The recurring tensions between the US and Iran trigger volatility in Japanese bonds, putting pressure on ultra-long maturities and steepening the yield curve.
- Japanese government bond futures opened lower on Monday, dropping 27 ticks from last Friday to 127.48 and further declining in early trading to an intraday low of 127.46. The main drag came from risk-off sentiment triggered by uncertainty over US-Iran peace talks.
- As US Vice President Vance and Iranian officials held their first meeting and negotiations made progress, market panic eased somewhat. Buy orders emerged at lower levels, pushing the short end, as well as five-year and ten-year yields, down from their morning highs, though selling pressure on the ultra-long end remained obvious.
- The yield curve displayed steepening characteristics, with the ten-year yield rising 3 basis points to 2.675%, and the thirty-year yield briefly climbing 4 basis points to 3.875%. Some 1940s and thirty-year bond varieties faced selling pressure due to demand for curve inversion correction.
- In terms of capital flows, domestic regional banks and life insurers acted as buyers at the short end, with some funds likely coming from reinvestment demand after a large volume of government bonds matured two days earlier. In the afternoon, regional accounts, pension accounts, and offshore accounts became sellers at the short to medium end, highlighting clear divergences between bulls and bears in the market.

Updated: 2-ArriVent’s oral lung cancer therapy fails in late-stage clinical trial, shares plunge
In the first paragraph, stock information was added. Paragraphs 2 to 8 provide a detailed introduction to the disease and the clinical trial situation. Reuters, Oct. 6 - ArriVent BioPharma (AVBP.O) said on Tuesday that its oral therapy for treating rare lung cancer failed to meet its primary goal of delaying disease progression in a late-stage clinical trial, leading to its shares plunging by 63% in premarket trading. The therapy, firmonertinib, targets previously untreated advanced non-small cell lung cancer (NSCLC) patients who carry a gene mutation called the EGFR exon 20 insertion, which can promote cancer growth. This mutation accounts for about 0.5% to 1% of all NSCLC cases. NSCLC represents about 85% of all lung cancer cases. In the trial, according to independent reviewers, the 240mg dosage developed by ArriVent extended median progression-free survival to 11 months, compared to 9.5 months in the chemotherapy group. Chief Executive Officer Bing Yao stated that the improvement in progression-free survival (defined as the length of time patients live without worsening or spread of disease) was not significant. "These disappointing results are not what we had hoped for, especially for patients with EGFR exon 20 insertion-mutant NSCLC who are in urgent need of more effective treatments," said Yao. The company is evaluating the full data set to determine the most suitable development path for firmonertinib. ArriVent stated that no new safety signals were observed in the trial. The therapy has already been approved in China for non-small cell lung cancer patients carrying specific mutations.
