Oil plunged 7.6% and stocks fell anyway, because markets are trading politics this week

The oil puzzle

Brent crude fell 7.6 per cent to $104.77 a barrel, and European natural gas fell with it, with TTF gas settling 8.7 per cent lower at a little under EUR95 per megawatt-hour. The proximate cause, according to both Emirates NBD and ING, was prospects for US-Iran negotiations reducing the geopolitical premium on oil, after the Iranian president said the government had been given more authority from the supreme leader to negotiate with the US and the US president answered no when asked whether he would strike Iran after the midterms. Gold rebounded 1.85 per cent, recovering from its lowest level in a year, as cheaper oil eased some inflation concerns weighing on gold. m:…7616 m:…7782

Normally cheaper energy lifts equities. It did not. The Nasdaq 100 lost 1.4 per cent, taking its decline from October's peak beyond 10 per cent, chipmakers shed 12 per cent over three sessions, and the S&P 500 fell 0.5 per cent, The US 10-year yield fell 3.5 basis points to 4.89 per cent, and the US Treasury cut its fourth-quarter borrowing estimate by $10 billion to $618 billion, with first-quarter borrowing projected at $800 billion. The oil move is not a growth signal but a geopolitical one, and geopolitical signals cut both ways. m:…7616

ING is explicit about the caveat: the US carried out strikes on Iran's Qeshm Island that Monday, and geopolitical risks remain elevated. Whether talks lead to sustained de-escalation is unresolved, and the market is pricing that uncertainty rather than the price of a barrel. A 7.6 per cent fall that leaves equities weaker is a market saying it does not yet believe the diplomacy. m:…7782

The election in the price

The second political input is domestic. US midterm voting began that day, and ING's foreign-exchange note frames the week around it: Democrats are widely expected to take the House, where they need a net gain of just four seats, the Senate is expected to be much closer, and prediction markets give the Democrats a 74 per cent chance of securing it. A Democratic clean sweep, ING argues, can put some pressure on the dollar. m:…7616 m:…7314

BNP Paribas explains why the election is about prices rather than personalities. Prices are up 28 per cent over five years, with housing up 31 per cent and food up 29 per cent, average hourly earnings grew 3 per cent year on year in September 2026, the slowest rate since 2018 and below inflation, and real wage earnings fell 0.7 per cent year on year in September. The household saving rate fell to 3.8 per cent in September, down 1.4 percentage points year on year, which BNP Paribas reads as households drawing on savings to offset price rises. Energy accounts for the entire gap between the September consumer price reading of 3.7 per cent and the pre-conflict level of 2.4 per cent, which is why an oil move and an election are the same trade this week. m:…7706

The institutional constraints matter as much as the result. BNP Paribas notes neither party is within reach of the thresholds required to override a filibuster or a presidential veto, and the federal deficit is expected to remain stable at 6.3 per cent of GDP in 2027, with the debt limit potentially reached as early as the first quarter of 2027. A Democratic sweep, the bank adds, could lead to increased congressional activism on regulation, on concentration in the AI industry, and on the knock-on effects on the cost of living from data centres and electricity, and on jobs. The market is pricing not just who wins but what a constrained winner can do. m:…7706

The trade-war question

The third political input is the EU-China relationship, where ABN AMRO asks whether a second China shock triggers a trade war and answers that it probably does not. Chinese vehicle and chemical exports to the euro area rose around 150 per cent and 140 per cent respectively between 2019 and 2024, Chinese companies received three to eight times more state aid than western firms between 2005 and 2024, and the IMF estimates the yuan is 17 to 25 per cent undervalued. The EU responded with tariffs of up to 45 per cent on Chinese electric vehicles in late 2024, and in early October agreed with China to cap hybrid car imports at 350,000 vehicles a year starting 1 December 2026. m:…7720

ABN AMRO's judgment is that mutual economic interests prevent escalation into a full-scale trade war, and that the EU will manage the shock through targeted tools rather than blanket confrontation. The EU's Critical Raw Materials Act already stipulates that by 2030 no more than 65 per cent of annual consumption of strategic raw materials should come from a single third country, and a Diversify EU instrument is expected by the end of 2026. Germany's policy shift toward China is cited as the most remarkable part of the change. The unresolved question is whether the hybrid-car cap model can be applied to machinery and chemicals without triggering retaliation. m:…7720

Put together, the week reads as a single pattern: stronger data sits alongside weaker equities, cheaper oil alongside elevated risk, and a cost-of-living election alongside a trade negotiation. Professionals watching only the commodity price will miss the trade: the price moved on diplomacy, equities moved on elections and chip weakness, and the trade question turns on whether targeted tools hold. What matters next is the Senate results, the December hybrid cap, and whether diplomacy survives its first week. m:…7616
