Japan's Nikkei 225 fell as much as 3 percent and Australia's three-year government yield jumped 20 basis points to 5.05 percent, a multi-year high, after Brent crude approached $110 a barrel and US producer prices rose at their fastest monthly pace since May.
"The combination of resilient US employment and renewed pressure from energy prices are both hawkish signals," said Fawad Razaqzada, market analyst at FOREX.com. "A sustained rise in oil prices would risk reversing the progress on inflation that policymakers have been relying on to justify lower interest rates, while simultaneously squeezing consumers and businesses."
The MSCI Asia-Pacific index dropped 1.3 percent, with South Korea's Kospi down 2.7 percent. Samsung Electronics fell 3.8 percent and SK Hynix 4 percent, the two chipmakers bearing the brunt of a rate-sensitive selloff in Seoul. West Texas Intermediate rose 0.6 percent to $103.05 a barrel, its highest settlement since May 19, while Brent traded near $110 during US hours.
The regional move tracked a fourth consecutive down session on Wall Street, where the Dow Jones Industrial Average lost more than 300 points and the S&P 500 and Nasdaq Composite each fell about 0.6 percent to 0.7 percent. All attention now sits on Friday's US August consumer price index, the last major input before the Federal Reserve's September 16 decision.
Rate-swap markets priced the probability of a Fed hike next week at about 70 percent and fully absorbed an October increase after the August PPI print. The producer price index rose 0.4 percent month on month and 5.4 percent year on year, the largest monthly gain since May.
"US PPI came in hot, and combined with Lagarde's hawkish remarks, both point to one reality — a new global central bank hiking cycle may already be under way, which is not supportive of risk assets now or in the near term," said Joe Brusuelas, chief economist at RSM US LLP.
European Central Bank President Christine Lagarde added to the tightening case, saying euro-area inflation risks extend to 2027. The ECB is expected to raise rates on Thursday.
Australia's three-year yield hits a multi-year high
The bond leg of the selloff was sharper than the equity leg. Australia's 10-year yield climbed 12 basis points to 5.37 percent, Japan's 10-year rose 5.8 basis points to 2.981 percent and its 20-year added 5.5 basis points to 3.805 percent, while New Zealand's two-year yield rose 21 basis points.
The trigger came from Washington, where the US 10-year Treasury yield touched 4.97 percent, the highest since October 2023. Traders pointed to three catalysts: the hot PPI reading, the Treasury's first expanded buyback of 10- to 20-year notes under Secretary Scott Bessent, which repurchased less than investors expected, and the oil move itself.
"Yields and oil prices may both need to come down before equities can stabilize," said Stephanie Roth, chief economist at Wolfe Research. She said a CPI print "clearly below expectations" on Friday could give the market room to breathe.
The energy shock has a specific origin. The US-Iran conflict is now in its seventh month, and attacks on shipping in the Strait of Hormuz have multiplied. Iran said it struck a US military base in Jordan after American attacks on its vessels in the waterway, and warned it would target tankers off Kuwait and Bahrain. Before the war, the strait carried roughly a fifth of global oil and gas supplies.
"The broadening of the conflict threatens to risk even deeper disruption to oil supplies that had already left the oil market scrambling to adjust," said Daniel Hynes, an analyst at ANZ, in a client note. The US Energy Information Administration raised its oil price forecasts for this year and next on Wednesday as global stockpiles fell.
CPI is the binary for September 16
Economists surveyed by Dow Jones expect August CPI to rise 0.4 percent month on month and 3.4 percent year on year. A print in line with consensus would be the fourth consecutive encouraging inflation reading and would ease pressure on the Fed to move next week.
"If the data comes in as expected, it would be the fourth consecutive encouraging inflation reading and could relieve pressure on the Fed to hike in September," said Christopher Hodge, chief US economist at Natixis CIB Americas. "If inflation comes in above expectations, we expect the Fed to announce a hike at next week's meeting."
The stakes are visible in the cost of capital. Refinance rates have climbed to 7 percent, and gasoline has held near $4.15 a gallon, both of which feed directly back into the same consumer price index the Fed is watching. ING commodities strategist Warren Patterson said the oil rally "will be a major concern ahead of the midterm elections," adding that a further leg higher would require the recent escalation to actually interrupt flows through Hormuz.
For Asian portfolios, the arithmetic is unforgiving: every 10 basis points added to Australian three-year yields raises the discount rate applied to the region's long-duration technology names, which is why Samsung and SK Hynix fell harder than their respective benchmarks. A CPI surprise to the downside on Friday would reverse that math quickly. A surprise to the upside would put a September hike in play and extend the duration selloff into the following week.
