British Pound consolidates vs Yen; bullish bias remains amid Japan's fiscal concerns

• GBP/JPY stalls its recent recovery from a multi-month low, though the downside seems cushioned.
• Japan’s fiscal concerns overshadow the recent US-Japan joint intervention and weigh on the JPY.
• The wide UK-Japan rate gap keeps the carry trade active and offers some support to spot prices.

The GBP/JPY cross struggles to capitalize on this week's solid rebound from the vicinity of mid-109.00s, or a four-month low, and edges lower during the Asian session on Thursday. Spot prices, however, lack follow-through selling and currently trade around the 212.30 region, down less than 0.10% for the day.

As investors look past the recent US-Japan joint intervention, worries about Japan's worsening fiscal condition undermine the Japanese Yen (JPY) and act as a tailwind for the GBP/JPY cross. Japan's ruling Liberal Democratic Party (LDP) backed a proposal to cut the food consumption tax from 8% to 1% for two years starting in April 2027. Adding to this, the Japanese government proposed roughly ¥600 billion a year in cash transfers targeted at low- and middle-income households as part of a relief package. However, the lack of a clear funding mechanism remains a key concern, which should cap any meaningful JPY gains.

Analysts at BNY Mellon describe a tone of “fiscal defiance” in Japan as Prime Minister Sanae Takaichi presses ahead with a two-year cut in the country’s food consumption tax “despite fiscal concerns and continued yen weakness.” They note that while “the measure may ease household pressure,” the “funding details remain the key credibility test” and that the initiative “cuts against the fiscal discipline needed to make coordinated currency intervention durable.”

BNY Mellon adds that “markets may support near-term relief, but not at any cost to Japan’s debt trajectory,” underscoring investor sensitivity to the longer-term fiscal implications. The bank points out that Japan’s ruling Liberal Democratic Party has now backed Takaichi’s plan “amid growing fiscal concerns,” with the proposal “approved unanimously by the party’s General Council” and expected to receive cabinet endorsement later. According to BNY Mellon, the tax cut would “take effect in April 2027 after parliamentary debate,” leaving markets to weigh short-term support for households against questions over funding and the sustainability of Japan’s broader policy mix.

Meanwhile, data released on Wednesday showed that real wages in Japan grew for the ​sixth consecutive month, by 1.6% in June. Adding to this, hawkish BoJ Minutes back the case for further policy tightening amid the upside risk to inflation. However, borrowing costs in Japan remain exceptionally low relative to other major economies, including the UK. The BoJ lifted the short-term policy rate in June to 1.00%, or the highest since 1995, while the Bank of England's (BoE) base rate is at 3.75%. This leaves a gap of around 275 basis points (bps), which, in turn, keeps the so-called JPY carry trade active and favors GBP/JPY bulls.

Traders now look to the release of the UK Constructive PMI for some impetus. Nevertheless, the aforementioned supportive fundamental backdrop suggests that the path of least resistance for the currency pair remains to the upside. Hence, any intraday corrective slide could be seen as a buying opportunity and is more likely to remain limited.
