Bitcoin slipped to $61,800 on June 5, 2026, as blowout United States employment data and the disclosure of a critical Zcash vulnerability combined to dampen investor sentiment. The U.S. economy added 172,000 jobs in May, far exceeding the 85,000 positions forecast by economists.
This surprise strength in the labor market ignited concerns that the Federal Reserve may pivot back toward interest rate hikes, with market odds for such a move rising to approximately 80% by year-end.
The macroeconomic pressure was immediately visible in the bond markets. The 10-year Treasury yield jumped 6 basis points to 4.54% following the jobs report, while the two-year yield, which is more sensitive to monetary policy, rose 7 basis points to 4.12%.
As yields climbed, Bitcoin gave up its modest gains from the previous day, returning to $61,900 during U.S. morning hours before dipping to $61,800. The broader market remains on edge, as Bitcoin faces sharp correction risk if the “higher for longer” rates narrative persists.
Compounding the pressure was a crisis within the privacy-focused token Zcash (ZEC). Shielded Labs disclosed that security researcher Taylor Hornby discovered a critical “soundness bug” in the protocol’s Orchard shielded pool on May 29, 2026.
Hornby identified the flaw, which had existed undetected for four years since May 2022, using a custom auditing agent framework paired with the Anthropic Opus 4.8 AI model. The bug could have theoretically allowed an attacker to create an unlimited amount of counterfeit ZEC tokens without detection.
Market reacts as Zcash plunges on vulnerability news
The disclosure triggered a massive sell-off for Zcash, which plummeted over 30% in a 24-hour window, with some sources reporting a crash as deep as 45%. The token’s price fell to around $298 following the news.
Omkar Godbole described the severity of the flaw, noting that even the “Fed wouldn’t be able to tell” if extra dollars were printed in a similar real-world breach. This uncertainty prompted high-profile moves, such as reports that Arthur Hayes dumped his Zcash holdings once the vulnerability became public.
Analysis of the market structure reveals the crash was largely driven by spot selling rather than a cascade of leverage. ZEC experienced approximately $118 million in forced liquidations, a figure analysts consider small given that the token lost nearly half its value.
However, the derivatives market saw a surge in activity; traders opened new positions at the fastest pace on record, pushing open interest in ZEC terms to a new record high. This suggests a heavy influx of new short interest as the market processed the technical risks.
Timeline of the Zcash Orchard pool patch
Developers moved quickly to secure the network through a coordinated private effort that began on May 31, 2026. The technical fix was implemented in stages to prevent exploitation before the bug was formally announced to the public.
- May 29, 2026: Taylor Hornby discovers the Orchard circuit bug during a protocol audit for Shielded Labs.
- May 31, 2026: Developers, miners, and exchanges begin private coordination to mitigate risk.
- June 1, 2026: The technical patch for the bug is completed.
- June 2, 2026: An emergency soft fork at 02:00 UTC temporarily disables Orchard actions; the NU6.2 upgrade later restores the corrected circuit.
- June 5, 2026: Zcash price plunges as Bitcoin falls below the $62,000 mark.
By 7:00 am UTC on June 2, network stability was fully restored. Despite the fix, Bitcoin chart signals point toward volatility as investors weigh the long-term implications of such a significant vulnerability.
While the Zcash Foundation’s turnstile mechanism suggests the total supply is intact, founder Zooko Wilcox noted that the privacy features of the Orchard pool make it impossible to cryptographically prove that no exploitation occurred previously.
Uncertainty looms as macro and technical risks collide
The dual impact of strong U.S. labor data and the Zcash bug has left the cryptocurrency market searching for a stable floor. Bitcoin is now trading dangerously close to the $60,000 level. Traders are also noting a retreat in the “AI trade,” with tokens like HYPE falling 14%.
This suggests that capital is rotating out of speculative sectors as the reality of a resilient U.S. economy pushes the prospect of rate cuts further into the future.
The Zcash incident highlights a broader debate regarding the utility or obsolescence of privacy protocols. While the Zcash Foundation maintains there is no evidence of unauthorized value creation, the four-year window in which the bug existed has shaken confidence.
For now, the market remains focused on the upcoming Federal Reserve commentary, as the combination of high employment and technical fragility in major protocols keeps the pressure firmly on digital assets.
