Nikkei Rebounds as Oil Slump Boosts Cyclicals; AI Stocks Struggle

Cyclicals Lead as Oil Slide Eases Cost Fears

The Nikkei 225 closed up 320.04 points, or 0.50%, at 64,931.19 on Monday, reversing a portion of recent losses as a drop in crude oil prices lifted economically sensitive cyclical stocks. AI and semiconductor names, which had led earlier rallies, remained under pressure. The broader TOPIX index firmed throughout the session, ending in positive territory even as the Nikkei briefly dipped into the red in choppy trade.

WTI crude futures slid to around $83 per barrel after Washington announced a temporary halt to military strikes on Iran, easing immediate supply disruption fears. In response, investors rotated into sectors that benefit from lower input costs and stronger economic activity — air transport, rubber products, services, and financials all gained. Financial stocks drew extra support from positioning ahead of this week's Federal Reserve and Bank of Japan policy meetings, with traders betting on a supportive interest-rate environment.

From the open, the Nikkei jumped nearly 0.9%, then erased those gains and briefly fell 0.75% before recovering into a tight range. The intraday swings reflected a tug-of-war between bargain hunters in value stocks and persistent caution around high-growth technology names. Of the Tokyo Stock Exchange's 33 industry sectors, 29 advanced, led by air transport and other products, while only nonferrous metals and mining — sensitive to the same oil-price move — declined.

The Forces Behind the Rotation: Global Oil, Policy Bets, and a Pause in Tech Euphoria

The Oil-Geopolitics Link

The temporary pause in US strikes on Iran was the immediate catalyst for crude oil's retreat. With WTI slipping well below the $85 handle, industries that are heavy consumers of fuel or that benefit from cheaper energy — such as airlines, rubber manufacturers, and broad services — suddenly looked more attractive. The rally in these names is as much a relief trade as it is a genuine rotation: if the military pause proves short-lived, oil could rebound quickly, reversing the trade. For now, markets are treating the de-escalation as a window of opportunity to reprice cyclical shares that had been suppressed by elevated energy costs.

Central Bank Anticipation Lifts Financials

Financial stocks, which tend to perform well when interest rates are stable or rising, got an extra lift from the policy calendar. The Federal Reserve concludes its two-day meeting on Wednesday, and the Bank of Japan follows with its own decision later in the week. While neither is expected to deliver a shock, the prospect of even subtle shifts in forward guidance is enough to prompt positioning. Any signal that the Fed might delay rate cuts, or that the BOJ is moving closer to policy normalisation, would further boost the value trade that favours financials and cyclical names.

Tech Fatigue and the Semiconductor Overhang

AI and semiconductor shares remained an underweight. The market is growing anxious about whether the enormous capital expenditure on AI infrastructure is yet translating into commensurate revenue — a question that will be tested when US hyperscaler cloud companies and Japanese-Korean memory chipmakers report earnings this week. Daiwa Securities strategist Daisuke Hashizume pointed to persistent uncertainty around the chip outlook as fuelling a risk-off shift to cyclical stocks. Until the earnings reports offer clarity, the trade is cautious: investors are unwilling to chase tech names that may face further derating if guidance disappoints.

Key Events That Could Define the Week Ahead

• The Federal Reserve's policy statement on Wednesday and the Bank of Japan's decision later this week are the immediate macro signposts. Any hawkish tilt could accelerate the rotation from growth to value, reinforcing the current cyclical trade.
• Crude oil prices remain the swing factor. The US-Iran pause is fragile; any resumption of hostilities could swiftly lift energy costs and reverse Monday's gains in transportation and services stocks.
• Earnings from global hyperscaler cloud providers and memory chip manufacturers due this week will be a critical test for the AI investment thesis. Weak capex guidance or cautious demand outlooks would likely extend the sell-off in semiconductor names that faltered Monday.
• The broad sector advance — 29 of 33 groups rose — suggests dip-buying interest is broadening beyond tech. Traders may want to watch whether volume supports a sustainable rotation or if it fades as earnings season intensifies.
