WHY INFLATION IS HURTING GOLD AND GOLD MINERS





Fast Track

Since the Iran war began this year, gold has often fallen on bad news from the Gulf. The reason is oil. Attacks on tankers in the Strait of Hormuz push up energy prices and revive inflation fears, and markets now expect the Federal Reserve to raise interest rates: a quarter-point in December and twice more in 2027. Those expected hikes have lifted real yields and the dollar, gold's two great adversaries. Gold miners have been hit harder still, because oil also raises their costs. Underneath it all sits a floor built by central banks, which have bought gold heavily since Russia's reserves were frozen in 2022. Much of the bad news is now in the price. What happens next depends on whether the Fed delivers those hikes, exceeds them or retreats from them.

Introduction

A recent market comment summed up a fear running through trading desks this autumn: a real acceleration in inflation would probably send yields back up and the dollar back up, and that could be a problem for equities. With the dollar index (DXY) already above 102, the warning carries weight.

The comment did not mention gold, yet gold has been living this scenario for months. When Iranian attacks on shipping intensify, oil jumps, inflation fears rise and gold falls. On 7 October, for example, gold slipped towards $4,100 an ounce as oil climbed and bond yields rebounded on fears that Iran was stepping up attacks on tankers in the Strait of Hormuz. A war in the world's most important oil region is pushing the classic safe-haven asset down.

This article explains that paradox. It follows the chain from an oil shock through inflation, Fed expectations, the dollar and real yields; shows why Russia's experience since 2022 has put a floor under gold that did not exist before; and traces how all of this acts, in magnified form, on gold-mining shares, using the London-listed AUCP and the US-listed GDXJ as examples. Finally, it sets out the two paths ahead.

Why It Matters

Many savers hold gold or gold-mining funds as protection against war, inflation and currency debasement. 2026 has shown that these risks can arrive together and still hurt gold: a war that raises oil prices can raise interest-rate expectations faster than it raises safe-haven demand. Investors who understand how geopolitics feeds into Fed expectations, and why markets react to surprises rather than to news itself, are better placed to judge whether their hedge will work. The same understanding explains why mining shares can fall sharply in a year when the long-term case for gold looks stronger than ever.

1. The Warning Behind the Headline

The year began with markets expecting the Fed to keep cutting rates. That expectation has been turned on its head. As of mid-October, interest-rate futures price a quarter-point increase in December and two further increases in 2027. A central bank that was expected to ease is now expected to tighten.

That reversal explains much of what has happened to gold. Expected hikes raise Treasury yields, strengthen the dollar and weigh on both equities and gold. The warning that inflation would send yields and the dollar back up has, to a large extent, already come true.

The more important point is subtler. Markets move on surprises, not on news that is already priced in. With three hikes now expected, gold's direction depends less on whether inflation is high than on whether the Fed does more, the same, or less than markets anticipate. And in 2026, the main source of that inflation is not wages or consumer spending. It is a war.

2. A War That Pushed Gold Down: Iran, Oil and the Inflation Scare

Since the Iran war began, precious-metals investors have had a frustrating time, as the conflict raised inflation expectations and projections of rate hikes. The mechanism runs through the Strait of Hormuz, the narrow channel through which a large share of the world's seaborne oil passes. Iran has demanded that vessels use approved routes, and ships taking other paths appear to have been attacked. Brent crude rose towards $102 a barrel in early October after the UK's maritime security agency counted nine attacks in the first days of the month, already half the total for all of September.

An oil supply shock of this kind is inflationary twice over: it raises fuel prices directly, then seeps into freight, food, chemicals and almost everything else. Bond markets respond by demanding higher yields. Analysts noted during the summer that rising oil was reducing demand for risk assets, and that gold was trading as one of them while Treasury yields climbed. At the worst point in July, as airstrikes on Iran intensified, gold fell back to levels last seen in November 2025, a long way below the more than $4,700 an ounce it had reached at the start of the year.

