O Estreito de Ormuz está fechado, com diversos países enfrentando escassez no fornecimento. O Goldman Sachs estima que uma perda de 14,5 milhões de barris por dia da produção do Golfo Pérsico está drenando os estoques globais de petróleo a um ritmo recorde de 11 a 12 milhões de barris por dia até abril.

Enquanto o mundo enfrenta a diminuição de petróleo, o Irã encontra dificuldades para armazenar o volume de óleo cru que não pode mais exportar.

Como o bloqueio dos EUA no Estreito de Hormuz alterou o fluxo de petróleo do Irã?

De acordo com uma proclamação presidencial, o Comando Central dos EUA (CENTCOM) impôs um bloqueio a todo o tráfego marítimo que entra ou sai de portos iranianos a partir das 11h, horário de Brasília, em 13 de abril.

Nas semanas seguintes, as exportações de óleo cru iraniano despencaram, caindo de 1,85 milhão de barris por dia em março para cerca de 567 mil barris diários.

Isso representa uma redução de quase 70%, segundo informou a Bloomberg, citando a empresa de inteligência marítima Kpler. Os analistas relataram que nenhum navio-tanque conseguiu furar o bloqueio próximo ao Estreito de Hormuz.

Com as exportações interrompidas, o Irã fica sem opções para estocar óleo cru. Segundo a Kpler, restam apenas de 12 a 22 dias de capacidade disponível nos tanques para armazenamento.

O Goldman Sachs Group Inc. afirmou na última semana que o Irã já reduziu sua produção de óleo cru em cerca de 2,5 milhões de barris por dia. A limitação de espaço para armazenagem aumenta a probabilidade de Teerã ser obrigado a cortar mais 1,5 milhão de barris diários até meados de maio.

Os efeitos geram impacto em toda a região: países vizinhos produtores, como a Arábia Saudita, Iraque, Kuwait e os Emirados Árabes Unidos também tiveram que reduzir a produção desde o início do conflito em 28 de fevereiro.

While the surviving IRGC Leaders are trapped like drowning rats in a sewage pipe, Iran’s creaking oil industry is starting to shut in production thanks to the U.S. BLOCKADE.

Pumping will soon collapse.

Apesar disso, Teerã não sentirá imediatamente o impacto na receita. Os embarques de óleo cru ao mercado chinês levam em torno de 2 meses para chegar ao destino. Os compradores levam mais dois meses para quitar as faturas. Esse atraso empurra o prejuízo financeiro para um intervalo de três a quatro meses, mesmo enquanto o armazenamento físico se esgota.

On April 26, a significant Bitcoin transaction was observed as a whale moved 300 BTC into a centralized exchange (CEX) after a two-year hiatus. According to BlockBeats On-chain Detection, the whale had originally withdrawn these 300 BTC from another CEX three years ago when the price of Bitcoin was $19,329. This transaction has resulted in a profit of $17.6 million for the whale.

Bitcoin's price decreased by approximately $100, reaching $77,351 late morning on the U.S. East Coast. According to NS3.AI, this movement occurred after U.S. President Donald Trump announced the cancellation of a planned trip to Iran by Steve Witkoff and Jared Kushner. Witkoff and Kushner were anticipated to visit Pakistan for a new round of discussions involving Iran. The modest decline indicates that markets perceive this development as a short-term risk signal.

