TLT Covered Call: Strike Selection, Premium & Risk
How to sell covered calls on iShares 20+ Year Treasury Bond ETF — optimal strikes, expected premium, and the risks that actually matter for a large-cap etf name.
Is TLT a good covered call candidate?
TLT (iShares 20+ Year Treasury Bond ETF) is one of the most heavily traded ETFs for options strategies. Penny-wide bid/ask spreads and deep open interest on every strike make it ideal for premium sellers. Because TLT is a basket rather than a single name, single-stock earnings risk is diffused, which is a meaningful edge for consistent income.
Strike selection for a TLT covered call
For TLT covered calls, target strikes 5-8% out of the money at deltas around 0.20-0.30. Use 30-45 DTE — the sweet spot for theta-to-gamma balance. On a moderate-volatility name like TLT, going closer to the money chases premium at the cost of a much higher assignment probability — the risk of being called away becomes meaningful below 5-8% OTM.
Expected premium and income on TLT
Typical monthly premium collected on TLT runs around 1.0-2.0% of capital, which annualizes to roughly 12-24% if you sell new contracts every cycle. Capital required to run a single contract wheel on TLT is under $5,000 — the share price and the 100-share lot size set the minimum, not the strategy.

Risk management for TLT covered call trades
The core risk on a covered call is opportunity cost: if the stock rips through your strike, your upside is capped. You still profit, just less than someone who held the shares outright. TLT moves in a moderate-volatility range most of the time, but earnings week and sector rotations can still produce 5%+ single-day prints. ETFs diffuse single-stock risk but still carry basket-level exposure — a sector ETF will move on macro shocks even if individual holdings are fine.