This is the central paradox of the year. War is supposed to send investors running to gold. But when the war's main economic effect is an oil shock, the inflation channel can overwhelm the safe-haven channel. The bad news from the Gulf reaches gold not as fear, but as the prospect of higher interest rates.

When war's main economic effect is an oil shock, it reaches gold not as fear, but as the prospect of higher interest rates.

3. Why Inflation Can Make the Dollar Stronger

In textbook economics, inflation weakens a currency. Over long periods this is broadly true: the theory of purchasing power parity holds that a currency losing value at home will eventually lose value abroad. Markets, however, trade the expected response of the central bank, not the long run.

When US inflation surprises upwards and the Fed is expected to raise rates, US yields rise relative to yields elsewhere. That interest-rate differential draws capital into dollar assets, and buying those assets means buying dollars. Expected Fed hikes are among the most powerful forces behind a strong dollar.

The Iran war adds two further reasons for dollar strength that have nothing to do with interest rates. First, the United States is now a net energy exporter, while the euro area and Japan import most of their oil. An oil shock therefore worsens Europe's and Japan's terms of trade far more than America's, weakening their economies and making it harder for their central banks to match the Fed. Second, in a military crisis the dollar remains the world's principal safe-haven currency.

The composition of the dollar index sharpens both effects. The DXY is about 58 per cent weighted to the euro, so it is largely a contest between the Fed and the European Central Bank. A Fed expected to hike three times, facing a euro area squeezed by energy costs, tilts that contest firmly towards the dollar. That is a large part of why the index sits above 102.

4. Gold's Real Rival: Real Yields

Gold pays no interest, no dividend and no coupon. The cost of owning it is the return given up on an interest-bearing alternative: its opportunity cost.

The alternative that matters is not the headline, or nominal, bond yield but the real yield: what a bond pays after inflation. The cleanest measure is the yield on US Treasury Inflation-Protected Securities (TIPS). When real yields rise, safe bonds become more attractive relative to gold, and gold tends to weaken. When real yields fall, gold's lack of income stops being a handicap.

A stronger dollar adds a second headwind. Gold is priced in dollars, so a rising dollar makes it more expensive for buyers paying in euros, rupees or yuan. The shift from expected cuts to expected hikes has hit gold through both channels at once.

5. Two Kinds of Inflation, Two Opposite Outcomes

Everything so far assumes the market believes the Fed will act on inflation. That assumption is the hinge of the argument.

With an oil shock, the Fed faces a genuine dilemma. Central banks traditionally look through supply shocks: higher oil prices are a one-off jump in the price level, and raising rates cannot produce more oil. Hiking into an oil shock can deepen the slowdown the shock itself causes, as the European Central Bank found when it raised rates in July 2008 and again in 2011, reversing course soon afterwards on both occasions. Yet if inflation spreads beyond energy into wages and services, ignoring it becomes dangerous.

In the first case, call it hawkish inflation, the Fed is seen to respond. It hikes, nominal yields rise faster than inflation expectations, and real yields climb. The dollar strengthens and gold falls. This is broadly what markets are now pricing.

In the second case, loss-of-control inflation, inflation stays elevated but the Fed hikes less than expected, or not at all. Political pressure, slowing growth or the rising cost of servicing a very large government debt may make higher rates too painful. Economists call that last constraint fiscal dominance: the government's finances limit what the central bank can do. Nominal yields then rise less than inflation, so real yields fall. Confidence in the dollar as a store of value erodes, and gold rallies, often sharply.

The same inflation number can therefore produce opposite results for gold, depending on the market's judgement of the central bank. This is why the 1970s, when the Fed was persistently behind the curve after two oil shocks, were a golden decade, while 1980-81, when Paul Volcker raised rates aggressively, began a long bear market in gold. The parallel with today is not exact, but the 1970s also began with a Middle East oil shock.

The same inflation figure can sink gold or launch it. What decides the outcome is whether the market still trusts the Fed.

