Nvidia earnings and Jackson Hole: What to watch this week

The United States Federal Reserve's new chair, Kevin Warsh, faces a critical test this week as global bond markets experience anxiety over mounting inflation and Donald Trump's fiscal policies. The Jackson Hole conference, a significant annual gathering of the world's most influential central bankers, provides Warsh with a platform to signal the Federal Reserve's stance on inflation.

However, Warsh's reluctance to offer detailed commentary on interest rate decisions has raised concerns among investors. Dan Coatsworth, a broker at AJ Bell, suggests Warsh's speech could provide "a comfort blanket" to investors seeking reassurance. James Smith, an economist at ING Bank, warns that less guidance on future interest rates could inject volatility into an already tense bond market.

The annual meeting coincides with a surge in selling pressure in the US government debt market, exceeding $30tn, driven by concerns over inflationary effects of the Iran conflict and the country's record-high national debt surpassing $40tn. Despite Treasury Secretary Scott Bessent's efforts to ease investor fears through increased Treasury bond purchases, the yield on long-term US Treasury debt has fluctuated.

Warsh's cautious approach to inflation concerns in his July press conference, combined with President Trump's calls for rate cuts, has left investors uncertain about the Fed's future actions.
