Central Banks Broaden Gold Buying Base—A Strategic Floor for Gold Amid Volatility

The choice between gold ETFs is a secondary concern. The real story is the fundamental balance of supply and demand for the metal itself. That balance is currently in a state of tension, with powerful headwinds pushing prices down from record highs, but a resilient and broadening base of official demand providing a crucial floor.

Gold's price action in early 2026 was a classic case of a post-peak correction. The metal surged to an all-time peak of nearly $5,600 an ounce before coming under immense pressure. The catalyst was a surge in energy prices driven by the ongoing Middle East war, which sparked fears of global inflation. This, in turn, reduced expectations of lower interest rates-a scenario that directly hurts the appeal of non-yielding gold. The result was a sharp decline in investor sentiment and a move toward bear-market territory.

Yet, even as prices fell, the core driver of demand from central banks remained firm. The World Gold Council forecasts central banks to purchase roughly 850 tonnes of gold in 2026, a level essentially unchanged from 2025. This resilience is key. It shows that the strategic accumulation trend, which has seen central banks collectively add large volumes since 2020, is not easily derailed by short-term volatility. The demand is underpinned by geopolitical uncertainty, a desire to reduce reliance on the US dollar, and concerns over currency debasement.

A particularly encouraging sign is the broadening of this demand base. In January, Bank Negara Malaysia made its first net purchase of gold since 2018, while the Bank of Korea announced plans to incorporate overseas-listed physical gold ETFs into its foreign reserve portfolio for the first time since 2013. These moves signal that new central banks, or those long absent from the market, are re-engaging. As WGC's head of world banks noted, "new central banks... entering the gold market" may be a trend that continues into 2026.

The bottom line is a tug-of-war. On one side, the war in the Middle East is pressuring gold through higher real yields and inflation fears. On the other, central bank buying is holding steady at a historically strong pace, and the demand is spreading to new participants. This dynamic sets the stage for a market where price swings may remain volatile, but the underlying support from official sector demand is likely to keep the metal from a deep slide. For an investor, understanding this commodity-level balance is more important than choosing between two ETFs that track the same underlying asset.

ETF Mechanics: Cost, Liquidity, and Scale

For investors, the choice between GLD and IAU comes down to a trade-off between cost efficiency and trading convenience. Both funds are structurally identical in their core function: they are grantor trusts backed by physical gold bullion, designed to track the LBMA Gold Price with a single holding. This means their risk profiles and exposure to gold price moves are effectively the same, as evidenced by their identical beta of 0.67 against the S&P 500.

The most straightforward difference is cost. IAU charges an expense ratio of 0.25%, which is a full 0.15 percentage points lower than GLD's 0.40% fee. For a long-term investor, this gap compounds over time. While the absolute difference on a $10,000 investment is small annually, it represents a consistent drag on returns for the GLD holder. IAU is the more cost-effective option.

Size and liquidity tell a different story. GLD is the market leader, with $156.7 billion in assets under management compared to IAU's $71.4 billion. This scale translates directly into trading efficiency. GLD consistently sees higher average daily trading volume, which typically leads to tighter bid-ask spreads and less market impact for large trades. For an institutional investor or a trader executing sizable orders, this liquidity advantage is significant.

The bottom line is a classic investor dilemma. If you prioritize minimizing ongoing fees and are a passive, long-term holder, IAU's lower cost structure is a clear winner. If you value the ease of entering and exiting positions without moving the market, GLD's superior liquidity and scale are the better fit. In reality, the underlying gold market's supply-demand balance is the primary driver of returns. These ETFs are simply different vehicles to access that same metal.

The Investment Implication: Aligning ETF Choice with Strategy

The analysis of gold's supply-demand balance and the mechanics of these two ETFs now converges on a practical question: which vehicle fits your strategy? The answer hinges on whether you are a passive holder or an active trader, because their performance is a direct function of the metal's price, not the ETF structure.

For a passive, long-term investor focused on minimizing costs, IAU's lower fee is the primary advantage. The expense ratio of 0.25% versus GLD's 0.40% represents a consistent drag on returns over time. While the difference on a $10,000 investment is a few dollars annually, it compounds into a meaningful gap over a decade. Given that both funds track the same underlying asset with identical beta and nearly identical performance, the lower cost of IAU is a clear winner for someone who plans to hold the position for years.

For an active trader or institutional investor prioritizing ease of execution, GLD's superior liquidity is likely more valuable. Its massive scale-$156.7 billion in assets-translates into higher average daily trading volume and tighter bid-ask spreads. This reduces market impact for large trades and ensures you can enter or exit positions quickly without significant slippage. The recent one-year return of nearly 50% for both ETFs underscores that their returns are driven entirely by gold's price move, not the choice of vehicle. In this context, the liquidity premium of GLD is a tangible benefit for those who trade frequently.

The bottom line is alignment. If your goal is to own gold with the lowest possible ongoing cost, IAU is the logical choice. If your priority is seamless, high-volume trading, GLD's market dominance provides that advantage. Both are effective tools to gain exposure to the same commodity, but their structural differences-cost versus liquidity-make one more suitable for a specific investor profile.

Catalysts and Risks: What to Watch for the Commodity Balance

The supply-demand balance for gold is not static. Several forward-looking factors could shift the equilibrium and, by extension, the value proposition of both GLD and IAU. For investors, monitoring these catalysts is key to understanding the metal's trajectory.

First and foremost is the resilience of central bank buying. The World Gold Council forecasts official demand at roughly 850 tonnes of gold in 2026, a level that has held steady. This demand has been broadened by new participants, with the WGC noting a trend of new central banks... entering the gold market. However, this appetite could face a test. Rising geopolitical tensions, like the ongoing Middle East war, may force some nations to sell gold to bolster foreign exchange reserves. A sustained drop in official sector purchases would remove a crucial floor from the market, likely pressuring prices and undermining the strategic narrative that supports gold's long-term value.

Second, the resolution of Middle East tensions is a major potential catalyst. The current conflict has driven up energy prices, sparking inflation fears and reducing expectations for lower interest rates-a double whammy for gold. As elevated energy prices from the ongoing Middle East war sparked fears of global inflation, the metal's safe-haven appeal has been tested. A diplomatic resolution could alleviate these fears, potentially leading to a reassessment of inflation and interest rate outlooks. This would likely reduce gold's premium as a hedge, potentially limiting its upside or even triggering a re-rating lower.

Finally, the deep, liquid nature of the gold market itself is a critical factor that provides stability. The market is vast, with average daily trading volumes of approximately US$361 billion in 2025. This scale, which includes physical holdings, derivatives, and ETFs, means the system can comfortably absorb large flows. For investors in GLD or IAU, this liquidity ensures that ETF trading can move without major friction, regardless of the underlying commodity's price action. It's a structural advantage that supports the efficiency of these vehicles as access points to the metal.

The bottom line is that the commodity balance is dynamic. Watch for shifts in central bank behavior as a leading indicator of official sentiment, monitor geopolitical developments for changes in safe-haven demand, and recognize that the market's sheer size provides a buffer against liquidity shocks. These factors will determine whether gold's current tug-of-war ends in a stalemate or a decisive move.
