United States August consumer price inflation report, the final inflation test before the Federal Reserve decision

Upcoming catalystiThe event that could move the exchange rate.

United States August Consumer Price Index, published by the Bureau of Labor Statistics. This is the final major inflation release before the Federal Reserve decision on 16 September 2026.

Event date and timeiWhen the event is expected. Shown in your own time zone, or in UTC if you switch the clock at the top of the page. If the exact hour is not confirmed, you only see the date.

Scheduled for 11 September 2026, 12:30 UTC.

Main currency pair affected

USD/JPY. It is highly sensitive to changes in United States and Japanese short-term bond yields. EUR/USD was rejected because the European Central Bank decision on 10 September creates a competing euro catalyst. GBP/USD was rejected because the Bank of England meets on 17 September.

Current priceiWhere the exchange rate stood when this write-up was made, and when that was.

156.246 as of 04 Sept 2026, 20:59 UTC, the closing rate of the week.

Expected directioniWhich way we expect the token price to go after the event. Positive means it rises, Negative means it falls, Mixed means it could go either way.

Negative. My base case is for USD/JPY to fall because underlying United States inflation is likely to continue cooling. That could reduce the probability of a Federal Reserve rate increase, while the Bank of Japan is expected to tighten policy.

Action before the eventiWhat we suggest you do before the event. Buy, Watch or Avoid.

Watch. Do not sell USD/JPY before the release. The bearish setup is strong, but the pair has already fallen about 380 pips in one week and is close to major support. Sell only after soft inflation confirms the thesis or after a weak rebound fails below resistance.

Why it mattersiHow the event reaches the price. Through demand, supply, how much the network is used, fees, or the rules the token trades under.

Softer core inflation means less pressure on the Federal Reserve to raise rates. That would lower expected United States short-term rates, pull down the United States yield advantage and weaken the dollar. At the same time, expectations for a Bank of Japan increase support Japanese yields and the yen. The full chain is softer United States inflation, lower Federal Reserve hike probability, narrower United States-Japan yield spreads, reduced demand for dollar carry trades, stronger yen, then lower USD/JPY.

Catalyst confidenceiHow sure we are that the event happens as described. Scored out of 100. Higher means more sure.

The release is confirmed on the official calendar. Catalyst confidence is 99%. My likely outcome is core inflation near 0.2% month on month and 2.4% year on year, but this forecast is less certain than the release schedule.

Price-reaction confidenceiHow sure we are that the pair moves the way we expect. Scored out of 100. Higher means more sure.

66%. The fundamental and technical biases point lower. Confidence is limited because the pair is already stretched, energy could lift headline inflation and both central banks meet during the following week.

Expected moveiHow far we think the price moves, and how long the move may last.

Our Expected Move: -70 to -140 pips, which is -0.45% to -0.90% from 156.246. Impact: High, because the upper end exceeds the pair's recent 110-pip average daily range. Estimated Duration: Within hours to 1 day. A very soft core reading could extend the move for 3 days as the Federal Reserve decision is repriced. On 14 July 2026, a softer inflation release caused an immediate fall of about 38 pips before later Federal Reserve comments reversed much of it. On 12 August 2026, an in-line release produced an initial fall of about 60 pips before the pair recovered. Those examples are not a clean statistical sample because other policy and intervention drivers were active.

What exactly is happeningiThe event itself in full. Who is involved, what changes, and the amounts and conditions that matter.

The Bureau of Labor Statistics will publish August consumer inflation. CPI measures changes in the prices households pay. Headline CPI includes food and energy. Core CPI removes those two volatile groups to show underlying pressure. In July, headline CPI rose 0.1% month on month and 3.4% year on year. Core CPI rose 0.2% month on month and 2.5% year on year. Forex traders care because the report lands five days before a finely balanced Federal Reserve decision.

Market expectationsiWhat most traders currently expect to happen. Bullish means they expect a rise, Bearish a fall, Neutral neither.

