OCBC Bank’s report examines the ongoing weakness of the JPY amid fiscal uncertainty before Japan’s election on 8 February. JGB yields show contrasting behaviour, indicating differing interpretations regarding Japan’s fiscal outlook.
Verbal intervention risks may rise due to the election, affecting the JPY. Concerns about fiscal policies could limit USDJPY movement both before and after the vote.
Contrasting Market Views
Fiscal worries usually weaken the JPY and increase long-end JGB yields. The quiet JGB market vs. a weaker JPY suggests differing views between bond and FX markets on the fiscal direction post-election.
A majority win could allow PM Takaichi to strengthen his mandate for fiscal stimulus, which might pressure the JPY. However, a clear LDP majority might stabilise the JPY by reducing the need for looser fiscal or monetary measures.
With the Japanese election just days away on February 8th, we are seeing significant pressure on the yen due to uncertainty about future government spending. This political risk is the main focus for currency traders this week. The outcome will likely set the tone for the yen’s direction in the near term.
The fundamental weakness is clear when looking at the interest rate gap, with the Bank of Japan’s policy rate at -0.1% while the U.S. Federal Reserve’s rate is over 4%. This wide differential is the primary reason the USD/JPY exchange rate has been trading above 162 recently. The election is simply adding another layer of uncertainty to an already weak currency.
Implied Volatility and Government Intervention
Reflecting this tension, we see that one-week implied volatility in the USD/JPY options market has spiked to over 15%, far above its recent average of 9%. This shows traders are paying a premium to protect against, or profit from, a sharp move in the currency following the election results. Such a spike signals that a significant price swing is expected.
At these elevated exchange rates, the risk of the government stepping in to buy yen is very real. We saw authorities intervene directly in the market back in the autumn of 2024 when the rate first pushed past the 160 level. This history of intervention should make traders cautious about how much further USD/JPY can rise before and immediately after the vote.
A decisive victory for the ruling LDP coalition would likely empower the Prime Minister to pursue fiscal stimulus, a policy that would probably lead to more yen weakness. Conversely, a less clear-cut majority might force a more moderate stance. This could reduce the need for aggressive spending and bring some stability back to the currency.
It is notable that while the yen is struggling, the Japanese government bond market has been relatively stable. This suggests bond investors may have a different, less concerned view on the country’s fiscal path compared to currency traders. If we begin to see bond yields rise, it would confirm that bearish sentiment on the yen is becoming more widespread.
