Crypto Drops After U.S. Naval Blockade, Oil Spike

Crypto markets fell sharply on April 13 as the total market capitalization declined 27% from its January peak to $2.39 trillion. Bitcoin slipped below $71,000 and the sell-off erased roughly $61 billion in 24 hours, extending a pattern of weekend weakness into Monday trading.

The U.S. military began enforcing a naval blockade on Iranian ports on April 13. The action coincided with a rise in oil prices and a broad risk-off response that reduced demand for risk assets, including cryptocurrencies. Analysts also pointed to rising defaults in private credit and redemption requests exceeding $20 billion in the first quarter of 2026 as factors weighing on market sentiment. Weakness in global equity markets on Monday added to pressure on digital assets.

Technically, the total crypto market cap has been in a downtrend since late January, falling from about $3.29 trillion to $2.39 trillion. The market sits below the 0.618 Fibonacci retracement level at $2.46 trillion, which currently acts as resistance. Short-term support is near the 10-day simple moving average around $2.39 trillion. Deeper support is near the 0.786 Fibonacci level at about $2.27 trillion; a decline below that level could expose a full retracement target near $2.05 trillion. A daily close above $2.46 trillion would be needed to reverse the recent decline.

Bitcoin’s chart reflects the broader weakness. BTC traded near $71,023, under the 0.618 Fibonacci retracement at $72,359 calculated from a $60,016 swing low to a $97,925 swing high. If Bitcoin falls below $71,000, the next technical support is around the 0.786 level near $66,645, about a 6% drop from current levels. The 100-day simple moving average slopes downward at roughly $75,300; Bitcoin has not closed above that average since October 2025. A sustained daily close above the 100-day average would precede a test of the 0.5 Fibonacci near $76,662.

Not all tokens followed the broad sell-off. Dash rallied more than 100% over the prior week, rising from around $29 to above $47, then corrected about 12% to trade near $41.80. The 200-day simple moving average at approximately $46.49 capped the advance. Dash trades between the 0.618 Fibonacci level at $46.27 and the 0.786 level at $37.85. Trading volume spiked during the rally, indicating notable buying interest; failure to hold $37.85 would reverse the recent gains.

Market participants noted that selling has tended to intensify on Mondays after weekend liquidity gaps. The combination of the naval blockade, higher energy prices, private credit concerns and concentrated redemption flows coincided with the risk-off tone across traditional and crypto markets.

Fibonacci retracement levels and moving averages are common technical tools traders use to identify potential support and resistance. The 0.618 and 0.786 levels cited above are calculated from recent swing lows and highs and are being watched for signs of either a rebound or further retracement.
