The dynamic delta hedging model I developed for Asian Paints protected the company from volatile Brent Crude prices by automatically adjusting futures positions. It minimized risks, lowered operational costs, and provided strategic insights. Scalable across industries, the model helped ensure a stable cost structure and optimized financial decision-making.

Introduction
Delta hedging is a widely used strategy in the financial world for managing risk, particularly in options trading. The dynamic delta hedging model developed in this project serves a specific business need: to protect Asian Paints from the volatile prices of Brent Crude, a crucial raw material in the paint manufacturing process. Asian Paints, like many other businesses dependent on commodities, is significantly affected by fluctuating oil prices, as crude oil derivatives form a large part of its raw materials. The volatility of oil prices can drastically impact the company's cost structure and profitability.
In this project, I built a Python-based delta hedging model that provides real-time dynamic hedging against Brent Crude's price fluctuations. The model dynamically adjusts the number of futures contracts needed to hedge Asian Paints' exposure to oil prices. By automating this process, the model ensures that the company maintains an optimal hedging position, minimizing the impact of price volatility.
Overview of Delta Hedging
Before delving into the specifics of the dynamic model, it’s essential to understand delta and delta hedging. Delta refers to the sensitivity of the price of an option to changes in the price of the underlying asset (in this case, Brent Crude). The delta value ranges between -1 and 1, representing how much the option price will change for a unit change in the price of the underlying asset.
Delta hedging involves adjusting the position in the underlying asset to ensure that the portfolio remains neutral to changes in the asset price. In essence, delta hedging seeks to create a position where gains or losses in one part of the portfolio are offset by corresponding losses or gains in another. This strategy is particularly useful for managing short-term price movements.
How the Dynamic Delta Hedging Model Works
My model is built in Python and utilizes real-time Brent Crude prices to compute the delta of Asian Paints' oil options. Using the Black-Scholes formula, the model calculates the delta value for the options position. The model then determines the optimal number of futures contracts Asian Paints should hold to maintain a delta-neutral portfolio, mitigating the risk posed by fluctuations in oil prices.
Key Components of the Model
Black-Scholes Formula for Delta Calculation: The Black-Scholes model is used to calculate the delta of options on Brent Crude. The formula takes into account factors such as the spot price of oil, the strike price of the option, time to maturity, volatility, and the risk-free rate.
Delta (Δ): Delta measures the rate of change of the option's price with respect to the underlying asset’s price. For a call option, delta ranges from 0 to 1, whereas for a put option, it ranges from -1 to 0.
Real-Time Brent Crude Price Integration: The model fetches real-time data for Brent Crude prices from an external API to ensure that the hedging strategy remains current with market conditions. This real-time pricing data is fed into the delta calculation, allowing the model to adjust the hedging strategy dynamically.
Hedge Ratio Calculation: The hedge ratio is determined by multiplying the delta by the number of options held. This gives the number of futures contracts required to hedge the exposure effectively. If the delta changes, the model dynamically adjusts the hedge ratio, ensuring the portfolio remains delta-neutral.
Hedge Ratio: This is the ratio of the number of futures contracts to the number of options, ensuring that the portfolio is protected against adverse movements in the price of Brent Crude.
Graphical Visualization: The model provides a visual representation of the relationship between Brent Crude prices and the delta values. This graph helps users understand how the delta changes as the price of the underlying asset fluctuates, enabling more informed decision-making.
Automatic Updates: The model is designed to update every few seconds, recalculating the delta and hedge ratio based on the latest Brent Crude price data. This ensures that the hedge remains optimal at all times, regardless of price movements.

Usability and Applications for Asian Paints (My approach to their problem)
The primary objective of this model was to help Asian Paints protect itself from the unpredictable swings in Brent Crude prices. By utilizing dynamic delta hedging, the company was able to maintain a more stable cost structure and protect its margins. The model allowed for the automatic adjustment of futures positions, meaning that the hedging process became less labor-intensive and more responsive to real-time market conditions.
The usability of this model extended beyond Asian Paints and could have been applied to any company with significant exposure to commodity price volatility. Its dynamic nature meant that it could be applied across various industries, such as airlines (for fuel hedging), agriculture (for crop price hedging), or even metals and mining companies (for hedging raw materials like copper or aluminum).
Key benefits of the model for Asian Paints included:
Risk Mitigation: By maintaining a delta-neutral position, the company effectively minimized the risks associated with sharp increases or decreases in oil prices.
Cost Control: The automated nature of the model ensured that the company didn’t have to manually track oil price movements or adjust its hedge frequently, thus lowering operational costs.
Strategic Insights: The visual representation of delta movements helped decision-makers understand the correlation between oil prices and the company's exposure, allowing them to make more informed strategic decisions.
Scalability: The model was scalable, meaning that it could be adapted to hedge multiple commodities or different options structures, depending on the company’s exposure.
Summary of Key Terms
Delta: A measure of how much the price of an option changes with respect to changes in the price of the underlying asset (Brent Crude in this case).
Delta Hedging: A strategy used to mitigate risk by holding positions in the underlying asset (or futures) that offset the changes in the option’s price.
Hedge Ratio: The number of futures contracts required to hedge a position effectively.
Brent Crude: A major benchmark for global oil prices, affecting industries like paint manufacturing.
Black-Scholes Model: A mathematical model used for pricing options, which also provided the delta used in this hedging strategy.
I'm in no terms a master programmer, this is a very basic idea and its implementations (but we gotta start somewhere know..), there is a huge scope of improvement, so much so that I will not be listing it this time rather in future would publish better projects exploring more complex techniques and ideas. Cheers!
