Accrued Interest: What Traders Need to Know

Accrued interest is a fundamental concept in trading, especially when dealing with fixed-income securities like bonds, but it also appears in other asset classes such as CFDs and forex. Simply put, accrued interest refers to the amount of interest that has accumulated on a financial instrument since the last interest payment date, but which has not yet been paid out to the holder. Understanding accrued interest is important for traders because it affects the pricing and valuation of securities, as well as the calculation of returns.

How Accrued Interest Works

When you invest in a bond or similar fixed-income product, the issuer pays interest at regular intervals—usually semi-annually or annually. However, the bond accrues interest every day, meaning the interest is effectively earned each day even though the payment happens less frequently. If you buy or sell the bond in between interest payments, the price you pay or receive will include accrued interest to compensate the seller for the interest they earned before the sale.

The basic formula for calculating accrued interest is:

Formula: Accrued Interest = (Face Value) × (Coupon Rate) × (Number of Days Since Last Payment / Number of Days in Coupon Period)

For example, consider a bond with a face value of $1,000 and a coupon rate of 6% paid annually. If you buy the bond 90 days after the last coupon payment, and the coupon period is 365 days, the accrued interest would be:

Accrued Interest = $1,000 × 6% × (90/365) = $14.79

This $14.79 is added to the bond’s clean price (the price without accrued interest) to give the dirty price (the price including accrued interest) that the buyer actually pays.

Real-Life Trading Example

In the stock market, accrued interest is less directly relevant because stocks do not pay interest. However, in trading CFDs on bonds or indices, accrued interest can impact pricing. For instance, if you are trading a CFD based on a bond index, the price of the CFD will factor in the accrued interest of the underlying bonds. Similarly, in forex trading, accrued interest is reflected through rollover rates or swap points, representing the interest differential between currencies held overnight.

Suppose a trader holds a CFD on a government bond that pays interest semi-annually. If the trader closes the position just before the interest payment date, the accrued interest earned by the trader will be factored into the final settlement price, ensuring they receive the interest earned up to that point.

Common Mistakes and Misconceptions

One common misconception is confusing accrued interest with dividends or coupon payments themselves. Accrued interest is not a payment but rather interest that has accumulated over time and is reflected in the price of the security. Another frequent mistake is ignoring accrued interest when buying or selling bonds, which can lead to mispricing or unexpected gains or losses.

In CFD and forex trading, traders sometimes overlook how rollover interest (which is effectively accrued interest on currency pairs) can affect profitability. For example, holding a currency pair with a negative interest rate differential overnight may result in paying rollover fees, impacting the overall return.
