USDJPY Recovers to 158.53 as Strong US Jobs Data Meets a Hawkish BoJ & Tokyo’s Intervention Line — 156–159.50 Range Into December

USD/JPY rose 0.52% to 158.53 on Friday, recovering from a weekly low of 157.25 in early Tokyo trading. The October US jobs report pushed the pair back above 158 and up toward the top of the 156.00 to 159.00 range it has held since late September. The Bureau of Labor Statistics reported 165,000 new jobs against a consensus of 70,000, unemployment fell to 4.1%, and the dollar index rose 0.63% to 102.12, its biggest one-day gain since September 16. Thursday’s close was 157.70.

The week was a test of two forces, and neither side won. The yen strengthened on Wednesday and Thursday after minutes from the Bank of Japan’s September meeting pointed to more tightening, and Thursday’s 5.52% fall in the Nasdaq brought in safe-haven buying. USD/JPY lost 0.49% on Thursday. On Friday, Japanese wage data came in strong, and the yen still gave ground once US payrolls lifted Treasury yields and December Fed hike odds rose to 74.8%.

Our thesis is that USD/JPY is pinned in a range by forces of equal strength. The rate gap favours the dollar. The Fed funds target is 3.75% to 4.00%, while the Bank of Japan’s policy rate is 1.25%, leaving a gap of 262.5 basis points at the Fed’s midpoint. With the Fed priced for a December 9 hike, that gap is not about to close. Against that, Tokyo and Washington have shown they will defend the yen near 160. They carried out their first joint intervention in 28 years on July 31, when the pair traded near 164, and Japan spent a record ¥15.3993 trillion buying yen between July 30 and August 26. The Bank of Japan has also said it “will continue to raise” rates, and markets price a 68.4% chance of a hike on December 18.

Both central banks are likely to hike in December, so the differential won’t change much. That removes the main reason for USD/JPY to trend. What remains is a range: buyers enter on dips toward 156.50 because of the carry, and sellers enter near 159.00 because of the intervention risk. The pair has moved between 156.07 and 158.95 since mid-October, and Friday’s move from 157.25 to 158.53 kept it inside that band.

Our base case through the Fed decision on December 9 and the Bank of Japan meeting on December 18 is a range of 156.50 to 159.50, with a midpoint of 158.00. A break above the three-month high of 160.24 would put the intervention zone in play, and traders would expect Tokyo to act before the pair returns to the 163.86 high of July 29. A drop below 156.00 would need a Bank of Japan hike without a matching Fed move, or a deeper equity sell-off, and it would target the July 31 post-intervention low of 155.20, 2.1% below the current price.

The Week: 157.55 to 158.77, Down to 157.25, Back to 158.53

USD/JPY started the week near the middle of its range. It closed Friday, October 30, at 157.55, after the Bank of Japan’s hold at 1.25% and a week in which the pair rose 74 pips from 156.83 and reached 158.23 on October 28. The October close of 157.58 left the pair up for the month, even though the yen strengthened in the final three sessions.

The US midterm elections set the tone early. On Monday, November 2, the pair rose 0.25% to 157.95. On Tuesday, as voting got under way, it climbed 0.46% to 158.68 and reached an intraday high of 158.77, the week’s peak. Traders bought dollars on the view that a divided government would keep fiscal policy loose and Treasury yields high. The 200-day simple moving average at 158.66 capped that rally, and the pair could not hold above it.

Wednesday reversed the move. Once it became clear that Democrats had won both chambers of Congress, the dollar fell against most currencies. Lower oil prices and a lower chance of renewed US strikes on Iran pulled inflation expectations and Treasury yields down. USD/JPY fell to an intraday low of 157.40 and closed at 158.45, down 0.14%. Brent crude fell 8.7% that day, and lower oil helps Japan more than any other G7 economy because of its dependence on imported energy.

Thursday brought the yen’s best day of the week. Minutes from the Bank of Japan’s September meeting, when it raised rates from 1.00% to 1.25%, reinforced expectations of further tightening. The Nasdaq’s 5.52% fall and the S&P 500’s 4.36% decline brought in safe-haven buying, and Japanese government bonds rallied alongside the yen. USD/JPY fell 0.49% to close at 157.70, after trading as low as 157.54.

Friday started with more yen strength and ended with dollar gains. The pair fell to 157.25 early in the Tokyo session as Japan’s Nikkei dropped 6.7%, then rebounded above 158.00 as traders squared positions before the US jobs report. Japanese wage data came in strong and supported the yen briefly. After the payrolls release, USD/JPY rose to 158.53, 128 pips above the session low. For the week, the pair is up 98 pips, or 0.6%, from the October 30 close.

