The Globe and Mail reports in its Tuesday edition that $100-(U.S.)-a-barrel oil is back on the table for the first time since 2022, when Russia invaded Ukraine. The Globe's Mark Rendell writes that historically, oil price shocks have negatively affected the economy and stock market, as seen in the 1970s, 1980s and 1990s. Despite a shaky start on Monday, financial markets stabilized by noon, suggesting low likelihood of a significant downturn. Rationalizing a single day's trading is futile, especially when a major conflict in a top oil-producing region is met with indifference. It seems investors are becoming more strategic, as markets typically overlook conflicts in the long run. Panic selling at the first sign of trouble can be risky. Economist David Rosenberg says: "Never let geopolitics get in the way of your investment decisions. Had you bet against the stock market from the last military conflict which lasted around two weeks in June, 2025, you would have made a bad decision." Economist Paul Krugman says: "I don't want to engage in doomsaying. But I do worry that people are too complacent about the economic risks this war creates." Analysts see oil prices well over $100 if the conflict lasts more than a few weeks.
