Brent fell 5 percent on a peace process Tehran denies. Tokyo put its name on the yen.

The weekend's two headlines finally met an open market, and the market moved first on oil. Front-month Brent fell about five percent in early trading Monday, crossing the downside line this publication registered in advance for exactly this kind of morning. Two forces pressed the same direction at once: President Trump's claim that the parameters of an Iran deal are agreed and that talks resume today, and an OPEC+ decision that adds barrels in September. The selling was concentrated at the front of the curve, which is where war premium lives.

The claim under the move is disputed by the party it needs most. Hours after Trump's announcement, Iran's foreign ministry said Iran is "not currently negotiating" with the United States, and that its talks are with Oman over passage through the Strait of Hormuz. The market spent the morning pricing the hopeful side of that disagreement. The day's other headline needed no interpretation at all: Japan's finance ministry confirmed, in its own signed statement, that it bought yen Friday in coordination with the US Treasury. That is the first joint action by the two governments since 2011.

One caveat covers everything here: every price this morning is a pre-open capture, and the settlements render the verdicts tonight. Part of the reason a five percent break lands crude in the low $80s rather than the $90s is that the far end of the oil curve has spent months pricing weaker demand. The front carried the war premium. The back end kept pricing a weaker buyer.
