GLD 30d IV is 24.3% vs 90d IV 23.8% — front-vs-back-month curve shape.
SPDR Gold Shares — 30d vs 90d slope, IV curve, and earnings-driven backwardation
SPDR Gold Shares (GLD) operates in the ETF - Commodity sector and has actively traded listed options. The 30-day IV reads 24.3% versus 90-day IV at 23.8%, a 30D-vs-90D slope of +0.5pp. The curve is currently flat across the front-vs-back tenors, which describes how implied volatility distributes across expirations rather than the absolute level on any single tenor. GLD expected move.
GLD term structure is flat — 30d IV (24.3%) and 90d IV (23.8%) are closely matched; the model reads the curve as neutral.
The IV term structure shows how option pricing varies across maturities. When the front month is priced richer than 90D IV (backwardation), short-dated options carry richer IV inputs than longer-dated options — useful for comparing expiration pricing, provided the inflation isn't tied to a known catalyst that compresses sharply.
The curve is not a direction predictor. It tells you whether the front month is rich, calm, or flat — interpreting that reading still requires VRP, IV Rank, and the event calendar.

One question the curve answers: is the front month richer than the back, or is it pricing a known event? The curve shape changes how IV is distributed across expirations.
Term structure is one input, not a complete signal. Interpret it alongside other volatility, liquidity, and event-risk data. Not investment advice.
Term structure shows whether short-dated IV is elevated relative to longer-dated. Backwardation (front higher than back) often signals event/earnings risk. Contango (front lower than back) signals normal calm markets.
Backwardation marks the front-month as event-sensitive in the model; contango is a stable-regime context. Earnings proximity is a separate input.

Term structure measures the SHAPE of the IV curve, not direction. Earnings within 14 days inflate front-month IV without changing the underlying volatility regime — VolRadar surfaces an earnings-driven warning to prevent treating that elevated short-dated premium as stable seller edge. Wave 1 uses static thresholds; Wave 2 will calibrate per-ticker.
SPDR Gold Shares's 30-day IV is 24.3% versus 90-day IV at 23.8%, a 30D-vs-90D slope of +0.5pp. The curve is currently pricing similar IV across the front and back of the curve, which describes how implied volatility distributes across expirations rather than the absolute level on any single tenor.
SPDR Gold Shares's 30-day and 90-day IV readings are close together — 30D at 24.3% versus 90D at 23.8%. The curve is not strongly favoring one tenor: front-month and back-month options carry comparable implied volatility. This shape sits between the typical contango and the inverted regimes that often emerge around concentrated events.
Calendar and diagonal structures derive their pricing from the IV difference between two expirations. With SPDR Gold Shares's current curve, front and back tenors carry similar IV, so calendar credits reflect time-decay differentials more than IV differentials. See the strategy comparison view for how calendars and diagonals are priced under this curve.
SPDR Gold Shares's curve is currently a flat curve — front and back tenors carrying similar IV. The 30-day IV is 24.3% versus the 90-day IV at 23.8%, a 30D-vs-90D slope of +0.5pp.
Neither clearly — SPDR Gold Shares's 30-day IV at 24.3% and 90-day IV at 23.8% are close together, so the curve is flat between the standard front-month and back-month reference tenors.
No clear premium — SPDR Gold Shares's 30-day IV at 24.3% is close to the 90-day IV at 23.8%, so short-dated and longer-dated options carry comparable implied volatility today.
Calendar and diagonal pricing comes from the IV difference between two expirations. SPDR Gold Shares's current curve reduces the IV differential that calendars usually rely on, leaving time-decay differentials as the main driver. The per-tenor IV table on this page shows the full distribution that drives this comparison.
Equity options usually carry mild contango — back-month IV slightly above front-month IV — outside of concentrated event windows. There is no single "correct" slope for SPDR Gold Shares: a normal range is more reliably read from the per-tenor table on this page than from a fixed threshold. The curve view shows the recent envelope around which the current reading sits.
