What is Basis Risk?

The price difference between a hedged asset and the hedging instrument changes unexpectedly. It also plays a significant role in market risk in capital markets. This unexpected change is identified as the basis risk. The " basis unexpectedly” is the difference between:

• Spot Price of the asset
• Futures Price of the hedging contract

When this difference changes unexpectedly, basis risk arises. Basis risk can reduce the effectiveness of a hedging strategy and may result in financial losses. It is very common in futures contracts and derivative markets.

Basis Risk Formula

Below is the formula for basis risk:

Basis = Spot Price - Futures Price

Where:

• Spot Price = Current market price of the asset
• Futures Price = Price of the futures contract

The basis changes over time depending on market conditions. If the basis changes unexpectedly, the hedge may not work perfectly. The basis risk also persists in the e-commerce market because the fluctuations impact it severely.

Key Components of the Basis Risk Formula

Understanding the components of basis risk helps students analyse how hedging works in real financial markets. Below are significant components that help the financial market conditions.

Spot Price

The current market price is based on the asset that can be bought or sold, which is identified as the spot price. Examples include:

• Current gold price
• Current crude oil price
• Current currency exchange rate

Spot prices fluctuate continuously based on market demand and supply. It also reflects the market positioning, reflecting the asset pricing.

Futures Price

The futures price refers to the agreed price of a futures contract for delivery at a future date.Futures prices are influenced by:

• Market expectations
• Interest rates
• Storage costs
• Economic conditions

Changes in futures prices directly affect basis calculations.

Basis Movement

Basis movement refers to changes in the difference between spot and futures prices. A stable basis helps hedging strategies work effectively. Unexpected basis changes increase hedging risk.

Common Causes of the Basis Risk

Several factors may create basis risk in financial markets. Below are some of the reasons due to which basis risk takes place. It also contributes to the value proposition in the market, which is significant for risk management in businesses.

Location

Location differences can create basis risk when the asset and hedging instrument belong to different geographical markets.Transportation costs and local demand influence these differences.

Here are some examples:

• In different countries, oil prices
• In a different region, agricultural commodity prices vary

Quality

Quality differences between the hedged asset and the futures contract may create basis risk. Below are some examples:

• Variations in agricultural product quality
• Different metal purity standards
• Different grades of crude oil

If the actual asset differs from the hedging contract specification, price movements may not match perfectly.

Timing

Timing mismatches also create basis risk. This happens when:

• The hedge expires before the actual transaction date
• Market prices change during the gap period

Timing differences are common in futures and derivative markets.

Market Conditions

Volatile economic conditions may increase basis risk. Factors include:

• Political instability
• Supply disruptions
• Interest rate changes
• Inflation

Real World Example of the Basis Risk Formula

A wheat producer wanted to hedge against the decreasing wheat prices. The farmer observes the following aspects of their business:

• Current Spot Price = ₹2,000 per quintal
• Future Prices = ₹1,950 per quintal

The implementation of the formula is below:

Basis = 2000 - 1950 = 50

So, the basis is ₹50.

Now, assume market conditions change unexpectedly.

Later:

• Spot Price falls to ₹1,850
• Futures Price falls to ₹1,830

New basis risk calculation is:

Basis = 1850 - 1830 = 20

The basis changed from ₹50 to ₹20.

This unexpected change affects the effectiveness of the hedge and creates basis risk.The farmer may not receive the expected level of protection.
