U.S. Crude Inventories Extend Slide to Lowest Since October 1983

Total U.S. crude oil inventories (commercial plus the Strategic Petroleum Reserve) extended their slide to 695.2 million barrels last week, the least since October 1983, per the EIA. The SPR is driving it, accounting for 125.9 million of the 136.2 million barrel drop in total inventories from a year ago.

The SPR slipped another 0.3 million barrels to 282.7 million in the week ending October 16, its lowest since 1982 and down 30.8% from a year ago. But commercial crude drew 3.1 million barrels to 412.5 million, the third straight draw (14.8 million barrels over those three weeks). That left it 3% below the five-year average and the lowest for this time of year since 2014.

Turning to products, those also remain historically low even as refiners are running hard:
▪️ Refinery utilization was 93.4%, versus 88.6% this week last year and well above the five-year range.
▪️ Gasoline fell 3.0 million barrels, the biggest draw since early May, to 205.3 million, 5% below the five-year average. Gasoline demand rose 575,000 barrels a day to 8.98 million.
▪️ Distillates rose 1.7 million barrels, the first build in five weeks, but are still 9% below the five-year average.
▪️ Products are also being drawn down by exports which are up 6.8% from a year ago on a four-week average.

One other notable: crude production fell 410,000 barrels a day to 13.27 million, the lowest since late January, as Hurricane Isaias kept Gulf of Mexico output offline (57% was still shut in as of October 12, per BSEE). Expect a rebound as platforms restart.

Mortgage Applications Drop for 7th Straight Week Despite Easing Rates

Mortgage applications fell 5.3% last week, according to the Mortgage Bankers Association (MBA), the seventh straight weekly decline, even as the 30-year fixed rate eased to 7.41% from 7.50%, its first drop in over two months. Total volume is now down 23.7% over those seven weeks.

▪️ Purchase applications fell 7% to their lowest level since early January 2025 and were 18% below a year ago.
▪️ Refinance applications fell 2% and were 59% lower than a year ago, with rates more than a full percentage point above where they were then.

MBA’s Joel Kan: “Lower rates were not enough to boost application activity, as both purchase and refinance applications continued to decline.”

CNBC’s housing reporter Diana Olick said buyers are reacting less to the weekly move in rates than to the overall higher level. The MBA’s 30-year rate has gone from 6.09% in February to 7.41% now.

U.S. Mortgage Applications Fall Again

Per the Mortgage Bankers Association, U.S. mortgage applications fell 5.3% for the week ending October 16, marking a seventh consecutive weekly decline and reaching their lowest level since January 2025.

In other words, as we can see in the chart below, the slide continues.

CyberCartel Used Claude and Grok to Attack Banks

The Information is reporting that hackers used Claude and Grok to fully automate attacks on banks, supporting our view that AI adoption and usage by bad actors would accelerate the pace of cyber attacks and be a catalyst for incremental cybersecurity spending.

Here’s the gist:

A hacking group called CyberCartel used a network of AI agents running on models from Anthropic, SpaceX (SPCX) and the Chinese lab Moonshot AI to automate cyberattacks against more than 400 Latin American financial targets, according to an investigation by the cybersecurity startup Straiker.

Data Center Blues

It’s not all positive in tech-land though as Australian data center firm Nextdc (NXT) slashed its full-year earnings guidance by a third and placed development plans on hold after protests delayed power supply to one of its major projects in Melbourne that saw the firm pause all new development work, a caution sign for other global projects that have run into opposition.

Its shares plunged almost 42% in Sydney — the most since listing in 2010 — cutting its value to about A$4 billion ($2.8 billion) while its bonds fell into distressed territory.

The delay forces the company to defer roughly A$140 million of contracted customer revenue in this financial year. Management has announced it will pause all new development projects. It has 17 in operation and 11 in development or planning.

