Asia Markets Today: Yen Firms, Aussie Falls, Oil Slips
Asian Session Report: Yen Firms Near 156.40 on Half-Year-End Flows as Aussie Hits Two-Month Low After 4.0% CPI
Asian markets rebounded on Wednesday as oil extended Tuesday’s slide on SPR-release and Russia-sanctions reports. USD/JPY fell from about 157.50 to near 156.40 on Japanese half-year-end flows and fresh verbal warnings from Tokyo, even after weak factory output (-1.7% m/m) and retail sales. The Nikkei rose about 1.0%, the KOSPI faded to a 0.1% loss after opening higher, and the Hang Seng was flat.
Australian August CPI printed 4.0% y/y with trimmed mean at 0.2% m/m, softer than hoped, trimming November RBA hike odds to roughly 20-25% and pushing AUD/USD to a two-month low near 0.6950. China’s official PMIs returned above 50. The US 30-year yield closed near 5.59% after touching 5.62%, the highest since 2002, while gold hovered just under $4,200. Next up: US PCE, Micron results and Friday’s payrolls.

Yen gains as quarter-end selling and intervention warnings collide with hawkish Fed bets
Exporters sold dollars into the fiscal half-year end, and Japan’s top currency diplomat repeated last week’s warnings. Data on any Aug 27-Sep 28 yen buying is due from the Ministry of Finance.
Headline CPI hits 4.0% but trimmed mean cools, easing pressure on the RBA
Fuel jumped 14.8% m/m. Trimmed mean rose 0.2% m/m (0.3% expected) and held at 3.6% y/y. The RBA lifted rates to 4.60% on Tuesday; markets now see about a 20-25% chance of a November follow-up.
Oil slips again as SPR offer and sanctions-relief reports outweigh stalled US-Iran talks
Brent settled near $103 on Tuesday. The US offered up to 40M barrels from the SPR, and Goldman says Gulf exports are back at their 2025 average. Axios says Qatar-led talks made little progress.
Nikkei rallies, KOSPI fades as Asia awaits PCE and Micron
The KOSPI (Tuesday close 6,870.81) gave back early gains on weak data and DMZ tension. China PMIs improved to 50.1 (official) and 52.1 (RatingDog) before mainland markets close Oct 1-7 for National Day.
Technical Summary
USD/JPY
FX · Yen bid on intervention warnings and quarter-end flows
The pair slipped from 157.50 back under its 20-day moving average as Japanese officials, backed by the US Treasury, stressed cooperation on yen weakness and the BoJ (1.25% after its 18 Sept hike) stays on a tightening path. Hawkish Fed speakers and 5%+ US yields limit the downside, so rallies into 157.00 are the fade area; a hold above 157.60 would cancel the idea and reopen 158.00.
| Resistance | Support |
|---|---|
| R1157.00 | S1156.00 |
| R2157.60 | S2155.40 |
| R3158.00 | S3154.80 |
AUD/USD
FX · Soft core CPI cools RBA hike bets; DXY near 101.3
AUD/USD has lost the 0.7000 handle for a third straight day despite the RBA hike, with RSI near oversold and price under its moving-average cluster. Stronger China PMIs did little for the Aussie, and the AU-US 2-year spread is narrowing. Rebounds toward 0.7000-0.7026 (200-day SMA area) are a sell zone; a daily close above 0.7030 would stall the downtrend.
| Resistance | Support |
|---|---|
| R10.7000 | S10.6950 |
| R20.7026 | S20.6900 |
| R30.7068 | S30.6831 |
Aluminium (LME 3M)
Metals · Tight supply versus a firm dollar
Gulf output is down about 44% y/y and LME stocks sit near a 36-year low, keeping the physical market tight. Offsets are a stronger dollar, smelter restarts and Chinese exports up 17.2% y/y in August. The metal is range-bound between $3,230 and $3,290; a break above $3,290 opens $3,330, while a close under $3,205 would signal fading demand.
