USD/JPY Forecast: Is the Rally Over? Overbought RSI vs. Bullish Trend (2026)

Buckle up, USD/JPY traders! The pair is on a tear, but a key indicator is flashing red, suggesting this rally might be running on fumes. We're talking about the USD/JPY surging to levels unseen since mid-January, currently hovering around 156.54 – a nearly 0.65% jump and the third consecutive day of gains. This upward momentum is fueled by a potent combination: a relentlessly strong US Dollar and a persistently weak Japanese Yen. But here's where it gets controversial...

Technically speaking, the picture remains decidedly bullish. Since breaking free from a multi-month period of sideways movement in early October, USD/JPY has consistently printed higher highs and higher lows. This is a classic sign of strong directional momentum, indicating buyers are firmly in control. Think of it like a staircase, each step higher than the last, showing a clear path upwards.

The initial breakout above the psychologically significant 150.00 level was ignited by speculation that Sanae Takaichi was poised to become Japan’s next Prime Minister. Markets interpreted this as a green light for potential fiscal expansion, essentially meaning the government would spend more money. Why did this weaken the Yen? Because increased government spending can sometimes lead to inflation, which can devalue a currency. And this is the part most people miss... When Takaichi officially took office and confirmed a large-scale fiscal stimulus plan, those expectations were cemented, keeping the Yen under relentless downward pressure.

Looking at the daily chart, the price action is comfortably positioned above all major Simple Moving Averages (21-SMA, 50-SMA, 100-SMA). For those new to trading, these SMAs act like dynamic support levels. The fact that the price is above them confirms buyer dominance and reinforces the existing bullish trend. Imagine the SMAs as a safety net; as long as the price stays above them, the uptrend is likely to continue.

Now, let's talk about potential targets and obstacles. On the upside, the January 23 swing high at 156.75 is the immediate resistance level to watch. A decisive break above this point could pave the way for a retest of the year-to-date high at 158.88, which was marked on January 10. These levels act like ceilings; breaking through them requires significant buying pressure.

Conversely, on the downside, 155.00 serves as the initial support level, followed by the 21-day SMA at 153.86. These levels act like floors, potentially halting any downward movement. While Japanese authorities have issued verbal warnings about the Yen's excessive weakness – essentially jawboning the market – concrete intervention (actually buying Yen to prop up its value) remains absent. This makes a deeper corrective pullback possible, but it's not the most likely scenario in the near term. Think of it like this: the government is warning the market, but without taking action, their words might not carry much weight.

But here’s the kicker: momentum indicators are flashing a warning sign. The Relative Strength Index (RSI) is currently near 72, firmly entrenched in overbought territory. This means the price has risen too far, too fast, and a correction could be imminent. While no clear bearish divergence (where the price makes a higher high, but the RSI makes a lower high, signaling weakening momentum) has formed yet, the overbought RSI could slow down the bullish momentum or trigger a period of consolidation. It's like a car overheating; it might still run, but it's at risk of breaking down.

US Dollar Strength Today:

Looking at the broader currency market, the US Dollar is showing significant strength across the board. As you can see in the table below, the USD has gained against all major currencies, with the most significant gains against the New Zealand Dollar.

The heat map provides a visual representation of these percentage changes, making it easy to see the relative strength of each currency pair. For example, looking at the USD/JPY box, you can see the percentage change reflecting the US Dollar as the base currency and the Japanese Yen as the quote currency.
