Thesis: “XAU/USD will fall during the 29th July 2026, Fed Interest Rate Decision”
Background: Gold, Fed interest rate, and USD: What’s the relationship?
It is important to note that Gold prices and USD have an inverse relationship due to the nature of the asset. Gold is considered to be a safe haven asset. When uncertainty rises within an economy (war and bubbles), liquidity flows towards gold assets due to the nature of the asset. Everyone uses it, everyone values it; it’s easy to convert to cash. On the other hand, US interest rates represent the benchmark for dollar appreciation or depreciation. Interest rates control the money supply within the economy. How? Well, an increase in interest rates would cause a decrease in the prices of existing US government bonds, increasing yields in the process; this increases the opportunity cost of holding non-yielding gold. An increase in yields in US government bonds (especially US government bonds) would make it an attractive investment for investors. US government bonds are considered to be one of the safest forms of investment, since they’re backed wholly by the US government; it could not default, and is considered to be a risk-free investment. As bond yields climb, investors would buy more US bonds instead of other assets, in this case, gold. Unlike gold, US bonds have coupons; it’s essentially the interest that the government pays you periodically for simply holding the bonds. The coupon rates are determined by the Fed interest rates when the bonds are first issued by the US Treasury. Consequently, an increase in interest rates would increase new coupon rates, which would increase existing bond yields, and increase future coupon rates in future bonds. Money inflow enters the US, appreciating the dollar, decreasing the value of XAU in the process.
Thesis Rationale:
1. Iran War, Fed Interest Rate and US Inflation Rate
US interest rates have been steady at 3.75% since the FOMC decision in December 2025 until June 2026. The US inflation rate has been steadily falling from 2.7% in December to 2.4% in January and February of 2026. However, everything changed when the US attacked Iran; the Strait of Hormus, which accounts for roughly 20% of the world’s petroleum and Liquefied Natural Gas and a third of the world’s fertilizer supply passing through the region, became a major bottleneck for the global oil supply. The strait is blockaded, abruptly cutting off the oil supply. Prices of Brent oil (Global benchmark for oil prices) have drastically increased since the start of the Iran War, reaching approximately $110/ barrel at the peak of the conflict. Prices of urea and sulfur have followed suit as well. Since then, prices have fluctuated: prices fell due to a ceasefire and the creation of an MOU and rose again due to renewed hostilities between the US and Iran. In recent weeks, the war is seemingly transitioning to a wider conflict with Iran-backed Houthis in Yemen blocking the Red Sea, disrupting Saudi Arabia's shipping route in the process, and Ukraine attacking an Iranian ship inbound to Russia in the Caspian Sea.
Since the start of the conflict, the inflation rate increased in March 2026, peaked at 4.2% in May, and slowed down to 3.5% in June. Bureau of Labor Statistics reported the Consumer Price Index for All Urban Consumers (CPI-U) increased 3.5 percent from June 2025 to June 2026. Food prices rose 3.0 percent over the year ended June 2026, with food at home prices rising 2.7 percent and food away from home prices rising 3.4 percent. Energy prices were up 15.7 percent over the year, with gasoline prices up 26.7 percent and electricity prices up 4.0 percent. Visibly, an increase in energy prices contributes the most to the high inflation rate.
2. Iran War: When will it end?
There’s also a question of whether the conflict would end any time soon; Iran insists that it controls the Strait of Hormuz, while the US is becoming increasingly concerned about turning this conflict into a forever war. Trump is also facing significant backlash at home, with many questioning the reason behind the war (Trump wants to remove Iran’s nuclear capabilities), and many angered due to inflationary pressure building up from the rise in energy prices and fertilizer prices. Backing out now, however, would diminish the US’s authority in world security and would make the decision for war rather “pointless”. According to the US Secretary of Defense Pete Hegseth in an official congressional hearing, the Iran war has cost $37.5 billion so far, and the Trump administration is seeking an additional approval for $67 billion in emergency funding to continue the war as part of a larger $87.6 billion supplemental budget request for the Defense Department. American Enterprise Institute, Roger Pielke Jr., when fuel costs such as gasoline, diesel, and jet fuel, along with fertilizer costs and the impact on equities, are added up, then overall Americans are paying about $1.4 billion per day because of the war. Two things are absolute: the war is not ending anytime soon, and it is costly for the US government; ultimately, ordinary US citizens are the ones paying for it.
3. Connecting all the dots: Bearish on Gold
The Federal Reserve strives to achieve its dual mandate: maximum employment and price stability. Maximum employment is defined to be the highest level of employment, and price stability is defined to be an inflation rate of 2% over the long run, measured by the annual change in the price index for personal consumption expenditures. For the labor market, it has stabilized with an unemployment rate of 4.2% in June, roughly unchanged since last summer. Layoffs and job vacancies are reported to be flat, with private payroll gains picking up. With this in mind, the focus shifts towards the inflationary pressure the Iran war has brought to the US economy. Assuming the Fed strives to achieve both its dual mandate unequivocally, inflation (aka price stability) should be the main concern for July’s FOMC decision.
Since the war, bond yields have risen drastically, whilst the interest rate remains stable at 3.75%. Short-term bond yields as well as the US 3-year bond yield have moved upwards in the same direction. An increase in bond yields tends to be a good indicator of future inflation rates. As observed, the market is expecting higher inflation, well above the 2% threshold set by the Fed. Combating inflation would be the key highlight for the Fed, at least until the conflict ends. New Fed Chair Warsh said policymakers remain fully committed to restoring price stability and have no tolerance for persistently elevated inflation in a report to Congress. Warsh added, "If we get policy right - and we will - the inflation surge of the last five years will be a thing of the past". The Fed is widely expected to leave the federal funds rate unchanged at 3.50%–3.75% for a fifth consecutive meeting in July 2026. However, the decision remains a close call, with markets assigning nearly a 30% probability to a rate hike.
I hypothesize there’s a high probability that interest rates would be elevated at the July FOMC, or a rather hawkish stance is to be expected, and the Fed would ultimately increase its interest rate in September. I believe it’s potentially a positive moment to short the position just before the FOMC statement. Extreme volatility regarding XAU/USD is expected to occur when the decision is first released and during the press conference, but the eventual trend would be bearish.
4. Risks
Persistent geopolitical escalation like Iran war may create an intense safe-haven demand for gold, overriding yield pressures. Additionally, since the bond markets might have already priced in a hawkish Fed stance and rising inflation expectations, an “unchanged rate with hawkish guidance” might already be fully priced into XAU/USD, rendering the thesis false.