US Payrolls: 165,000 Jobs and a 74.8% December Hike

Friday’s jobs report gave the dollar its strongest support in weeks. Non-farm payrolls rose 165,000 in October, against a consensus of 70,000. September’s figure was revised up to 60,000 from 29,000, adding 31,000 jobs to the earlier estimate. The unemployment rate fell to 4.1% from 4.2%. Average hourly earnings rose 0.4% on the month, ahead of the 0.3% forecast. Professional and business services added 70,000 jobs.

The report put a December Fed hike back on the table. Futures now price a 74.8% chance that the Fed will raise rates on December 9. The Fed under Chair Kevin Warsh raised rates to 3.75% to 4.00% on September 16, the first increase since 2023, and held on October 28 by a 10–2 vote, with two members preferring another hike. US consumer prices rose 3.7% from a year earlier in September, and the PCE price index rose 3.6%, with core at 3.1%. Third-quarter GDP grew at an annualised 3.4%.

Treasury yields rose across the front end after the release. The two-year yield trades at 4.54% and the ten-year at 4.90%. Before the jobs report, yields had fallen during the AI-led equity sell-off as investors bought bonds for safety. The data reversed that and restored the yield advantage that has supported USD/JPY all year. USD/JPY tends to follow the US two-year yield more closely than any other pair, because the two-year captures Fed expectations directly.

The dollar index rose 0.63% to 102.12, on track for its biggest daily gain in seven weeks. The euro fell 0.55% to $1.1157, and sterling dropped 0.7% to $1.3356. The yen did better than both, falling 0.52% against the dollar, because safe-haven demand from the equity sell-off offset some of the rate pressure. In a risk-off market, the yen is the only major currency that can compete with the dollar for safe-haven flows.

For the forecast, the jobs data restores the floor under USD/JPY. A Fed priced to hike in December keeps the 262.5-basis-point gap intact, which means investors earn more than 2.6 percentage points a year for holding dollars instead of yen. That carry discourages traders from building large yen positions. The next test is Tuesday’s October consumer price index. A hot core reading would lock in the December hike and push the pair toward 159.00. A soft reading would lower the hike odds and send it back toward 157.00.

The Bank of Japan: 1.25%, an 8–1 Hold and a December Hike in View

The Bank of Japan has raised rates faster this year than at any time in three decades. It raised its policy rate from 0.75% to 1.00% on June 16 and from 1.00% to 1.25% on September 18, taking the rate to its highest level in 31 years. On October 30, it held at 1.25% by an 8–1 vote. Board member Takata Hajime dissented, proposing an increase to 1.50%. Governor Ueda and seven other members voted to hold.

The October statement was hawkish. The Bank of Japan said underlying consumer price inflation is at a level “generally consistent” with its 2% target, the first time it has made that judgment in 13 years. It said that because inflation is near target and financial conditions remain accommodative, “the Bank will continue to raise the policy interest rate and adjust the degree of monetary accommodation.” Governor Ueda said the policy phase is changing. The Bank raised its median forecast for core inflation in fiscal 2027 to 2.6%.

The data supports more tightening. Japan’s core CPI rose 2.1% in September, and underlying measures reached 2.4%. Factory confidence in the October Tankan survey was at its strongest level in years, although services sentiment weakened. Friday’s wage data came in strong, and the minutes of the September meeting, released on Thursday, showed members preparing for further increases. A survey of economists in October found 83% expected the next hike in December, up from 35% a month earlier.

Markets price a 68.4% chance of a hike on December 18, down from 77.3% before the October meeting. A hike would take the policy rate to 1.50%. Importantly, that would come nine days after the Fed’s December 9 decision. If both central banks raise rates by 25 basis points, the gap between them stays at 262.5 basis points. Only a Bank of Japan hike without a Fed hike would narrow it.

For the forecast, the Bank of Japan caps the upside without driving the pair lower. Its rate path makes yen shorts more expensive and gives the Ministry of Finance a credible policy backdrop for intervention. But at 1.25% or 1.50%, Japanese rates remain far below US rates. The carry trade still pays, and investors will keep borrowing yen to buy higher-yielding assets until the gap narrows to something closer to 150 to 200 basis points. That would take several more hikes in Japan or cuts in the US, and neither is likely before mid-2027.

