Investing in the stock market often requires significant capital, which may not always be readily available. While borrowing from banks, friends or family is an option, it can sometimes feel inconvenient or uncomfortable. This is where collateral margin allows you to leverage your existing assets to access additional funds for trading without liquidating your current investments.  

Collateral margin allows you to pledge your securities such as stocks, mutual funds or bonds as collateral with your broker. In return you receive a margin balance enables you to take new trading positions while keeping your existing holdings intact. This offers a smart way to expand your investment potential without requiring fresh capital.

However, while collateral margin enhances your buying power, it also comes with risks like market fluctuations and margin calls, which traders should be mindful of. This article explores everything you need to know about collateral margin how it works, its benefits, potential risks and a step by step guide to using it efficiently in your trading journey.

What is Collateral in Margin Trading?

Collateral in margin trading also called margin against shares, refers to stocks, mutual funds, bonds or other securities pledged to a broker in exchange for a margin loan. This enables you to trade beyond your actual cash balance.
By pledging your investments, you receive a margin limit, which dictates how much you can borrow. If your trade results in a loss and you cannot repay, the broker can sell your pledged securities to recover their funds.

Types of Acceptable Collaterals

If you want to trade using the Margin Trading Facility or MTF, you must pledge certain financial securities as collateral. However not all investments are eligible only specific types of securities are accepted. Here’s a look at some of the most commonly used collaterals in MTF trading.

Cash is the simplest and most commonly accepted form of collateral. Brokers prefer it because it provides immediate liquidity and carries no risk. Using cash as collateral helps absorb market fluctuations and lowers the risk of margin calls.

You can use stocks as collateral to get a loan for more investments if you own stocks. The loan amount depends on the market value of your shares but brokers reduce this value by a certain percentage, known as a ‘haircut.’ This reduction varies based on factors like how easily the stock can be sold, its price fluctuations and the overall risk involved. 

Government issued bonds are considered stable collateral because they carry lower risk. The margin offered against these bonds is usually a percentage of their market value which depends on factors like their maturity period and credit rating.

You can also use mutual fund units as collateral particularly diversified equity and debt funds. However, since mutual funds are affected by market fluctuations, they usually have a higher haircut percentage than stocks or bonds.

Some brokers let you pledge ETFs as collateral. Since ETFs hold a mix of securities, they offer diversification benefits. However the haircut applied depends on the type of assets they contain and how volatile they are.

Importance of Collateral Margin

Collateral margin is a good option for investors looking to borrow for investments. It allows them to access higher margin limits without extra costs while also giving brokers a layer of security during market fluctuations. This makes it valuable for both investors and brokers.

How Does Collateral Work in Margin Trading?

Before using your assets as collateral in margin trading, it’s important to understand how the process works. Here’s a breakdown:

When you pledge assets as collateral broker lends you funds based on its loan-to-value or LTV ratio. It means they provide only a certain percentage of the asset’s market value instead of the full amount. It helps them manage risks and reduce potential losses. If the market fluctuates and the value of your collateral drops, the broker may ask you to provide additional funds or assets to maintain the required margin.
As a trader, you can use margin trading to leverage your existing assets and invest more in the market. Instead of letting your holdings sit idle, you can borrow against them to increase your investment power. This is especially helpful if you don’t qualify for traditional loans. And you still retain ownership of the pledged assets allowing you to diversify your investments while using margin funds.

How To Calculate Collateral in Margin Trading?

Suppose you have a portfolio worth ₹8,00,000, consisting of stocks that qualify as collateral. Brokers set a margin ratio based on the type of pledged securities. Suppose your broker allows an 80% margin ratio meaning you can borrow up to 80% of your portfolio value.

Calculation:

  • Portfolio value: ₹8,00,000
  • Margin ratio: 80%
  • Maximum borrowable amount: ₹6,40,000

It means you can borrow up to ₹6,40,000 to trade beyond your available funds. Now, you can use this margin to buy more stocks, derivatives or other securities. However, this is borrowed money, so you must be cautious.

Interest on the Borrowed Amount

Brokers charge interest on the borrowed amount. Suppose the interest rate is 12% per year. If you borrow the full ₹6,40,000 and hold it for a year, you’ll have to pay:

  • Interest Calculation: ₹6,40,000 × 12% = ₹76,800 per year.

Some brokers charge interest daily or monthly, so it’s important to check their terms before using margin.

If Portfolio Value Changes:

Your margin limit isn’t fixed it fluctuates with the value of your pledged securities.

Scenario 1 (If your portfolio value increases)

Suppose your portfolio grows to ₹10,00,000. With an 80% margin ratio, your new margin limit will be:

  •  ₹10,00,000 × 80% = ₹8,00,000
  •  Now, you can borrow up to ₹8,00,000.

Scenario 2 (If your portfolio value decreases)

If your portfolio drops to ₹7,00,000, your margin limit also reduces:
₹7,00,000 × 80% = ₹5,60,000

If you’ve already borrowed ₹6,40,000, this drop means you exceed your margin limit. Your broker may issue a margin call, requiring you to:

  • Deposit additional funds to maintain the margin
  • Sell some of your holdings to cover the shortfall

Managing Collateral Effectively  

Managing collateral properly helps you avoid unnecessary losses and ensures smooth margin trading. Here’s how you can do it:  

Value of your pledged assets keeps changing due to market fluctuations. If the value drops, you may receive a margin call from your broker asking you to add more funds. If you fail to do so, your positions might be liquidated. Regularly monitoring your pledged assets helps you stay prepared and maintain the required margin without disruptions.
Each broker has different rules regarding margin trading such as which assets can be pledged, margin interest rates, how margin calls work and required maintenance levels.  By staying proactive and informed you can manage your collateral efficiently and minimise risks in margin trading.
