VGS vs BGBL: Which International Shares ETF Should You Buy?

So which one should you buy? We compared every data point that matters.

The Snapshot

VGS wins on size, liquidity, track record, and distributions. BGBL wins on fee and has marginally outperformed since launch. The fee gap is the central question.

The Fee: 0.18% vs 0.08%

BGBL charges less than half the fee of VGS. On any portfolio, that saving is:

On $100K, the saving is $100 per year. Not life-changing. But fees compound.

Over 30 years, the 0.10% fee gap compounds to $46,000 on a $100K investment. That's real money — but it takes decades to show up.

What You Actually Own

Both ETFs hold the same types of companies — large and mid-cap stocks from developed markets excluding Australia. The overlap is enormous.

Top 10 Holdings Compared

The top holdings are effectively identical. The same mega-cap tech stocks dominate both funds. Minor weight differences reflect different index methodologies and rebalancing dates, not fundamentally different exposure.

Sector Allocation

Maximum sector difference: 0.9%. These are functionally identical portfolios.

Country Allocation

Both are roughly 72% US. If you buy either, you're getting approximately the same global developed market exposure.

The Index Difference

This is the one genuine structural difference:

VGS fully replicates the MSCI World ex-Australia index — it buys every stock in the index. BGBL uses a "sampling" approach to track the Solactive index — it holds a representative subset rather than every stock.

Why this matters: VGS's full replication means tighter index tracking. BGBL's sampling means slightly fewer holdings but also the reason BetaShares can charge a lower fee — the Solactive index licence costs less than MSCI, and sampling reduces trading costs.

In practice: The performance difference has been negligible. Over the period since BGBL launched, both have delivered virtually identical returns (+7.6% BGBL vs +7.1% VGS over 1 year, with BGBL marginally ahead).

Liquidity and Trading

VGS is 4x larger, 7x more traded, and has a tighter spread. For most retail investors, both are liquid enough — you can buy and sell millions without moving the price. But for institutional investors or very large trades, VGS's deeper liquidity matters.

The spread difference (0.03% vs 0.05%) is a hidden cost. Every time you buy or sell, you pay half the spread. Over frequent trading, VGS's tighter spread reduces costs. But for buy-and-hold investors who trade rarely, the spread is a one-time cost that's dwarfed by the ongoing MER difference.

Distributions

VGS pays quarterly, which is better for investors who want regular income or cash flow. BGBL pays at least annually — BetaShares hasn't committed to a quarterly schedule.

The yield difference (2.3% vs 1.6%) largely reflects timing — BGBL is newer and its distribution pattern is still establishing. Both funds receive the same underlying dividends from the same companies. The lower stated yield doesn't mean BGBL earns less — it retains more within the fund, which shows up in unit price growth instead.

Track Record

VGS has a 5-year track record showing +92.5% total return (14.0% annualised). BGBL has less than 3 years of live data.

BGBL's index back-test shows 14.46% p.a. over 5 years and 13.36% p.a. over 10 years — very close to VGS's actual returns. Since BGBL's inception in May 2023, it has returned approximately 18.5% p.a. vs VGS at approximately 18.3% p.a. — marginally ahead, consistent with its lower fee.

The question is whether you're comfortable with a shorter track record. The back-test data is strong and the live performance since launch closely tracks VGS. But some investors prefer the certainty of a decade-long live track record.

The Verdict

For new money, BGBL is the rational choice on fees. It charges less than half the fee of VGS, holds essentially the same companies, and has performed in line since launch. On a $100K investment over 30 years, the fee saving compounds to $46K.

For existing VGS holders, don't sell to switch. Selling triggers a capital gains tax event that likely costs more than the fee saving, especially if you've held VGS for years with significant unrealised gains. The 0.10% fee difference doesn't justify a CGT hit.

VGS still wins on:

• Liquidity (4x the AUM, tighter spread)

• Track record (10+ years live vs <3 years)

• Distributions (quarterly vs at least annually)

• Full index replication (no sampling)

• Brand trust (Vanguard is the largest ETF manager in Australia)

BGBL wins on:

• Fee (0.08% vs 0.18% — less than half)

• Unit price ($78 vs $148 — easier for DCA)

• Performance since launch (marginally ahead)

• BetaShares Direct platform (zero brokerage on BetaShares products)

The honest answer: Both are excellent funds. The differences are at the margin. If you're starting fresh and fee is your priority, buy BGBL. If you value track record, liquidity, and quarterly distributions, buy VGS. Either way, you're buying the same 1,300+ global companies at a fraction of the cost of a managed fund.

What About IWLD?

IWLD (iShares Core MSCI World ex-Australia ESG ETF) is the third option at 0.09% — almost as cheap as BGBL with an ESG screen applied. It has a longer track record (launched 2016) and 5-year return of +88.1%. Worth considering if you want both low cost and ethical screening.
