Fed, BoJ and Oil: A Decisive Week

The week begins with an unusually unstable combination: still-elevated U.S. inflation, sharply weaker consumer sentiment, oil above $108 per barrel and two major monetary-policy meetings taking place within days of each other.

Markets must now determine whether the global economy is undergoing an orderly slowdown or whether the energy shock could trigger a new period of stagflation. Demand is losing momentum, but producer prices and inflation expectations remain too high for central banks to ease monetary policy quickly.

Recent data: weaker consumers, persistent price pressures

The most significant release last week was the U.S. August CPI. Headline inflation rose 0.4% month over month, leaving the annual rate unchanged at 3.4%. Core CPI increased 0.3% on a monthly basis and 2.4% year over year.

Energy was the main source of pressure: gasoline prices rose 3.9% during the month, while the energy index increased 2.1% month over month and 16.3% year over year. Headline inflation was in line with expectations, but the monthly increase in core prices was stronger than the more optimistic forecasts. 

The producer-price data were even more concerning. The U.S. PPI rose 0.4% in August and 5.4% year over year. Goods prices increased 1.1%, compared with just 0.1% for services. The acceleration is therefore concentrated in material, energy and logistics costs, but it could be passed on to final prices and corporate margins in the coming months. 

The consumer picture is less reassuring. The preliminary University of Michigan consumer-sentiment index fell to 47.8 from 51.7 in August, well below expectations. The expectations component dropped to 45.8 from 51.5. One-year inflation expectations jumped to 4.6% from 4.0%, while five-year expectations rose to 3.4% from 3.3%. 

The message is clear: households are experiencing a deterioration in their financial outlook and fear that fuel, food and transportation costs will continue to erode purchasing power.

The housing market also confirms the economy’s sensitivity to interest rates. Existing-home sales fell 2% in August, to an annualized pace of 3.98 million units, while 30-year mortgage rates approached 6.8%. Prices, however, remain high because of limited supply. This is typical of a market constrained by borrowing costs, rather than a systemic housing crisis.

The labor market remains comparatively resilient. Weekly jobless claims are still low at 206,000, the unemployment rate stands at 4.1% and August payrolls increased by 162,000. Employment resilience reduces the risk of an immediate recession, but it also makes it harder for the Federal Reserve to justify a rapid easing cycle.

The new geopolitical oil shock

Geopolitics has once again become the main inflation risk.

Overnight from Sunday into Monday, new attacks attributed to Iran-aligned Houthi forces reportedly led to the temporary closure of Saudi Arabia’s East-West pipeline, an infrastructure link that transports crude toward the Red Sea while bypassing the Strait of Hormuz.

Its unavailability threatens to remove up to 4% of global supply from the market. The port of Yanbu reportedly has enough inventory for only five to seven days of exports, according to industrial sources cited by Reuters. At the same time, a vessel was struck in the Strait of Hormuz, while talks between Iran and Gulf countries on a temporary maritime route were postponed. Reuters

At 09:24 GMT on Monday, Brent crude was up 3.3% at $108.04, while WTI gained 3.5% to $103.54. Brent had already risen approximately 9% the previous week, and U.S. diesel prices exceeded $6 per gallon for the first time.

The economic impact is not limited to gasoline. More expensive crude and diesel raise transportation, manufacturing, agricultural, aviation and distribution costs. If the crisis persists, the shock could spread to food and service prices, making core inflation more persistent.

Today’s market reaction

Today’s session is marked by pronounced risk aversion.

The KOSPI has been hit hardest because of its heavy concentration in semiconductors and technology. SK Hynix fell more than 6% and Samsung Electronics around 4%. The Nikkei was pressured by weakness in SoftBank, chipmakers and expectations of a BoJ rate increase. 

Ahead of the Wall Street open, Nasdaq 100 futures were down 1.7% and S&P 500 futures 0.7%. Pressure on technology stocks is not driven solely by oil and interest rates: over the weekend, several industry leaders, including the heads of Anthropic, OpenAI and xAI, called for greater caution in developing artificial-intelligence systems.

