What caused the Nikkei 225 to drop today?

The Nikkei 225 fell on a sharp risk-off move driven by an oil price spike tied to Iran tensions and weaker China PMIs. Higher crude raises input costs and inflation risks, while soft demand signals pressure earnings. Together, they cut risk appetite and pushed investors to trim exposure to cyclicals and financials.

How could higher oil prices affect Canada?

Higher crude can lift cash flows for Canadian energy producers and support related employment. It can also raise fuel and shipping costs, adding to inflation pressures. That may slow Bank of Canada cuts and weigh on rate-sensitive sectors. Portfolios often see wider dispersion, with energy and quality cash-flow names holding up better.

Should I change my portfolio after an Asia stocks selloff?

Avoid knee-jerk moves. Review exposures to energy, cyclicals, and rate-sensitive names. Ensure diversification, maintain a cash buffer, and consider modest hedges. If your thesis is intact, use watchlists and staged entries to add quality at better prices. Reassess risks if oil stays high and earnings revisions turn negative.

What indicators should Canadians watch next?

Track oil supply headlines tied to Iran, China PMIs for demand, and Canada or US inflation prints for policy direction. Monitor credit spreads, central bank speeches, and earnings guidance quality. If the Nikkei 225 remains weak while crude stays firm, expect continued rotation toward energy and higher-quality balance sheets.