Bearish for USD/JPY. Early forecasts point to core CPI easing to about 2.4% year on year from 2.5%. A current inflation estimate points to headline CPI near 0.36% month on month, mainly because energy prices could rebound. I cannot confirm one broad survey median for every monthly and annual measure. Federal funds futures price roughly a 58% to 62% probability of a 0.25 percentage point Federal Reserve increase on 16 September. This means the decision is close enough for CPI to change the base case.

How much is already priced iniHow much of the expected outcome the exchange rate already reflects before the event happens.

Medium. USD/JPY fell about 380 pips, or 2.37%, during the week ending 4 September. Bank of Japan tightening is already heavily priced, while the Federal Reserve outcome remains close to a coin flip. Positioning also remains long-heavy in USD/JPY. The bearish theme is visible, but a soft CPI result is not fully reflected in Federal Reserve pricing.

Bullish scenarioiWhat would have to happen for the price to rise, and why the market would read it that way.

USD/JPY would likely rise if core CPI is at least 0.3% month on month and remains at 2.5% or higher year on year. A headline result around 0.4% or higher would reinforce the move. That combination could push Federal Reserve hike expectations above 75%, raise the two-year Treasury yield and trigger a rebound toward 158.00 or 159.00.

Neutral scenarioiThe outcome that simply meets expectations and moves the price very little.

Core CPI of 0.2% month on month and 2.4% to 2.5% year on year would broadly match expectations. USD/JPY could move sharply in both directions before returning toward 156.00 to 157.00. Traders would then wait for the Federal Reserve and Bank of Japan decisions.

Bearish scenarioiWhat would have to happen for the price to fall. A delay, a disappointment, or supply nobody expected.

Core CPI of 0.1% or less month on month, especially with a year-on-year reading of 2.3% or lower, would support a larger fall. Federal Reserve hike expectations could drop below 30%. A break below 155.00 would then expose 154.40 and 153.00.

Result needed for a big moveiWhat the outcome has to be for the pair to move a lot instead of a little.

A large move probably requires core CPI at or below 0.1% month on month, or at or above 0.3%. The downside reaction would be strongest if both headline and core inflation undershoot. The upside reaction would be strongest if core inflation reaches 0.3% or more and previous readings are revised higher.

Other currency pairs affected

EUR/USD could rise after soft United States inflation, but the European Central Bank decision one day earlier makes it a noisier expression. AUD/USD could rise because lower United States yields normally support risk-sensitive currencies, but global risk sentiment can interfere. USD/CHF could fall, although safe-haven demand for the Swiss franc can create a separate driver.

What else lands that dayiOther news and events on the same day that could push the price around, and whether they help this trade, bury it, or work against it.

The US consumer price index at 12:30 UTC is the event and 11 September 2026 holds little else against it. Real earnings arrives with it and the preliminary Michigan consumer survey follows at 14:00 UTC. The European Central Bank decided on 10 September, the day before, so the euro crosses have already repriced and are not competing for attention. I could not confirm a major scheduled Japanese release for 11 September itself. Two things about the day matter more than the calendar. The first is the hour: 12:30 UTC is 21:30 in Tokyo, so the Japanese cash market is shut and the yen leg of this move is made entirely by London and New York. The second is that the Bank of Japan meets on 17 and 18 September, the following week. Net effect: the dollar side is clean and the yen side is not being priced by the people who usually price it. What to expect on the day. Expect a full reaction in the US session and expect part of it to be re-tested when Tokyo opens on Monday, because Japanese participants meet the news two sessions late. Expect the follow-through to be capped as well: yen positioning from the middle of next week belongs to the Bank of Japan, not to this print, and traders will square up ahead of it rather than run a CPI trade into it.

Main risksiWhat could go wrong, and what would prove this call wrong.

High. Energy inflation could produce a stronger headline figure. The producer price report on 10 September could change expectations before CPI. USD/JPY is already close to oversold territory, increasing rebound risk. The European Central Bank, Federal Reserve, Bank of England and Bank of Japan decisions are clustered within eight days. A risk-off shock could support both the dollar and yen, making the net effect less clear. The initial CPI reaction could also fade within the United States session.

