What is the Strait of Hormuz and why does it matter to markets?

It is a narrow waterway between Oman and Iran that handles a major share of global seaborne oil. Any threat to shipping can lift insurance costs, delay cargoes, and raise crude prices. That filters into inflation, rates, and equity risk, affecting Canadian fuel bills and portfolios.

How could G7 oil reserves be used if supply stays tight?

Energy ministers can coordinate strategic stock releases to offset shortfalls or calm panic buying. Even modest, time-bound draws can cut extreme price spikes and narrow volatility. The goal is to bridge temporary disruptions, not to replace normal production or long-haul supply routes.

What does Macron’s defensive mission aim to achieve?

France is working on an international escort plan to protect tankers and progressively restore safe passage. The aim is to reduce risk premia and stabilize flows without widening the conflict. Effective coordination can reassure insurers and shippers, which helps cool prices and volatility.

How should Canadians position around the S&P 500 today?

Use levels and signals. Price is below the 50-day but above the 200-day, with RSI near oversold. Keep position sizes modest, add in stages, and manage stops. Consider energy sensitivity for the TSX, and watch the Canadian dollar’s response to oil headlines before rebalancing.
