Why trade options on BIL?

BIL (SPDR Bloomberg 1-3 Month T-Bill ETF) is one of the most heavily traded ETFs for options strategies. Tight spreads and good open interest across strikes make it ideal for premium sellers. Because BIL is a basket rather than a single name, single-stock earnings risk is diffused, which is a meaningful edge for consistent income.

Typical monthly premium collected on BIL runs around 0.5-1.0% of capital, which annualizes to roughly 6-12% if you sell new contracts every cycle. Capital required to run a single contract wheel on BIL is under $5,000 — the share price and the 100-share lot size set the minimum, not the strategy.

Four strategies that work on BIL

BIL options FAQ

What is the best strike price for a BIL covered call?

On BIL, target 3-5% out of the money at 0.25-0.35 delta. On a low-volatility stock like this, closer-to-the-money strikes chase premium but spike assignment probability to uncomfortable levels.

How much premium can I collect selling calls on BIL?

Typical monthly premium on BIL is 0.5-1.0% of position value, annualizing to 6-12% when you roll every cycle. Earnings months can pay 2-3x the normal rate because of elevated IV.

What is the best delta for a BIL cash-secured put?

A delta of 0.25-0.35 on BIL balances premium income with assignment probability. Many traders anchor to 0.20 delta as a starting point and adjust based on their willingness to own shares.

How much cash do I need to sell a put on BIL?

Cash required is 100 × strike price. For BIL, that's roughly under $5,000 per contract at a typical strike. Most brokers let you use margin, but for a true cash-secured put you set aside the full amount.

Is BIL a good stock for the wheel strategy?

BIL is solid for the wheel because of its reasonable spreads and low IV (modest premium, low assignment risk). It also pays a dividend, which you continue collecting while holding the shares between wheel legs.

Can you run a poor man's covered call on BIL?

Yes. Buy a 0.80+ delta LEAPS on BIL dated 12-18 months out as your synthetic long, then sell short-dated calls 3-5% above the stock at 0.25-0.35 delta. Capital tied up drops from under $5,000 to roughly 30-50% of that — a meaningful improvement when the share price is a low share price.

What expiration should I use for BIL options strategy trades?

Use 30-45 DTE as a default for BIL. This is the classic theta sweet spot and works well on a stable ticker like this.

Is BIL suitable for beginners selling options?

Yes — it's a well-known, liquid name with established options markets, which is what beginners need. Always check the bid/ask spread before entering — anything wider than 5% of the mid price is a warning sign.