Intervention: ¥15.3993 Trillion and the 160 Line

The Ministry of Finance has drawn its line near 160. On March 30, USD/JPY broke above 160 for the first time since July 2024, when Tokyo last intervened, and officials stepped up verbal warnings. The yen briefly recovered, but the Iran war, which began on February 28, pushed oil prices higher and the yen weaker. Japan intervened in April and May, after EUR/JPY reached 187.50, a level that also appears to have triggered later operations.

The largest intervention came in late July. With USD/JPY near 164 and the yen at its weakest level in roughly four decades, the Ministry of Finance began selling dollars and buying yen in New York trading on the night of July 30. On July 31, the US Treasury joined in, the first joint US-Japan yen-buying operation in 28 years. Finance Minister Satsuki Katayama confirmed the joint action on August 3 and said Japan “will not hesitate to conduct further joint intervention.” US officials made the same pledge.

The Ministry of Finance’s intervention data showed spending of ¥15.3993 trillion between July 30 and August 26, the largest monthly yen-buying operation on record. The Bank of Japan executes intervention on the ministry’s instructions, selling dollars from Japan’s foreign exchange reserves. Japan holds about $1 trillion in dollar reserves, and estimates put the cash and cash equivalents available for intervention at about $200 billion.

The intervention worked for a while. USD/JPY fell from near 164 to 155.20 on July 31, a three-month low for the dollar. The rate gap then reasserted itself, and the pair recovered to 159.10 by August 10 and 160.08 by August 29. A second wave of yen buying and US fiscal concerns pushed it below 156.70 in early September, and it reached a six-month low of 153.42 on September 14. Since late September, it has held between 156.00 and 159.00, and the three-month high is 160.24.

For the forecast, intervention sets the ceiling. Every move toward 160 since August has met verbal warnings or actual selling. The joint statement with Washington, which Katayama has called “very strong,” means the US Treasury is ready to take part again. That gives the threat more credibility than in any previous episode. Traders know that holding long USD/JPY positions above 159.50 risks a sudden loss of 4 to 5 yen in a single session, and that risk keeps buyers from pushing the pair through the 160 line.

Japan’s Fiscal Policy and the Takaichi Factor

Fiscal policy is the other domestic pressure on the yen. Prime Minister Sanae Takaichi’s government has pursued an expansionary fiscal policy, with higher spending to support households facing high energy prices and to boost defence and industrial investment. Markets have priced the risk that larger budget deficits will add to inflation and require more government bond issuance. When the dollar rose back to 160 in late August, caution over the government’s fiscal policy was one of the reasons, alongside Middle East inflation and the rate gap.

Japanese government bond yields have risen with the Bank of Japan’s hikes and the fiscal concerns. The Bank of Japan holds a large share of outstanding government bonds after a decade of quantitative easing, and its balance sheet stood at ¥625.03 trillion in September. It is gradually reducing its bond purchases, and Japan’s monetary base fell 13.6% from a year earlier in October. A shrinking central bank balance sheet combined with rising issuance puts upward pressure on long-term yields.

Higher Japanese yields help the yen only when they come from monetary policy. When yields rise because the Bank of Japan is tightening, the rate gap narrows and the yen strengthens. When they rise because investors worry about deficits, the yen can weaken, because foreign investors demand a risk premium for holding Japanese assets. Japan’s experience this year has included both: the June and September hikes supported the yen, while fiscal worries in August added to the selling.

The fiscal story also affects intervention. Japan finances yen buying by selling dollar assets, mostly US Treasuries, from its reserves. Large sales can push US yields higher, which widens the rate gap and works against the intervention’s goal. Washington has historically been cautious about joint operations for that reason, and the July joint operation was a sign of how seriously both governments viewed the yen’s weakness. If fiscal concerns weaken the yen again, Tokyo will be more reluctant to spend reserves it has already drawn down.

For the forecast, Takaichi’s fiscal policy is a weight on the yen that offsets part of the Bank of Japan’s hawkishness. It explains why the yen has not strengthened more despite two rate hikes and a record intervention. A budget that adds significantly to deficits in the coming months would push USD/JPY toward the top of the range. A credible commitment to fiscal discipline would remove one source of yen weakness and let the Bank of Japan’s hikes do more of the work.

Oil and the Yen: Why a US-Iran Deal Helps Japan

Japan imports nearly all of its energy, and the yen has traded as an oil-short currency since the Iran war began. When oil prices rise, Japan’s import bill grows, its trade balance worsens, and Japanese companies sell yen to buy dollars for energy purchases. That flow added to the yen’s weakness through the spring and summer, when Brent traded above $100 for long stretches and topped $120 in March.

