The Inverse Relationship
Bond prices and bond yields move in opposite directions. This is the fundamental principle. Here's why:
Fixed Coupon Payments: A bond pays a fixed interest rate (coupon) over its lifetime.
Changing Market Interest Rates: Interest rates in the broader economy fluctuate.
Adjusting to Market: When market interest rates rise, newly issued bonds offer higher yields. To remain competitive, existing bonds with lower coupon rates must become cheaper so their effective yield matches the market. This means their price falls. The opposite happens when market interest rates fall.
Example
Imagine a bond with a $1,000 face value and a 5% coupon rate, paying $50 annually. If market interest rates rise to 6%, new bonds will offer $60 annually for the same $1,000. To compete, the price of the 5% bond must fall so that the $50 payment represents a 6% yield on the lower price.
Bond Yields and TLT
TLT is an exchange-traded fund (ETF) that tracks the performance of long-term U.S. Treasury bonds. This means its price is heavily influenced by changes in bond yields:
Rising Yields: When yields rise (meaning bond prices fall), TLT's price generally declines.
Falling Yields: When yields fall (meaning bond prices rise), TLT's price generally increases.
Why this matters for TLT:
Interest Rate Sensitivity: TLT is considered very sensitive to interest rate changes because it focuses on long-term bonds. Long-term bonds have a greater price fluctuation in response to yield changes than short-term bonds.
Investor Sentiment: TLT is often seen as a "safe haven" asset. In times of economic uncertainty, investors may flock to TLT, pushing its price up and yields down. Conversely, when the economy is strong, investors may move away from TLT, causing its price to fall and yields to rise.

Key Takeaway
Understanding the inverse relationship between bond prices and yields is crucial for investing in bond ETFs like TLT. By tracking interest rate trends and market sentiment, investors can better anticipate how TLT's price might be affected.
