Bitcoin futures basis spreads, the difference between the futures price and the spot price, have grown to their highest level since the digital asset's previous history at the end of 2021, according to The Block. Luuk Strijers, Deribit's chief commercial officer, said that the current basis spreads, which are annualized at 18 to 25 percent, reflect growing market momentum since the ETF's approval in January as well as anticipation of the impact of Bitcoin's halving. He said, "This yield is so incredibly high, it's a very bullish indicator and is being driven by new daily inflows into the system as a result of the approval of the Spot Bitcoin ETF as well as the expected impact of the Bitcoin halving."
