British Pound holds steady following UK GDP; Yen draws support from intervention risks

• Persistent JPY selling supports GBP/JPY, keeping the cross steady on Thursday.
• GBP bulls stay cautious as a sharp USD rally outweighs largely positive UK economic releases.
• The prospect of intervention restrains further JPY weakness and limits gains in spot prices.

Support from continued Japanese Yen (JPY) selling helps GBP/JPY recover from a modest intraday decline to the 212.00 level in early European trade on Thursday. Even so, the cross stays within the range seen over the past week or so. Positive UK economic releases draw little response from spot prices, while the threat of intervention looms despite the supportive impact of JPY weakness.

The British Pound (GBP) finds no relief from the UK data as US Dollar (USD) strength dominates. In its first quarterly Gross Domestic Product (GDP) estimate, the Office for National Statistics (ONS) reported that the UK economy expanded by 0.7% over July to September. Annual growth reached 1.9%, a marked acceleration from  1.4% YoY in the preceding quarter. Separate September figures showed gains of 0.3% in Industrial Production and 0.7% in Manufacturing Production, with both readings exceeding market forecasts.

The JPY's underperformance persists even as expectations for additional Bank of Japan (BoJ) tightening strengthen, supported by the first increase in Japan's Corporate Goods Price Index (CGPI) in three months. Carry trades remain active because of the substantial interest rate gap between Japan and other major economies, including the UK, keeping the JPY under pressure. With the BoJ policy rate at 1.25% and the Bank of England (BoE) having lifted its base rate to 4.00%, the nominal differential stands at 275 basis points (bps). This maintains the GBP's yield advantage.

A warning against excessive FX volatility from Japan's top currency diplomat, Atsushi Mimura, has heightened intervention concerns, discouraging JPY bears from taking aggressive positions. These concerns constrain GBP/JPY, although the fundamental backdrop appears firmly favourable to bulls. Further buying momentum is nevertheless required to strengthen the case for more gains. Any corrective decline could still be regarded as a buying opportunity and is more likely to remain contained.
