USD/JPY was near 159.30–159.35 on August 27, 2026, as the Japanese yen stayed weak even after Bank of Japan Deputy Governor Ryozo Himino spoke about the risk of higher inflation. The market response was limited. The yen did not show a major rise after his remarks, and USD/JPY stayed close to the 160 level.
The main reason is simple. Himino gave a message that can be seen as cautious and more open to tighter policy, but he did not confirm that the Bank of Japan would raise its policy rate at the September meeting. At the same time, US inflation remains above the Federal Reserve’s 2 percent target, which keeps the US rate outlook important for the dollar.
Market data cited by Reuters put the chance of a BOJ rate rise at the September meeting at about 86 percent. Other market measures placed the probability close to 90 percent. These figures are market estimates, not guarantees.
The next major BOJ meeting is set for September 17–18, 2026. The policy rate is currently around 1.00 percent, while the Federal Reserve target range is 3.50–3.75 percent. This leaves a large rate gap in favor of the US dollar.
USD/JPY Data
The following table brings together the main figures that matter for the current market view.
| Measure | Latest figure | Why it matters |
|---|---|---|
| USD/JPY | ~159.29–159.35 | Shows continued yen weakness |
| Key level | 160.00 | Major psychological and policy-risk area |
| BOJ policy rate | 1.00% | Current Japanese short-term rate |
| Fed target range | 3.50–3.75% | Higher US rates support the dollar |
| Approx. rate gap | 2.50–2.75 percentage points | Supports dollar-yen carry |
| September BOJ hike pricing | ~86–90% | Shows strong market expectations |
| Japan July core CPI | 1.8% YoY | Below 2%, but close to target |
| Japan CPI excluding fresh food and energy | 1.9% YoY | Shows broader price pressure |
| Japan July wholesale inflation | 7.2% YoY | Strong upstream price pressure |
| US July PCE inflation | 3.7% YoY | Above the Fed’s 2% target |
| US July core PCE | 3.3% YoY | Shows persistent core price pressure |
| Next BOJ meeting | September 17–18 | Main near-term Japan policy event |
| Jackson Hole speech | August 28 | Key US policy signal |
The USD/JPY figure is a market level reported on August 27 and can change quickly. It should not be treated as a fixed price.
What Himino Said
Himino’s August 27 speech is important because it gives a direct view from a senior BOJ official. The BOJ’s official record shows that his speech covered Japan’s economy, inflation, foreign exchange rates, financial conditions, the Middle East conflict and demand linked to artificial intelligence.
His message was not a direct promise of a September rate rise. Instead, he stressed the need to assess economic and price conditions at each policy meeting. He also said that the BOJ should pay close attention to risks that inflation could move above the level it wants.
This matters because a central bank can give a more hawkish signal without making a firm policy commitment. In this case, the remarks support the view that the BOJ remains open to further rate increases. They do not prove that a rate rise will take place on September 17–18.
The distinction is important for a legally safe market assessment. A market probability is not the same as a policy decision. The BOJ can change its view after new data or new risks appear.
Japan Inflation
Japan’s inflation data give the BOJ a reason to remain alert.
Japan’s July core CPI rose 1.8 percent from a year earlier. This measure excludes fresh food. When both fresh food and energy were excluded, the rise was 1.9 percent. These figures are close to the BOJ’s 2 percent price stability target, although the exact policy meaning depends on the full set of economic data.
Another important figure is Japan’s July wholesale inflation rate of 7.2 percent. Wholesale prices can affect company costs and later consumer prices, although the pass-through from wholesale prices to consumer prices is not automatic.
This creates a difficult balance for the BOJ. Higher prices can support a case for tighter policy, but the source of those price increases also matters. A rise caused by strong domestic demand is different from a rise caused by energy costs, supply problems or currency effects.
Himino has previously explained this difference. The BOJ has noted that a weaker yen can raise import prices, while a rate rise can also affect economic activity. The central bank therefore has to judge whether price pressure is broad and persistent or mainly the result of temporary supply factors.
The BOJ Rate Path
The BOJ currently guides the uncollateralized overnight call rate to around 1.0 percent. Its official site also lists the complementary deposit facility rate at 1.0 percent and the basic loan rate at 1.25 percent.
The BOJ last raised its policy rate in June. It then kept the rate unchanged at the July 30–31 meeting. The next policy meeting is scheduled for September 17–18.
This creates a clear event risk for USD/JPY. If the BOJ raises rates in September and gives a firm signal that more rises could follow, the yen could receive additional support. If the BOJ does not raise rates, or if its message is less firm than the market expects, the yen could face renewed pressure.
Neither outcome should be treated as certain before the meeting.
The US Rate Picture
The US side remains just as important.
At its July 29 meeting, the Federal Reserve kept its target range at 3.50–3.75 percent. The decision passed by a 9–3 vote. Three members preferred a 25-basis-point rate increase. The Fed said inflation remained above its 2 percent goal and noted uncertainty linked in part to the Middle East conflict.
The difference between the Fed target range and the BOJ rate is therefore about 2.50–2.75 percentage points.
This rate gap helps explain why USD/JPY can remain high even when the BOJ sends a more hawkish message. Investors may still find dollar assets attractive because US short-term rates are much higher than Japanese rates.
This does not mean that the rate gap alone determines the exchange rate. Exchange rates also respond to bond yields, risk appetite, economic growth, inflation expectations, trade flows, central bank guidance and official policy action.