What the market may be missingiSomething we think investors have overlooked or read wrong.

The market may be placing too much weight on the stronger August payroll headline. Employment rose by 162,000, but core inflation is the more direct test of whether the Federal Reserve needs another increase. The Federal Reserve can tolerate solid employment more easily than renewed underlying inflation. A soft core result could therefore reverse a large part of the post-payroll rate repricing.

TrendiWhether the price is above or below its own 50-day and 200-day averages. Above both is an uptrend, below both is a downtrend.

Bearish. Over one week, USD/JPY fell from about 160.06 to 156.246, a decline of 380 pips or 2.37%. The week's high was 160.39 and the low was 155.28. Over one month, it fell about 144 pips or 0.91%, with a high of 160.39 and a low of 155.22. Over three months, it fell about 375 pips or 2.34%, with a high of 163.99 and a low of 155.22.

Market structureiThe shape of the chart. Rising highs and rising lows mean an uptrend, falling ones mean a downtrend, and neither means the price is stuck in a range.

Sellers control the short-term structure. Price rejected 160.40 and then produced lower highs and lower lows. A simple example is that the pair failed near 160.40, fell through 159.00 and then tested 155.30 twice. That is falling structure, not a stable range.

Support and resistanceiPrices where buyers have stepped in before, and prices where sellers have. A price often stalls or turns at these.

Support is at 155.30, which is 96 pips or 0.61% below 156.246. It was tested during both the 3 September and 4 September sessions. A close below it would confirm renewed selling. The next supports are 155.00, 126 pips or 0.81% lower, and 154.40, 186 pips or 1.19% lower. Resistance is at 156.75, 49 pips or 0.31% higher. Stronger resistance sits at 158.00, 174 pips or 1.11% higher, and 159.00, 274 pips or 1.75% higher.

VolumeiWhether trading is picking up or dying down. Rising volume behind a price move means more people agree with it.

I cannot confirm reliable daily regulated-exchange volume synchronized with the quoted spot price. Spot forex has no central exchange and no true global volume. Broker tick volume should not be treated as total market participation.

RSI and momentumiWhether the price has been rising or falling hard lately, and whether that push is getting stronger or running out.

The daily 14-period RSI is about 33.5. RSI measures how strongly price has risen or fallen over its last 14 periods. Momentum is weak and close to oversold, but oversold does not automatically mean price must rise. It means new short positions need careful entry timing.

Moving averagesiThe average price over the last 20, 50, 100 and 200 days. Trading above them is generally a healthy sign, below them a weak one.

A moving average is the average closing rate over a set number of days. The 20-day average is near 159.03 and the 50-day average is near 160.49. Both are above price and are turning into resistance. I cannot confirm synchronized values for the 100-day and 200-day averages. Independent daily chart readings confirm that price is below the major longer-term average cluster.

VolatilityiHow much this pair swings day to day right now, compared with how much it usually swings.

High. The 14-day average true range is about 110 pips, which is 0.70% of 156.246. Average true range measures how far the pair normally travels each day. One-week implied volatility is about 12.23% annualized. That implies an options-market one-week range near 265 pips, or 1.69%, but that week includes CPI and three major central bank decisions. Use smaller position size and allow more space than a routine 30-pip stop.

Breakout and breakdown levels

A decisive four-hour close above 156.80 would open 158.00, followed by 159.00. A decisive close below 155.30 would expose 155.00 and 154.40. A break below 155.00 would open a wider move toward 153.00.

Technical biasiWhat the chart alone suggests, ignoring the news. Rated Bullish, Neutral or Bearish.

Bearish. Price is below the 20-day and 50-day moving averages, the pair has formed lower highs and lower lows, and momentum remains weak. This agrees with the expected negative catalyst direction.

What would invalidate this biasiThe price level or chart change that would prove the technical read wrong.

A daily close above 159.00 would invalidate the bearish structure. I would then treat the fall toward 155.30 as a failed breakdown and expect a return toward 160.40. A hot CPI result combined with a widening United States-Japan two-year yield spread would strengthen that reversal signal.

