Security

Security — Meaning, Definition & Full Explanation

A security is a tradable financial instrument that represents a claim on assets or future cash flows and carries a specific monetary value. Securities are issued by corporations, governments, and other entities to raise capital from investors, and they are held in electronic (dematerialised) form in India. The three main categories are equity securities (ownership stakes), debt securities (borrowing obligations), and hybrid securities (combining features of both).

What is Security?

A security is a standardised financial asset that can be bought, sold, and transferred in capital markets. It represents either ownership in a company, a loan extended to an issuer, or a combination of both. Each security has a defined face value (also called par value or nominal value) and is recorded electronically in dematerialised accounts rather than as physical certificates.

Securities exist because companies and governments need capital to fund operations, expansion, and development, while investors seek returns on their surplus funds. By issuing securities, an entity can raise large sums without relying on banks alone. Securities are regulated instruments—meaning their issuance, trading, and disclosure are governed by law to protect investors from fraud and ensure market transparency. The key advantage is liquidity: unlike a bank deposit locked in for a term, securities can often be sold quickly in public markets. Securities also diversify an economy's financing options beyond traditional lending.

How Security Works

The lifecycle of a security involves several stages:

1. Issuance: A company or government decides to raise capital. It prepares an offering document (prospectus) and seeks regulatory approval from SEBI (for companies) or the RBI (for government securities).

2. Pricing and Sale: The issuer sets a price (or underwriters determine a price band for an IPO) and sells securities to institutional and retail investors. Sale can be public (open to all) or private (to selected investors).

3. Registration and Dematerialisation: Once bought, the security is credited to the investor's demat account (a digital holding), eliminating physical certificates. The depositories (NSDL or CDSL in India) maintain these electronic records.

4. Trading: The investor can hold the security or sell it on a stock exchange (NSE or BSE) to another buyer. Trading happens continuously during market hours.

5. Cash Flows: Depending on the security type, the issuer pays dividends (equity), interest (debt), or both (hybrid) to the holder.

6. Maturity or Exit: Debt securities mature on a set date when the issuer repays principal. Equities have no maturity and can be held indefinitely or sold.

Securities can be secured (backed by collateral) or unsecured (backed only by the issuer's creditworthiness). They can also be traded on exchanges (listed) or privately negotiated (unlisted).

Security in Indian Banking

In India, securities are regulated by the Securities and Exchange Board of India (SEBI) under the Securities Contracts (Regulation) Act, 1956. The RBI regulates government securities and treasury bills. Banks themselves are significant investors in and dealers of securities.

Equity securities are issued through Initial Public Offerings (IPOs), Further Public Offerings (FPOs), and rights issues. Companies listed on the NSE and BSE (like TCS, HDFC Bank, or Reliance) have issued equity securities. SEBI mandates disclosure norms, lock-in periods, and underwriting standards to protect retail investors.

Debt securities include corporate bonds, debentures, and government securities (G-Secs). The RBI issues securities on behalf of the Government of India to finance the fiscal deficit. Banks hold large portfolios of government securities as part of their Statutory Liquidity Ratio (SLR) requirement—currently set at 18% of net demand and time liabilities (NDTL).

Hybrid securities are less common but growing; examples include preference shares, which combine dividend payments (like debt) with equity-like characteristics.

For banking exam candidates (JAIIB/CAIIB), understanding security types, their risk profiles, and regulatory frameworks is core syllabus material. The RBI's monetary policy operates partly through Open Market Operations (OMOs) involving government securities, making them essential to banking professionals' knowledge.

Practical Example

Amit Kumar, a 35-year-old IT professional in Bangalore, decides to diversify his savings. He opens a demat account with HDFC Securities. In January 2024, he invests ₹2,00,000 in five different securities: (1) 100 shares of HDFC Bank at ₹1,600 each (equity security), (2) ₹50,000 in a 5-year corporate bond issued by Reliance Industries at 7% annual interest (debt security), (3) ₹30,000 in government securities (G-Secs) maturing in 10 years, (4) ₹20,000 in a preference share (hybrid security), and (5) ₹5,000 left as cash.

Six months later, HDFC Bank's share price rises to ₹1,750, and Amit receives his first interest payment of ₹3,500 from the Reliance bond. He logs into his demat account and sees all securities listed electronically. He decides to sell 50 shares at ₹1,750 on the NSE, realising a ₹7,500 gain. The sale settles in T+1 (next business day), and the proceeds are credited to his account. This example shows how securities function: they are issued, held electronically, traded, and generate returns (dividends, interest, or capital gains).

Security vs Bond

Aspect	Security	Bond
Definition	Broad category of tradable financial instruments (equity, debt, hybrid)	Specific type of debt security representing a loan to an issuer
Ownership	Can represent ownership (equity) or a loan (debt)	Always represents a debt obligation
Maturity	Equities have no maturity; debt securities do	Fixed maturity date when principal is repaid
Returns	Dividends, interest, or capital appreciation	Fixed or floating interest payments (coupons)

A bond is a type of security—specifically, a debt security. All bonds are securities, but not all securities are bonds. Equities and hybrid instruments are securities but not bonds. In Indian banking, when regulatory documents mention "securities," they refer to the entire universe; when they say "bonds," they mean debt instruments only.

Frequently Asked Questions

Q: Are securities the same as shares? No. Shares (equities) are one type of security. Securities also include bonds (debt), debentures, government securities, and hybrid instruments. All shares are securities, but not all securities are shares.

Q: What is the difference between a security and a bank deposit? A bank deposit is a liability for the bank and a claim on it; it is not a security. A security is a tradable instrument that can be sold to another investor. Deposits are typically illiquid before maturity; securities can be sold in secondary markets. Deposits are insured by the DICGC up to ₹5 lakh; securities carry market risk.

Q: Do I pay income tax on returns from securities? Yes. Dividends from equities, interest from bonds, and capital gains from selling securities are all taxable under the Income-tax Act. Short-term capital gains (held less than 1 year for equities, less than 3 years for debt) are taxed at ordinary rates; long-term capital gains attract preferential rates. Dividend income is taxed as per your slab rate.
