Trading across Asian markets produced a split picture on Tuesday, while contracts tied to Wall Street pointed higher after the previous session had pushed equities to within reach of an all-time closing peak. Crude benchmarks held relatively flat as geopolitical tensions across the region kept traders on edge.

Trading in Tokyo pushed the Nikkei 225 index up by half a percentage point, with the benchmark closing at 70,321.83. Trading activity this week pushed the index back past the 70,000 threshold, a level it had not held since early July. Trading on the Kospi index pulled back by around one percentage point, with the benchmark settling at 6,936.60.

Shares tied to the tech sector across Japan and South Korea saw their prices swing in both directions throughout the session. Advantest, which makes chip-testing equipment, posted a 2% gain in its share price, while SoftBank Group — a founding investor in OpenAI — fell 2.5% after chief executive Masayoshi Son outlined reservations about the potential downsides of the technology. Shares in Samsung Electronics retreated 1.6%, while SK Hynix — a maker of memory chips — gave back 2.9% of its value.

Trading in Hong Kong pushed the Hang Seng index up by 0.8 percent, with the benchmark settling at 24,228.47. Gains of 0.6 per cent lifted the S&P/ASX 200 to a reading of 8,735.20 on the Australian bourse. Fractional moves defined the session for two Asian benchmarks — Taiwan's Taiex slipping a tenth of a percent while India's Sensex picked up two-tenths. Markets across China's mainland went untraded that day, the exchanges having remained closed in observance of a national holiday.

The S&P 500 edged upward by 0.7% on Monday, pulling within reach of an all-time peak. Trading closed with the Dow Jones Industrial Average up 0.2%, while the Nasdaq composite pushed 1.1% higher to finish at a record level. Chipmakers led the advance, with both Nvidia and Broadcom each posting a 2.1% uptick in their share prices.

Elevated oil prices and rising bond yields have weighed on equities and corporate outlooks alike, though anticipation of robust quarterly earnings has underpinned the market's recent upward momentum heading into the new reporting period.

Crude benchmarks ticked upward in the hours after Tuesday's trading opened. Priced at $100.71 per barrel, Brent crude — the globally recognised benchmark — had gained 0.4% on the day, a level roughly $28 above where it traded at the end of February. West Texas Intermediate crude edged up a third of a percent, landing at $89.73 a barrel.

Oil volumes transiting the Strait of Hormuz have shown an uptick, and flow data along Saudi Arabia's East-West pipeline point toward a gradual regional recovery — yet price pressure has not fully eased, as traders continue to factor in the possibility of supply disruptions tied to the unresolved diplomatic standoff between the United States and Iran. One market analyst noted that pipeline and strait readings, while trending toward stabilisation in the Gulf, have not been enough to dispel lingering uncertainty among those active in energy markets.

In a Tuesday commentary, ING commodities strategists Warren Patterson and Ewa Manthey noted that the conditions were holding prices at elevated levels for the time being.

Yields on U.S. Treasury debt held close to levels not seen in decades. Touching 5.35% at its peak — a rate not seen since 2002 — the 10-year U.S. Treasury yield settled at roughly 5.32%, up from the 5.28% recorded the previous Friday. Bond markets are demanding higher yields on government debt, with price pressures building partly on the back of an energy disruption tied to the conflict involving Iran, alongside a national debt load that has crossed the $40 trillion threshold for the first time.

Against the previous session, the dollar edged up to 157.96 yen per unit from a prior reading of 157.91. Against the prior session's close of $1.1223, the euro changed hands at $1.1222.
