Contango and backwardation are the two possible shapes of a commodity futures term structure — the relationship between futures prices at different expiration dates. In contango, futures prices are higher than the current spot price, with the forward curve sloping upward over time. This is the normal state for most storable commodities because futures prices must compensate for the cost of carry: the interest rate expense of financing inventory plus storage and insurance costs. Gold, silver, and most financial assets are almost always in contango because storage costs are manageable and there is no consumption urgency. In backwardation, futures prices are lower than the spot price, with the forward curve sloping downward. Backwardation occurs when the market is pricing in near-term scarcity or when the convenience yield — the benefit of holding physical inventory — is very high. When oil refiners need crude immediately to maintain operations, they bid up the spot price above the futures price, creating backwardation. Energy commodities, particularly oil and natural gas, frequently oscillate between contango and backwardation depending on inventory levels and seasonal demand. The shape of the futures curve has profound implications for investors: long commodity positions in contango markets incur negative roll yield (selling expiring near-month contracts at low prices and buying more expensive far-month contracts), while backwardation markets generate positive roll yield. The Keynes-Hicks theory of normal backwardation argues that futures prices are set below expected future spot prices to compensate speculative buyers for bearing the risk that producers hedge away — implying commodity futures should always offer a positive risk premium. However, empirical evidence is mixed, and the term structure shape remains the dominant practical consideration for commodity investors.
See calculator interface for applicable formulas and inputs. This formula calculates contango backwardation by relating the input variables through their mathematical relationship. Each component represents a measurable quantity that can be independently verified.
- 1Collect the futures prices for multiple consecutive expiration months (e.g., Jan, Feb, Mar, Apr) and the current spot price.
- 2Plot or tabulate the prices against time to expiration to visualize the term structure shape.
- 3Calculate the spread between consecutive months: TS_Slope = (F2 − F1) / F1 / months × 12 × 100 (annualized %/yr).
- 4Determine the market state: positive TS_Slope = contango; negative TS_Slope = backwardation.
- 5Calculate the roll yield for a long position rolling from F1 to F2: Roll_Yield% = (F1 − F2) / F2 × 100.
- 6Estimate the implied convenience yield from the term structure using the cost-of-carry equation: CY = r + u − (ln(F/S)/T).
- 7Use the term structure shape to assess investment cost and optimal positioning strategy.
Extreme storage constraint caused steepest contango in WTI history
During April 2020 COVID demand collapse, crude oil storage at Cushing approached capacity. Spot and near-month prices collapsed as physical holders tried to avoid taking delivery, while deferred months priced in expected recovery. The May-June spread of $7 per barrel is an annualized contango of over 39% — a massive headwind for ETFs and funds holding long WTI futures. The United States Oil Fund (USO) lost approximately 75% of its value in weeks partly due to this roll cost.
Spot backwardation vs. near-term dip is complex seasonal pattern
Natural gas markets exhibit complex seasonal term structures. The spot price of $3.30 exceeds the November futures at $3.20, creating backwardation at the front. However, the December price at $3.05 dips (seasonal lull after November heating demand peak) before recovering in January for deep winter. A long position rolling from November to December captures a positive roll yield of 4.7% but must navigate the seasonal demand pattern carefully to maintain profitable positioning.
Gold is textbook contango — always upward sloping reflecting pure financing cost
Gold's term structure is almost always in contango, with the slope directly reflecting the prevailing interest rate. At 5.3% annual rate plus 0.25% storage, the net carry is 5.55% per year or about 0.46% per month. The actual market prices (0.41%/month) are consistent with this cost structure. For investors holding gold via futures ETFs, this creates a persistent annual roll cost of roughly 5-6% at current rates, which is why many investors prefer physical gold ETFs that avoid roll costs.
Low LME warehouse stocks driving strong backwardation and backwardation premium
Copper backwardation occurs when LME warehouse stocks decline to low levels and the market prices immediate delivery at a premium to future delivery. The $150 backwardation in the cash-3M spread reflects strong near-term demand (perhaps from smelter offtake or short-covering) combined with tight warehouse stock. Long position holders rolling from cash to 3-month earn the $150 backwardation premium as roll yield — a positive return component on top of any spot price appreciation.

