SINGAPORE, Sept 8 (Reuters) – The yen surged on Tuesday, while Asian markets struggled for direction as a mixed batch of regional economic data and fresh Iranian threats in the Persian Gulf drove oil prices ​and bond yields higher.

Japan’s Nikkei 225 fluctuated between gains and losses before ‌edging up 0.2%, as the yen jumped as much as 0.6% to 153.51, its strongest level since February 18.

MSCI’s broadest index of Asia-Pacific shares outside Japan was up 0.2%, led by a 1.2% gain in the KOSPI. S&P 500 e-mini futures were down 0.1% after a holiday in the U.S. on Monday.

“While ‌U.S. ​Labor Day made for a somewhat quieter start to ⁠the week for trading volumes, ⁠the weekend’s tit-for-tat strikes between the U.S. and Iran continued to put upward pressure on oil prices, acting as a drag on risk sentiment more broadly,” Westpac analysts said.

Oil prices moved higher for a third day as trading resumed in ​Asia, with Brent crude futures edging up 0.04% to $97.04 a barrel, after hitting a six-week high on Monday after Iran threatened to retaliate against any new attacks by targeting ⁠energy infrastructure across the Gulf, including U.S. oil ⁠and gas interests.

The yield on the U.S. 10-year Treasury bond was ​up 0.6 basis points at 4.788%. Traders are still pricing an implied 60% probability of ​a 25-basis-points hike at its next two-day meeting on September 16, ‌according to the CME Group’s FedWatch tool, about the same chance as a week ago.

The U.S. dollar index, which measures the greenback’s strength against a basket of six currencies, was trading around a two-week low of 98.82.

On the broader economic front, the growth picture appeared ⁠mixed as data released Tuesday blew hot and cold.

Japan’s economy grew faster than initially estimated in the April-June quarter from the previous three months, supported by business spending, revised data ⁠showed on Tuesday, but ‌the figure still lagged analysts’ forecasts.

Meanwhile, data showed Japanese real wages ⁠rose 2.4% in July from a year earlier, marking the ​biggest ‌increase since May 2021.

“With wage growth going from strength to ​strength, the case ⁠for the Bank of Japan to hasten the pace of tightening is becoming increasingly compelling,” Capital Economics analysts wrote in a research report.

Over in Australia, shares slumped 0.6% after a measure of local consumer sentiment fell sharply in September.

Gold was up 0.5% at $4,428.23, while in cryptocurrencies, bitcoin nudged 0.1% higher to $79,333.01, while ether climbed 0.2% to $2,498.94.
