Crypto Carry
分析了加密货币市场中期货与现货价差（套利收益）的动态，发现其年化收益率有时超过40%，且波动剧烈，这源于小型趋势追逐者的杠杆需求和监管保证金摩擦限制了套利资本，揭示了结构性套利限制如何放大价格低效。
We analyze the dynamics of carry in crypto markets—the difference between futures and spot prices—and document that it can reach exceptionally high levels, sometimes exceeding 40% per annum, with significant variation over time. This phenomenon reflects a substantial and volatile inconvenience yield associated with holding spot cryptocurrencies relative to futures. We trace the large and volatile crypto carry to the interplay of two main forces: (i) demand from smaller, trend-chasing investors seeking leveraged exposure and (ii) the limited deployment of arbitrage capital because of regulatory and margin frictions. Our findings highlight how structural limits to arbitrage—especially severe in the case of crypto—can amplify price inefficiencies across financial markets, offering lessons for understanding asset pricing and market behavior more generally.
