BIL Iron Condor Strategy
BIL (State Street SPDR Bloomberg 1-3 Month T-Bill ETF), in the Financial Services sector, (Asset Management - Bonds industry), listed on AMEX.
The State Street SPDR Bloomberg 1-3 Month T-Bill ETF (BIL) is designed to closely mirror the price appreciation and income generation of the Bloomberg 1-3 Month U.S. Treasury Bill Index, prior to accounting for its operational costs. This fund primarily invests in government-issued U.S. Treasury Bills that have a remaining term of just one to three months. Due to this ultra-short maturity profile, the ETF exhibits lower sensitivity to shifts in interest rates compared to debt instruments with longer durations. Its holdings are adjusted and rebalanced on the last trading day of each month.
BIL (State Street SPDR Bloomberg 1-3 Month T-Bill ETF) trades in the Financial Services sector, specifically Asset Management - Bonds, with a market capitalization of approximately $46.14B, a beta of 0.00 versus the broader market, a 52-week range of 91.26-91.78, average daily share volume of 11.0M, a public-listing history dating back to 2007. These structural characteristics shape how BIL etf options price implied volatility around earnings windows, capital events, and macro-driven sector rotations.
A beta of 0.00 indicates BIL has historically moved less than the broader market, dampening realized volatility and producing tighter expected-move bands per unit of dollar exposure. BIL pays a dividend, which adjusts put-call parity and shifts the ex-dividend pricing across the listed chain.

Current BIL snapshot
As of June 30, 2026, spot at $91.65, ATM IV 375.70%, IV rank 78.59%, expected move 107.71%. The iron condor on BIL below is built from the same end-of-day chain, with strikes snapped to listed contracts and premiums pulled from the bid/ask midpoint at a 17-day expiry.
Why this iron condor structure on BIL specifically: BIL IV at 375.70% is rich versus its 1-year range, which favors premium-selling structures like a BIL iron condor, with a market-implied 1-standard-deviation move of approximately 107.71% (roughly $98.72 on the underlying). The 17-day window matched to the front-month expiry keeps theta exposure bounded while still capturing the post-snapshot move; longer-dated BIL expiries trade a higher absolute premium for lower per-day decay. Position sizing on BIL should anchor to the underlying notional of $91.65 per share and to the trader's directional view on BIL etf.
BIL iron condor setup
The BIL iron condor below is built from the end-of-day chain, with each option leg priced at the bid/ask midpoint of its listed strike. With BIL near $91.65, the first option leg uses a $96.23 strike; additional legs (when the strategy has them) anchor to spot-relative offsets. Premiums come from the bid/ask midpoint on the listed BIL chain at a 17-day expiry; the cross-strike IV skew is reflected directly in the per-leg values rather than approximated. Quantity sizing assumes one contract per option leg (or 100 BIL shares for the stock leg in covered calls and collars).

| Buy 1 | Call | $100.82 | N/A |

BIL thesis for this iron condor
The market-implied 1-standard-deviation range for BIL extends from approximately $-7.07 on the downside to $190.37 on the upside. A BIL iron condor is a delta-neutral premium-collection structure that pays off when BIL stays inside the inner short strikes through expiration; the wing width should reflect the trader's tolerance for the maximum loss scenario where the underlying breaches an outer strike. Current BIL IV rank near 78.59% sits in the upper third of its 1-year distribution, which historically reverts; this raises the bar for premium-buying structures and lowers it for premium-selling structures on BIL at 375.70%. As a Financial Services name, BIL options can move on sector-level news flow (peer earnings, regulatory updates, industry-specific macro data) in addition to BIL-specific events.
BIL iron condor positions are structurally neutral / range-bound; the modeled P&L assumes European-style exercise at expiration and ignores early assignment, transaction costs, dividends paid before expiry on the stock leg (when present), and the bid-ask spread on the listed chain. BIL positions also carry Financial Services sector concentration risk; news flow inside the sector (peer earnings, regulatory shifts, supply-chain headlines) can move BIL alongside the broader basket even when BIL-specific fundamentals are unchanged. Short-premium structures like a iron condor on BIL carry tail risk when realized volatility exceeds the implied move; review historical BIL earnings reactions and macro stress periods before sizing. Always rebuild the position from current BIL chain quotes before placing a trade.
