The Japanese Yen is maintaining a defensive position before the upcoming LDP leadership vote. Despite the Bank of Japan’s indications of continued policy tightening, the Japanese Yen’s movements in recent weeks reflect shifts in policy differentials between major global economies.
A potential risk for the Yen’s trajectory is the fiscal outlook. If the next administration leans toward more expansionary fiscal policies, it could affect how monetary policy is executed. Additionally, the Bank of Japan has been moderating its quantitative tightening efforts to minimise market disruptions, a strategy mirrored by the Bank of England.
Impact of Fiscal Measures
If fiscal measures exceed current expectations, while inflation continues above its target, further policy adjustments may be required, affecting real interest rates. This could lead to changes in the Yen’s value, although current trends indicate that USD/JPY purchases are mainly driving Yen sales. Even if current fiscal and monetary policies remain unchanged, it could be challenging to significantly increase Japanese Yen holdings from current levels, though the currency remains attractively valued.
The LDP leadership vote we saw in late September has now set a new tone for the market. The victory of a candidate favoring more government spending confirmed our fears about a more expansionary fiscal policy. Consequently, we watched the USD/JPY pair break through key resistance levels, surging past 160 as the market repriced Japan’s economic outlook.
This new fiscal direction creates a complicated environment for the Bank of Japan. Governor Ueda has been clear about further tightening, but the government’s push for a supplementary budget of nearly ¥20 trillion directly challenges the BoJ’s efforts to control inflation. The latest core CPI data for September showed inflation remains sticky at 2.9%, well above the central bank’s target.
Increased Currency Volatility
For derivative traders, this clash between fiscal and monetary policy points to increased currency volatility in the coming weeks. We are already seeing one-month implied volatility for USD/JPY options rise back above 11%, reflecting growing uncertainty. This suggests that holding positions through vanilla spot trading is becoming riskier, and options strategies should be considered for protection.
Given that many were already holding yen longs, as we noted last month, the focus should shift to managing risk. Buying USD/JPY call options or setting up call spreads offers a way to gain exposure to further yen weakness while limiting downside risk. This approach is prudent as the currency’s trajectory will be heavily influenced by the government’s final budget size and the BoJ’s response.
The core issue remains the path of real interest rates, which are now under pressure from the proposed fiscal impulse. We remember a similar situation in the UK back in 2022, when expansionary fiscal plans led to a sharp currency drop and bond market instability. If Japan’s real rates are suppressed by government spending, the yen is likely to face continued headwinds.
