[Analysis: The interest rate cut of the Federal Reserve and the purchase of short-term treasury bond bonds are good for the crypto market, but liquidity is still weak at the end of the year] According to options data analyst Adam@Greeks.live The just concluded Federal Reserve's interest rate meeting announced a 25 basis point cut in interest rates, and restarted the purchase of US $40 billion of short-term US treasury bond bonds, releasing a clear dove signal to supplement the liquidity of the financial system, which is good for the market. However, it is still too early to reintroduce quantitative easing (QE) and restart the bull market. The cryptocurrency market has poor liquidity and low market activity near Christmas and annual delivery, and the bull market momentum is limited. Data shows that by the end of December, the cryptocurrency options market had accumulated over 50% of its options positions, with Bitcoin's maximum pain point at the $100000 integer point and Ethereum's maximum pain point at $3200. The implied volatility (IV) of the main maturities this month is showing a downward trend, and the market's expectations for volatility this month are gradually weakening. In addition, the Skew indicator continues to be negatively biased, with Put prices significantly higher than Call prices in the same Delta, reflecting a stable market and the dominance of hedging strategies. At the same time, more traders are using put options to guard against market downturns. Overall, the cryptocurrency market is currently in a low mood with poor liquidity, and the mainstream view is that the options market generally expects a slow decline. However, we need to be alert to the possibility of market reversal caused by sudden positive news, although this possibility is low.
