Bitcoin hit a seven-month low as CME’s June futures expired

Bitcoin fell to $5,774 on Bitstamp on June 29, 2018, its lowest price on that exchange since November 12, 2017, according to contemporaneous Reuters reporting. The decline carried bitcoin below $6,000 during a session that also marked the scheduled expiration of CME’s June bitcoin futures contract.

The two developments made June 29 a useful measure of the market’s condition at the end of a difficult first half. Spot bitcoin was testing levels last seen before the steepest phase of the 2017 rally, while a regulated, cash-settled futures market was completing one of its earliest quarterly expirations.

A severe intraday test

Reuters reported the $5,774 Bitstamp low and placed bitcoin at $5,891, up 0.7% at the time of its June 29 dispatch. Those figures were venue-specific observations captured during the session, not a universal closing price. Bitcoin traded continuously across exchanges, so prices and daily boundaries varied by platform and data provider.

CoinMarketCap’s historical snapshot labeled June 29 subsequently recorded bitcoin at $6,218.30, with a reported market capitalization of $106.47 billion and $3.97 billion of trailing 24-hour volume. The same snapshot showed a 5.08% increase over its rolling 24-hour measurement window. That apparent gain does not contradict the earlier Bitstamp low: it reflects a later observation, an aggregated methodology and a different comparison window.

The rebound from $5,774 to CoinMarketCap’s $6,218.30 snapshot level was approximately 7.7%, calculated as the difference between those two observations divided by $5,774. That calculation illustrates the intraday reversal but should not be treated as a venue-specific investment return because it combines a Bitstamp low with an aggregated snapshot.

The futures expiration

CME’s governing contract filing specified that its bitcoin futures represented five bitcoin per contract, were quoted in U.S. dollars and expired on the last Friday of the delivery month. Trading in the expiring contract terminated at 4:00 p.m. London time, with cash settlement based on the CME CF Bitcoin Reference Rate published for the final trading day.

June 29 was the last Friday of June 2018, making it the termination date for the June contract under those rules. CME had included June 2018 among the delivery months listed when the product was introduced in December 2017.

The expiration established an institutional reference point, but the surviving evidence does not establish that futures settlement caused the spot-market decline or subsequent recovery. Spot trading, position reductions, exchange-specific liquidity and broader risk sentiment could all affect prices. Temporal coincidence alone cannot isolate the effect of one derivatives expiration.

Why the date mattered

By June 29, bitcoin’s retreat was no longer a short correction from its December 2017 peak. Reuters described the Bitstamp print as the lowest since November 12, 2017 and reported that ether and XRP were also under pressure during the session. The breadth of the weakness made the episode a market-wide stress event rather than a move confined to one small token.

At the same time, the recovery captured in the later historical snapshot demonstrated why a single intraday print could not describe the full session. June 29 contained both a new multi-month low on Bitstamp and a sharp rebound in aggregated pricing.

Limits of the reconstruction

The exact market low depends on exchange coverage, currency pair and timestamp. Reuters supplied the contemporaneous Bitstamp observation; CoinMarketCap supplied a separate historical snapshot and rolling 24-hour metrics. CME’s filing verifies the contract design and expiration rule, but none of the cited records proves a causal relationship between expiration and spot prices. No later price history or later regulatory outcome is used to reinterpret what participants could know on June 29, 2018.
