How does the WTI oil price affect the Nikkei 225 outlook?

A higher WTI oil price lifts import costs, which can compress margins for energy-intensive sectors. If firms struggle to pass costs through, earnings guidance may turn cautious. That can cool risk appetite and pull the Nikkei 225 lower, especially if the yen stays weak and global rates remain restrictive.

What signals matter most in the S&P 500 selloff right now?

We watch RSI near 35, MACD below signal, and price versus the 50-day and 200-day averages. The index hovering around its 200-day suggests a fragile trend. If breadth stays soft and the WTI oil price holds high, rallies may fade faster, making risk management and sizing more important.

How could the Hormuz Strait risk spill into Japan markets?

Any disruption near Hormuz can raise shipping and insurance costs, which may push the WTI oil price higher. Japan, as a large crude importer, could see pressure on energy-sensitive sectors and consumer spending. A drawn-out disruption would likely tighten financial conditions and keep equity volatility elevated.

What should retail investors in Japan focus on this week?

Prioritize balance sheets, cash flow, and pricing power. Use staggered buys, consider defined-risk hedges, and watch the Fed’s tone. If the WTI oil price eases below $90, risk may improve. If it holds near $100, expect choppy trading and stick to disciplined sizing and clear exit rules.