The oil sell-off this week has helped the yen. Brent fell from above $110 on Monday to a $94.62 settlement on Wednesday, its lowest close since August 31, as traders priced a US-Iran deal after the midterms. Brent traded at $97.02 on Friday, down 12% to 16% for the week. Lower oil reduced the dollar demand from Japanese importers and lowered inflation expectations in the US, which pulled Treasury yields down. Both effects support the yen.

The link runs through Japan’s trade balance and terms of trade. A $10 drop in the oil price saves Japan billions of dollars a year in import costs, which reduces the structural selling of yen. It also lowers imported inflation, giving the Bank of Japan less reason to hike for energy-driven reasons. That second effect works against the yen, since fewer hikes would keep the rate gap wide. On balance, lower oil has historically been positive for the yen, because the trade-balance effect is larger.

A signed US-Iran agreement would be the most important positive yen catalyst outside of monetary policy. If the Strait of Hormuz reopens and Brent falls toward $85, Japan’s import bill would shrink significantly, and USD/JPY would lose one of its structural supports. A renewed US strike campaign during the lame-duck window between mid-November and mid-December would send oil back above $110 and push USD/JPY toward 160, testing Tokyo’s resolve again.

For the forecast, oil is a secondary driver but an important one. The pair’s three main drivers are the rate gap, intervention risk and oil. The first favours the dollar, the second caps it, and the third has turned slightly in the yen’s favour this week. If oil stays below $100, the pressure on the yen eases, and the pair is more likely to test 156.50 than 159.50. If oil rises above $110 again, the pair will move back toward the intervention zone.

Safe-Haven Flows: The AI Sell-Off and the Yen

The yen’s safe-haven role returned this week. On Thursday, the Nasdaq fell 5.52% into correction territory and the S&P 500 lost 4.36%, its worst day since April 2025, as fears of AI and data-center regulation spread after the Democratic sweep. On Friday, Japan’s Nikkei fell 6.7% and Korea’s KOSPI dropped 8.7%, triggering a circuit breaker. The yen and Japanese government bonds rallied as investors sought safety.

Safe-haven flows into the yen come from two sources. Japanese investors hold large amounts of foreign assets, and when global markets fall, they repatriate money and buy yen. Foreign investors who borrowed yen to fund higher-yielding positions, the carry trade, also buy yen to close those positions when markets turn volatile. Both flows strengthen the yen quickly. In August 2024, a carry-trade unwind sent USD/JPY down more than 10% in a few weeks.

This week, the dollar competed with the yen for safe-haven demand. Investors rotated into cash rather than out of the dollar, and the dollar index held its ground through the equity rout. One-week dollar deposit rates near 4% gave investors a return for holding dollar cash that the yen cannot match. USD/JPY fell only 0.49% on Thursday, much less than the scale of the equity sell-off would normally imply. The rate gap kept the carry trade intact.

The size of the carry trade is the hidden risk. With the rate gap at 262.5 basis points, many investors are borrowing yen to buy US Treasuries, equities and other assets. Those positions are profitable as long as USD/JPY stays stable or rises. A sudden yen rally, triggered by a deeper equity crash, a surprise Bank of Japan hike or intervention, could force those positions to close at once. That would push USD/JPY sharply lower, well beyond what fundamentals would justify.

For the forecast, safe-haven flows are the main downside risk. In the base case, the equity sell-off stabilizes, as Friday’s partial rebound suggests, and the yen’s safe-haven bid fades. In the bearish case, technology stocks keep falling, carry trades unwind, and USD/JPY breaks below 156.00 toward 155.20 or the September low of 153.42. The pair’s limited reaction to Thursday’s 5.52% Nasdaq drop shows the carry trade is resilient, but it has not been tested by a sustained rout.

The Rate Gap: 262.5 Basis Points and Why It Won’t Narrow Soon

The rate gap is the most important long-term driver of USD/JPY. The Fed funds target of 3.75% to 4.00% has a midpoint of 3.875%. The Bank of Japan’s policy rate is 1.25%. The gap of 262.5 basis points is narrower than it was a year ago, when the Bank of Japan’s rate was 0.50% and the Fed was cutting, but it is still large enough to make the carry trade profitable.

