As the Federal Reserve gears up for its upcoming policy meeting, President Donald Trump has once again asserted that interest rates in the United States should be the lowest in the world.

Speaking to reporters on September 13 during the Irish Open golf tournament, Trump stated he was uncertain whether Fed policymakers would implement a rate hike this week. However, he insisted that regardless of the inflation and economic data before the central bank, the U.S. "ought to be paying the lowest rate" globally.

The consumer price index (CPI), a critical gauge of underlying inflation released by the Labor Department, posted its largest increase in four months last Friday. This has solidified market expectations that the Federal Open Market Committee (FOMC), concluding its meeting on September 16, will raise the federal funds rate target range, currently set between 3.5% and 3.75%.

This pivotal Fed gathering occurs just weeks before the midterm elections, which will decide whether Republicans can preserve their slim majorities in both chambers of Congress. With domestic inflation persisting, Trump's approval ratings have been on the decline.

On September 13, Trump reiterated his claim that the current interest rate levels are benefiting other nations at America's expense. "I know the formulas better than anybody. We have the best credit in the world, and we're making other countries rich," he said.

While Trump has often criticized former Fed Chair Jerome Powell in the past, his tone toward the central bank's leadership has softened since Kevin Warsh, his personal pick, assumed the role of Fed Chair earlier this year. Nevertheless, Trump has recently intensified his pressure on the institution.

Two weeks prior, he took to social media to warn: "Cut rates, or I will stop trading with countries that have trade deficits with us!" Later on September 13, as he prepared to board a flight back to the U.S., Trump reinforced this threat, stating, "We don't want to have deficits with countries. We want to have surpluses, or at least break even."

Kevin Hassett, Director of the White House National Economic Council, appeared on Fox News that same day to say that no matter how the Fed ultimately handles interest rates, Trump would "defend Kevin Warsh's independence" above all. However, Hassett also underscored Trump's own policy leanings, noting that if the Fed raises rates, "I'm sure he won't be too happy about it."
