Global Mood: Cautiously Risk-off
Drivers: US Vows Toughest Iran Sanctions, US Treasury climb back

Asian markets turned risk-off Friday as renewed selling in long-dated government bonds pushed yields higher and weighed on equity valuations. Japan’s Nikkei fell 0.92%, South Korea’s Kospi declined 1.07% and Australia’s ASX 200 slipped 0.21%, while the Kosdaq dropped 2.44%. The bond selloff reflected persistent inflation concerns and rising government borrowing costs, keeping global financial conditions tight. 

Geopolitical risks added to the pressure. The US signalled tougher sanctions on Iran, raising the prospect of a wider economic confrontation with China, its largest buyer of Iranian oil. Washington also imposed fresh sanctions linked to Hezbollah. Meanwhile, Russia’s latest missile and drone barrage on Kyiv, which killed at least 17 people, reinforced concerns over intensifying geopolitical instability. Markets are therefore balancing elevated yields and tighter financing conditions against the potential economic fallout from sanctions and prolonged conflicts. The immediate mood remains defensive, with bond-market volatility and geopolitical risks limiting appetite for equities.

THE BIG STORY
Treasury Secretary Bessent pledged "the toughest sanctions in history" on Iran Thursday, framing the economic campaign as an alternative to resumed large-scale military strikes and promising details at a Monday press conference. Trump had a day earlier threatened "economic warfare" against any country providing Iran a lifeline, a barely veiled warning to China, which buys over 80% of Iran's shipped oil. Bessent said a successful sanctions campaign would collapse the Iranian regime, while China's embassy responded that "sanctions and pressure do not help resolve the problem," setting up a potential secondary sanctions confrontation with Beijing that could have significant implications for US-China trade relations at a time when rare-earth mineral flows remain a point of leverage. The US simultaneously imposed fresh sanctions on Hezbollah, redesignating it as an agent of Iran's IRGC Quds Force and targeting a Turkish businessman running cash smuggling networks across the region.

Russia launched one of the most devastating attacks of the war on Kyiv Thursday night, killing 17 people and injuring over 40 in a massive wave of cruise, ballistic and hypersonic missiles alongside 168 drones. A nine-storey residential block was destroyed, with a school, children's hospital and kindergarten among the 30 buildings damaged across the capital and surrounding region. Zelenskiy declared Friday a day of mourning and called the strike one of the most "cynical and calculated" of the entire war, again pleading with allies for Patriot interceptors as Ukraine's stocks run critically low. The air force downed nearly 90% of drones and most cruise missiles but did not confirm any ballistic missile intercepts, underscoring the asymmetric vulnerability that is now costing Ukrainian civilian lives at an accelerating rate.

Data Spotlight
Initial jobless claims fell 6,000 to 206,000 in the second week of August, below expectations of 210,000 and maintaining the streak of low claim counts since July's near 60-year low. Continuing claims rose 18,000 to 1,799,000, though the data overall continued to point to labour market resilience despite July's unexpected payroll contraction.

The Philadelphia Fed Manufacturing Index surged to 47.4 in August from 41.4 in July, its highest since April 2021 and far above expectations of 25, with nearly 57% of firms reporting higher activity. Employment jumped to its strongest reading since April 2022, while price pressures moderated. The future general activity index surged 39 points to 73.6, its strongest reading since August 1983.

Japan's annual inflation rose to 1.9% in July, a seven-month high, as government energy subsidy reductions slowed the decline in electricity prices and food, transport and household goods costs accelerated. Core inflation, excluding fresh food, rose to 1.8%, matching expectations but remaining below the Bank of Japan's 2% target for a sixth consecutive month.

Takeaway: Philadelphia manufacturing's surge to multi-year highs and resilient jobless claims contrast with July's weak payroll print, pointing to an uneven US economic picture. Japan's rising inflation, driven partly by subsidy withdrawal, adds pressure on the Bank of Japan to reassess its policy stance as price pressures broaden.

  • Treasury yields resumed their climb despite Wednesday's buyback announcement, with Bessent flagging possible further buyback increases, though yields quickly reversed their brief pullback.

  • FOMC minutes confirmed some policymakers favoured raising rates this year to prevent stronger inflationary pressures from emerging later, keeping tightening risk alive despite the dollar's weakness.