December will probably leave the gap unchanged. The Fed is priced at 74.8% to hike on December 9, which would move its midpoint to 4.125%. The Bank of Japan is priced at 68.4% to hike on December 18, which would move its rate to 1.50%. If both hike, the gap stays at 262.5 basis points. If only the Fed hikes, the gap widens to 287.5 basis points and USD/JPY would push toward 160. If only the Bank of Japan hikes, the gap narrows to 237.5 basis points, the yen’s best outcome.

The longer-term path favours the yen. The Fed’s hiking cycle is driven by energy inflation, which would ease if oil falls. Some forecasters expect the Fed to stop after one more hike and cut rates by 75 basis points by the end of 2027. The Bank of Japan has said it will keep raising rates, and markets expect its rate to reach 1.75% in 2027. If both forecasts come true, the gap would narrow to roughly 150 basis points by late 2027, enough to push USD/JPY well below 150.

Those changes are many months away. For the next six weeks, the gap will barely move, and the market will trade the expectations around each decision. The US two-year yield at 4.54% against Japan’s short-term rates sets the daily tone. A hot US CPI print on Tuesday would lift the two-year yield and push the pair higher. A Bank of Japan official signalling a December move would lift Japanese rates and push it lower.

For the forecast, the rate gap provides a floor, not a trend. A 262.5-basis-point gap pays investors to hold dollars, which makes large yen rallies difficult to sustain without a shock. It does not push the pair through the 160 intervention line, because the potential loss from intervention outweighs months of carry income. The gap explains why USD/JPY keeps returning to 158 after every dip. Intervention explains why it keeps falling back from 159.

The Technical Map: 158.66 Resistance, 157.25 Support

USD/JPY is trading just below its 200-day simple moving average at 158.66. That level capped the pair on Tuesday, when it reached 158.77 and closed at 158.68, and it is the first resistance. A daily close above 158.66 would turn the short-term trend higher and point to 159.00, the top of the range that has held since late September. The 50-day and 200-day exponential moving averages are both near 158.00, so Friday’s close above that area is constructive.

Above 159.00, the key levels are 159.50 and the three-month high of 160.24. The 160.00 handle is the line where the Ministry of Finance has acted or warned repeatedly this year. A break above 160.24 would put the pair at its highest level since late August and would put the intervention zone in play. Above that, the July 29 high of 163.86 is the 52-week peak and marks the level that triggered the joint US-Japan operation.

Support starts at 157.25, Friday’s weekly low, and 157.40, Wednesday’s intraday low. The 157.00 to 157.25 zone has held on every test this month. Below that, 156.50 and the late-October low of 156.07 mark the bottom of the current range. A daily close below 156.00 would break the range and target 155.20, the July 31 post-intervention low. Below 155.20, the September 14 low of 153.42 and the February 12 low of 152.64, the 52-week low, are the major supports.

The pattern since late September is a range with a slight upward bias. The pair has made lows at 156.07 and 157.25 and highs at 158.95 and 158.77, with no sustained break in either direction. Daily ranges have narrowed to 50 to 110 pips. That compression often comes before a breakout, and the December central bank meetings are the obvious catalysts. A move outside the 156.00 to 159.00 band in the next six weeks would likely be large.

From 158.53, the targets are close. 159.00 is 0.3% higher and 160.00 is 0.9% higher. 157.25 is 0.8% lower, 156.50 is 1.3% lower and 155.20 is 2.1% lower. The 163.86 July high would require a 3.4% gain. The asymmetry is clear: the upside to the intervention line is less than a yen and a half, while the downside to the range floor is two yen. In a market where Tokyo has shown it will act near 160, the limited upside makes long positions less attractive.

Event Risks: CPI, the Fed, the BoJ and Tokyo’s Warnings

Five events will drive USD/JPY over the next six weeks. The first is Tuesday’s October US consumer price index. After the strong jobs report, inflation data will decide whether the Fed hikes on December 9. A core reading at or above 0.3% on the month would lift the two-year yield and push the pair toward 159.00. A soft reading would bring the December odds back toward 50% and send it toward 157.00.

The second is the Fed decision on December 9. A hike to 4.00% to 4.25% would widen the gap temporarily until the Bank of Japan meets. The Fed’s statement and projections will show whether policymakers expect more increases in 2027. A hawkish projection would push USD/JPY toward 160 and test Tokyo’s resolve. A signal that the Fed is near the end of its cycle would let the pair fall back toward 157.00.

The third is the Bank of Japan decision on December 18. A hike to 1.50% is priced at 68.4%, so a move would not surprise the market. The guidance would matter more: a signal that the Bank will keep raising rates into 2027 would strengthen the yen. A hold would push the pair higher, especially if the Fed had hiked nine days earlier. Speeches by Bank of Japan board members in the coming weeks will shift those odds before the meeting.