Investors fear that regulatory or technological delays could postpone investment in data centers, semiconductors and digital infrastructure, just as valuations reflect very high growth expectations. 

Today’s move is therefore the result of three simultaneous shocks:

1. higher oil prices and renewed inflation risk;

2. rising expectations of further monetary tightening;

3. profit-taking in AI stocks after months of strong gains.

Federal Reserve: markets price in a 25-basis-point hike

The Federal Reserve will meet on September 15–16. The decision will be released on Wednesday, September 16, at 2:00 p.m. New York time, or 8:00 p.m. in Italy, together with updated economic and interest-rate projections. 

Money markets now assign roughly a 90% probability to a 25-basis-point rate increase, which would take the federal-funds target range to 3.75–4.00%. One week ago, the probability was close to 60%.

The Fed faces conflicting signals:

• CPI, PPI and inflation expectations call for restrictive policy;

• consumer sentiment, housing and investment point to a slowdown.

The rate increase therefore appears largely priced in. The greater market risk lies in the communication from Chair Kevin Warsh. If the Fed presents the move as an isolated response to the energy shock, Treasury yields could stabilize. If it signals further tightening, the 10-year yield could move above already-high levels and compress equity-market multiples further.

BoJ: normalization and carry-trade risk

The Bank of Japan will meet on September 17–18, with its decision expected on Friday, September 18. The bank kept its policy rate around 1% at its July meeting, but markets now regard a 25-basis-point increase to 1.25% as highly likely. 

The case for tightening is supported by Japanese producer inflation, higher import costs and yen weakness. The possibility of further increases in 2027 has already supported the currency and reduced speculative positions financed in yen.

A larger-than-expected increase or particularly hawkish guidance could trigger another unwinding of the carry trade, leading to selling in technology, emerging markets and highly leveraged assets.

ECB and Bank of England: spillover effects

The ECB already raised rates by 25 basis points on September 10: the deposit rate to 2.50%, the main refinancing rate to 2.65% and the marginal lending facility rate to 2.90%, effective September 16.

Updated projections point to average inflation of 3% in 2026 and 2.5% in 2027. Governing Council member Martins Kazaks said on Monday that 2.50% should not be considered a ceiling and that the case for further tightening is strengthening if higher energy costs pass through to wages and prices. 

The Bank of England will also meet on September 17. The prevailing consensus is for the policy rate to remain at 3.75%, but markets are increasing the probability of a rate hike by November because of oil prices and renewed inflation expectations. 

This week’s macroeconomic calendar

The dates of the main U.S. releases are confirmed by the Census Bureau and Bureau of Labor Statistics calendars. 

How to interpret the week

The most favorable scenario for risk assets would be a 25-basis-point Fed hike accompanied by guidance that the move is linked to the energy shock and does not mark the beginning of a prolonged tightening cycle. In that case, yields could stabilize, the dollar could give back some of its gains and quality stocks could recover.

The most negative scenario would combine oil at $110–120 or above, rising inflation expectations and a Fed prepared to tighten further. That would increase the risk of stagflation, putting simultaneous pressure on equities and bonds.

In equity markets, energy and defense remain relatively favored by the current geopolitical environment. Healthcare, consumer staples, utilities and quality companies could offer greater resilience during a slowdown. Technology and semiconductors are more exposed to higher real yields and a reassessment of AI-investment expectations.

Conclusion

The week will not be determined solely by the size of the Fed and BoJ decisions, but also by their ability to interpret a shock that central banks can influence only indirectly.

The U.S. CPI confirmed that inflation has not yet been defeated; the Michigan survey showed that households are already adjusting their expectations; oil is adding a new impulse to prices; and equity markets are selling the most highly valued and rate-sensitive sectors.

For now, there is not enough evidence to describe an imminent recession. There are, however, increasingly numerous signs of a slowdown in an environment where inflation may remain too high to permit a rapid reversal of monetary policy. Oil prices, Treasury-market behavior and the language used by the Fed and BoJ will therefore be the three most important indicators to monitor in the coming days.