US Inflation
The July US Personal Consumption Expenditures price index rose 3.7 percent year over year. The market had expected about 3.6 percent. Core PCE, which excludes food and energy, rose 3.3 percent.
These figures remain above the Federal Reserve’s 2 percent target.
That creates a problem for traders who expect rapid US rate cuts. If inflation remains firm, the Fed may have less room to reduce rates quickly. A slower rate-cut path can support US yields and the dollar.
At the same time, inflation data alone cannot determine the Fed’s next decision. The central bank also considers employment, economic activity and the wider balance of risks.
The current data therefore create a two-sided policy picture. Japan has inflation pressure that can support a higher BOJ rate, while the United States also has inflation pressure that can support a higher-for-longer US rate path.
Why USD/JPY Stayed Near 159.30
The limited yen response to Himino’s remarks can be understood through the gap between expectation and new information.
The market already had a high probability assigned to a September BOJ rate rise. Reuters reported an estimate of about 86 percent, while another market measure cited by the Wall Street Journal placed the probability near 90 percent.
If traders already expect a policy move, a senior official’s general support for vigilance may not create a large new reason to buy yen.
The market may require a clearer signal. That could come from another BOJ official, new inflation data, wage data, the exchange rate itself, or the September policy statement.
This is why USD/JPY can remain near 159 even after comments that appear hawkish at first sight.
The 160 Level
The 160.00 area has special importance.
From a market view, it is a round number and a clear psychological level. From a policy view, a very weak yen can create concern because it can raise import costs and affect household prices.
A move above 160 would not by itself prove that the yen is entering a new long-term decline. It would, however, increase attention on Japanese policy signals.
The Japanese authorities have previously shown concern about excessive currency moves. The exact response to any future move cannot be known in advance. It could range from verbal comments to direct market action, or no action at all.
For that reason, 160 should be treated as a risk level, not as a guaranteed reversal point.
Key Market Levels
| USD/JPY area | Analytical meaning |
| Above 160.00 | Higher yen weakness risk and greater policy attention |
| 159.00–160.00 | Current major market zone |
| 158.00 | A move below this area could show stronger yen demand |
| 155–156 | A deeper move could suggest a larger shift in rate expectations |
| Below 150 | Would likely require a much larger change in the policy or yield outlook |
These levels are analytical reference points, not forecasts or guaranteed support and resistance levels.
What Could Support the Yen
A stronger yen could result if markets become more confident that the BOJ will raise rates and continue with further policy adjustment.
A second factor would be a softer US rate outlook. If US inflation falls, economic activity weakens, or Fed officials give a clearer signal for lower rates, the rate gap could narrow.
A third factor would be official Japanese action if authorities decide that currency moves have become excessive.
The strongest yen case would likely require several of these factors to appear at the same time. A single speech may not be enough.
What Could Support the Dollar
The dollar could remain firm if US inflation stays above target and the Fed keeps rates high for longer than markets expect.
A further rise in US Treasury yields could also support USD/JPY. Strong US economic data could have a similar effect if the data lead markets to reduce expectations for Fed rate cuts.
A weaker yen could also persist if the BOJ delays its next rate rise or gives a less hawkish message than markets expect.
Again, these are possible market paths, not certain outcomes.
Jackson Hole and the Fed
Another major event is the 2026 Jackson Hole Economic Policy Symposium.
The Federal Reserve’s official calendar lists a speech by Chairman Kevin Warsh for August 28 at the symposium in Moran, Wyoming.
The speech matters because markets can react strongly to any clear change in the Fed’s view of inflation, employment and future rates.
For USD/JPY, the key question is whether the speech creates a wider or narrower expected rate gap between the United States and Japan.
A more hawkish Fed message could support the dollar. A more dovish message could reduce that support. The actual market response will depend on what traders already expect before the speech.
September as the Main Test
September is likely to provide a more useful test of the current USD/JPY story.
The BOJ meeting is set for September 17–18. The market already assigns a high probability to a rate rise.
The decision itself will matter, but the guidance after the decision may matter just as much.
If the BOJ raises rates and signals that further adjustment remains possible, the yen could gain more support.
If the BOJ raises rates but gives a cautious message, the first yen reaction may not last.
If the BOJ does not raise rates, the market could need to reduce its strong September expectations. That could put fresh pressure on the yen.
The safest conclusion is that the September meeting is a major risk event, not a guaranteed turning point.
Overall Assessment
USD/JPY near 159.30 reflects a market with two strong forces on opposite sides.
Japan has a clear reason to consider tighter policy. Core inflation is near the 2 percent target, wholesale inflation is high, and a weak yen can add to import costs. Himino’s remarks show that the BOJ remains alert to upside price risks. The market also places a high probability on a September rate rise.
The United States, however, still has a much higher policy rate. The Fed target range is 3.50–3.75 percent, against a BOJ rate of 1.00 percent. US PCE inflation at 3.7 percent also remains well above the Fed’s 2 percent target.
That combination explains why the yen can remain weak even after a hawkish BOJ speech.
The most important near-term area is 159–160. A sustained move above 160 could increase market and policy attention. A clear move below 158 could suggest that expectations are shifting toward a stronger yen.
For a neutral assessment, neither direction should be treated as certain. The exchange rate can change quickly when central banks speak or when new inflation and employment data arrive.
The clearest conclusion from the current data is that USD/JPY is close to a major decision area. The BOJ is becoming more alert to inflation and currency risks, but the US rate advantage remains large. The next major clues should come from the Fed’s Jackson Hole message and, later, the BOJ’s September 17–18 policy decision.
