Predicting when the next crypto bear market will occur

When will the next crypto market bear market begin?

The best answer isn’t a specific date, but rather a period of high risk. The risk associated with the next bear market has increased, and the end of 2026 is a critical time to confirm this trend.

The fourth halving of Bitcoin occurred on April 20, 2024. Historical patterns show that after the halving, when the rally becomes stronger, the market tends to become more vulnerable. As of October 13, 2026, the trading price of Bitcoin was around $83,516. This means investors no longer need to analyze the market conditions during earlier cycles.

A useful prediction model should take into account market cycle analysis, trend structure, profitability on the blockchain, ETF inflows, macro policies, and investor behavior. The goal isn’t to predict exactly when the crypto bear market will occur, but to understand how to respond when probabilities shift enough to reduce risks.

How can we define the start of a bear market?

The most likely start of the next crypto bear market would be after Bitcoin fails to recover from its main trend level. At the same time, there would be a decrease in ETF demand, altcoins would collapse faster than Bitcoin, and blockchain data would show widespread liquidations turning into actual losses. If we follow the traditional framework of Bitcoin halvings, then the high-risk period after the 2024 halving has already begun. Therefore, we need to focus on the period from the end of 2025 to 2026, rather than distant future events.

This doesn’t mean that every decline in cryptocurrency prices indicates a bear market. There are often sharp drops within bull markets, especially after leverage has accumulated. A true bear market is different: the momentum of the rebound weakens, liquidity moves away from high-risk assets, long-term investors sell off their holdings during periods of strength, and trends fail to translate into sustained demand. The halving cycle remains important, but it’s no longer sufficient by itself. Bitcoin’s supply plan continues to be a key factor in many crypto market trends. Block rewards are halved every four years; after the halving in April 2024, the current reward is 3.125 BTC. The next halving is expected to occur in 2028. Historically, halving cycles have helped define bull and bear markets, as reduced issuance combined with improved liquidity led to increasing demand. But now, the market is more institutionalized. On January 10, 2024, the United States approved exchange-traded products related to physical Bitcoin, creating new channels for demand that weren’t available in earlier cycles. This changes the way we analyze markets: ETF inflows can prolong the rebound by absorbing supply, while continuous outflows can accelerate declines. In other words, the cycle clock is still important, but it now competes with factors like capital flows, macro interest rates, regulatory environments, and professional portfolio rebalancing. When will the next crypto bear market start?

If you ask, “When will the next bear market begin?” the most reliable answer is: It’s more likely that the signals indicating a bear market will appear over several months, rather than at a clear calendar milestone. For risk management purposes, if Bitcoin remains below its previous highs, ETF demand decreases, and macroeconomic conditions worsen, then November 2026 to early 2027 could be a reasonable time for confirmation.

However, if Bitcoin has already reached its cyclical peak and continues to decline, some analysts might predict the start of a bear market sooner. This difference stems from different definitions. Traders might call it a bear market when the main moving averages fall below certain levels; long-term investors might wait until there are lower highs within a few months; on-chain analysts might wait until there is actual loss and declining profitability among various groups.

One practical way to handle this uncertainty is to consider three possible scenarios:

• Early bear scenario: The cyclical peak has already passed, and 2026 will be the first full year of a bear market.
• Transition scenario: The market is transitioning from the late stages of a bull market to a bear market. Confirmation still depends on price structures and capital flows.
• Delayed scenario: Institutional demand and loose liquidity delay the next bear market, leading to an upward trend before a final collapse occurs.

The transition scenario is usually the most valuable, as it avoids making binary judgments. You don’t need to predict exact dates to manage your positions wisely.

What are the most important indicators of a bear market at present?

The most important indicators of a bear market include trends, profitability, liquidity, leverage ratios, and participation levels. No single indicator is reliable; warning signals become more significant when multiple indicators deteriorate simultaneously.

