Societe Generale's Kit Juckes has noted that recent political developments in the UK are causing only modest weakness in Sterling. According to FX Street, the impact on the currency has been limited so far, with expectations that the euro to pound exchange rate (EUR/GBP) could rise by one to two percentage points.

Juckes also forecasted that the British pound against the US dollar (GBP/USD) is likely to reach the 1.30 level this summer. This suggests a cautious but steady depreciation of Sterling relative to the dollar amid ongoing political uncertainties.

For Japanese investors, these FX movements are significant as fluctuations in GBP/USD and EUR/GBP can influence cross-currency trading strategies and risk management in global portfolios, especially given Japan's active participation in FX markets.
