• GBP/JPY is rising as pre-election concerns the ruling LDP party could lose weakens the Yen. 
• A change of government or weaker ruling coalition could impact the BoJ’s decision making with consequences for the currency. 
• The Bank of England’s relatively more hawkish stance on interest rates is a further backwind for GBP/JPY. 

The GBP/JPY is trading over 1.0% higher on Wednesday in the 198.30s. A combination of political instability in Japan and shifting economic forecasts, coupled with differing monetary policy outlooks between the Bank of Japan (BoJ) and the Bank of England (BoE), are key elements shaping market sentiment and trading behavior.

The Japanese Yen (JPY) has been under considerable selling pressure due to domestic political uncertainty in Japan. Recent polls suggest that the ruling Liberal Democratic Party (LDP) may lose its majority in the upcoming general election. A potential leadership shift or the need for a coalition could complicate the government's policy-making, including monetary policy conducted by the Bank of Japan. Political instability often creates risk aversion, leading to a weakening of the affected currency, which, in this case, places downward pressure on the Yen. 

The International Monetary Fund's (IMF) downgrade of Japan's economic growth forecast to 0.3% for this year, down from a previous 0.7%, further exacerbates this pressure. A weaker economic outlook generally reduces demand for a currency, contributing to a decline in its value. In the near term the weak growth reflected in these revisions are contributing to downward momentum for the Yen, which can lead to an increase in the GBP/JPY exchange rate.
