Citi projects the USD/JPY exchange rate will remain confined to a narrow range of ¥158 to ¥160 per dollar despite developments that would ordinarily signal a shift in the long-term trend. In a research note, the bank said the required condition for a reversal from an uptrend in USD/JPY to a downtrend - namely a contraction in the interest rate spread - has already occurred.
However, Citi noted that this potential turning point has been prevented over recent months by downward pressure on the yen driven by a risk-on environment. Specifically, historically strong gains in Japanese equities have weighed on the currency, offsetting the narrowing U.S.-Japan rate differential.
The bank cautioned that ongoing strength in Japanese stock markets could continue to impede a recovery in the yen, even in a scenario where an Iran ceasefire leads to a halt in rising oil prices. Citi also stated it expects the Bank of Japan to keep its policy rate unchanged next week, a view that feeds into its outlook for limited near-term movement in the currency pair.
Citi outlined a clear intervention threshold: should the USD/JPY climb above ¥160 per dollar, authorities would likely step in to buy yen. Such intervention, the bank said, would probably force the pair back down to around ¥155 per dollar, which Citi views as the likely maximum near-term downside for the exchange rate.
In summary, while the interest rate spread between the U.S. and Japan has narrowed enough to satisfy a condition for a longer-term USD/JPY trend reversal, the immediate path for the yen remains constrained by strong equity performance and the prospect of intervention above ¥160. The bank's expectation that the Bank of Japan will hold the policy rate steady next week further supports a view of limited directional movement within the ¥158-¥160 corridor.
