The Gulf spent the week fighting over tankers. US Central Command said it disabled three Iranian crude tankers on September 5, after Iranian missile launches at two US Navy ships, and destroyed five more on September 8 and 9, four in the Gulf of Oman and one near Kharg Island. Iran claimed ballistic-missile attacks on a US carrier and a warship, which CENTCOM said were evaded, and later claimed strikes on a Jordanian base hosting American aircraft. Houthi forces publicly claimed the September 7 strike on Saudi Aramco's Jazan refinery, and a Saudi coalition spokesman confirmed 73 wounded. By Wednesday the Revolutionary Guard navy had expanded its declared prohibited zone and warned tanker crews near Kuwaiti and Bahraini docks to abandon ship.

Crude repriced hard, and it repriced unevenly. Front-month Brent settled at $96.28 on September 4 and at $104.61 on Friday, a weekly gain of about 8.7%, by way of a $101.21 settle on Wednesday that was the first triple-digit close since July and a $107.63 settle on Thursday that is the highest in our tracking record. The December 2027 contract, over the same stretch through Thursday, went from $76.78 to $78.23. The front end took roughly eleven dollars. The far end took a dollar and a half.

Then the data took the tape back. August producer prices accelerated to 5.4% year on year from an upwardly revised 4.8%, and our own estimate of the odds on a quarter-point Fed hike on September 16 jumped 10.7 points in a single session to 75%. Friday's consumer price index came in close to forecast, oil eased on word that Iran and its Gulf neighbors may meet in Oman on Monday, and stocks rallied into the close of a losing week. Gold finished lower for a third straight week.

The week, sector by sector

Oil and energy:

WHERE IT STANDS
Front-month Brent settled Friday at $104.61, down 2.8% on the day and up about 8.7% on the week, against $96.28 the previous Friday, both on the November 2026 contract. Thursday's $107.63 settle is the highest front-month print in our tracking record. West Texas Intermediate settled at $102.48 on Thursday against $91.48 on September 4. December 2027 Brent settled at $78.23 on Thursday against $76.78, leaving $29.40 between the front contract and the far end. OPEC+ held October output unchanged at its September 6 meeting, keeping about 2 million barrels a day of cuts in place; the group meets again on October 4.

WATCHING
Whether the front holds a triple-digit settlement through a week without a new headline. Two institutional forecasts moved in opposite directions on the same tape. OPEC's September monthly report cut 2026 demand growth to 0.38 million barrels a day, a fifth consecutive downward revision. The US Energy Information Administration raised its Brent path to about $90 a barrel for the second half of 2026 and $91 for the full year, falling to $74 in 2027; that outlook closed its forecast on September 3, before most of this week happened.

Iran and the strait:

WHERE IT STANDS
CENTCOM said US forces disabled three Iranian tankers on September 5 and destroyed five more on September 8 and 9. The Revolutionary Guard navy expanded its declared prohibited zone on September 9 and warned crews near Kuwaiti and Bahraini docks to abandon ship. The traffic reflects it. Lloyd's List puts Hormuz transits near 75 a week on its conflict-window measure, against a pre-war baseline around 100 vessels a day, and the tanker rate on the Middle East Gulf to China route reached a historic high near $760,000 a day. Those two traffic figures are quoted on different windows and different units, so read them as scale rather than as a ratio.

WATCHING
Oman is trying to seat Gulf Cooperation Council foreign ministers and Iran together in Salalah on Monday, which would be the first such gathering since the war began. It is not yet confirmed, and the two sides describe it differently: Oman frames it as regional understanding, Tehran as a discussion of the safe-shipping routes it agreed with Oman last month.

Interest rates and the Fed:

WHERE IT STANDS
Our own estimate of the odds on a quarter-point hike at the September 16 meeting held at 62.1% from September 5 through September 8, stood at 64.3% going into Thursday, and jumped to 75.0% once August producer prices printed at 5.4% year on year against an upwardly revised 4.8%. Friday's consumer price index matched the consensus at 3.4% year on year and 0.4% on the month, with the core measure a tenth above forecast. CME's FedWatch tool showed hike odds near 90% after it.

