1799 reads · Last updated: November 12, 2025

Fixed income refers to investment products or strategies with fixed income as the main characteristic. Fixed income products typically include bonds, fixed deposits, wealth management products, etc., whose return rate is fixed or can be determined in advance. Compared to other investment products, fixed income investments have lower risk and stronger stability, making them suitable for investors with lower risk preference.

Core Description

Fixed income investments provide steady, predictable income streams and typically involve lower risk than equities.
These products play a crucial role in portfolio diversification and capital preservation, especially during market volatility.
Understanding their calculation, benefits, risks, and practical application is essential for building a resilient investment foundation.

Definition and Background

Fixed income refers to a class of investment instruments where returns are delivered as regular, predetermined payments—usually in the form of interest—accompanied by the eventual return of principal at maturity. Common examples include government bonds, corporate bonds, municipal bonds, and certificates of deposit. The primary feature of fixed income products is their ability to generate a reliable cash flow, often making them a preferred choice for risk-averse investors or those seeking stability amid market fluctuations.

Historically, fixed income dates back to early civilizations issuing promissory notes or simple bonds to fund public works and wars. Over centuries, innovations such as government and corporate bonds, mortgage-backed securities, and, more recently, green bonds and ETFs have evolved the landscape. The global expansion of these products has allowed individual and institutional investors to pursue a wide range of financial objectives such as capital preservation, income generation, and effective liability management.

Today, fixed income markets are integral to the global financial system, facilitating stable investment options for pension funds, insurance companies, family offices, and retail investors. Platforms like Longbridge have streamlined access, enabling diversified participation and transparency for users of all backgrounds.

Calculation Methods and Applications

Key Calculations

Precise calculation methods form the basis of sound fixed income investing. The main formulas include:

Coupon Rate:
Represents annual interest as a percentage of a bond’s face value.
Coupon Rate = (Annual Coupon Payment / Face Value) × 100%
If a bond pays USD 40 annually on a USD 1,000 face value, its coupon rate is 4%.

Yield to Maturity (YTM):
Estimates the total annual return if a bond is held until maturity, factoring in all coupon payments and the difference between purchase price and face value.
YTM = [C + (F - P) / N] / [(F + P) / 2]
Where C = annual coupon, F = face value, P = price, N = years to maturity.

Current Yield:
Shows annual return based only on coupon and current price (ignores maturity value).
Current Yield = (Annual Coupon Payment / Market Price) × 100%

Accrued Interest:
Determines interest earned but not yet paid when bonds are traded between coupon dates.
Accrued Interest = (Coupon Payment × Days Since Last Payment) / Days in Coupon Period

Duration:
Measures a bond’s sensitivity to interest rate changes. Examples include Macaulay Duration and Modified Duration.

Calculation	Formula
Coupon Rate	(Annual Coupon / Face Value) × 100%
YTM (approx.)	[C + (F – P) / N] / [(F + P) / 2]
Current Yield	(Annual Coupon / Market Price) × 100%
Accrued Interest	(Coupon × Days Since Last Payment) / Period Days

Real-World Example (Non-China Case)

A U.S. Treasury bond has a USD 1,000 face value, a 4% annual coupon, trades at USD 950, and matures in 5 years.

Coupon Rate: 40 / 1,000 = 4%
YTM (approx): [40 + (1,000 – 950) / 5] / [(1,000 + 950) / 2] ≈ 5.13%
Current Yield: 40 / 950 ≈ 4.21%

These calculations are regularly integrated into online investment tools and platforms like Longbridge, helping investors evaluate options, assess risk, and align fixed income products with their financial objectives.

Comparison, Advantages, and Common Misconceptions

Fixed Income vs. Equities

Stability vs. Growth: Fixed income offers stable, predictable returns ideal for capital preservation. Equities provide higher growth potential but with increased volatility and risk.
Risk Profile: Government bonds such as U.S. Treasuries are generally safer than most stocks, while equities can experience sharp price movements and there is a risk of losing principal.
Liquidity: Some bonds, notably government ones, are highly liquid. Others, like certain corporate bonds or structured notes, may be harder to sell quickly.

Advantages

Predictable Payments: Investors can plan future cash flows with regular coupon payments and principal returns.
Capital Preservation: Especially for high-grade government instruments, the risk of losing principal is usually minimal.
Diversification: Fixed income typically moves differently from equities, providing balance during market downturns.
Tax Efficiency: In some markets, products such as municipal bonds offer tax advantages.
Downside Protection: Government bonds often rise in value during equity market stress.

Disadvantages

Lower Returns: Fixed income generally underperforms equities in the long run, particularly during bull markets.
Interest Rate Risk: Rising rates drive bond prices lower.
Credit and Default Risk: There is a risk that bond issuers fail to honor payments.
Inflation Risk: Fixed payments lose purchasing power if inflation exceeds bond yields.