| Resistance | Support |
|---|---|
| R1$3,290 | S1$3,230 |
| R2$3,330 | S2$3,205 |
| R3$3,375 | S3$3,150 |
Wheat (CBOT Dec)
Grains · Black Sea talks and US-China tariff cuts cap rallies
Wheat slipped under $7 for the first time in a month on Black Sea shipping mediation and agricultural tariff reductions in the US-China deal, and sits near its lowest since 25 August. Large fund longs and a two-month-high dollar add pressure. A bounce toward $7.00 is a fade area; a settle above $7.08 would neutralise the bearish setup.
| Resistance | Support |
|---|---|
| R1$6.99 | S1$6.88 |
| R2$7.08 | S2$6.75 |
| R3$7.25 | S3$6.60 |
KOSPI
Indices · Chip-led index awaits PCE and Micron
The index opened up 1.2% near 6,951 on a Philadelphia semiconductor rally, then faded as foreign selling persisted (about 3 trillion won on Tuesday). It held above Tuesday’s 6,780 intraday low. Micron results (after the US close) and PCE are the swing events, so size small; a clean move over 6,950 targets 7,000, while a break of 6,740 exposes the mid-September 6,600 area.
| Resistance | Support |
|---|---|
| R16,950 | S16,780 |
| R27,000 | S26,740 |
| R37,080 | S36,600 |
Dogecoin (DOGE/USD)
Crypto · Leverage-driven bounce while yields cap risk assets
DOGE has recovered about 13% over the month but analysts note the bounce leans on leverage rather than fund buying, and it remains roughly 59% below its level a year ago. Bitcoin near $84,000 and record-high long-bond yields keep risk appetite fragile. Holding $0.0930 keeps $0.0982 and $0.1000 in play; a slip under $0.0905 would signal the rebound is fading.
| Resistance | Support |
|---|---|
| R1$0.0982 | S1$0.0930 |
| R2$0.1000 | S2$0.0905 |
| R3$0.1040 | S3$0.0850 |
Litecoin (LTC/USD)
Crypto · Underperforms DOGE as majors stay heavy
Litecoin is down about 1.3% while DOGE bounces, a sign of weak relative strength. With the 30-year yield near 5.6% and PCE due, rallies into $70 look like fade areas. A break of $67.00 opens $65.00; a close above $71.20 would end the bearish view. Levels beyond sourced quotes are indicative.
| Resistance | Support |
|---|---|
| R1$70.00 | S1$67.00 |
| R2$72.50 | S2$65.00 |
| R3$75.00 | S3$62.50 |
What to Expect from the Next Session
- US PCE and GDP. Headline PCE is expected near 3.7% y/y and core near 3.4%; a hotter core print would revive October hike bets and pressure yen crosses, AUD and crypto.
- Micron and Korea. Results after the US close set the tone for Samsung, SK Hynix and the KOSPI, followed by South Korea’s September exports on Thursday.
- Yen intervention risk. MoF intervention data and further comments from Tokyo could push USD/JPY toward 156.00; a hawkish PCE would send it back to 157.50.
- Oil and Iran. SPR supply and Gulf export recovery weigh on crude, but a breakdown of talks or an OPEC+ surprise on Sunday could reverse it.
What Is Moving the Market
Bond rout and Fed hikes
The 30-year yield reached above 5.62% on Tuesday and the 10-year sits near 5.25%. Fed’s Williams said there is no urgency to hike again, though one more increase late in the year may be appropriate, leaving October odds near a toss-up.
Yen and quarter-end
Japanese exporters and investors sold foreign currency into half-year end while officials in Tokyo and Washington stressed cooperation on yen weakness. The BoJ’s next step is watched via Tankan and Tokyo CPI.
RBA, CPI and China
Headline CPI rose to 4.0% but softer core prints cut November hike odds. China’s PMIs rose above 50 and the RatingDog manufacturing index hit a five-month high, yet AUD stayed heavy.
Oil, sanctions and AI headlines
Reports that Trump backs easing Russia sanctions and a 40M-barrel SPR offer pressured crude, while Trump and tech leaders signed a voluntary AI accord. Reuters noted optimism over Anthropic’s IPO plans supporting US tech on Tuesday.
