油價一插，債市執到一日平安

原油琴晚已經做晒功夫。九月期油而家 $80.05，單日跌 $4.62 [11]——即係一日插咗成 5.5%，USO 跌 5.67% [11]——因為伊朗局勢降溫嘅消息，把戰爭溢價由能源度整個抽走 [1]。國債接棒：有講法話長債因為油價急插、加上日圓資金流嘅保證而轉強 [2]，不過我話你聽，當日 TLT 得 −0.02%，即係打和收場，所謂「長債轉強」其實喺數據度搵唔到支持。實情係 10 年息 4.686%、30 年息 5.231% [11]。股市反而行先——SPY +1.47% 到 758.05，QQQ +1.83% 到 700.59 [11]，指數收喺歷史高位附近 [1]，Amazon 市值破 3 萬億 [9]。金就唔肯認呢單嘢，GLD 只係浮上 0.15% 到 372.09 [7][11]。波幅期貨結構照樣淡定：現貨 VIX 15.86，前月期貨 17.85，contango 12.55% [11]。

今日入市要記住一件事：呢個係能源定價嘅反彈，唔係債務定價嘅反彈。發債嗰條數，一晚之間變過咩？冇。聯邦基金利率 3.63% [12]，30 年期就印住 5.231% [11]——160 點子嘅裂口，講緊全經濟嘅利率而家係債市話事，唔係議息會議話事。呢個分析框架今朝就係咁講明：冇一條可信、講得清清楚楚嘅回到 2% 嘅路徑，國債照樣跌返落去 [3]。財政部個交易台亦都拒絕咗華爾街提議嘅發債指引改動 [5]，而各國央行似乎好樂意企埋一邊，等債市自己做晒政策嘅粗重功夫 [6]。再挖深啲，通脹內裏仲衰過個標題：CPI 按年 3.73%，PPI 10.11% [12]。生產者同消費者價格之間 638 點子嘅楔子，你估係咩嚟？唔係邊際被壓扁，就係一條排緊隊等轉嫁嘅數——總之唔係通脹回落。核心 PCE 3.29% [12]，離目標仲有排。初領失業金 197k [12]，聯儲局想減息，連個藉口都冇。

日內偏好做好友。Contango +12.55% [11]，即係波幅 ETF 嘅轉倉機制日日喺度放長波幅嗰班人嘅血；IV rank 13.6，ATM IV 10.06% [11]；put/call 0.914 [11]，仲未去到見頂嗰種癲晒嘅極端。呢個分析框架之下，正 contango 就係「逢跌買」嘅格局：波幅抽升就淡佢，順住個勢行，但注碼要細——高位嘅自滿係脆弱，唔係安全，你話係咪咁㗎?

今日冇一線美國數據。製造業嗰份已經出咗，擴張速度係 2022 年以嚟最勁 [8]——呢個其實係鷹派數據，但股市當睇唔到。本週真正嘅戲肉喺星期五同埋下星期三。

今日關鍵位：

SPY 758.05 [11] — 守得住就繼續追歷史高位；失守 752 就打爆個補缺口
30 年息 5.231% [11] — 升穿 5.30%，油價嗰啲利好就畀發債壓力全部抵銷；股市嘅淡友線
10 年息 4.686% [11] — 4.70% 係轉捩點；跌穿 4.60% 先算confirm到啲買盤係真
WTI $80.05 [11] — 重返 $84.67（琴日個位）即係戰爭溢價返晒嚟；跌穿 $78 就延續通脹回落嘅憧憬
VIX 現貨 15.86 對前月 17.85 [11] — 現貨升穿期貨，偏好即刻反轉做淡友

要留意： Employment Situation，8月7日星期五，美東時間早上 8:30 [13]。初領失業金得 197k [12]，如果非農低過 10 萬、加上失業率抽升，呢個數就會逼到成個利率辯論重新開返。

扭轉偏好嘅嘢： 伊朗談判擺明破裂——呢個風險喺背景度一直未死 [10]——原油跳空重上 $84.67 [11]，contango 收窄甚至倒掛，今日嘅好友傾向就變咗聽日嘅淡友。仲有日圓嗰條腿都要睇實：個干預承諾 [4] 根本係瞄住美國孳息去嘅，一旦失手，30 年債就會拖住所有嘢一齊向下。