Glassnode’s MVRV framework compares market capitalization with actual value. Historically, the high MVRV regions have been associated with profit-taking actions at the end of cycles, while the low MVRV regions are often related to the bottom of bear markets and accumulation phases. Glassnode also emphasizes the synergy between MVRV, aSOPR, Puell Multiple, and reserve risks. The consistency among different investor behavior measures is more important than isolated signals.

Use the following checklist to distinguish between normal fluctuations and potential crypto bear markets:

• Bitcoin trends: The price has remained below the 200-day moving average for several weeks, with further declines in high points.
• Market breadth: There is less activity in coins participating in rallies, and altcoins have lost momentum before Bitcoin.
• ETF flows: Flows have slowed down, become inconsistent, or even turned into continuous outflows during attempts at rallies.
• On-chain profitability: MVRV, NUPL-style profitability, and profit-and-loss trends indicate that holders are shifting from profits to losses.
• Leverage ratios: Funding rates and open positions remain high, while prices stop rising, paving the way for forced liquidations.
• Stablecoin liquidity: 新的购买力停滞，使得反弹依赖于轮动而非新资本。
• 叙事疲劳：强劲的新闻产生短暂的脉冲，而不是持续的趋势延续。

单个红色标志是警告。四个或五个同时闪烁则是制度性转变的警告。

机构资金流可以延缓或加深下跌

本周期有所不同，因为机构不仅是旁观者，更是市场结构的一部分。Coinbase Research指出，2026年9月美国现货BTC ETF需求保持正值，当月流入约26亿美元，同时山寨币未平仓合约主导地位也上升。

这在两个方向上都至关重要。积极的ETF需求可以缓和抛售，因为受监管的产品继续吸收供应。但如果这些资金流逆转，同一渠道可以快速传导避险行为，特别是当基金经理同时减少股票、高贝塔科技股和加密资产的敞口时。

机构参与也可能使下一个熊市起初看起来不那么剧烈。市场可能不会突然崩溃，而是缓慢下行，流动性从较小代币旋转至比特币。这可能会掩盖表面下的压力，直到山寨币的下跌幅度变得严重。

宏观条件是压力阀

加密货币仍然是对流动性敏感的一类资产。当利率上升时，现金和短期债券变得更具竞争力，杠杆成本更高，投机性资产通常面临更严峻的条件。

美联储于2026年9月16日将联邦基金目标利率范围提高至3.75%–4.00%，其会议纪要显示，大多数参与者认为，如果 incoming 数据支持，年底前再次加息可能是适当的。

对于加密市场而言，这意味着宏观政策既可以确认也可以挑战熊市论点。更高的利率路径可能会给估值带来压力，并减少对杠杆的胃口。如果政策意外转向宽松，尤其是如果ETF资金流保持正值且比特币守住关键支撑位，周期可能会延长。

实用的风险计划胜过完美的预测

试图准确预测下一个熊市的确切开始时间会导致过度自信。更好的方法是定义如果证据恶化你将采取什么行动。

考虑一个简单的响应计划：

• 定义你的熊市界限：结合比特币趋势、投资组合回撤和宏观条件，而不是情绪。
• 首先降低杠杆：杠杆会将正常的加密货币价格下跌变为被迫退出。
• 从弱势资产重新平衡：周期末期的市场往往先惩罚缺乏流动性的山寨币，然后才是主要资产。
• 保留现金储备：如果波动性激增，现金或稳定流动性给你选择权。
• 每月审查，而非每小时：A bear market develops during a period of failed recoveries, and it’s not just due to one bad trading day. This is particularly important for investors who hold a combination of Bitcoin, Ethereum, and other small tokens. The next bear market may not affect all assets at the same rate. When higher-risk sectors begin to collapse, Bitcoin might still seem stable. The best answer to the question “when will the next crypto bear market start?” is to focus on the confirmation window around the end of 2026. But we should remain cautious from now on. The halving cycle of Bitcoin, current price structures, institutional ETF activities, profitability on the blockchain, and Federal Reserve policies all suggest that the market requires more caution than in previous cycles. Don’t rely on a single prediction or indicator. Create a dashboard to define your risk triggers, and make adjustments before the market reaches a consensus that a bear market has begun.