Interest rate differential

The Federal Reserve target range is 3.50% to 3.75%. Its midpoint is 3.625%. The Bank of Japan target is around 1.00%. The midpoint gap is therefore 2.625 percentage points in favour of the United States dollar. A currency paying more interest is normally more attractive to hold, all else equal. The gap is expected to narrow if the Bank of Japan raises rates while the Federal Reserve stays unchanged.

Central bank biasiWhether the first currency's central bank is leaning toward higher rates, which is hawkish, or lower ones, which is dovish, compared with the second's.

The Federal Reserve is Hawkish in absolute terms but divided on immediate action. Federal Reserve guidance on 28 August supported a possible increase, while comments on 3 September said continued inflation improvement could justify holding. The Bank of Japan is Hawkish. It held at 1.00% on 31 July, but one member preferred a 1.25% rate and later comments on 2 September called for quicker normalization. The relative stance favours the yen, making the base-currency stance Dovish against the quote currency.

Expected rate cuts and hikes

Markets price roughly a 58% to 62% chance of a 0.25 percentage point Federal Reserve increase on 16 September. Bank of Japan market measures indicate roughly an 84% to 98% probability of a 0.25 percentage point increase on 18 September, depending on the instrument used. The Federal Reserve has more immediate repricing room because its decision is much less certain. CPI is likely to decide which side of that near-even split wins.

Bond yield differential

The United States two-year Treasury yield is about 4.37%, compared with roughly 1.84% for the Japanese two-year government bond. The spread is about 253 basis points in favour of the dollar. The United States 10-year yield is about 4.78%, compared with about 2.91% in Japan, a 187-basis-point dollar advantage. One basis point is one hundredth of a percentage point. The spreads remain large but have narrowed as Japanese yields and Bank of Japan expectations have risen.

Inflation trendiWhether price rises are speeding up, holding steady, or slowing down.

United States headline inflation slowed from 3.5% in June to 3.4% in July. Core inflation slowed from 2.6% to 2.5%. Japan's July headline inflation was 1.9%. Its measure excluding fresh food was 1.8%, while inflation excluding fresh food and energy was 1.9%. United States inflation remains higher, but its underlying trend is falling while Japan is close to its 2% target. This reduces the dollar's relative inflation advantage.

Economic growth trend

United States real GDP grew at a 1.5% annualized rate in the second quarter of 2026, down from 2.1% in the first quarter. Japan grew 0.3% quarter on quarter, equal to a 1.1% annualized pace, down from 2.1% annualized in the first quarter. Both economies slowed. The United States retains a small growth advantage, but the relative trend is stable rather than improving.

Risk sentimentiWhether investors are feeling brave or frightened. When they are frightened, money tends to move toward the dollar, the yen and the Swiss franc.

Neutral. The S&P 500 fell 0.38% on 4 September and the volatility index was near 14.5, which is low rather than a sign of market panic. Mild risk aversion supports the yen, but current conditions do not show a broad flight to safety.

Market positioning

Long-heavy in USD/JPY. The 1 September futures report showed leveraged funds net short 102,188 Japanese yen contracts, equal to about 24.8% of open interest. Because yen futures rise when the yen strengthens, a large yen short is broadly equivalent to a crowded long USD/JPY position. A soft CPI result could force traders to buy back yen quickly.

Carry trade attractiveness

Neutral. Holding dollars against yen earns a policy-rate advantage of about 2.625 percentage points per year. A carry trade earns the interest-rate difference but can lose money quickly if the exchange rate moves the wrong way. With daily range near 0.70%, high event volatility and a narrowing expected rate gap, the income is no longer enough to make the trade clearly attractive.

Core inflation pressure

Normal. United States core CPI is 2.5% year on year and falling. Japan's inflation measure excluding fresh food and energy is 1.9% and close to target. Underlying United States pressure remains higher, but two months of softer readings suggest it is becoming less persistent. A third soft result would support a Federal Reserve hold and a lower USD/JPY rate.
