IAU Returned 42% in a Year of Sticky Inflation. Here’s Why Allocators Are Reconsidering Gold

Gold has done exactly what its defenders promised over the past year, and the numbers explain why allocators are revisiting the metal as a real portfolio building block. iShares Gold Trust (NYSEARCA:IAU | IAU Price Prediction) returned 42% in the twelve months through May 1, 2026, a stretch that overlapped with sticky core inflation, three Federal Reserve rate cuts, and a brief VIX spike to 31.05 in late March. For investors weighing whether physical gold deserves a permanent seat in the portfolio, IAU is the cleanest, cheapest way most retail accounts can take that exposure.

What IAU Is Built to Do

IAU is a grantor trust that holds allocated gold bullion in vaults. Each share represents a fractional claim on physical metal, so the price tracks the spot gold market minus the trust’s expense ratio, which iShares lists at 0.25%. There is no operating business, no dividend, and no derivative overlay. The return engine is simply the gold price.

The portfolio role is narrower than most equity ETFs. Gold is held to do three things: hedge against currency debasement and unexpected inflation, provide a low-correlation ballast when stocks fall, and act as crisis insurance when geopolitical or financial stress sends investors toward hard assets. The macro backdrop has been supportive on all three fronts. Core PCE sits at the 90.9th percentile of its twelve-month range, CPI is at the 90th percentile, and the Fed Funds upper bound has fallen from 4.5% to 3.75% over the past year. Lower nominal rates with persistent inflation compress real yields, which historically supports gold.

Strategy Execution and Returns vs. Alternatives

IAU has delivered on its mandate. Over five years it returned 157%, and over ten years 249%. Compared with SPDR Gold Shares (NYSEARCA:GLD), IAU’s larger competitor, the gap is small but real: GLD returned 155% over five years and 244% over ten. The cumulative difference is the lower expense ratio compounding quietly in IAU’s favor.

The honest comparison is against equities. The S&P 500 has historically outpaced gold over most rolling decades, and an investor who put 100% into stocks rather than gold over the past ten years almost certainly fared better. Gold’s value shows up in sequence and correlation, in the years when stocks fall and the metal does not. The recent 31.05 VIX print and the 10-year Treasury yield sitting near a 12-month high at 4.40% highlight why diversification matters: stress events are not predictable, and gold often pays off precisely when everything else hurts.

The Real Tradeoffs

1. Zero yield. IAU produces no income. In a world where 10-year Treasuries pay 4.40%, the opportunity cost of a large gold sleeve is meaningful. Every dollar in IAU is a dollar not earning interest, dividends, or business cash flow.
2. Collectibles tax treatment. Because IAU holds physical bullion, the IRS taxes long-term gains as collectibles, with a maximum rate of 28% rather than the standard 15% or 20% long-term capital gains brackets. Holding it inside an IRA neutralizes this; holding it in a taxable account does not.
3. Volatility without a business behind it. Gold corrects sharply. IAU dropped 3.3% in the past month alone. There are no earnings, buybacks, or dividends to cushion drawdowns, only the spot price.

IAU fits best as a 5% to 10% strategic sleeve for investors who want a non-correlated hedge against inflation and equity drawdowns and accept that the position pays no income. The primary risk is opportunity cost: a sustained period of rising real yields and calm markets is exactly the environment where gold lags everything else in the portfolio.
