Fed's Warsh Opens Door to Rate Hike as Oil Slides and AI Stocks Rally

What Warsh's Jackson Hole Shift Signals for Rates and Markets

By the time of publication, Federal Reserve Chair Kevin Warsh had already delivered the Jackson Hole remarks that markets were waiting for. The message was hawkish in tone but conditional in substance. He offered no promise of a hike, yet he said the Fed needs to be confident that core inflation is moving toward 2% 'clearly and fast enough'; otherwise the central bank 'has work' to do. The shift came as core PCE inflation printed above forecasts and FedWatch pricing put the probability of a December rate increase above 70%, keeping Treasury yields elevated.

Oil markets eased after Brent slipped to $88 a barrel on signs of progress over the Strait of Hormuz. Iran said it had reached a revenue-sharing agreement with Oman covering the strategic waterway, though Tehran cautioned that the deal does not guarantee an immediate reopening. Supply risks remain elevated because Ukrainian drone strikes continue to hit Russian refineries and ports. The mixed supply picture knocked US-listed oil majors: ExxonMobil fell 5.3%, ConocoPhillips 4.0%, Occidental Petroleum 3.5% and Chevron 2.7% within the KASE Global universe.

Equity markets split between rate-sensitive legacy names and AI-led growth. Nike dropped 5.7%, Coca-Cola 2.2% and Johnson & Johnson 1.7% on the difficult macro backdrop. In contrast, Nvidia rose 7% after reporting strong demand for AI computing capacity and forecasting about 70% revenue growth next financial year. That outlook lifted Micron by 3%, AMD by 1%, Microsoft by 4.5%, Oracle by 3.7% and Salesforce by 20.5%. Expectations of large AI-infrastructure IPOs, including Anthropic and OpenAI, added further support. Meta gained 3.9% after agreeing to a $16.7 billion settlement with US states over its teen-focused social media strategy.

The Kazakhstan benchmark KASE rose 1.4% to 8,131.71, with six of ten index stocks gaining. Kazatomprom led with a 9.5% advance after an international rating agency affirmed its BBB rating with a stable outlook. KazTransOil added 3.7% after first-half 2026 revenue rose 10.3% to 179.9 billion tenge and net profit grew 33.4% to 29.4 billion tenge. Financials were mixed: Kaspi.kz gained 3.2%, Bank CenterCredit edged up 0.04%, while Halyk Bank fell 3.4% as the shareholder register closed for dividend entitlement. Air Astana slipped 1.8% despite disclosing a small GDR buyback.

Inside the Market Split: Oil Diplomacy, AI Strength and Fed Policy

Warsh's Shift Is About Core Inflation, Not a Promise to Hike

The most important signal is the conditional nature of Warsh's language. He did not commit to raising rates, but he lowered the bar for the Fed to act if core PCE does not move convincingly toward 2%. That is why FedWatch odds above 70% are now a meaningful market input. The Treasury's expanded buyback discussion adds a second layer: if the Treasury uses almost $1 trillion from its General Account to finance bond buybacks rather than issue new debt, the supply dynamics in the Treasury market could offset some of the pressure coming from the Fed's inflation fight.

Oil's Dip Is Diplomacy, Not a Supply Fix

The Iran-Oman agreement explains Brent's retreat to $88, but it is a revenue-sharing arrangement, not a reopening guarantee. Iran's own caution keeps conflict risk alive. Ukrainian drone strikes on Russian refining and port infrastructure are the other unresolved supply threat. That is why integrated producers and shale names fell even as headline crude eased: the market is discounting a diplomatic headline but still repricing physical delivery risk.

AI Infrastructure Is Again the Engine of Market Strength

Nvidia's 70% revenue-growth forecast pushes back against the narrative that AI capital expenditure is about to slow. The wider move in Microsoft, Oracle, Salesforce, Micron and AMD shows the rally is not confined to one chipmaker. Expected IPOs from Anthropic and OpenAI add an issuance halo, but this is still expectation rather than completed supply. A further leg in AI-linked valuations will depend on whether those demand signals survive the next earnings cycle.

KASE's Local Story Is Company-Specific, Not a Broad Risk-On Move

The 1.4% weekly gain in the KASE index was driven by Kazatomprom's rating affirmation and KazTransOil's profit growth, not by a uniform rally in Kazakh equities. Halyk Bank's decline looks technical, tied to the dividend record date, while Air Astana's buyback is relatively small. This matters for KASE Global investors because it separates earnings and rating catalysts from index-level momentum.

What Investors Should Take From Oil, AI and KASE Signals

For investors and professionals tracking US rates, oil, AI names and Kazakhstan-listed equities, the following signals follow directly from this week's developments.

• US rate expectations: The FedWatch probability of a December hike has moved above 70%, but Warsh tied any move to core PCE reaching 2% 'clearly and fast enough.' Use the next core PCE print as the main trigger for rate-exposed positioning, not the current probability alone.
• Oil supply risk: Brent's decline to $88 reflects an Iran-Oman revenue-sharing deal, not a secured reopening of Hormuz. Ukrainian drone strikes on Russian refineries and ports remain a live physical supply risk that could reverse the equity reaction in oil majors.
• AI exposure: Nvidia's 70% revenue forecast and Salesforce's 20.5% gain show demand strength, while Microsoft, Oracle, Micron and AMD followed. The Anthropic and OpenAI IPO expectations remain a sentiment driver until actual issuance details emerge.
• Kazakhstan equities: Kazatomprom's affirmed BBB rating and KazTransOil's 33.4% net profit growth are company-specific supports; Halyk Bank's 3.4% drop is tied to the dividend register closure rather than an earnings warning.
• Idiosyncratic risks: Meta's $16.7 billion settlement is a reminder that regulatory costs can arrive suddenly; cryptocurrency-linked ETF gains of 3.5% to 20.5% show risk appetite but remain volatile.
