ChainCatcher reported, citing CoinDesk, that Bitcoin’s Sharpe ratio has fallen to -20. The same level appeared around the bottom areas of the 2015, 2018-19 and 2022-23 cycles. The reading places Bitcoin’s risk-adjusted return metric at an extreme level that has been associated with previous cycle lows.
Historical signals involved months of bottoming
The report noted that this signal has not historically led to an immediate rebound. Instead, similar readings were followed by several months of bottom formation. In 2015, the metric stayed in the bottom area for about five months. In the 2018-19 and 2022-23 cycles, it remained in similar bottom zones for about three months in each case.
On-chain flows also showed continued absorption by longer-term holders. Accumulation wallets took in about 125,000 BTC during the first half of June. At the same time, exchange reserves have declined by about 80,000 BTC since February, falling to around 2.71 million BTC. Whale addresses withdrew more than 11,000 BTC from exchanges over the past day.
Rebound linked to the U.S.-Iran agreement
Bitcoin rebounded from a low of $59,130 to around $65,800. According to the report, that move was driven mainly by the U.S.-Iran agreement rather than by on-chain indicators. The on-chain data showed accumulation, lower exchange reserves and whale withdrawals, but the immediate driver cited for the price rebound was the macro and geopolitical event.
The next test for Bitcoin is the Federal Reserve’s interest rate decision. The dot plot and Fed Chair Warsh’s remarks on inflation will determine whether the rebound can continue. The focus therefore shifts from the extreme Sharpe ratio reading and exchange flows to the Fed’s rate path and inflation commentary.