6. Russia and the New Floor Under Gold

If gold had only the old relationship with real yields to rely on, a swing from expected cuts to expected hikes might have done far more damage. What has changed is the behaviour of the world's central banks, and the turning point was Russia.

In February 2022, after Russia's invasion of Ukraine, Western governments froze the Russian central bank's foreign reserves: roughly $300 billion of overseas sovereign assets, by Moscow's own estimate. For central banks around the world, especially those whose governments are not close allies of Washington, the message was clear. Dollar and euro reserves held abroad are only as safe as one's relations with the countries that issue them. Gold held in one's own vaults cannot be frozen by anyone.

The result was a wave of reserve diversification. Central banks in China, India, Turkey, Poland and elsewhere have bought gold at a pace not seen in decades. Even during this summer's sell-off, China's central bank reported its largest monthly addition to gold reserves in more than two and a half years in June, while bullion prices were tumbling. This official demand is largely insensitive to real yields, which is why the textbook link between gold and real yields has weakened since 2022.

Russia's own experience made the case more vividly than any argument could. According to Bloomberg estimates, the rise in the gold price since the invasion has produced gains for Russia comparable in size to the reserves frozen in Europe, and gold's share of its reserves has roughly doubled, from about a fifth before the war to over 40 per cent. European efforts to use the frozen assets to fund a loan to Ukraine failed to reach agreement. To a watching central banker, the lesson is plain: the assets held abroad were lost, while the gold at home made up for them.

There is one cross-current. Sanctions have also turned Russia from a buyer into an occasional seller. Its central bank began selling gold to domestic buyers in November 2025, and its holdings slipped to about 2,311 tonnes by early March as it swapped metal for yuan. These sales are small next to global official demand, but they show that the floor is not a guarantee.

The Russia and Iran stories meet here. Iran's war raises inflation and brings expected rate hikes, pushing gold down. Russia's precedent keeps central banks buying, holding gold up. That tug of war explains why gold has fallen this year but not collapsed.

7. Gold Miners: Leverage in Both Directions

Gold-mining shares are often treated as a substitute for gold. They are a leveraged version of it, with an extra risk attached.

The leverage comes from the structure of a miner's profits. Each ounce sells at the gold price, but costs a large part of that to produce. The industry's standard cost measure is all-in sustaining cost (AISC), and profit is the gap between the two: the margin. Because that margin is only part of the gold price, a modest change in gold produces a larger change in profits. This effect, operating leverage, explains why mining shares typically move more than the metal, in both directions (see the Deep Dive for a worked example).

The extra risk is cost inflation, and the Iran war makes it acute. Mines run fleets of trucks and generators on diesel, consume enormous amounts of electricity, and ship equipment and supplies across the world; energy is one of their largest costs. An oil shock therefore raises miners' costs at exactly the moment it pushes gold down through higher real yields. Gold, the metal, has no diesel bill. A miner squeezed between a weaker gold price and higher fuel costs suffers twice, which is what mining shareholders have experienced this year.

The reverse also holds. If gold rises faster than costs, margins widen and miners outperform the metal. A ceasefire in the Gulf would help the miners twice over: lower oil would cut their costs, and an easing inflation scare would lift gold. Investors in mining shares are betting on the margin, not simply on the gold price.

8. Juniors, AUCP and the Currency Cushion

Not all mining funds carry the same risk.

GDXJ, the VanEck Junior Gold Miners ETF, holds smaller producers and development-stage companies. These junior miners have thinner margins, higher costs and a heavier dependence on raising money to build new mines, financing that becomes dearer when rate hikes are expected. In market panics their shares are sold first: in sharp equity sell-offs such as 2008 or March 2020, miners initially fell with the stock market, because they are equities, before any safe-haven demand for gold took hold. Their one cushion is mergers and acquisitions: cash-rich major producers often buy them when share prices are depressed.

