Premium Regimes
When futures trade above spot, upside expectation or long leverage demand may be strong. If funding is also elevated, check for overheating.
If the premium expands too quickly, arbitrage incentives increase, and the premium can compress rapidly when the market shakes.
Discount Regimes
When futures trade below spot, downside concern or short demand may be strong. A deep discount can indicate fear or poor liquidity.
If the discount narrows while price stabilizes, risk aversion may be easing.
Limits of Interpretation
Basis differs by source because spot/futures liquidity and reference prices vary by exchange.
Basis is not a directional prediction tool. It shows market price structure and should be read with CVD, OI, and funding.
