As of May 15, 2026, PIMCO 25+ Year Zero Coupon U.S. Treasury Index Exchange-Traded Fund (ZROZ) max pain sits at $61.00, which is above the current spot price of $60.23 (1.3% away). Spot sits within 2% of the max-pain level for PIMCO 25+ Year Zero Coupon U.S. Treasury Index Exchange-Traded Fund, the band where dealer hedging activity around the high-OI strikes can meaningfully reinforce a closing-week pin. ZROZ sits in the lower-price band (spot $60.23), where $0.50-$2.50 strike spacing makes pin-to-strike effects easy to spot but per-contract dollar gamma is smaller. Total open interest across the listed chain is comparatively thin (11.7K contracts), so single-strike pinning is less reliable than it is for high-OI names. ZROZ is currently in negative dealer gamma (-$933.4K), a regime that amplifies directional moves rather than damping them, weakening the pin-toward-max-pain bias. Max pain identifies the strike at which the aggregate dollar value of all outstanding options contracts would expire with the least total intrinsic value, a gravitational reference rather than a price target.
ZROZ Strategy Implications at the Current Max Pain Level
With spot 1.3% from the $61.00 max-pain level and PIMCO 25+ Year Zero Coupon U.S. Treasury Index Exchange-Traded Fund in a negative-gamma regime, where dealer hedging amplifies directional moves and weakens any pin, strategy selection turns on cycle position and dealer positioning. Iron condors and credit spreads centered near the max-pain strike capture the typical end-of-cycle convergence when the regime supports pinning; ratio backspreads or directional debit structures fit names where catalyst flow is likely to overwhelm the hedging-driven pull. The gamma-exposure page shows the per-strike dealer book that determines whether hedging will reinforce or fight the pin.

Frequently asked ZROZ max pain analysis questions
- What is the current ZROZ max pain strike?
- As of May 15, 2026, PIMCO 25+ Year Zero Coupon U.S. Treasury Index Exchange-Traded Fund (ZROZ) max pain sits at $61.00, which is 1.3% above the current spot price of $60.23. Max pain identifies the strike at which aggregate option-buyer payouts at expiration are minimized; it is a gravitational reference, not a price target. At a 1.3% distance, ZROZ sits inside the band where dealer hedging can mechanically pull spot toward max pain during the closing week of the expiration cycle.
- Does ZROZ pin to its max pain strike at expiration?
- ZROZ is currently in negative dealer gamma, a regime that amplifies directional moves rather than damping them. The pin-toward-max-pain bias weakens here because dealer hedging adds momentum rather than mean reversion. Total open interest across ZROZ (11.7K contracts) is one input to how plausible a clean pin is - heavier total OI concentrated at fewer strikes raises the probability; thin OI spread across many strikes lowers it. Pinning is strongest in heavily-traded names with large open-interest concentrations at high-OI strikes during the final week of an OPEX cycle. Whether ZROZ actually pins on a given expiration depends on the OI distribution, the dealer-gamma sign, and the absence of catalyst-driven moves that overwhelm hedging-driven flow.
- How is ZROZ max pain calculated?
- Max pain is computed by summing the dollar value of all in-the-money options at each candidate settlement strike across listed expirations, then selecting the strike that minimizes total intrinsic-value payout to option buyers. The calculation uses the full open-interest distribution and weighs both calls and puts. ZROZ put/call OI ratio is 0.75 - balanced, so the max-pain calculation reflects the strike where the call and put OI distributions cross rather than a single dominant side.
