One rejection sent oil up more than 4% intraday, and yields and stocks wobbled right after
🎧 Post Summary
📌 1-Minute Summary
U.S. President Donald Trump formally rejected Iran’s 7-day plan to reopen the Strait of Hormuz, and markets reacted in a chain within a day. In London trading on the 28th, Brent crude rose nearly 4% intraday to the $108 range, then pared gains on hopes for more U.S.-Iran talks and settled at $105.28, up 0.92%. Higher oil stoked inflation worries and pushed the U.S. 10-year Treasury yield up to 5.241%, its highest level since June 2007. On Wall Street, the Nasdaq fell 0.92%, the S&P 500 fell 0.77% and the Dow fell 0.67%. In Seoul on the 29th, KOSPI closed down 0.27% at 6,870.81 for a second straight decline, while KOSDAQ rose 0.38% to 849.80. Iran says the door to negotiations remains open and Washington expects more talks this week, so oil, yields and stocks may keep moving together on negotiation headlines.
KOSPI dropped 2.7% yesterday and slipped again today. The cause is not one thing but three linked steps: Iran talks, then oil, then yields, then stocks. Here is how the chain played out.
1. Iran’s ‘7-Day Plan’ and Trump’s Rejection
According to Seoul Economic Daily, citing foreign wire reports, Iran passed word through mediators that it would reopen the Strait of Hormuz and return to nuclear talks if the United States kept three conditions for seven days. The conditions are an end to hostilities on all fronts including Lebanon, the release of some frozen Iranian assets, and the lifting of the naval blockade and oil sanctions.
On the 26th (U.S. time), President Trump told reporters at the White House, “I reject their proposal.” His explanation was that Iran is in a losing position and wants a quick deal. The next day, however, he told Axios he expects more talks with Iran this week, and said the deal Iran wants is not the deal he wants. Washington is demanding concessions from Iran on the nuclear issue.
Iran has not closed the door either. Foreign Minister Abbas Araghchi said he had confirmed Trump’s first reaction but had not received an official U.S. reply through mediators, and that Iran would wait for Washington’s final position. He also stressed that Iran’s basic rights and its preconditions for reopening the strait are not negotiable. Indirect mediation through Qatar is continuing.
Views on the surrounding picture differ. Financial News reported that the volume of crude passing through the Strait of Hormuz has recovered to about 60% of its pre-war level, tilting the negotiating initiative toward the United States. On the other hand, the Wall Street Journal reported that Trump has told aides he expects U.S. strikes on Iran to resume after the November midterm elections, which markets are treating as a risk factor.
2. Oil: Up More Than 4% Intraday, a Small Gain at the Close
When news of the rejection spread, November Brent futures in London briefly hit $108.48 a barrel on the 28th, the highest in about two weeks. Expectations that Qatari mediation could keep U.S.-Iran talks going then cut the gain sharply. Brent settled at $105.28 (+0.92%) and WTI at $92.60 (+0.21%).
Bloomberg reported that Brent is up more than 70% this year and could post a third straight monthly gain. With oil swinging as much as 4% intraday on a single negotiation headline, volatility itself, rather than direction, is the defining feature right now.
3. Yields: The 10-Year at 5.241%, Highest Since 2007
High oil fed inflation worries and led to a bond selloff. The U.S. 10-year Treasury yield rose as high as 5.272% before closing at 5.241%, and the 30-year yield climbed as high as 5.561%. Rate futures priced in a 70.3% chance that the Federal Reserve raises its policy rate by another 0.25 percentage point in October. The dollar index rose to 101.219, and spot gold fell 3.61% to $4,131.53 an ounce.
Fed Governor Lisa Cook said she expects inflation pressure to persist for the next several months because of AI-related demand and high oil prices, though she stopped short of saying another hike is needed. Jack Ablin, chief investment strategist at Cresset Capital, described a chain in which Iran pushes oil higher, oil pushes inflation higher, and inflation pushes yields higher.
4. Stocks: Wall Street Lower Across the Board, KOSPI Near 6,870
On Wall Street on the 28th, the Dow closed down 0.67% at 51,481.51, the S&P 500 down 0.77% at 7,683.69 and the Nasdaq down 0.92% at 26,820.38. Every ‘Magnificent 7’ stock except Nvidia fell, while Nvidia rose on news of a $150 billion share buyback.
On the 29th, KOSPI opened 45.33 points lower at 6,844.41 and briefly slid into the 6,700s before trimming losses to close down 18.93 points (0.27%) at 6,870.81. Individuals were net buyers, but foreign investors sold heavily. Samsung Electronics rose 0.93% to 272,500 won, cushioning the index, while SK hynix slipped 0.17% to 1,765,000 won. Non-semiconductor names were sold harder: LG Energy Solution fell in the 3% range, and Hyundai Motor and Samsung Biologics fell in the 1% range.
KOSDAQ gained 3.22 points (0.38%) to close at 849.80. Semiconductor materials, parts and equipment stocks lifted the index late in the session, and Money Today said news of Samsung Electro-Mechanics’ plant expansion and a large supply contract fueled expectations of spillover benefits.
Investor Notes
- Headline volatility: News of talks failing and news of talks continuing arrived on the same day, and oil moved as much as 4% intraday. Rather than betting on a single scenario, it makes sense to keep both outcomes in mind.
- Two sides of higher yields: Rising yields weigh on stock valuations, but Ablin pointed out that bonds have become quite attractive relative to stocks for the first time in 20 years. The possibility of money shifting between the two is worth watching too.
- Uneven moves across stocks: On the same day KOSPI fell and KOSDAQ rose, and large-cap semiconductors and non-chip stocks diverged. A single index is a poor guide to the whole market.
- What to check next: This week’s additional U.S.-Iran talks and upcoming U.S. inflation data could steer oil and yields.
In short, for a second day Iran negotiation news moved oil, oil fed inflation fears and pushed yields up, and higher yields came back around as a weight on equities. Whether talks progress or worries about renewed conflict after the midterms grow could turn all three measures in the same direction.
