Central banks, real rates, and safe-haven demand explained.
Context and background
Gold is unusual among commodities in that its price isn’t driven primarily by industrial supply and demand. It has industrial uses, but they account for a relatively small share of total demand. What moves the gold price is a mix of financial, monetary, and geopolitical forces — and the relationships between those forces and the price have shifted meaningfully in recent years, in ways worth understanding.
For investors in gold or gold-mining companies, knowing what to watch and why is more useful than simply knowing that gold tends to rise in uncertain times.
The opportunity cost of holding gold
Gold pays no interest, no dividend, and no coupon. Holding it costs money — in storage fees, insurance, or the management expense ratios of ETFs. This means that when other assets offer attractive returns, gold faces a meaningful headwind: the opportunity cost of holding something that generates no income rises as yields on competing assets rise.
This is the foundation of the relationship between gold and real interest rates, and it’s the single most important driver to understand.
A real interest rate is simply a nominal interest rate minus inflation. If a government bond yields 4% and inflation is running at 1%, the real rate is 3% — a meaningful positive return for holding a safe, liquid asset. If that same bond yields 4% but inflation is running at 5%, the real rate is negative — investors are losing purchasing power by holding bonds, and gold becomes comparatively more attractive.
The most widely watched indicator for this is the yield on US Treasury Inflation-Protected Securities, or TIPS. The 10-year TIPS yield represents the real return an investor locks in by holding US Government debt, after inflation is accounted for. Historically, the relationship between this number and the gold price has been strongly inverse: when real yields fall or turn negative, gold tends to rise, and when real yields are high and positive, gold tends to face headwinds. Between 2003 and roughly 2022, the correlation between gold and real interest rates averaged around -0.73, meaning they moved in opposite directions with considerable consistency.
That relationship has since become more complicated, which is discussed below.
The US dollar connection
Gold is priced globally in US dollars. When the dollar strengthens against other currencies, gold becomes more expensive for buyers outside the United States, which tends to dampen demand and put downward pressure on the price. When the dollar weakens, gold becomes cheaper in local currency terms for international buyers, supporting demand and price.
The historical correlation between gold and the US Dollar Index has typically ranged between -0.5 and -0.8, meaning a stronger dollar tends to coincide with lower gold prices and vice versa. Fed policy sits at the centre of this relationship — when the Federal Reserve raises interest rates, the dollar typically strengthens as dollar-denominated assets offer higher yields, and gold faces pressure from both directions simultaneously: a stronger dollar makes it more expensive internationally, while higher real yields increase the opportunity cost of holding it.
Like the real rates relationship, the USD inverse correlation has softened since 2022. During 2023 and much of 2024, gold and the dollar rose simultaneously — an unusual outcome driven by factors that ran parallel to the normal currency dynamics rather than replacing them.
Central banks: the structural shift
The most significant change in gold market dynamics over the past several years has been the emergence of central banks as dominant buyers. From 2022 to 2024, central banks purchased more than 3,200 tonnes of gold — more than double the pace of the preceding decade, and the highest sustained buying rate since records began in the 1950s.
In 2025, central bank purchases totalled 863 tonnes — below the 1,000-tonne-plus pace of the prior three years but still comfortably above historical norms, and a record 43% of central banks surveyed by the World Gold Council indicated plans to increase their own gold holdings. Gold overtook US Treasuries late in 2025 to become the world’s largest reserve asset by value — a landmark that reflects both sustained buying and the effect of rising prices on the value of existing holdings.
The motivations behind this structural shift are several. Reserve diversification — reducing dependence on the US dollar and US Treasuries as reserve assets — has been a consistent theme, particularly among central banks in Asia and emerging markets. Concerns about the long-term fiscal position of the United States and the weaponisation of dollar-denominated financial systems following Russia’s exclusion from SWIFT have accelerated this trend. Central banks’ share of total gold demand rose to nearly 25% in 2024, compared with around 12% in the 2015–19 period.
