On Wednesday, 14 October, the United States will publish its September Consumer Price Index, a report that tells us how fast prices rose over the past year. Gold traders are treating it as the most important data release before the US central bank meets on 28 October. Gold closed last Friday at $4,193.60 per ounce after a strong bounce from a two-month low. This guide explains what the report is, what numbers analysts expect, and why gold reacts to it.
What the consumer price index measures
The Consumer Price Index tracks the cost of a typical basket of goods and services, such as petrol, groceries, rent, airfares, and used cars. When the index rises 3.6% over twelve months, a basket that cost $100 a year ago now costs $103.60. Governments and central banks use it to judge whether inflation is under control.
There are two versions. Headline inflation includes everything, even food and energy. Core inflation leaves out food and energy because those prices swing sharply from month to month. Central bankers watch the core figure closely, since it shows underlying trends that are less affected by sudden jumps in oil.
What analysts expect
According to Admiral Markets' preview, August headline inflation was 3.4% and core was 2.4%. For September, forecasters expect headline inflation of about 3.6% to 3.7%, mainly because petrol prices hit a record last month. The consensus figure is 3.7%, and the Cleveland Fed's estimate is 3.60%. Core inflation is expected to hold near 2.4% for the year, or about 0.2% for the month, with airfares, hotels, and used cars as the main wild cards.
Brent crude oil closed at $104.28 on 8 October, and US regular petrol averaged $4.36 per gallon. That explains why the headline number is expected to rise while the core number stays steady.
Why gold cares about inflation data
Gold pays no interest. When the Federal Reserve raises interest rates to fight inflation, savings accounts and government bonds pay more, and gold looks less attractive by comparison. When inflation cools, the Fed has less reason to raise rates, and gold often benefits.
The Fed raised its target range to 3.75% to 4.00% on 16 September. Odds of another increase on 28 October fell from about 70% in late September to about 26% by 7 October, though a December increase is still largely expected. Government bond yields have been climbing too. BabyPips reported that the 10-year Treasury yield reached its highest level since 2002 last Wednesday. Those high yields have been the main weight on gold this autumn.
Three possible outcomes on Wednesday
Admiral Markets sketches three illustrative scenarios. In a hot scenario, core inflation rises 0.3% or more for the month. Odds of an October rate hike could jump, yields could climb back toward the 5.31% level reached on 5 October, and the dollar could strengthen. That combination usually pressures gold.
In an in-line scenario, headline inflation lands near 0.5% for the month and core near 0.2%. The market reaction could be mixed and short-lived, with attention shifting to details such as shelter costs. In a soft scenario, core inflation rises 0.1% or less. Hike odds could fall, yields could ease, and the dollar could weaken—all of which tend to support gold. These are illustrations rather than forecasts, and real market reactions can differ.
Where gold stands going in
Gold's midweek low was its weakest since 5 August. The rebound on Friday was 1.48%, taking spot gold to $4,193.60 inside a $4,130.10 to $4,208.10 range, as shown in Guardian Gold's market update. Weak US consumer sentiment of 46.3 and softer bond yields after a solid Treasury auction helped. According to Admiral Markets, gold was down about 4.5% for the year as of 8 October, and one analyst cites a technical downside target near $3,920. The record high of $5,598.58 was set in late January, so the metal still trades about 25% below it. You can follow the live price on Trading Economics.
Other dates this week
Producer prices and retail sales are due on Thursday. On Friday, Fed Chair Kevin Warsh is scheduled to speak early in the day. Traders will be looking for hints about whether the Fed intends to raise rates again before the end of the year.
What this means if you are shopping for gold jewellery
Few people buying a ring or a bracelet will change their plans because of one inflation report. Still, knowing the calendar helps. If you are watching the price, expect larger swings on Wednesday and Friday. If you are not in a hurry, you may prefer to wait until the data is out and the market has settled.
Some simple checks apply whatever the price does: compare the price per gram with the day's gold price, ask how the workmanship charge is calculated, check the purity mark, and keep the receipt. Lightweight pieces use less gold, so a market swing changes their final price by a smaller amount than it would for a heavy chain.
The main point is that headline numbers are only part of the story. Expectations matter as much as results, so a report that comes in slightly above or below forecast can move the price even when the figure itself looks ordinary. Reading the preview before the data arrives makes the reaction easier to follow.