Key Takeaways
Bitcoin is trading around $77,500–$78,500, stuck in a tight range after failing to clear $80,000 on Wednesday, with futures open interest falling over 6% to 744,300 BTC in 24 hoursNegative funding rates and a flipped negative CVD signal rising bearish short positioning in derivatives marketsBitcoin's 30-day implied volatility index (BVIV) has dropped to 42%, its lowest since January 31, with ETH's IV also hitting a multi-month low below 65%Zcash (ZEC) stands out with futures open interest up 7.5% to a 10-day high and 24-hour trading volume surging 80%, boosted by a Robinhood listingThe CoinDesk Memecoin Index was the only major benchmark in positive territory on Friday; DeFi tokens continued to suffer in the wake of the $290 million KelpDAO exploit
Crypto markets shifted into a cooling phase on Friday as Bitcoin held a tight range between $77,500 and $78,500, with derivatives data pointing to leverage unwinding and a short-term loss of bullish momentum following the failed breakout attempt near $80,000 earlier this week.
Despite the stall, the broader April trend remains constructive. Bitcoin has printed a series of higher highs and higher lows through the month and is on track for its best monthly performance since November 2024, up approximately 14.3% month-to-date.
Leverage Comes Off, Bears Reassert in Derivatives
Bitcoin futures open interest declined by over 6% in 24 hours to 744,300 BTC, a clear signal that traders are reducing leveraged exposure rather than adding to positions at current levels. The 24-hour open interest-adjusted cumulative volume delta has flipped negative, indicating sellers are hitting the bid more aggressively than buyers are lifting the ask. Annualized perpetual funding rates have also turned slightly negative, reflecting a shift toward net bearish short positioning in perpetuals.
Options markets reinforce the cautious tone, with risk reversals on Deribit continuing to show a bias for put options across all timeframes -- a sign of persistent demand for downside protection and upside volatility selling via covered calls.
One constructive signal within the derivatives data: Bitcoin's 30-day implied volatility index BVIV has dropped to 42%, its lowest level since January 31, while Ethereum's equivalent has dipped below 65%, also a multi-month low. Falling implied volatility alongside range-bound prices suggests the market views the current pause as a consolidation rather than a reversal, with investors pricing reduced near-term risk rather than accelerating downside.
Macro Backdrop Stays Mixed
US stock futures were split on Friday, with Nasdaq 100 futures rising 0.5% on the back of strong tech earnings while S&P 500 futures slipped marginally. The Dollar Index was little changed despite President Trump confirming a three-week extension of the ceasefire between Israel and Lebanon -- the dollar had fallen roughly 0.5% when the ceasefire was first announced on April 16.
Zcash Breaks Out on Robinhood Listing
While most of the major crypto derivatives markets saw lackluster activity, Zcash (ZEC) was a clear standout. Futures open interest in ZEC climbed nearly 7.5% to a 10-day high of 1.88 million tokens, while 24-hour trading volume surged 80%. The token boasts one of the strongest positive CVD readings in the market alongside positive funding rates, pointing to sustained aggressive buying and net bullish positioning. ZEC gave back 0.5% of its gains on Friday but remains up more than 7% over the past 24 hours, driven by Thursday's listing on retail trading platform Robinhood.
Altcoins Mixed, DeFi Sentiment Remains Soft
Broader altcoin performance was subdued. Futures tied to Ethereum, Solana, and XRP saw lackluster trading over the past 24 hours. The CoinDesk Memecoin Index (CDMEME) was the sole major benchmark in positive territory on Friday, posting a gain of less than 0.2%. The DeFi Select Index and Computing Select Index each fell approximately 1%.
DeFi tokens Lido (LDO) and Morpho led sector losses, falling between 3% and 3.8% since midnight UTC as sentiment continues to be weighed down by the fallout from last weekend's $290 million KelpDAO exploit.
CoinMarketCap's Altcoin Season index ticked back up to 39 out of 100, suggesting some speculative rotation into altcoins as Bitcoin remained range-bound -- though the reading remains well short of the 75+ threshold that typically signals a full altcoin season.

According to Foresight News, Bancor has filed a lawsuit against Uniswap, accusing it of infringing on a patent from 2017. This patent covers the core structure for automated on-chain token swaps without a centralized intermediary. The lawsuit, filed in the U.S. District Court for the Southern District of New York, seeks unspecified damages.

The legal action is initiated by the Bprotocol Foundation, a nonprofit supporting the development of the Bancor protocol, and LocalCoin Ltd., the original developers of Bancor. They allege that Uniswap's protocol is built on Bancor's patented constant product automated market maker (CPAMM) infrastructure.

Bancor invented the CPAMM model in 2016 and developed a mechanism for permissionless on-chain transactions via smart contracts. The protocol released a white paper and filed a U.S. patent application in 2017. That same year, Bancor obtained two patents and launched the first decentralized exchange (DEX) based on the CPAMM model.

The lawsuit claims that Uniswap's original protocol, launched in November 2018, used the same CPAMM design without authorization. Bancor accuses Uniswap of deploying its intellectual property without consent, thereby "profiting unlawfully."