WATCHING
The FOMC decides Wednesday, September 16. One correction belongs here, because we published the opposite. We had described these odds as frozen through the shooting war. On a consistent settlement basis they were never quite frozen: the series carried a 2.2 point rise across the escalation before the prints arrived. The data moved it far more than the war did. That is a difference of degree, and it is all this evidence supports.

Gold and silver:

WHERE IT STANDS
Gold settled Friday at $4,408.90 against $4,476.60 the previous Friday, on the front-month COMEX contract, a third consecutive weekly decline. Silver settled at $65.19 against $66.748. Neither path was a straight line. Wednesday put gold at $4,460.70 and silver at $68.646, the highest silver settle in our tracking record, cutting the gap to our $70 line to $1.35. Thursday erased that: gold fell $53.40 and silver fell $3.72, a 5.4% break in a single session.

WATCHING
Our $4,400 durability line for gold, which Thursday cleared by $7.30 and Friday by $8.90. The give-back line that would open a full review of the position sits at $4,300, unmet by $108.90. The week did not tell us what broke the metals, and the section below explains why we cannot say.

Europe and the ECB:

WHERE IT STANDS
The European Central Bank raised its three policy rates by a quarter point on Thursday, taking the deposit facility to 2.50%, the main refinancing operations to 2.65% and the marginal lending facility to 2.90%, effective September 16. It was the second increase of 2026 and President Lagarde described it as unanimous. The bank revised its inflation forecasts up to 2.5% for 2027 and 2.1% for 2028, and raised growth to 0.9% this year. Euro-area consumer inflation ran 3.3% last month, a three-year high.

WATCHING
Whether an energy shock priced at the front of the oil curve keeps lifting a central bank's medium-term forecasts. It did this month. A supply-risk premium that stays confined to prompt barrels should not do that for long, and this one has now done it twice.

Japan:

WHERE IT STANDS
USD/JPY closed at 156.26 on September 4 and traded near 153.46 on Wednesday, a near-seven-month high for the yen, before backing up toward 154 by Friday morning as the dollar firmed on the producer-price print. A firmer yen on the week. The ten-year Japanese government bond yield closed Thursday at 2.92% on the Ministry of Finance's own published series, 8 basis points under the 3% line it had briefly closed above a week earlier.

WATCHING
The Bank of Japan meets September 17 and 18 and is widely expected to raise its policy rate to 1.25%. The gap that matters for the carry trade is wide: 1.00% against a Fed target range of 3.50% to 3.75%, roughly 250 to 275 basis points. Both central banks are now expected to move in the same week, which leaves the direction of that gap ambiguous. A durable compression of it would strengthen the repatriation case. A re-widening would weaken it.

Russia and Ukraine:

WHERE IT STANDS
An informal truce covering the capitals, in place during a US envoy visit, ran out on September 8. The night it expired, Ukraine's air force reported 2 ballistic and 31 cruise missiles plus 142 drones neutralized, the heaviest missile mix of this series. The next night it reported Iskander-M and Banderol missiles plus 196 drones, of which 165 were downed or suppressed, and Ukrenergo reported new power outages in five regions. We also corrected our own record this week: an attack on Odesa-region energy infrastructure overnight into September 2, with outages spreading to four more oblasts, is confirmed at Ukrenergo, and it ends a run of nights without energy targeting that we had been carrying. Ukraine's president said eight Russian infrastructure facilities were struck in the 24 hours to September 10, including a refinery in the Yamalo-Nenets district and port facilities at Makhachkala.

WATCHING
The Russia and Iran sanctions vehicle in the House. The Senate passed it 86 to 11 on August 7. The freshest report we could reach, dated September 2, still showed no scheduled floor vote, and the reported window was the week of September 14.

US stocks and the capital cycle:

WHERE IT STANDS
The S&P 500 closed Friday at 7,656.98, up 0.9% on the day and lower on the week against 7,718.60 on September 4; Wednesday's 7,591.70 was a third straight decline. COMEX copper settled at a record $6.89 a pound on Wednesday. And the capital cycle underneath both picked up a new source of funding: of nine companies holding letters of intent under Commerce's $2.013bn quantum program, four had signed definitive agreements by September 10, each of them giving Commerce a minority equity stake as a condition.

