[Bitcoin Options Bearish Sentiment Rises to Five-Year High, Open Interest Reaches $33 Billion] On March 20, VanEck's latest Bitcoin on-chain report revealed that bearish sentiment among Bitcoin options traders has risen to its highest level in five years. Last month's put/call ratio peaked at 0.84, with an average of 0.77, placing it in the most bearish 9% range since mid-2019. The total open interest in options has surpassed $33 billion, with premiums on put options reaching an all-time high. Institutional investors are purchasing large-scale downside protection. Analysts believe this may be related to macro factors such as escalating tensions in the Middle East, regulatory risks, and liquidity concerns.
