The USD/JPY exchange rate starts the week on a weaker footing, impacted by several negative influences. The Japanese Yen (JPY) gains strength due to expectations of a Bank of Japan rate hike and a global risk-off sentiment, while the US Dollar (USD) weakens amid a US credit rating downgrade and dovish Federal Reserve forecasts.
The pair dropped to around the 144.80 level, a one-week low, during the Asian session. Market conditions suggest a continued downward trend following last Monday’s nearly six-week high, with the JPY supported by potential future interest rate hikes by the Bank of Japan.
Us Credit Rating Downgrade
Moody’s recently downgraded the US credit rating from “Aaa” to “Aa1” due to growing national debt, prompting a shift to safer assets like the JPY. The USD faces downward pressure as the Federal Reserve might cut rates amid reduced inflation rates and expected economic slowdown in the US.
There is no key US economic data expected on Monday; the USD’s movement might depend on Federal Reserve communications and global market sentiment. Differences in BoJ and Fed policies suggest a negative near-term outlook, though any short-term USD/JPY upticks may offer selling opportunities.
In simpler terms, the Japanese yen has been gaining appeal lately, not because of sudden strength in Japan’s economy, but more from the perceived stumbles on the US side. With Moody’s cutting the US credit rating, attention shifted quickly to safer alternatives. Investors reacted by seeking assets like the yen, which tends to fare well during those jittery patches in the market.
Meanwhile, the Federal Reserve is leaning in a direction that suggests they’re closer to pausing, or even lowering interest rates. Inflation in the US has been slowing, and there are more worries about how strong the economy truly is—especially with labour markets showing subtle signs of cooling. Lower interest rates usually mean a weaker dollar, because returns on dollar-based assets may not look quite as inviting.
Policy Divergence
At the same time, the Bank of Japan is showing signs of finally adjusting its long-standing ultra-loose stance. Even though policy changes have come very slowly in Japan, expectations for at least a mild rate increase are building. That contrast—Japan possibly becoming tighter, while the US becomes looser—sets the tone for pressure to persist on this pair.
The fall below 145 was more than just a round-number break. We saw a clear rejection after last week’s peak, and barring any sudden surprises out of Washington or Tokyo, rallies could be opportunities to re-engage the downtrend. Earlier highs, especially above 147, held firmly, and now that the market’s bias is turning, a re-test of 144 or even lower seems reasonable.
We should also remember what isn’t on the calendar—no major US data releases at the beginning of the week means the pair is more vulnerable to broader sentiment shifts and any stray remarks from Fed speakers. Markets are highly sensitive to tone now. Comments viewed as a bit soft or less committed to tightening tend to play directly against the dollar.
For short-term positioning, this suggests leaning towards favouring a stronger yen, or at least treating any recovery in the dollar as temporary. That’s particularly true if reactions to Fed communication stay muted or tilt dovish. Implied volatility remains reasonably tame, but as BoJ speculation gains pace, the chances of sharper moves—especially around rate-sensitive headlines—increase.
Risk appetite globally continues to take a hit, and that’s a supportive backdrop for the yen, considering its traditional role in stress scenarios. Moves in equity indices, especially in the US and Asia, deserve close watch. If the tone stays cautious, flows into JPY could accelerate.
All told, the underlying mood remains broadly supportive for continued dollar weakness versus the yen, especially as positioning adjusts. Policy divergence is becoming clearer, and short-term traders should continue to focus on key levels like 144 and 143.60, watching for price action at those points before shifting bias.