WATCHING
Whether a policy rate moving up changes what investors will pay for that cycle, now that part of it is being underwritten by the state rather than by the market. Copper's record carries a competing reading worth naming: datacenter demand and a decline in global mine output are one story, and purchases pulled forward ahead of the November 10 tariff cliff are another. The second one reverses.

A shooting war at the front of the curve

Start with the sequence, because the price action tracks it closely. On September 5 CENTCOM said it disabled three Iranian crude tankers, off Kharg Island, near Jask and in the Gulf of Oman, after Iranian missile launches at two US Navy ships. That resolved a question we had left open a week earlier about unattributed explosions near Kharg: the strikes hit tankers rather than the terminal. Iran answered with claimed missile attacks on a US carrier and a warship, which CENTCOM said were evaded. On September 7 Saudi Aramco's Jazan refinery was hit; a Houthi spokesman claimed it publicly two days later and a Saudi coalition spokesman put the wounded at 73. On September 8 and 9 CENTCOM said US forces destroyed five more Iranian tankers, Iran claimed retaliatory strikes on a Jordanian base hosting American aircraft, and the Revolutionary Guard navy expanded its prohibited zone.

Brent priced that sequence at the front and almost nowhere else. Over the week the November 2026 contract gained roughly eleven dollars from Friday to Thursday while the December 2027 contract gained a dollar and a half, and on Thursday alone the front rose 6.3% against 0.8% at the back. That shape is what a supply-risk premium looks like. Barrels at risk now command more; barrels deliverable in fifteen months do not, because the risk is expected to have resolved by then. A broad demand repricing would normally reach much farther down the curve. This move remained overwhelmingly concentrated at the front, and it did the same last week.

We should disclose a change we made to our own instruments, because it touches this. We carry a demand-erosion test with a level attached to that December 2027 contract, originally $75. The contract has now closed above $75 on six consecutive sessions, which would look like a signal if the far end were moving on its own. It is not: at 0.8% against a 6.3% front, the back end is being dragged along by a war premium the test was never built to detect. We have moved the machine-read level to $85, prospectively, and the written test is unchanged and still requires a clean hold above $75 alongside a calm front, which this week emphatically did not have. Honesty about the direction of travel: this is the second time we have re-pointed that level, and a threshold re-pointed twice is one that was specified against the wrong instrument in the first place. It is not evidence that the underlying read keeps surviving.

What the week did not establish is a supply loss. Traffic through Hormuz is plainly impaired, and freight has repriced to match, with the Middle East Gulf to China tanker rate at a historic high near $760,000 a day. Nobody has yet shown a measurable new loss of barrels traceable to this week's escalation. Meanwhile the two institutions that publish forecasts split: OPEC cut demand growth for a fifth consecutive month while the EIA raised its 2026 Brent path, and the EIA's numbers closed on September 3, before the week began. Their disagreement is real and it is not yet adjudicated by anything on the tape.

The Fed path broke its freeze, and we had read the freeze wrong

For most of the week the striking fact was what the rates market refused to do. Tankers burned, Brent cleared $100, Iran claimed a strike on a base in Jordan, and our estimate of the September hike probability sat at 62.1%, session after session. We wrote that up as evidence that the prints rather than the war were the live variable for the Fed.

That reading was built on a measurement error and it does not survive. The flat line mixed a live intraday capture on one day against settlement-based prints on others. Put on a consistent settlement basis, the series held 62.1% from September 5 through September 8 and had already risen to 64.3% by Thursday, a 2.2 point move that landed on the session of the tanker strikes. The war did move the odds. It moved them a little.

Then Thursday's producer price index landed at 5.4% year on year against an upwardly revised 4.8% prior, and the estimate jumped 10.7 points in one session to 75.0%. Friday's consumer price index matched the consensus at 3.4% year on year and 0.4% on the month, with core a tenth hot, and CME's FedWatch tool put the odds near 90% afterwards. So the corrected claim is narrower than the one we published, and it is still the interesting one: two inflation prints moved the September path several times as far as a fortnight of kinetic escalation in the world's most important oil chokepoint did. That is a statement about degree. We are stating it that way because that is what the numbers carry.