The practical effect on markets has been to put a structural floor under the gold price. Central banks are not price-sensitive buyers in the way that retail investors or ETF holders tend to be — they buy for strategic reasons and hold for years or decades, which means their demand doesn’t evaporate when prices rise. This is part of why gold continued to make new all-time highs through 2025 even as real interest rates remained meaningfully positive — a combination that, under the old framework, would have been expected to weigh on prices.
Safe-haven demand
Gold’s reputation as a safe-haven asset rests on its historical tendency to hold or increase in value during periods of economic stress, geopolitical tension, or financial market dislocation. In practice, safe-haven demand tends to be episodic rather than continuous — it surges during crises and fades as conditions stabilise.
The mechanism is straightforward. When investors are concerned about the stability of financial institutions, the value of paper currencies, or the safety of conventional assets, gold’s physical nature, lack of counterparty risk, and millennia-long track record as a store of value make it attractive as a defensive position. Major episodes of safe-haven buying have historically included the Global Financial Crisis of 2008–09, the European debt crisis of 2010–12, and more recently, the period from 2022 onward, during which the Russian invasion of Ukraine, persistent inflation, and rising concerns about US fiscal sustainability all drove demand simultaneously.
Safe-haven demand also interacts with the other drivers in ways that can temporarily override them. In 2023 and 2024, gold and the US dollar both rose together because geopolitical risk drove investors toward multiple safe-haven assets at once — breaking the typical inverse relationship between the two.
Investment demand and ETF flows
Beyond central banks, investment demand from institutional and retail investors is the other major price-sensitive driver. Global gold ETF holdings grew by 801 tonnes in 2025 — the second-strongest year on record — while bar and coin buying accelerated to a 12-year high. Safe-haven motives and portfolio diversification were the consistent themes cited by the World Gold Council.
ETF flows are a useful real-time signal for investment sentiment toward gold. When investors are adding to gold ETF positions, it reflects growing conviction that gold belongs in portfolios at current or higher prices. When ETF holdings are falling, it often indicates that rising yields or improving risk appetite is drawing capital elsewhere. Monthly ETF flow data, published by the World Gold Council, is widely followed by market participants as a leading indicator of investment demand.
Jewellery and physical demand
Jewellery remains the single largest category of gold demand by volume, accounting for roughly a third of total consumption in most years. India and China together account for the majority of global jewellery demand. Physical demand in these markets is price-sensitive over long periods — sustained high prices tend to reduce jewellery purchases — but it moves slowly and tends to act as a demand stabiliser rather than a primary price driver in the short term.
How the drivers interact
What makes gold price analysis genuinely complex is that these drivers don’t operate in isolation. In a period of high real rates and a strong dollar — the conditions that prevailed for much of 2022 and 2023 — gold would historically have faced significant headwinds. That it didn’t, and instead continued to rise to new record highs, reflects the weight of central bank buying and geopolitical risk overriding the traditional financial relationship.
The World Gold Council has noted that real interest rates were a prominent driver of the gold price for roughly a decade, but since 2022, this inverse correlation has again been counterbalanced by other factors — real rates still matter for gold’s direction over full market cycles, but they no longer operate in isolation.
The practical implication for investors is that no single indicator reliably predicts gold price movements. Real yields, the US dollar, central bank buying activity, ETF flows, and geopolitical risk all contribute, with their relative importance shifting over time. Following all of them, rather than anchoring to any one, gives a more complete picture of what’s driving the market at any given point.
Conclusion
Gold’s price is shaped by a set of overlapping financial, monetary, and geopolitical forces. Real interest rates and the US dollar have historically been the most consistent drivers, but the structural shift in central bank buying since 2022 has added a new and significant dimension to the market. Safe-haven demand, investment flows, and physical consumption round out the picture. Understanding how these drivers interact — and recognising that the relationships between them can and do change — is the foundation for interpreting gold price movements and assessing what they mean for gold-focused investments.
