The broader context here is that stocks and bonds were repriced together. Think of higher rates as stronger gravity pulling down what future profits are worth today. Growth companies feel that pull most. Other companies feel it when it costs more to renew loans.
In my view, the order matters. Bond weakness led. Equities followed. Stronger crude then added pressure through household budgets and business costs. That mix can lower stock values and make future profits harder to predict, with sharper swings when rates and oil rise together.
Looking at what this means for the September 15-16 FOMC, the committee meets with financial conditions tighter than before. Short-term rates show what markets expect for Fed policy. Long-term rates show extra pay for inflation, supply and uncertainty. Sorting out those parts will shape the statement, the rate forecasts and the press conference. Trading conditions into the decision bear watching.
