National Bank of Canada (NBC) strategists Stéfane Marion and Kyle Dahms note that the piercing rebound in the Japanese yen (JPY) after USD/JPY broke above 160 was the result of intervention, not a change in fundamentals. Wide initial interest rate differentials and constrained near-term tightening by the Bank of Japan (BoJ) make the yen vulnerable. A more sustained recovery requires higher Japanese tiny interest rates, a broader weakening of the dollar, or a clearer signal of BoJ normalization.

The policy gap keeps the yen under pressure

“The yen recently returned to the center of currency markets as USD/JPY broke above 160, prompting stronger official warnings and yen buying intervention reported. The subsequent rise in the yen was sharp, but in our view the move is better understood as a time of intervention buying rather than a change in the underlying regime.”

“The key issue remains on the front end. Short-term interest rate differentials continue to favor the dollar, and the BoJ’s decision to leave interest rates unchanged at 0.75% at its April meeting did little to change this arithmetic.”

“As long as markets continue to see limited short-term monetary tightening from the BOJ and U.S. interest rates remain relatively high, the yen will likely struggle to generate sustained support from monetary policy alone.”

“The long end sends a more complicated signal. Japan’s 10-year bond yield has risen to levels last seen in the late 1990s, reflecting persistent inflation, gradual BoJ normalization risks and a higher term premium.”

“A more sustained recovery likely requires a narrower initial interest rate differential, a broader decline in the USD, or a clearer signal from the BoJ that it is prepared to tolerate higher interest rates. Until then, intervention can stabilize the yen, but it cannot reverse the trend cheaply.”
