Central Bankers Meet at Jackson Hole Amid War, Bond Market Turmoil

The world's leading central bankers converge on Jackson Hole, Wyoming, this week for their annual symposium, convening against a backdrop of heightened uncertainty. The gathering comes six months into the Iran war, with global bond markets still on edge following a selloff in long-dated U.S. debt that prompted intervention by the U.S. Treasury.

Federal Reserve Chair Kevin Warsh is set to deliver the keynote address, facing a choice between outlining long-term structural reforms for the central bank or offering more immediate guidance on monetary policy. Investors, still digesting the recent bond market volatility, are eager for clarity on the path of interest rates. Warsh has so far signaled reluctance to provide explicit forward guidance, a stance that may come under strain given market conditions.

Inflation remains a central concern, exacerbated by the prolonged closure of the Strait of Hormuz and rising crude prices. Brent crude is on track for its second consecutive weekly gain, but the sharp increase in refined products is drawing particular attention as the Northern Hemisphere approaches winter. European diesel prices have surged over 70% since the war began in February, while U.S. gasoline prices are up 60%. With refining output curtailed across the Middle East, Russia, and East Asia, energy-driven inflation appears persistent.

A clearer picture of global price pressures will emerge this week with inflation data due from Australia, France, Spain, and Tokyo. The focus will be on the U.S. core PCE reading, expected to remain above the Fed's 2% target for the 65th consecutive month.

Investors will also look to Nvidia's second-quarter earnings on Wednesday as a barometer for the artificial intelligence investment boom. The chipmaker's results could influence whether enthusiasm for AI remains strong enough to support elevated tech valuations, especially after a recent selloff driven partly by rising bond yields. Key attention will be on demand from major cloud providers, whose spending has fueled Nvidia's growth.

Elsewhere, South Korea's central bank meets on Thursday, with markets watching for a possible follow-up to July's first rate hike in 3-1/2 years. Inflation cooled to 2.8% annually but remains above target, while AI-related chip demand continues to support the economy. A hike could pressure stocks but boost the won, which has strengthened over 10% this month. Thailand's central bank also meets, though rates are expected to stay on hold.

In Iceland, voters head to the polls on August 29 for a referendum on whether to revive EU accession talks frozen since 2013. The vote is not on joining the bloc itself, but polls suggest the nation is evenly split. A 'yes' would reopen negotiations with Brussels, with fisheries likely a major sticking point; a 'no' would further cool the EU's enlargement ambitions.