In practice, this edge case requires careful consideration because standard assumptions may not hold. When encountering this scenario in contango vs backwardation calculator calculations, practitioners should verify boundary conditions, check for division-by-zero risks, and consider whether the model's assumptions remain valid under these extreme conditions.

Is contango or backwardation better for long commodity investors?
Backwardation is generally better for long commodity futures investors because it generates a positive roll yield — selling expensive near-month contracts and buying cheaper deferred contracts. Contango creates a headwind: rolling means selling cheap near contracts and buying expensive far contracts. Empirical studies show that roughly two-thirds of long-run commodity futures returns in contango markets come from negative roll yield drag, while backwardated markets can generate 5-10% annual roll returns even with flat spot prices. For this reason, commodity ETF investors should closely monitor the term structure shape.
What drives a market into backwardation?
Backwardation occurs when near-term physical supply is tight relative to demand, making immediate delivery more valuable than future delivery. Key drivers include: inventory drawdowns to multi-year lows; supply disruptions (geopolitical events, extreme weather, infrastructure failures); seasonal demand peaks (natural gas in winter, gasoline in summer); and short-covering pressure as speculative shorts buy back near-month contracts. Backwardation is a signal from the market that physical supply is stressed right now, even if the market expects normalization later.
How do index funds affect the term structure?
Commodity index funds (GSCI, Bloomberg Commodity Index) maintain long exposure by mechanically rolling futures from near-month to the next month at fixed times. This predictable buying of deferred contracts and selling of near contracts tends to steepen contango curves near roll dates as index funds push up prices in the deferred months. Academic research has documented this 'index roll effect,' particularly in oil, suggesting that index fund mechanical rolling has made contango steeper and roll costs higher than they would otherwise be.
What is the theory of normal backwardation?
The theory of normal backwardation, developed by Keynes and Hicks, argues that commodity producers who hedge their future production by selling futures must offer futures buyers a discount below the expected future spot price to entice speculators to take the long side of the trade. This means futures should be priced in backwardation (below expected future spot) as compensation to speculative longs for bearing the producers' price risk. Empirically, the evidence is mixed: some commodity markets show the predicted positive risk premium, while others (particularly in contango) do not.
How should commodity ETF investors respond to contango?
Investors aware of contango drag have several strategies: (1) use physically-backed ETFs (available for gold, silver, oil to a limited extent) that avoid roll costs; (2) invest in commodity producer stocks that have built-in commodity exposure without roll costs; (3) use 'enhanced roll' strategies that roll into the cheapest available deferred month rather than mechanically rolling to the nearest month; (4) tilt toward commodities with naturally backwardated term structures; or (5) directly invest in the spot market for storable commodities with accessible storage infrastructure (e.g., gold vaulting).
What is the WTI-Brent term structure divergence?
WTI crude oil and Brent crude oil frequently have different term structure shapes due to different supply-demand dynamics. WTI's term structure is heavily influenced by US domestic storage at Cushing, Oklahoma, and US shale production levels, while Brent reflects North Sea production and international supply-demand balances. During 2020, WTI entered extreme contango while Brent remained more moderate — WTI's Cushing-specific storage constraint made its physical basis diverge sharply. Understanding these structural differences is critical for energy traders positioning across the two benchmarks.
How does the EIA inventory data affect the term structure?
The US Energy Information Administration (EIA) publishes weekly petroleum inventory reports every Wednesday, covering crude oil, gasoline, and distillate stocks. These reports are the most market-moving scheduled data releases for oil and natural gas prices. A larger-than-expected inventory build weakens spot prices and flattens or steepens the contango, while a larger draw strengthens spot prices and narrows the contango or pushes the market toward backwardation. Professional energy traders closely track inventory levels relative to seasonal norms as the primary driver of near-term term structure positioning.
Profi-Tipp
Track the 1-12 month futures spread as a percentage of spot price to get a normalized measure of term structure steepness. A WTI spread of -10% (backwardation) is historically a strong positive signal for the next-12-month return on a rolled long position; spreads of +10% (steep contango) have historically been negative for long investors.
Wussten Sie?
The term 'contango' is believed to originate from 19th century British stock exchange terminology for the premium paid to delay settlement. The opposite term 'backwardation' (from backward, opposite direction) was used to describe premiums paid for early delivery. Both terms migrated from equity settlement to commodity futures markets and are now standard industry vocabulary worldwide.
