The U.S. dollar traded within a narrow range on Thursday as investors awaited fresh signals from the Jackson Hole economic symposium, while the Japanese yen remained largely unchanged after a Bank of Japan policymaker left the door open to a possible interest rate increase next month.

Currency markets were relatively subdued as traders assessed competing signals on monetary policy from the United States, Japan and other major economies.

The euro edged 0.05% higher against the dollar to $1.1655, while the British pound slipped 0.05% to $1.3586. The Australian dollar strengthened 0.18% against the greenback to $0.718.

The yen was little changed at 159.30 per dollar after Bank of Japan Deputy Governor Ryozo Himino said timely increases in interest rates could help prevent inflation from accelerating sharply and forcing the central bank into more aggressive tightening later.

Himino’s comments were closely watched because investors are trying to determine whether the Bank of Japan will raise interest rates at its Sept. 17-18 policy meeting.

However, the deputy governor stopped short of giving the kind of explicit signal that policymakers have previously used to prepare markets for an imminent rate increase.

That cautious approach limited the yen’s reaction and left traders searching for additional clues from other Bank of Japan officials in the weeks ahead.

Financial markets had been pricing a strong possibility of a September rate increase, with money markets putting the probability at about 86%.

Investors are also trying to determine how quickly the central bank could continue tightening monetary policy if another increase is delivered.

Sho Suzuki, a market analyst at Matsui Securities, said Himino’s comments highlighted concerns about upward pressure on prices, making the remarks less dovish than some investors may have expected.

At the same time, the absence of a direct signal about a September increase leaves room for the yen to come under renewed pressure, particularly if U.S. interest rates remain relatively high.

The yen has been under pressure for much of the year as the gap between U.S. and Japanese interest rates continues to influence currency flows.

A higher Bank of Japan policy rate could provide some support for the Japanese currency by making yen-denominated assets more attractive. But traders remain cautious because the timing and pace of future increases are still uncertain.

The dollar index, which measures the U.S. currency against a basket of major currencies including the euro and yen, was steady at 99.13 after retreating from an eight-day high reached earlier.

Attention was increasingly turning to the Federal Reserve’s annual gathering in Jackson Hole, Wyoming, where investors were looking for guidance on the future direction of U.S. monetary policy.

Recent inflation data have complicated expectations for the Federal Reserve.

U.S. data released Wednesday showed the Personal Consumption Expenditures price index increased 3.7% in the 12 months through July, unchanged from June and slightly above economists’ expectations of 3.6%.

On a monthly basis, the index rose 0.2% in July after declining 0.1% in June. Economists had expected a 0.1% monthly increase.

The figures indicated that inflation remains persistent and could make policymakers more cautious about easing monetary policy.

The inflation reading kept expectations for a possible Federal Reserve rate increase by the end of the year alive. Investors were therefore focused on comments from Federal Reserve Chairman Kevin Warsh at the Jackson Hole symposium for clues about how officials view the inflation outlook and the appropriate path for interest rates.

Westpac economist Ryan Wells said the chairman’s speech would be an important test for those expectations.

The dollar’s performance in the coming sessions could depend heavily on whether Federal Reserve officials emphasize the need to keep interest rates elevated to contain inflation or indicate that monetary policy could become less restrictive if price pressures moderate.

Elsewhere in Asia, the South Korean won strengthened 0.39% against the dollar to 1,379.9 after the Bank of Korea raised its benchmark interest rate by 25 basis points to 3%.

The increase marked the second consecutive rate hike by the South Korean central bank and provided support for the won.

The Canadian dollar was largely unchanged at C$1.388 per U.S. dollar as investors continued to monitor tensions between Washington and Ottawa.

U.S. President Donald Trump said Wednesday that it was time to take a tougher approach toward Canada, days after trade negotiations between the two countries broke down.

The comments added another source of uncertainty for the Canadian currency as markets assessed the potential economic consequences of renewed trade tensions between the two neighbors.

The currency market’s broader mood remained cautious, with investors balancing interest-rate expectations against geopolitical and trade developments.

In cryptocurrency markets, bitcoin gained 0.26% to $78,640.95, while ether rose 0.46% to $2,483.27 after giving up some of its earlier gains.

For currency traders, the focus remains firmly on central-bank policy. Signals from the Federal Reserve and Bank of Japan could determine whether recent moves in the dollar and yen develop into more sustained trends.

With U.S. inflation still above the Federal Reserve’s comfort zone and Japanese policymakers increasingly concerned about domestic price pressures, investors are preparing for a period in which even small changes in central-bank language could trigger significant moves in global currency markets.
