What is the Correlation Between Commodities and Inflation?

Commodities play an important role in financial markets and the wider economy. Prices of commodities such as crude oil, gold and agricultural products can have a direct impact on the cost of goods and services, making them closely linked to inflation.

For investors, understanding this relationship is important because rising commodity prices can contribute to higher inflation, while some commodities may also act as a hedge when inflation rises. Consumer Price Index (CPI) is one of the key indicators used to measure changes in consumer prices and track inflation.

In this article, we will look at how commodity prices and inflation are connected, what drives this relationship, and what it means for investors.

What is Inflation?

Inflation is the rate at which the price of goods rises over a period of time. Higher inflation affects the consumer’s purchasing power, negatively impacting it over time.

You can check CPI reports to know the inflation rate in an economy. Another way to measure inflation is the strength of a currency and how many goods you can buy per unit. Generally, costs increase across different sectors such as energy, food, and housing.

Inflation is caused when supply fails to meet demand, forcing sellers to increase prices, also known as demand-pull inflation. Cost-push inflation happens when production costs increase, forcing sellers to increase prices to maintain their margins.

There is another type of inflation called built-in inflation that is based on adaptive expectations. For example, workers demanding a pay rise so that they can keep up with rising costs can increase inflation rates. Monetary policies can also increase inflation.

Relationship between Commodities and Inflation

Historically, commodities have been considered to be a hedge against inflation. As inflation rises, currency values fall, but tangible assets like oil, silver, and gold either remain steady or price increase. This is because commodities are priced in fiat currencies, which can raise their costs even as currency values fall.

Why do Commodities Perform Well During Inflation?

Given below are the reasons why commodities tend to perform well during inflation:

• Increase in Demand for Physical Assets: During a rise in inflation, investors shift to commodities to protect their wealth. This causes a surge in the cost of commodities like oil, silver, gold, and agricultural products. For example, during the 2008 financial crisis, gold prices in India grew due to investors’ shift, as the yellow metal is considered a safe haven.
• Imbalance in Supply-Demand Volume: Inflation directly affects oil and agricultural product prices. Supply and demand imbalances cause production costs to rise due to increases in other expenses like transportation and rising wages. For example, low oil supply in 2026 due to tensions in the Middle East has led to demand not being met, causing fuel prices to grow.
• Carry Costs Rise: Higher inflation leads to higher interest rates, which can also increase expenses like storage costs. All of these play a role in commodity prices growing over a period of time.

When Do Commodities Not Perform Well During Inflation?

There are certain situations when commodities don’t perform well during inflation. Listed below are those situations:

• Aggressive Interest Rate Hikes: Central Banks at times may hike interest rates aggressively to counter inflation. This may cause an economic slowdown, leading to a drop in demand and causing commodity prices to fall.
• Strong US Dollar: Most commodities are traded in US dollars. An increase in the value of the dollar makes it difficult for foreign buyers to purchase commodities, leading to them being undervalued.
• Overproduction: Higher prices may lead producers to halt production, causing the rate of surplus items to crash.
• Economic Recessions: Economic recession can cause inflation to rise and demand volume to fall, which in turn could cause commodity rates to drop.
• Higher Volatility: Commodities are highly volatile. Unlike equities, it is difficult to buy and hold them for a long period of time. At times, commodity prices may drop significantly after a rise due to speculation.

How Can Different Commodities Hedge Against Inflation?

To understand the relationship between commodities and inflation, it is important to know how different commodity groups behave:

• Energy Commodities: Energy commodities like oil are not only an indicator of an inflation surge but a critical driver as well. An increase in oil prices can lead to a rise in expenses like transportation and storage costs. However, it also remains a significant hedging option, as investors can buy oil contracts and futures to lock in oil prices and maintain profitable margins.
• Precious Metals: Precious metals like gold are considered a safe haven for investors. During a high-inflation period, investors tend to turn to investing in the yellow metal to counter currency value depreciation. You can invest in gold through gold exchange-traded funds (ETFs) to protect your investment from the effects of inflation.
• Agricultural Commodities: Agricultural commodities like soybeans and wheat can highly impact inflation. They are highly volatile, and their prices can spike immediately due to changes in weather conditions, geopolitical and economic tensions. Though agricultural products can be used as a hedging option to combat short-term spikes in inflation, considering it as a long-term option is not feasible.
• Industrial Metals: Metals like copper, aluminium, and zinc are considered to be key indicators for expansionary inflation. They do well during the period when industrial demand for manufacturing is rising. These metals can be used as hedging devices during an upward economic trend when their prices are on the rise. Copper is a powerful hedge that can outperform gold during a rise in economic growth.

Conclusion

Commodities can have a complex relationship with inflation. While they can be an indicator of the rate at which inflation would grow, they also act as a hedge for investors to protect their wealth.

Commodity prices can be affected by a multitude of reasons, such as aggressive interest rate hikes by central banks and overproduction. Investors must properly analyse these conditions before making any investment-based decisions.
