We agree about the definition of backwardation. I am disagreeing with the post's statement that backwardation implies the invasion is "already priced in" to inflation, when at the time of writing they implied a rapid recovery.
If you look at the curve since OP, you'll see it's is actually less backwardated than it's been all year (due to repeated releases from the US reserves). But long term futures are near their highest - suggesting a worse picture for impact on consumer prices over time.
"Backwardation is when the current price of an underlying asset is higher than prices trading in the futures market."
