美国至8月18日6周国债竞拍-得标利率配置百分比 37.04%，前值2.86%。

US housing starts slowed in July, falling 12.4% to a 1.24 mln annualized pace versus a 1.35 mln survey expectation. Single-family starts dropped 9.9% to 808k, the lowest since November 2022. Multifamily starts fell nearly 17% after a prior surge. The pullback highlights difficulty for the US housing market to regain momentum amid rising mortgage rates since the Iran war outbreak and elevated home prices. Residential investment made a small positive contribution to Q2 GDP — the first in 2024 — but gains were modest. Outlook for starts remains unclear.

Sichuan provincial government office issued implementation opinions to accelerate integration of corridor, logistics and data networks and to orderly expand unmanned logistics across urban-rural delivery, trunk transport, park short‑haul, warehousing/sorting and loading operations.

It prioritises supply chains for lithium batteries, PV modules and new‑energy vehicles and calls for government‑market collaboration to build carbon emissions accounting and carbon‑footprint management systems, guiding firms to establish carbon‑asset management and participate in carbon trading to drive green transformation across production, distribution and consumption.
