Summary

  • This month’s spotlight is on seasonality in crypto markets - the report takes a deeper dive into dissecting seasonality patterns in crypto, looking beyond simple returns. 

  • ETH continued its underperformance last month with the worst return amongst the top 10 market cap coins, while TON led the pack (Figure 1.1).

  • This was the first March since 2020 that BTC was down (Figure 1.3)

  • BTC dominance continued to climb, surpassing the February high of 62% (Figure 1.6)

  • With BTC’s slight retreat in mindshare since the start of the year, the monthly ETF flow was not interesting (Figure 2.1). There was a single 400+ BTC outflow day at the start of March, followed by two consecutive 350+ BTC outflow days, but this was slightly offset by 10 consecutive inflow days, albeit at smaller sizes (Figure 2.2)

  • There was a general decline in global derivatives trading volumes across last month (Figure 4.3) as well as smaller magnitudes of liquidations, perhaps due to whipsawing markets and a malaise across traders that is suppressing risk appetite.

  • There was a sudden pop in both BTC and ETH’s put/call ratio at the end of the month, with the latter going up from 0.5 to 0.7, suggesting increasingly defensive positioning (Figure 5.1). This came with a notable dip in short-term risk reversals (Figure 5.3) and also an increase in butterflies (Figure 5.4).  Implied Volatility was consistently higher than realised volatility for both assets (Figure 5.7).
