At a Glance

Lead — The desk believes that core inflation indicators from the Bank of Japan (BoJ) will play a crucial role in shaping monetary policy discussions in the coming months. Per the full note source, these indicators, which exclude transitory factors, are essential for accurately assessing Japan's underlying inflation rate. With upcoming GDP data and trade balances, traders should be attuned to how these core measures might influence the BoJ's stance. The consensus target for USD/JPY remains at 1.075, with a range between 1.04 and 1.12.

Full Analysis

What the desk is arguing

The desk posits that the core inflation indicators released by the Bank of Japan will be pivotal in determining future monetary policy adjustments. Per the full note source, these indicators strip out temporary influences such as tax changes and subsidies, providing a clearer picture of inflation trends. This clarity is particularly relevant as the BoJ navigates its path amid global inflationary pressures.

The BoJ's focus on core indicators, including the trimmed mean and weighted median, suggests a commitment to understanding the true inflation landscape. Recent data releases have shown persistent inflationary pressures, which could compel the BoJ to reconsider its ultra-loose monetary policy sooner than anticipated. For instance, the exclusion of institutional factors from the CPI data allows for a more accurate assessment of inflation trends, crucial for market participants.

Where it sits in our coverage

Our consensus target for USD/JPY is set at 1.075, with a range from 1.04 to 1.12. Specific firm targets include: - jpmorgan: 1.10 (Mar26) - bofa: 1.04 (Mar26)

This view aligns closely with jpmorgan, which anticipates a stronger USD/JPY based on potential shifts in the BoJ's policy stance. However, it diverges from bofa, which remains cautious about the upside potential for USD/JPY given the current economic landscape.

How other firms see it

Firms like jpmorgan and citi are aligned in their bullish outlook for USD/JPY, driven by expectations of rising inflation and potential policy shifts from the BoJ. Conversely, bofa and deutsche express more caution, suggesting that the current inflation metrics may not be sufficient to prompt a significant policy change.

Traders should keep an eye on the USD/JPY pair as it reflects the broader implications of the BoJ's inflation indicators. Additionally, the upcoming GDP growth rate and balance of trade data will further illuminate the economic context in which these inflation measures are situated.

What the calendar says

With the GDP Growth Rate and Balance of Trade data scheduled for May 19, traders should be prepared for potential volatility in USD/JPY as these indicators may influence market perceptions of the BoJ's policy trajectory.

What changed vs prior statement

  • 02Core CPI data released two business days after official CPI, excluding institutional factors like tax changes.
  • 03New emphasis on distribution-based inflation measures (trimmed mean, weighted median, mode) for underlying inflation assessment.

Japan’s inflation slowed unexpectedly, but BoJ still likely to hike rates in June

Lead — The desk anticipates a Bank of Japan (BoJ) rate hike in June despite an unexpected easing in Japan's consumer price index in April. Per the full note from **ing**, the moderation in CPI is largely attributed to government measures and the high base effect from last year's food prices, which contributed to this slowdown. However, core inflation remains steady, with ongoing growth supporting the view of tighter monetary policy. As the BoJ moves towards normalization, market participants should prepare for potential volatility in the JPY and consider implications for cross-currency flows.
