Hawkish Fed Outlook and Persian Gulf Tensions Drive Markets Lower
Global markets started the week under pressure as Federal Reserve Chair Kevin Warsh’s hawkish comments pushed investors to sharply increase expectations for a near-term interest-rate hike, while renewed tensions in the Persian Gulf drove oil prices higher. Equities and gold extended their declines as investors reassessed the outlook for monetary policy and geopolitical risk.
MSCI’s Asia Pacific equity gauge fell 0.7%, with South Korea’s Kospi declining 1.2% as Samsung Electronics and SK Hynix weighed on the index. European equity futures pointed to further declines, while Nasdaq 100 futures remained under pressure following last week’s semiconductor selloff.
Gold fell to around $4,415 an ounce as expectations for higher interest rates reduced demand for the non-yielding asset. Brent crude, meanwhile, climbed 2.5% to approximately $90.25 a barrel as renewed military activity in the Persian Gulf increased concerns over energy and shipping flows. Bitcoin also weakened, trading around $77,500.
US Treasuries recovered part of Friday’s losses, with the two-year yield falling 2 basis points to 4.32%. The Dollar also eased after recording its strongest one-day gain in two months following Warsh’s Jackson Hole speech.
Markets now see around a 60% probability of a Federal Reserve rate hike next month, compared with approximately 34% before Warsh’s comments. Investors are also pricing in at least one additional increase over the following year, marking a significant shift in the interest-rate outlook.
Warsh said financial conditions were not currently restrictive and described interest rates as the Fed’s “predominant tool” for achieving its mandate. While he stopped short of explicitly supporting a September rate increase, his comments were interpreted as sufficiently hawkish to reinforce expectations for tighter monetary policy.
The Yen strengthened to around 159.77 per Dollar, although traders remained alert to further intervention rhetoric from Japanese officials following the currency’s sharp decline on Friday. US Treasury Secretary Scott Bessent also said he expects Bank of Japan Governor Kazuo Ueda “to do the right thing” on monetary policy, keeping Japan’s rate outlook firmly in focus.
The biggest market risk, however, was renewed escalation across the Persian Gulf. US forces struck Iranian rocket launchers on Sunday in the first reported American military action against Iran in more than a month. The US said the launchers were preparing to send mines into the Strait of Hormuz, highlighting the potential threat to one of the world’s most important energy corridors.
Iranian authorities subsequently issued a series of statements indicating that tensions around the Persian Gulf and Strait of Hormuz remain elevated. Iran’s Revolutionary Guards said vessels must comply with Iranian rules for transit through the Strait and claimed that a tanker had attempted to cross the southern Strait of Hormuz illegally. Iranian state media also reported that a supertanker caught fire and stopped after hitting two naval mines in the Strait.
Iran further warned that the US and its allies would bear responsibility for the consequences of any escalation and said it would respond decisively to further hostile military action. Iranian authorities also claimed that its armed forces had targeted US military bases in Jordan in retaliation for a US strike on Larak Island, while the Revolutionary Guards said a US MQ-9 drone had been shot down over the Strait of Hormuz.
The UAE also reported heightened tensions across the Persian Gulf. The UAE Foreign Ministry condemned what it described as an Iranian drone attack and said its air defenses intercepted a drone over UAE territorial waters. Abu Dhabi stated that it reserved the full right to respond, while Iranian authorities claimed that a drone strike had targeted the UAE’s Al Minhad air base.
The escalation has direct implications for global energy markets. Brent crude rose as renewed fighting in the Persian Gulf highlighted the risks to oil flows through the Strait of Hormuz. Any prolonged disruption to shipping through the waterway could introduce a significant risk premium into crude prices and potentially create renewed inflationary pressure for economies already dealing with elevated price levels.
Iran’s National Oil Company also said oil operations at Kharg Island had not stopped, according to Nour News. Kharg Island is a critical component of Iran’s oil-export infrastructure, making developments around the facility particularly relevant for global energy markets.
Elsewhere, China’s factory activity improved in August but remained in contraction territory, providing some evidence of stabilization while highlighting continued challenges for the world’s second-largest economy. Policymakers remain under pressure to introduce additional measures to support domestic growth.
Overall, markets entered the new week facing a difficult combination of higher interest-rate expectations and renewed Persian Gulf geopolitical risk. The prospect of tighter US monetary policy is weighing on equities and gold, while renewed tensions around the Strait of Hormuz are supporting oil prices and increasing the risk of another inflationary shock. Investors will closely monitor developments from the Federal Reserve, Japan and the Persian Gulf as markets assess whether the current rise in geopolitical risk becomes a sustained driver of global asset prices.