It also reframes the oil story. Energy is an input to the prints that are moving the Fed. If prompt crude at $104 feeds into producer and consumer prices over the coming months, the war and the data stop being separate channels and become one channel with a lag. That is a mechanism we can watch rather than a conclusion we have reached, and the October and November releases are where it would first show up.

The metals broke, and Thursday does not say why

Silver had the better week until it did not. It settled Wednesday at $68.646, the highest in our tracking record, with the gap to our $70 line down to $1.35. On Thursday it settled $64.927, a fall of 5.4%. Gold fell $53.40 the same session to $4,407.30, a fall of 1.2%, leaving only $7.30 between the settle and the $4,400 line we watch for durability. Friday steadied both: gold $4,408.90, silver $65.19.

We would like to tell you which channel did that, and we cannot. Thursday had higher rate expectations and a firmer dollar at the same time: the dollar index closed up 0.32%, and the hike estimate rose 10.7 points. Both of those push metals the same way, so the session separates them from each other not at all. A third reading needs no macro trigger whatsoever, which is a positioning unwind after a run that had gold settling above $4,400 for five straight sessions going in. On magnitude, that third reading has something going for it. A 0.32% move in the dollar does not mechanically produce a 5.4% break in silver, and silver falling four times as far as gold in percentage terms looks more like a flush than like a clean repricing of real yields.

One thing we will not do is score this as the war leaving the metals. Haven demand can be present on a session and still be outweighed by rate and positioning pressure, and a single close cannot isolate a driver in either direction. What we can say is that other pressures outweighed whatever haven support was there. The cleaner test comes next week: whether gold holds $4,400 on settlements while hike odds stay where Friday left them.

What we're watching next

  • Salalah on Monday, September 14. Oman is trying to seat Gulf Cooperation Council foreign ministers with Iran for the first time since the war began. It is unconfirmed, the two sides describe the agenda differently, and Friday's 2.8% fall in Brent was the market taking the prospect seriously anyway.

  • The FOMC on Wednesday, September 16. Two hot-side inflation prints have taken the September path from a coin-flip conversation to something close to expected. The decision is the first thing this week that can settle rather than merely move.

  • The Bank of Japan, September 17 and 18. A hike to 1.25% is widely expected, into a Fed that is now itself expected to hike in the same week. Watch the policy gap, because compression is what the repatriation case needs and two simultaneous hikes do not deliver it.

  • Whether Brent holds triple digits on settlements. The premium arrived on a sequence of named events. The test of whether it is a regime or a spike is a quiet week.

  • Gold at $4,400. Seven consecutive settles above the line, and the last two cleared it by under ten dollars. The review level below it is $4,300.

  • The sanctions vehicle in the House, reportedly the week of September 14. The Senate passed it 86 to 11 on August 7. It has not been scheduled since.

Sources & reporting used

A note on the numbers: settlements for Brent, WTI, COMEX gold, silver and copper are taken from our data vendor's settlement-tagged board rather than from the exchanges' own settlement files, which are unreachable from our systems, so they are reported settlements and can differ by cents from an exchange print. Weekly changes in gold and silver are measured Friday settle to Friday settle on the front-month COMEX contract, so they will differ from spot quotes and from intraday reports published during Friday's session. Brent's weekly change is quoted on a single contract month, the November 2026 contract. Where a figure is given for Thursday rather than Friday, that is because Friday's print for that series was not available to us at the time of writing; the December 2027 Brent comparison is one of those. The September hike odds are our own binary, day-weighted estimate computed from the settlement price of the September fed funds contract, rather than a figure quoted from a vendor; the roughly 90% reading after Friday's inflation print is CME's FedWatch tool and is cited to CME. Our $75 and $85 December 2027 Brent levels, the $4,400 and $4,300 gold lines, the $70 silver line and the 3% Japanese ten-year line are pre-registered house thresholds applied mechanically to settlements, rather than consensus levels. Hormuz traffic figures come from different providers measuring different windows and units and are not directly comparable with each other. Ukrainian air-defense and outage counts are drawn from Ukrainian official sources.
