BTC and ETH spot ETFs went their separate ways yesterday.
On October 15, U.S. Eastern Time, the U.S. spot $BTC ETF saw $5.06 million in net inflows—after $261 million flowed out the previous day, it was back in the green the very next day. On the same day, the spot $ETH ETF saw $60.22 million in net outflows. Combined, the two saw net outflows of $55.16 million, while all 15 crypto ETFs saw total net outflows of $89.4 million.
The details tell an even clearer story: of the 12 BTC products, only BlackRock's IBIT saw buying, with net inflows of $16.79 million. Grayscale's Mini BTC and Invesco's BTCO both saw outflows, while the other products had no net flows. On the ETH side, BlackRock's ETHA alone saw $44.39 million in net outflows, accounting for more than 70% of the day's total ETH outflows. Altcoin ETFs were also entirely in the red: SOL, HYPE, and Zcash all saw net outflows, while only NEAR recorded a modest $1.13 million in net inflows.
Looking at a longer timeframe, spot BTC ETFs have recorded cumulative net inflows of $2.1 billion over the past 30 days, while spot ETH ETFs have seen cumulative net outflows of $360 million. Institutions have been consistent in their stance: BTC is a safe-haven holding, while ETH is still waiting for a story compelling enough to bring money back.
My take: This divergence is worth watching in the short term. Right now, relative strength is being driven by a "flight-to-safety bias." If the FOMC signals a dovish stance at the end of October, ETH could have the greatest rebound potential, having been hit hardest by outflows. If the Fed remains hawkish, funds will continue to take shelter in BTC. In either scenario, watching whether ETF outflows narrow is more useful than trying to guess price levels.