Common Misconceptions

“Bonds are risk-free.” Even government bonds face inflation and interest rate risk, while corporate and high-yield bonds can default.
“No liquidity concerns.” Some bonds lack active secondary markets, making early sale costly or difficult.
“Fixed income is immune from market shifts.” Value can fluctuate, especially with interest rate and credit changes.

Practical Guide

Identifying Goals and Risk Preferences

Assess your objectives: Are you focused on income, capital preservation, or diversification?
Determine risk tolerance: Conservative investors may prefer government bonds, while those seeking higher yield might consider corporate options with higher risk.

Building a Fixed Income Portfolio

Diversify: Allocate across various types (government, corporate, short- and long-term) and geographies to manage specific risks.
Balance maturities: Staggering bond maturities—also known as “laddering”—can reduce reinvestment and interest rate risk.

Analyzing Key Metrics

Monitor yield, credit rating, and duration for each instrument.
Compare products using online calculators or investment platforms.

Case Study: Portfolio Stability During a Downturn (Fictitious Example)

During an economic downturn similar to 2008, an investor held a balanced portfolio: 60% stocks, 40% U.S. Treasury and investment-grade bonds. While equity holdings dropped 35%, the fixed income portion held its value and even gained as investors moved to safety. Overall, the portfolio’s total decline was limited to 18%, allowing quicker recovery and reducing the likelihood of emotional selling at the market’s bottom.

Avoiding Common Mistakes

Do not chase high yields without understanding credit risks.
Watch for interest rate and reinvestment risk, especially for callable or long-dated bonds.
Regularly review and rebalance portfolio allocations to maintain desired risk/return characteristics.

Hurdle Rate

The Hurdle Rate, also known as the Minimum Acceptable Rate of Return (MARR) or Required Rate of Return (RRR), is the minimum rate of return on an investment project that a company or investor is willing to accept before proceeding with the investment. This rate is set by the company's management or investors and serves as a benchmark for evaluating the feasibility of investment projects. The hurdle rate takes into account the cost of capital, risk premium, and other factors to ensure that the investment yields sufficient returns to compensate for the risks involved. If the expected return on a project is below the hurdle rate, the project is typically rejected. The hurdle rate is crucial in capital budgeting and project evaluation, aiding companies in effective resource allocation and risk management.

Horizontal Spread

A Horizontal Spread, also known as a Time Spread or Calendar Spread, is an options trading strategy. This strategy involves simultaneously buying and selling options contracts with the same strike price but different expiration dates. Typically, a trader will buy a long-term option and sell a short-term option. The goal of a horizontal spread is to profit from the difference in time value, especially when the underlying asset's price is not expected to move significantly. By employing this strategy, traders can benefit from the different rates of time decay (the reduction in the value of an option as it approaches its expiration date). Horizontal spreads are suitable for investors who have an expectation of market volatility but are uncertain about the specific direction of the price movement.

Box Spread

A box spread, or long box, is an options arbitrage strategy that combines buying a bull call spread with a matching bear put spread. A box spread can be thought of as two vertical spreads that each has the same strike prices and expiration dates.Box spreads are used for borrowing or lending at implied rates that are more favorable than a trader going to their prime broker, clearing firm, or bank. Because the price of a box at its expiration will always be the distance between the strikes involved (e.g., a 100-pt box might utilize the 25 and 125 strikes and would be worth $100 at expiration), the price paid for today can be thought of as that of a zero-coupon bond. The lower the initial cost of the box, the higher its implied interest rate. This concept is known as a synthetic loan.

Equity Fund

An equity fund is an investment vehicle that pools money from many investors to be managed by professional fund managers, primarily investing in the stock market. The goal of an equity fund is to achieve capital appreciation by investing in various companies' stocks. Depending on the investment strategy and objectives, equity funds can be classified into actively managed equity funds and passively managed equity funds. Actively managed equity funds involve fund managers actively selecting and adjusting the stock portfolio to achieve returns that exceed the market average. Passively managed equity funds typically track a specific stock index, such as the S&P 500, aiming to replicate the performance of that index.

Stock Dividend

A stock dividend is a payment made by a corporation to its shareholders in the form of additional shares, rather than cash. When a company earns a profit, it may choose to distribute part of it to shareholders by issuing new shares. Each shareholder receives a proportionate number of additional shares based on their existing holdings. The issuance of stock dividends does not alter the total market value of the company but increases the total number of shares outstanding, thereby diluting earnings per share. Stock dividends are typically used when a company wants to retain cash for reinvestment or other purposes while still providing a return to shareholders.

Stock Split

A stock split is a corporate action in which a company increases the number of its outstanding shares by issuing more shares to current shareholders, thereby reducing the price per share. A stock split does not change the company's overall market capitalization or the total value of a shareholder's holdings; it merely reduces the price per share while increasing the number of shares held by each shareholder. For example, in a 2-for-1 stock split, each share held by a shareholder is split into two shares, and the price of each share is halved. Stock splits are typically undertaken when a company's share price has become relatively high, making the shares more affordable and attractive to investors.
