Financial News Roundup: Treasury Yields and Middle East Risks Intertwine; Brazil Election, US Equity Short-Squeeze Signals in Focus

Drawing on recent reports and institutional views, market attention is focused on US Treasury yields, Middle East geopolitical risks, Brazil's election, and fourth-quarter positioning changes in US equities.

**Bond Market and Fed Signals** US Treasury Secretary Bessent recently defended the recent rise in government bond yields, saying the 10-year Treasury yield touched its highest level since 2002 at one point this week, but this rate move is a global phenomenon and does not warrant excessive concern, with no sign of markets selling Treasuries and switching to German or Japanese government bonds ^[2]. He also rejected AI bubble concerns, arguing that large capital investments by leading tech companies such as Microsoft, Google and Meta, and the substantial revenue growth they have generated for companies such as Anthropic and OpenAI, are fundamentally different from a bubble with no fundamental support ^[2].

A heavyweight financial calendar covering the week of October 5 to October 11 shows that the Fed's September meeting minutes will be published on October 8, with Bloomberg expecting “almost everyone” to support at least one more rate hike this year; internal divisions and Warsh's proposal to cut regular meetings are also in focus ^[1]. In the same week, $39 billion of 10-year and $22 billion of 30-year Treasuries will be auctioned in a concentrated schedule, and Bank of Japan Governor Kazuo Ueda will deliver a keynote speech on Monday ^[1]. In addition, China's end-September foreign exchange reserve data will be released on October 7, after the end-August balance stood at $3,438.33 billion; in August, China's central bank had increased its gold holdings for 22 consecutive months; the US September ISM non-manufacturing index will be released on October 5, with the previous reading at 55.4 and the median economist forecast at 55.0 ^[1].

BofA Securities chief investment strategist Michael Hartnett warned in the latest Flow Show report that the current market structure closely resembles the eve of the bursting of the 2000 dot-com bubble; 400 S&P 500 constituents have fallen below their 50-day moving averages and 300 below their 200-day moving averages, with market gains highly concentrated in AI-related sectors represented by the “Mag7” ^[5]. He noted that the 10-year Treasury yield has risen to 5.33%, a new high since 2002, and advised clients to start adding to bond positions, saying long-term Treasury returns have fallen to their lowest level in a century ^[5].

**Geopolitics and Energy Standoff** In the Middle East, the Houthis said in a statement late on October 3 local time that, in response to Saudi airstrikes on Sanaa and other parts of Yemen, they used multiple ballistic missiles and drones that day to strike Aramco targets in the Saudi capital Riyadh, saying the operation “successfully achieved its objectives” and “hit the targets and caused fires” ^[3]. Saudi Arabia has not yet issued an official statement on the attack; unverified footage circulating on social media platform X showed thick black smoke rising from multiple locations at the Aramco refinery in Riyadh ^[3]. According to Turkish media Türkiye Today, citing data from NASA's FIRMS satellite monitoring system, high-intensity thermal radiation signals appeared in the refinery area; the Riyadh refinery has a daily processing capacity of about 130,000 barrels ^[3].

According to Axios, citing two US officials, Saudi Arabia is planning to launch a large-scale military operation against the Houthis in the coming days, targeting the coastal areas that have allowed the Houthis to control the Bab el-Mandeb Strait, a key maritime chokepoint; US officials said the United States “will not take kinetic military action for now” ^[3]. Meanwhile, on October 2 local time, G7 leaders said in a statement that the G7 will coordinate through the International Energy Agency to release 100 million barrels of strategic oil reserves, with the action to begin “immediately” and last four months, starting with a large-scale release of diesel reserves in the first 20 days ^[1].

**Brazil Election and US Equity Positioning** Brazil's first-round presidential election vote opened on Sunday, with 160 million voters set to decide the contest between incumbent President Lula and right-wing challenger Flávio Bolsonaro ^[4]. A Datafolha poll released on Saturday showed that, on a valid-vote basis, Lula narrowly led 45% to 42%; Quaest's data were closer, at 46% to 45%, both within the margin of error ^[4]. The market broadly expects the first round to fail to produce an outright majority, with the race likely heading to an October 25 runoff; prediction markets currently give Flávio about a 60% chance of winning ^[4]. The Brazilian real's one-week implied volatility has surged above 31%, the highest level since late 2022 ^[4].

In US equities, aggregate CTA (trend-following quantitative fund) positioning plunged from extremely overweight at end-August to slightly net short, a swing of more than 3 standard deviations within one month; strategist Rubner's research showed the CTA positioning Z-score fell from +2.35 at end-August to -0.80 ^[6]. US companies have authorized a record $1.3 trillion in buybacks this year, and execution windows will reopen progressively from October 15; Rubner data show that since 1930, the S&P 500 has risen an average of 5.6% in the fourth quarter of midterm election years, nearly double the 2.9% average for the fourth quarter across all years ^[6]. According to Goldman Sachs, hyperscaler bond issuance is expected to reach $420 billion by 2027, but interest expense remains a small share of their earnings; according to Morgan Stanley, these companies' net leverage is only 0.4x, and cash equals 132% of debt ^[6]. According to Goldman Sachs, although global crude inventories are above minimum operating levels, the buffer has become significantly thinner, and $100 oil is not inconsistent with the current supply-demand balance; the crude oil volatility index (OVX) is currently flat with levels seen when oil was below $80, suggesting tail risk may be underpriced ^[6].