AUCP, the L&G Gold Mining UCITS ETF, is listed in London and quoted in sterling. It tracks a global index that only admits companies earning at least half their revenue from gold production; its largest holdings include Gold Fields, Kinross and Harmony. It is less volatile than GDXJ, though still far more volatile than gold.

AUCP has a feature that matters in this environment: currency exposure. Its companies are valued largely in dollars, but a UK investor holds them in pounds. When the dollar strengthens against sterling, as it tends to when Fed hikes are expected and oil is rising, the sterling value of the holdings rises, partly offsetting falls in the shares. A sterling-based investor buying GDXJ in dollars gets the same effect; an investor whose home currency is the dollar has no such offset.

Ranked by likely damage in the hawkish scenario: GDXJ suffers most, AUCP less, gold least. When the tide turns, the order reverses.

9. What to Watch

Five indicators show which way the forces are tilting:

  • Fed pricing: whether futures still show a December hike and two more in 2027. More hikes priced in is a headwind for gold; hikes priced out is a tailwind.
  • Real yields (the 10-year TIPS yield): rising is bad for gold, falling is good.
  • Brent crude and Hormuz incidents: these set the inflation impulse and the miners' fuel bill.
  • The dollar against the euro: this captures the Fed-ECB gap and Europe's greater exposure to oil.
  • Central-bank gold purchases (monthly reserve data, especially China's): these show whether the floor is holding.

10. Looking Forward: Two Paths for Gold

The starting point is a market that already expects tightening: a quarter-point hike in December and two more in 2027. Gold, the dollar and real yields already reflect much of that. The question is whether events push the Fed further than markets expect, or force it to retreat. Two broad scenarios stand out.

10.1 Scenario One: Gold Down - The Fed Delivers, and More

In this scenario, Iranian attacks on shipping persist or escalate, and Brent stays around or above $100. Energy costs pass into transport, food, rents and wages, and core inflation rises. The Fed hikes in December as expected and signals that two further hikes may not be enough. Futures begin to price a fourth hike, or a faster pace.

The economic changes follow a familiar pattern. Two-year Treasury yields rise further. Ten-year real yields climb, because nominal yields outpace inflation expectations. The euro area, a heavy oil importer, slips towards recession, and the ECB cannot keep pace with the Fed. The interest-rate differential widens, safe-haven flows add to demand for dollars, and the DXY pushes well beyond 102. Equities fall as higher discount rates reduce the value of future profits.

Gold extends its decline under rising opportunity cost and a firmer dollar, though central-bank buying, sustained by the lesson of Russia's frozen reserves, probably stops the fall from becoming a rout. The miners fare worse: lower gold prices meet higher diesel and energy bills, and margins shrink from both sides. GDXJ suffers most, as juniors face dearer financing. AUCP falls less, and for sterling-based investors the stronger dollar partly cushions the loss.

Signposts: a December hike accompanied by hawkish guidance; core inflation (excluding energy) rising; the 10-year TIPS yield making new highs; Hormuz incidents increasing; miners reporting rising all-in sustaining costs.

Gold down: Hormuz stays closed and the Fed hikes


10.2 Scenario Two: Gold Up - The Hikes Are Priced Out

In this scenario, the expected hikes fail to materialise. There are two quite different routes to that outcome.

Route A: de-escalation. A ceasefire, or a negotiated arrangement over shipping, reopens the Strait of Hormuz. Oil falls sharply, the inflation scare fades, and markets unwind the December and 2027 hikes. Real yields drop, the safe-haven premium on the dollar evaporates, and the DXY retreats. Gold recovers, and the miners gain on both fronts: a higher gold price and a lower fuel bill. This is the best case for GDXJ.



Route B: the Fed retreats. The war and high oil persist, but the Fed decides to look through the shock, or is pushed to. Growth weakens, political pressure on the central bank intensifies, and the cost of financing the government's debt at higher rates becomes a constraint: fiscal dominance. The Fed skips the December hike or signals that the tightening cycle is over, even with inflation elevated. Nominal yields rise less than inflation, so real yields fall. Breakeven inflation rates (the gap between nominal and inflation-linked bond yields) widen as investors lose confidence in the Fed's resolve. The dollar weakens even if yields stay high, a sign that trust rather than interest rates has become the driver, and foreign central banks accelerate reserve diversification.

