advantages of worldwide authorities bonds?
Properly, you may as a result of the gilt trackers are less expensive to personal, have the next yield, and should supply marginally extra crash safety to UK traders.
However in the end that’ll all be chilly consolation if the UK state’s funds do ultimately go pop. Granted, that’s a nightmare state of affairs. But it surely’s additionally one that after appeared far much less believable than in recent times.
Don’t take forex threat
If you happen to go for international bonds then be sure to choose a fund that hedges its return to the pound. Doing so removes currency risk from the defensive facet of your portfolio, when you’re a UK-based investor.
Whereas forex threat could typically be seen as a optimistic and diversifying factor for equities, the identical just isn’t true for presidency bonds.
Foreign money change price fluctuations add volatility to your returns. Authorities bonds are there to decrease it.
Some traders go away their international bonds unhedged. However betting on change charges is a complicated transfer. It’s solely justifiable when you actually know what you’re doing.
We’ve regarded on the combined bag of proof for this ploy earlier than in a US Treasuries vs Gilts submit.
Don’t sweat the small stuff
From a giant image perspective, any of the index trackers gracing our tables of greatest bond funds (and bond ETFs) tick the suitable packing containers.
I’ve touched on a couple of key particulars to contemplate. However even these variations will possible show marginal throughout a few years of passive investing.
An important investing choice is diversifying between equities and authorities bonds within the first place.
Select a aggressive bond index fund or ETF as the principle brace of your defensive asset allocation and also you’ll be on the suitable course.
