U.S. spot Bitcoin and Ethereum exchange-traded funds posted their strongest combined week of net inflows in 2026 in the week ending August 21, drawing roughly $2.6 billion as trading activity accelerated. Two days later, Term Labs confirmed that a governance exploit had affected its Term Finance vaults, with blockchain-security firms estimating losses of about $8.5 million.
Bitcoin and Ether ETFs post 2026s strongest inflow week
The Block reported that U.S. spot Bitcoin ETFs took in approximately $1.9 billion in net inflows during the week ending August 21. Spot Ethereum ETFs added $697.2 million, making it the strongest weekly inflow period of 2026 for both product categories.
The combined total was about $2.6 billion. ETF trading volume across the Bitcoin and Ethereum products reached approximately $29 billion over the same period, a sharp increase in market activity alongside the inflows.
Bitcoin briefly traded above $79,000 during the week, while Ether traded near $2,423, according to the report. Those price points provide the immediate market backdrop for the fund flows, although the reported weekly figures do not by themselves establish why investors committed capital or how long the demand will persist.
The figures also put the Bitcoin and Ether markets in focus beyond their underlying spot venues. Net inflows measure money entering ETFs after outflows are accounted for, while the volume figure captures trading in the funds themselves. Both indicators rose together in the reported week.
Term Finance governance exploit drains most vault-product TVL
On August 23, Term Labs confirmed that a governance exploit affected Term Finance vaults.
PeckShield and CertiK independently estimated the losses at roughly $8.5 million, including approximately 2,843 ETH and 1.68 million USDC, according to The Block. Those figures were not directly confirmed by Term Labs.
The affected vault-product TVL stood near $12.45 million before the attack; about 68% was reportedly drained.
A governance exploit concerns a protocols decision-making or control processes and does not necessarily mean the assets used by depositors failed. The supplied reporting leaves the precise exploit path, the status of the funds and any remediation plan unspecified.

SEC scrutiny converges on crypto vaults and on-chain lending
The exploit arrived against an already active policy discussion around crypto vaults and lending products. In a July 22 statement published by the U.S. Securities and Exchange Commission, Commissioner Hester Peirce said managers of crypto vaults and on-chain lending strategies may need to assess whether their activities fall under federal securities laws.
Peirce‘s SEC statement placed particular attention on the people or entities managing such strategies, rather than treating the technology label alone as determinative. It is a commissioner’s statement, not a finding that Term Finance or another named protocol violated securities law.
For market participants, the contrast is immediate: ETF investors recorded the years strongest weekly allocations into regulated spot Bitcoin and Ethereum vehicles as a vault-focused DeFi protocol faced a governance incident that reportedly removed more than two-thirds of its vault-product TVL. The structures and risks differ, but both developments sharpen attention on the handling, management and custody of crypto exposure.