Route B is the 1970s template and potentially the more powerful rally for gold. It is less favourable for miners than Route A, because high oil keeps squeezing their costs, but they would still rise strongly so long as gold outruns those costs.



Signposts: a ceasefire or fewer Hormuz incidents (Route A); Fed officials talking of looking through energy prices, open political criticism of the Fed, or weak demand at Treasury auctions (Route B). In both routes, watch for real yields falling and futures removing the expected hikes.

10.3 Where the Balance of Risk Lies

These scenarios need not be alternatives; they may be stages. Markets often price the hawkish response first and retreat from it only when the economic damage becomes visible, as happened with the ECB in 2008 and 2011.

One asymmetry deserves attention. With three hikes already priced, Scenario One requires the Fed to exceed expectations that are already demanding. Scenario Two requires only that it fall short of them, whether because the war ends or because the economy weakens. This is an inference rather than a forecast, but it suggests that much of gold's downside is already in the price, while a retreat from the expected hikes could come quickly and from more than one direction. For the miners, the same asymmetry applies with greater force.

Indicator Gold down Gold up
Fed path Hikes delivered, more priced Hikes priced out
Oil / Hormuz Escalation Ceasefire (A) or persists (B)
Real yields Rising Falling
Dollar (DXY) Stronger Weaker
Gold Further decline, cushioned Recovery to strong rally
Miners (AUCP, GDXJ) Fall more than gold Rise more than gold

Bottom Line

Inflation is not gold's friend by default, and neither is war. In 2026, a war in the Gulf has raised oil prices, revived inflation and turned expected Fed cuts into expected hikes, giving gold its least favourable combination of rising real yields and a strong dollar. For gold miners, the same oil shock has added a second blow by raising their costs. What has prevented a collapse is the lesson of Russia's frozen reserves, which keeps the world's central banks buying.

The question now is not whether inflation is high, but whether the Fed will follow through on the tightening markets expect. If it does, and more, gold and especially the miners have further to fall. If the hikes are priced out, whether through peace in the Gulf or a Fed unwilling to keep raising rates, the forces that pushed gold down will push it up, and the miners will move furthest. Which is more likely to give way first: Iran's grip on the Strait of Hormuz, or the Fed's resolve?

Deep Dive: The Arithmetic of Operating Leverage

Take gold at roughly today's level of $4,100 an ounce and two illustrative miners.

A major producer with an all-in sustaining cost of $1,700 an ounce:

  • Margin: $4,100 - $1,700 = $2,400.
  • Gold falls 10% to $3,690: margin $1,990, a fall of 17%.
  • Gold falls 10% and costs rise 5% (oil shock) to $1,785: margin $1,905, a fall of 21%.

A junior producer with an all-in sustaining cost of $2,200 an ounce:

  • Margin: $4,100 - $2,200 = $1,900.
  • Gold falls 10%: margin $1,490, a fall of 22%.
  • Gold falls 10% and costs rise 5% to $2,310: margin $1,380, a fall of 27%.

Route A of Scenario Two (gold up 10%, costs down 5%): the major's margin rises from $2,400 to $2,895, up 21%; the junior's from $1,900 to $2,420, up 27%.

The higher a miner's costs relative to the gold price, the greater its leverage. With gold above $4,000, margins are historically wide, so leverage is lower than when gold was $2,000, but still high enough for juniors to swing far more than majors, and both more than the metal.

The currency cushion in figures: suppose AUCP's holdings fall 10% in dollar terms while the dollar rises 4% against sterling. A UK investor's loss in pounds is roughly 0.90 x 1.04 = 0.936, or about 6.4% rather than 10%.