More Bullish Tech Headlines

In addition to the well-received SpaceX (SPCX) headlines detailed last night (SpaceX Climbs as Musk Floats Tesla Merger), some other stories are boosting Tech shares this morning:

Shares of server maker Super Micro Computer (SMCI) are up over 12% premarket after the firm released preliminary quarterly numbers for the period ending September 30, saying it expects revenue of $18.5 billion to $19.5 billion for the quarter. That compares with its earlier forecast of $14.5 billion to $15.5 billion and an average analyst estimate of about $15 billion. The company also raised its gross margin forecast to 12% to 12.5%, from 10.4% to 10.8%

In addition, the Wall Street Journal is reporting that Anthropic’s draft prospectus signals coming spending on computer and power of as much as $750 billion in coming years, with $111 billion on contracts with Alphabet’s Google Cloud (GOOGL), $110 billion with Amazon Web Services (AMZN) and $31 billion with Microsoft (MSFT) “regardless of actual usage.”

Anthropic also agreed to spend up to $86 billion renting Nvidia (NVDA) chips from smaller AI cloud providers Nscale and Lambda.

And sales are growing at a blistering pace. The Journal reported revenues had grown to $16.3 billion in the six months ended June 30, up from $1.1 billion in the year-earlier period. That outpaced the nearly $9 billion on computing capacity and infrastructure, up from $2.3 billion.

Still it recorded a net loss of $80.7 billion, the vast majority ($72 billion) “tied to changes in the value of convertible notes and other instruments the company issued to raise funding.”

And finally, several Asian countries with large tech exposure (South Korea, Japan, Taiwan, etc.) are reporting strong export numbers led by semiconductor and other Tech shipments.

  • Bloomberg reports that South Korea’s exports the first 20 days of October, adjusted for working-day differences, rose 65.9% from a year earlier. While down from the 89.8% increase during the same period in September, it is otherwise a record. Semiconductors surged 222.5% from a year, while products increased 68.3%, and automobile exports almost 41%.
  • Also from Bloomberg, Japan’s September export growth rose 16.7% from a year earlier. While it missed expectations for a 21.2% increase, shipments of semiconductors and chip-making equipment surged 49.4% and 43.9% respectively (autos were +15.1%). Shipments to the US gained 22.9%. Those to China and the European Union advanced 8.6% and 10.5%, respectively.
  • Reuters reports that Taiwan’s export orders jumped 62.4% in September to a record $114.21 billion “credited to strong demand for AI, high-performance computing and cloud services applications.” The Ministry of Economic Affairs forecast October as rising between 62% and 67%. “Taiwan’s orders ​in September for telecoms products were up 87.3% from ​a ⁠year earlier, while those for electronic products jumped 71.0%.”

SpaceX (SPCX): Post-Q3 Target Raises, October 21

The SpaceX (SPCX) quarter beat on revenue and EBITDA across all three segments (Intelligence/AI, Space, Connectivity). The only blemish was a miss on Starlink subscriber adds, offset by better pricing. Guidance calls for revenue of $33B to $37B by Q1 FY27. Management says it expects 2 to 3 GW of compute by year-end 2026 and plans to add 10 GW in 2027, well above prior expectations, and told JPMorgan it is not considering raising equity.

Price targets:

  • JPMorgan: $500 from $240 (Overweight). Biggest move. Says the forward driver is superintelligence, not the segment beats.
  • Cantor Fitzgerald: $345 from $246 (Overweight). Sees $500B to $1T in year-end 2027 ARR, self-funded compute expansion, and chip supply constraints giving SpaceX pricing power.
  • Barclays: $300 from $254 (Overweight). Model update on the beat.
  • Morgan Stanley: $300 reiterated (Overweight). Says the story is only now getting interesting.
  • Citi: $240 from $200 (Buy). Also opened a 90-day upside catalyst watch, pointing to Q4 beat-and-raise continuation and Starship Flight 15 as a major reusability catalyst.
  • UBS: $230 from $210 (Buy). New compute deals ramping in Q4, Starship catch milestones, Grok improvements.
  • TD Cowen: $224 from $200 (Buy). Estimates up on the beat.
  • Susquehanna: $176 from $173 (Neutral). The lone holdout. Flags execution risk on the compute buildout and dependence on Starship commercialization.
