Federal Reserve chief Kevin Warsh is facing mounting pressure from former President Donald Trump regarding the central bank's interest rate policy. Trump has publicly advocated for lower interest rates, a stance that clashes with market expectations and recent economic data suggesting a potential rate hike.

Surging U.S. job numbers released in August, which showed the economy added 162,000 jobs – significantly exceeding the projected 56,000 – have increased the likelihood of the Federal Reserve raising interest rates. This development has also led to fluctuations in bond markets.

Following the job report, financial markets have escalated their bets on a quarter-percentage-point rate increase by the Fed this month. However, Trump expressed a contrary view on social media, stating, "A strong country means a lower interest rate." He further criticized the Fed, urging its board to "get smart – be patriots for a change" and even threatening to halt trade with countries with which the U.S. has a trade deficit unless they lower their own rates.

This public disagreement places significant pressure on Warsh, who was appointed by Trump to lead the Federal Reserve earlier this year. Trump had previously criticized his predecessor, Jerome Powell, for not lowering rates.

Markets, conversely, are increasingly convinced that the Fed will need to raise rates to combat persistent inflation. Kathleen Brooks, research director at XTB, described the situation as a "big test for Warsh," noting that how the new chairman responds to Trump's demands will significantly impact the Federal Reserve's independence and global bond markets.

Warsh has previously signaled a readiness to address inflation. In a speech at the annual central bankers' gathering in Jackson Hole, Wyoming, he indicated a willingness to act. The recent non-farm payroll figures, despite economic pressures from oil price shocks related to the Iran war, suggest the U.S. job market is robust enough to withstand a rate increase.

Stephen Brown, chief North America economist at Capital Economics, commented that even a dovish economist would find it difficult to justify keeping interest rates unchanged based on the August employment report. Attention is now shifting to upcoming U.S. inflation figures, with the Federal Reserve's decision on interest rates scheduled for September 16.

The recent economic data also caused renewed volatility in bond markets. Ten-year U.K. gilt yields, for instance, saw an increase, remaining elevated after reaching an 18-year high earlier in the week.
