Dollar nudges higher ahead of US inflation data; Aussie gains on rate bets

LONDON/SINGAPORE, Aug 26 (Reuters) - The dollar edged higher but remained range-bound against major peers on Wednesday as investors awaited U.S. inflation data that could set the tone ahead of the Jackson Hole symposium ‌of central bankers later this week.

The most notable mover was the Australian dollar, which hit $0.71865, its highest level in three ‌months, after data showed the trimmed mean CPI gauge, the Reserve Bank of Australia's preferred measure of cost-of-living pressures, rose at a faster-than-expected annual rate of 3.6%.

It was ​last up 0.24%, just below that level.

"With underlying inflation showing no signs of slowing, there's still a risk that the RBA will deliver another rate hike over the coming months," Capital Economics analysts wrote in a research note.

Aside from the Swiss franc, against which the dollar rose 0.3% to 0.8036 francs, moves in the most traded currency pairs were muted ahead of a potentially pivotal few days for markets.

The dollar climbed 0.1% against ‌the Japanese yen to 158.95 yen, while sterling ⁠slipped 0.2% to $1.3624.

The euro was also a touch weaker at $1.1664, shrugging off a Reuters report citing sources saying ECB policymakers are prepared to raise interest rates at their September meeting but have little appetite to signal ⁠further tightening.

Traders were focused on the release of July U.S. personal consumption expenditures (PCE) data later in the day, ahead of Federal Reserve Chair Kevin Warsh's keynote speech at Jackson Hole on Friday.

The conference, with its global audience and intense media coverage, offers Fed officials a high-profile platform ​to signal ​policy thinking or reinforce existing messages.

PCE is the Fed's preferred inflation gauge. ​Economists polled by Reuters expect core PCE, which excludes ‌food and energy, to have risen 3.3% in July from a year earlier, unchanged from June and well above the Fed's 2% target.

If forecasts prove correct, traders will look for clues from Warsh on whether further rate hikes may be needed to bring inflation back to target. Some analysts say the recent rise in long-dated Treasury yields suggests the Fed may need to do more.

Treasury Secretary Scott Bessent's decision to intervene in the market in an attempt to lower bond yields has added another layer of complexity, though analysts do not expect a ‌great deal of explanation from Warsh's remarks.

"Normally, this would be an event awaited ​with great anticipation where the Fed would be prepared to lay out its future ​monetary policy strategy or even signal major policy regime shifts," ​said Benoit Anne, senior managing director at MFS Investment Management.
