The BFF Take

The gold inside these three funds is the same metal in the same kind of vault. That is the whole reason cost is the deciding factor: you are paying different fees for an identical asset. GLDM charges 0.10%, the cheapest, and on a $50,000 position that is $50 a year versus $200 for GLD. For a long-term investor holding gold as a portfolio hedge, GLDM or IAU keeps more of the return. GLD is not a mistake, but you only pay its 0.40% for a reason: it is the most liquid gold ETF with a deep options market, which active traders and large institutions need. Here is the part many investors miss: GLDM comes from State Street, the same issuer as GLD. It is the deliberately cheaper sibling built for retail buyers. If you are buying and holding, start with GLDM.

Frequently Asked Questions

What is the difference between GLD, IAU, and GLDM?
All three hold physical gold bullion in vaults, so the underlying asset is identical. GLD charges 0.40% and is the largest and most liquid. IAU charges 0.25%. GLDM charges 0.10%, the cheapest, and trades at a lower share price designed for retail buyers. GLD and GLDM are both from State Street; IAU is from iShares.
Which gold ETF is the cheapest?
GLDM is the cheapest at 0.10%, then IAU at 0.25% and GLD at 0.40%. On a $50,000 position, that is about $50 a year for GLDM versus $200 for GLD, a $150 annual gap for the same physical gold. For long-term holders, GLDM or IAU is more cost-efficient.
Why would anyone buy GLD if GLDM is cheaper?
Liquidity. GLD trades far more volume than GLDM or IAU and has a deep options market, which matters for active traders, large positions, and options strategies. For a long-term investor holding gold as a hedge, that liquidity premium is not worth the higher 0.40% fee, and GLDM or IAU serve better.
Is GLDM the same as GLD?
They hold the same physical gold from the same issuer, State Street, but they are separate funds. GLDM launched in 2018 as a lower-cost, lower-share-price version for retail investors at 0.10% versus GLD’s 0.40%. The trade-off is that GLDM has less trading volume and a smaller options market.
How are gold ETFs taxed?
In a taxable account, gold ETFs that hold physical bullion are generally taxed as collectibles, with a maximum long-term capital gains rate of 28%, higher than the rate on stocks. This applies to GLD, IAU, and GLDM equally. Holding them in an IRA can avoid that higher rate. Tax treatment varies by situation. This is general information, not tax advice.
