美國總統川普於 4 月 22 日宣布延長對伊朗停火期限，在巴基斯坦陸軍參謀長及總理的請求下，美方將等待伊朗提交統一方案後再推進，同時繼續維持海上封鎖並保持戰備狀態。伊朗拒絕出席原定在伊斯蘭堡的新一輪談判，霍爾木茲海峽再度關閉。比特幣反彈至 76,000 美元，分析師 DonAlt 將此視為決定後市走向的關鍵早期警示位。
川普停火延長的外交轉折：從強硬備戰到等待統一方案
就在 4 月 22 日稍早，川普接受採訪時還表示並不想延長停火，並稱如果協議無法達成，美軍已「準備好」對伊朗發動打擊。短短數小時後，川普卻宣布延長停火，被美聯社和《華盛頓郵報》等媒體指出發生在談判前景急劇惡化之後。
伊朗拒絕出席談判的關鍵原因在於，德黑蘭指控美方違背了透過巴基斯坦斡旋形成的十點框架，並在伊斯蘭堡首輪會談中提出違背框架的要求。伊朗方面稱在當前條件下赴會「只是浪費時間」，核濃縮能力和導彈計畫屬伊朗內政，不接受任何外部干涉。副總統萬斯原定率團赴巴基斯坦的行程亦被取消。
霍爾木茲海峽再度關閉：油價承壓能源市場波動
與伊朗伊斯蘭革命衛隊有關聯的半官方塔斯尼姆通訊社宣布，霍爾木茲海峽將關閉直至另行通知，理由是美國持續扣押與伊朗相關船隻（包括油輪 M/T Tifani 號）。霍爾木茲海峽正常情況下每天處理約 2,100 萬桶石油，約佔全球供應量的 20%。海峽關閉已觸發不可抗力聲明，布蘭特原油回落至每桶 95 美元附近。
值得注意的是，美國財政部數據顯示 2025 年外國投資者仍購買了創紀錄的 1.55 兆美元美國金融資產，顯示全球資本依然將美國視為核心避風港，地緣政治緊張與資本流向形成鮮明對比。
比特幣技術分析：76,000 美元早期警示位的雙向意涵
分析師 DonAlt 指出，76,000 美元代表上個月的高點，是對當前突破能否持續的第一個考驗。跌破此位並不會終結漲勢，但預示著早期疲軟。週線開盤價位於 70,000 美元，代表整個上漲行情的起點，跌破此水準意味著上漲動能完全喪失。
向上的路線圖方面，月線圖上 82,000 美元是下一個阻力位，阻力預計較小；此後進入 86,000 至 94,000 美元的震盪區間，95,000 美元是分析師建議的潛在獲利了結目標位。
常見問題
川普延長停火的具體條件是什麼，對市場意味著什麼？
川普表示，停火延長的前提是等待伊朗政府提交「統一方案」並完成相關磋商，美軍封鎖同時維持。市場解讀為短期內直接衝突升級的可能性有所下降，但外交前景高度不確定，任何伊朗談判破裂或美軍新行動的信號，都可能迅速逆轉風險資產情緒。
霍爾木茲海峽再度關閉對加密市場有何影響？
海峽關閉推動油價上行，加劇通膨預期，對包括比特幣在內的風險資產構成下行壓力。歷史上，能源價格急劇波動往往伴隨著加密市場波動率上升，尤其是在市場關注聯準會貨幣政策走向的時期。
比特幣分析師如何解讀 76,000 美元的技術意義？
DonAlt 將 76,000 美元定義為「早期警示位」——跌破此位預示短期動能疲軟但不終結漲勢；最關鍵支撐在 70,000 美元，跌破意味著整輪上漲動能喪失。向上需突破 82,000 美元才能打開通往 95,000 美元的路徑。
