US dollar:

As of 11:41, the US dollar index rose 0.07% to 100.29. Minneapolis Fed President Neel Kashkari said that US inflation remains too high, and the pressure has gone beyond the oil price shock caused by the Iran war, spreading to multiple areas of the economy. The inflation felt by the American public every day is far more than just an oil price issue; it exists in every aspect of the economy. Kashkari said the US Fed is increasingly concerned that inflation is not only concentrated in areas affected by the Middle East conflict or tariffs, but that signs of inflation are also emerging in the services sector. He said the Fed's job is to bring inflation back to target and it has the tools to do so. Kashkari was one of three dissenters in the July decision to hold rates steady, when he favoured a hike and warned that waiting too long could entrench inflation, ultimately requiring more aggressive action. Kashkari believes the US economy, despite facing geopolitical conflicts and trade issues, is still showing strong resilience and the labour market remains robust. He hopes that as the impact of some conflicts gradually fades, economic growth can take over as a driver, the pace of disinflation can accelerate, and pressure on Fed policy can ease.

According to CME "FedWatch": the probability of the Fed holding rates steady at 3.75%-4.00% at the October meeting is 43.5%, and the probability of a 25bp hike is 56.5%. The probability of the Fed holding rates steady at 3.75%-4.00% by December is 10.2%, the probability of a cumulative 25bp hike is 46.6%, and the probability of a cumulative 50bp hike is 33.3%.

Oaktree Capital Management Co-Chairman Howard Marks said he would prefer a Fed that communicates less. Fed Chairman Warsh is seeking to scale back some of the guidance measures, which Warsh has previously said have constrained the central bank's room for manoeuvre in recent years. Marks said on Sunday: "Personally, I would rather see a less activist Fed. Normally the Fed should let the economy run on its own unless it faces a risk of running out of control, such as overheating or overcooling." Marks said reducing policy guidance means investors must make their portfolios antifragile, which is good for society. Marks also called for the creation of an artificial intelligence task force to study how AI will affect key areas of the economy, such as the job market. (Jin10 Data APP)

In other currencies:

Societe Generale analyst Jin Kenzaki said in a report that the Bank of Japan may hike rates once every other meeting, bringing the terminal rate to 2% by June 2027. Kenzaki said that at the press conference following the BoJ's rate hike on Friday, Governor Kazuo Ueda noted that with underlying inflation approaching the 2% target, the central bank's next focus is whether inflation will stabilise at that level. Ueda also said next year's spring wage negotiations will be a key factor in making that assessment. Societe Generale expects the solid momentum seen in wage negotiations to continue into next year.

Westpac Chief Economist Luci Ellis has brought forward expectations for RBA interest rate hikes to September, saying the central bank governor's remarks met the conditions for further tightening set by the board in August. She acknowledged there were tactical reasons to wait, including the release of August monthly CPI the day after the meeting, as well as the potential for awkward optics if the Middle East situation eased slightly, fuel excise adjustments were made, or a weak jobs report emerged. But she concluded that the weight of hawkish commentary outweighed these factors. Westpac expects the vote to be split, citing differing views on trend productivity, labour supply, and the degree of slack in the labour market, while the underemployment rate has risen sharply.
