Monday opened with a genuine supply shock and closed with a diplomatic riddle. WTI reached $84.59 intraday before Iran signalled it had received mediation proposals, pulling the contract back to around $82.50. The overnight gap from Friday's $81.78 close held without being filled - the minimum condition for the continuation thesis to survive. Then, as London moved toward its afternoon close, the Yemeni Houthis declared a maritime embargo against Saudi Arabia, effective immediately. That announcement has the potential to close the bypass route Saudi Arabia had been using to redirect exports away from the disrupted Strait of Hormuz. Markets did not fully reprice it. Oil sits at $82.50. The diplomatic signal is doing heavy lifting to keep it there, and that will not last if the Houthis move from declaration to active interdiction.
Gold held its $3,960 floor for the second consecutive session. Canada's June CPI came in at 2.8%, with a core measure dropping below 2% for the first time in nearly six years - the most constructive data point the USD/CAD short has seen in this cycle. And Andy Burnham entered Downing Street, but appointed John Healey rather than Mahmood as Chancellor, catching sterling positioning off guard. The week's real trades are still forming. The ECB on Thursday and UK CPI on Wednesday are the triggers. The full briefing explains which levels hold the keys, where the overnight positioning risk lies, and what a Houthi enforcement action would mean for USD/CAD, gold, and the franc.
