Opec+ is on track to approve another output increase of around 188,000 barrels a day for September at its meeting on August 2, sticking to the same incremental schedule it has followed for months. But with a fresh flare up in the Red Sea alongside the ongoing Strait of Hormuz disruption, much of that additional supply looks unlikely to actually reach buyers, leaving the quota rise largely symbolic.The military backdrop remains the dominant driver. US Central Command confirmed American forces carried out a 13th consecutive night of strikes against Iranian military targets, part of a campaign aimed at holding Iran accountable and reducing threats posed by the Revolutionary Guard to commercial shipping. Diplomacy showed little traction in parallel: Iran rejected a ceasefire proposal from President Trump that was delivered to Tehran by Iraq's prime minister, with Iranian officials warning that any US strike on Tehran itself would prompt Iran to widen the war, including retaliatory strikes on Tel Aviv and a push for its Houthi allies to close Bab al-Mandeb.On trade, the Trump administration confirmed it will impose new tariffs of 10 to 12.5 percent on 60 trading partners from Friday, replacing an expiring temporary levy with duties built on a more legally durable footing following the Supreme Court's earlier rejection of its global tariff program.Currency markets stayed focused on Japan. The US Treasury's latest report pressed the Bank of Japan to continue raising rates as the yen touched a 40 year low, warning that excessive currency volatility is undesirable. Japan's finance minister Katayama followed up by confirming Tokyo and Washington remain in close, round the clock contact, and reiterated that Japan stands ready to take decisive action on the currency if needed. June inflation data offered little fresh direction for the pair, with headline and core CPI both landing in line with expectations, though the core-core measure slowed to its softest pace since August 2022, giving the BOJ some room to stay patient at next week's meeting. USD/JPY traded steadily around 163.80, with only a slight touch of broader dollar softness evident elsewhere across major currencies.Asian equities bore the brunt of the day's risk aversion, driven by a mix of oil and AI related concerns. South Korea's KOSPI fall was severe enough to trigger sidecar trading curbs, with a similar halt activated on the KOSDAQ after futures there dropped more than 6 percent. Japan's Nikkei fell around 2.5 percent in sympathy. In a move aimed at containing market volatility, South Korea's financial regulator brought forward the start date for a higher deposit requirement on retail trading of single stock leveraged ETFs to July 31, requiring a cash deposit of roughly 30 million won, about 20,000 US dollars. The measure targets speculative trading in leveraged products tied to Samsung Electronics and SK Hynix, which were approved in late May and have since drawn criticism for amplifying volatility in the broader market.