The fourth is Tokyo’s rhetoric. The Ministry of Finance has a clear pattern of escalating warnings as USD/JPY approaches 160: from concern about “excessive volatility” to statements that it is watching markets “with a sense of urgency” to warnings that it will take “decisive action.” Each step has preceded intervention or a sharp yen rally. Any return to that language would signal the pair is near the ceiling.

The fifth is the equity market and oil. A deeper AI sell-off would trigger yen buying and carry-trade unwinds. A US-Iran deal would lower oil and help the yen, while a renewed US strike would raise oil and hurt it. These are background forces, but in a pair that has held a three-yen range for six weeks, they can provide the shock that triggers a breakout.

Scenario Map: 160.24 Upside, 156.50–159.50 Base, 155.20 Downside

Our forecast covers the period through the Fed decision on December 9 and the Bank of Japan meeting on December 18, with three scenarios.

The base case, at 55% probability, is a range of 156.50 to 159.50, with a midpoint of 158.00. In this scenario, US CPI comes in close to consensus, the Fed hikes on December 9, and the Bank of Japan follows on December 18, leaving the 262.5-basis-point gap unchanged. Oil trades between $90 and $105 as US-Iran talks continue. The equity sell-off stabilizes. The Ministry of Finance steps up verbal warnings whenever the pair approaches 159.50, and buyers return near 156.50.

The bullish case for USD/JPY, at 20% probability, is a break above the three-month high of 160.24. This would need a hot US CPI print that lifts December Fed hike odds above 90%, a Bank of Japan that holds in December, and oil back above $110 on renewed US strikes on Iran. The gap would widen to 287.5 basis points. In this scenario, the pair would test 160 and likely trigger intervention, which could send it back down by 4 to 5 yen in a single session.

The bearish case, at 25% probability, is a fall to 155.20, 2.1% below the current price. This would follow a soft US CPI print, a Fed that signals it is near the end of its cycle, and a Bank of Japan that hikes in December and guides toward more increases in 2027. A deeper equity sell-off would force carry-trade unwinds, and a signed US-Iran deal would send oil toward $85. A close below 155.20 would extend the decline toward 153.42.

From 158.53, the risk-reward favours selling rallies. The upside to 160.24 is 1.1%, and that level carries a high chance of intervention. The downside to 155.20 is 2.1%. The signals that will decide which scenario plays out, in order of importance, are Tuesday’s US CPI, the Fed’s December 9 decision and projections, Bank of Japan communications before December 18, the Ministry of Finance’s language on the yen, and the equity market’s direction.

Verdict: Neutral, Sell Rallies Into 159.00–159.50, Buy Dips Near 156.50

USD/JPY at 158.53 has rebounded 128 pips from Friday’s low of 157.25 after a strong US jobs report showed 165,000 new jobs against a 70,000 consensus and pushed December Fed hike odds to 74.8%. The pair is up 0.6% for the week and remains inside the 156.00 to 159.00 range it has held since late September. It sits just below the 200-day moving average at 158.66, which capped it on Tuesday.

The dollar’s case rests on the rate gap. With the Fed funds midpoint at 3.875% and the Bank of Japan at 1.25%, investors earn 262.5 basis points a year for holding dollars instead of yen. The Fed is priced to hike in December, and US inflation is running at 3.7%. Japan’s expansionary fiscal policy under Prime Minister Takaichi adds a risk premium to the yen. Those forces keep the pair from falling far below 157.

The yen’s case rests on policy and intervention. The Bank of Japan has raised rates twice this year to a 31-year high of 1.25%, says underlying inflation has reached its 2% target, and is priced at 68.4% to hike again on December 18. Japan spent a record ¥15.3993 trillion on intervention between July 30 and August 26, and the US Treasury joined in for the first time in 28 years. Both governments have pledged to act again. Lower oil and safe-haven demand from the AI sell-off add support.

Our call is neutral. We would sell rallies into 159.00 to 159.50, below the intervention zone, and buy dips near 156.50, within a base-case range of 156.50 to 159.50 and a midpoint target of 158.00. A daily close above 160.24 would put intervention risk at its highest and should be treated as a selling opportunity rather than a breakout. A daily close below 156.00 would break the range and target 155.20. Until either the Fed or the Bank of Japan surprises in December, the rate gap and Tokyo’s 160 line will keep USD/JPY inside the range.
