US Treasury Buyback Sparks 9% Zcash (ZEC) Rally to $557

Zcash (ZEC) surged about 9% on Aug. 19, climbing to a session high of $557 after the U.S. Treasury said it would double its bond buyback program to $4 billion, a macro catalyst that lifted the entire altcoin complex. Most of ZEC’s gain was compressed into roughly one hour of trading, with the token advancing from just above $503 to $557 and pushing its market capitalization to about $9.3 billion, according to market data. The Treasury announcement also helped Ether break back above $2,000 for the first time in more than two months; prior to the release, Ether had spent most of the period since Aug. 8 below $1,900, with only brief intraday breaks above that level. Ether touched an intraday high of $2,112 before consolidating below $2,090, and its market cap rose from under $230 billion to about $251 billion in a near-10% move. Bitcoin briefly approached $70,000 during the same session. The risk-on wave drove the combined market capitalization of all altcoins back above $1 trillion, a level not seen in about a month. ZEC outperformed in the privacy segment while Monero fell about 0.9%; HYPE, XRP and SOL each gained more than 6%, XLM added about 7.5%, and LEO and TRX were among the few decliners. Analyst Michaël van de Poppe, chief investment officer at MN Fund, described Ether’s breakout as “stunning” in social-media commentary and said a sustained hold above $2,000 would open a path toward $2,250, the $2,465 high and potentially $2,900. He added that a sequence of higher highs would confirm the bear market is over. For ZEC, the session was a reminder of how directly macro liquidity signals can feed into the privacy sector: nearly all of the advance came immediately after the Treasury statement, highlighting flow-driven momentum rather than a gradual build in demand.

Parallel to the price surge, institutional infrastructure for Zcash advanced on Aug. 18-19. Grayscale submitted a fourth amendment to its Zcash Trust registration statement with the U.S. Securities and Exchange Commission, outlining a conversion to a spot ETF. The filing reviewed by our desk states that the trust would list on NYSE Arca under the ticker ZCSH. It also discloses that DCG International Investments, a subsidiary of Grayscale’s parent company Digital Currency Group, is in discussions to acquire 200,000 ZEC through the trust, roughly $110 million at current market prices. Grayscale was careful to characterize the arrangement as non-binding: the filing says the actual number of tokens acquired could increase or decrease, and the purchase may not take place at all. The manager has previously launched several other altcoin products, including a staking-focused Avalanche fund and a Hyperliquid spot ETF. Trading data for the currently unlisted ZCSH show volume climbed above $23 million in November 2025 but has stayed under $5 million since June, illustrating the relatively limited secondary market the ETF conversion would aim to expand. On the mining side, Nasdaq-listed Cypherpunk Technologies said it activated its Cypherpunk Mining operation on Aug. 18, describing the facility as immediately the largest on the Zcash network. The company, which positions itself as a privacy-technology firm and treasury operator that accumulates ZEC, said the equipment spans multiple U.S. sites and represents a meaningful share of total network hash rate. It said the structure gives investors exposure to both mining economics and the value of its Zcash holdings. Together, the exchange listing plan, the potential DCG-affiliated token purchase and the new mining capacity point to a broadening institutional footprint for an asset that has historically traded mainly on retail venues.

Taken together, the two threads tell a converging story for Zcash: a privacy asset gaining momentum while institutional rails expand. The primary document is the SEC registration amendment we reviewed, which states Grayscale intends to list the trust on NYSE Arca under ZCSH and discloses that a DCG affiliate is negotiating to buy 200,000 ZEC. That commitment is non-binding, but its presence in an official filing is a concrete marker of institutional interest. The Treasury-driven rally adds a macro tailwind, and the new Cypherpunk mining capacity reinforces the supply-side buildout. Spot data shows ZEC up about 10.8% in the past 24 hours. The next catalyst is whether the SEC clears the conversion and whether the purchase becomes binding.
