Hong Kong’s Bitcoin (BTC) and Ether (ETH) exchange-traded funds (ETFs) posted the largest-ever net outflow on Monday, May 13 — wiping all gains they’ve made since launching under two weeks ago.

Bosera, ChinaAMC and Harvest Global’s spot Bitcoin ETF funds posted net outflows of $32.7 million, with ChinaAMC’s Bitcoin fund coming in as the biggest loser on the day with $15.5 million in outflows, according to Farside Investors data.

Meanwhile, spot Ether ETFs from the same issuers saw total joint net outflows of $6.6 million. Harvest Global and ChinaAMC tied for most outflows with $3 million each.

As of Monday, all funds since their April 30 trading launch have together seen $20.9 million in total outflows, outpacing the $18.4 million in total inflows accrued as of Friday, May 10.

Monday’s outflows also mark the third trading day in a row where Hong Kong’s crypto ETFs posted net outflows, with $52.5 million in total being pulled from the funds since May 9.

It’s also the first time Harvest Global’s Bitcoin ETF saw outflows, which totaled $9.8 million.
