National Bank of Canada (NBC) strategists Stéfane Marion and Kyle Dahms note that the Japanese Yen’s (JPY) sharp rebound after USD/JPY breached 160 was driven by intervention rather than a shift in fundamentals. Wide front-end rate differentials and limited near-term Bank of Japan (BoJ) tightening keep JPY vulnerable. A more durable recovery is seen requiring higher Japanese short rates, broader Dollar weakness or a clearer BoJ normalization signal.
Policy gap keeps yen under pressure
“The yen was back at the centre of FX markets recently as USD/JPY moved through 160, prompting stronger official warnings and reported yen-buying intervention. The subsequent rally in JPY was sharp, but in our view the move is better understood as intervention buying time rather than changing the underlying regime.”
“The key issue remains the front end. Short-term rate differentials continue to favour the dollar, and the BoJ’s decision to leave rates unchanged at 0.75% in the April meeting did little to alter that arithmetic.”
“As long as markets see limited near-term BoJ tightening and U.S. rates remain comparatively high, the yen is likely to struggle to generate sustained support from monetary policy alone.”
“The long end sends a more complicated signal. Japan’s 10-year yield has risen to levels last seen in the late 1990s, reflecting sticky inflation, gradual BoJ normalization risk and a larger term premium.”
“A more durable recovery likely requires a narrower front-end rate differential, a broader USD decline, or a clearer BoJ signal that it is prepared to tolerate higher rates. Until then, intervention can stabilize the yen, but it cannot cheaply reverse the trend.”
