How to Calculate GILT Yields: Complete Guide

UK Government bonds, known as GILTs, are a cornerstone of many investment portfolios. Understanding how to calculate GILT yields is essential for making informed investment decisions. This comprehensive guide will walk you through everything you need to know.

What are GILTs?

GILTs (Gilt-edged securities) are bonds issued by the UK government to finance public spending. They are considered one of the safest investments available, backed by the full faith and credit of the UK government.

Key Yield Metrics

Yield to Maturity (YTM)

Yield to Maturity is the total return you can expect if you hold a GILT until it matures. It accounts for:

• The coupon payments you'll receive
• The difference between the purchase price and face value
• The time remaining until maturity

Formula: YTM considers the present value of all future cash flows (coupons and principal) and equates them to the current market price.

Running Yield

Running Yield (also called Current Yield) is simpler to calculate. It's the annual coupon payment divided by the current market price.

Formula: Running Yield = (Annual Coupon / Current Price) × 100

Total Return

Total return includes:

• All coupon payments received
• Capital gain or loss from price changes
• Reinvestment of coupon payments

Factors Affecting GILT Yields

Several factors influence GILT yields:

1. Interest Rates: When Bank of England rates rise, GILT prices typically fall, increasing yields

2. Inflation Expectations: Higher inflation expectations lead to higher yields

3. Time to Maturity: Longer-dated GILTs generally offer higher yields

4. Credit Risk: UK government bonds have minimal credit risk, but economic conditions matter

5. Supply and Demand: Market dynamics affect pricing
