Bitcoin rally stalls as Japan inflation and Iran war lift macro jitters
Bitcoin and ether slipped as traders reacted to renewed macro and geopolitical pressure.
Bitcoin (BTC) hovered around $77,594 and failed to reclaim the prior day’s high near $78,700. The broader uptrend that began in late March near $65,000 has stalled since Wednesday.
Ether (ETH) traded near $2,300, down about 0.8% since midnight UTC and underperforming BTC.
The main catalyst was fresh Japan inflation data. Japan’s Corporate Service Price Index (CSPI) rose 3.1% year-on-year in March (above expectations of 3.0%). Core inflation accelerated to 1.8% from 1.6%, while headline inflation edged up to 1.5% (still below the Bank of Japan’s 2% target). Although “core-core” inflation eased to 2.4%, markets increasingly expect the Bank of Japan to adopt a more hawkish tone.
At the same time, the Iran war is disrupting oil flows through the Strait of Hormuz, pushing energy costs higher. WTI crude futures rose over 40% to about $96 since late February. The Pentagon reportedly expects mine-clearing could take at least six months after the war ends.
Traders are now focused on the Bank of Japan’s upcoming meeting, where analysts suggest a warning could push rate expectations higher. A stronger JPY could be destabilizing for risk assets because the yen is often used to fund global carry trades—so a sharp yen rally could trigger an unwind.
Net effect: crypto weakness reflects a mix of rate-risk from Japan and inflation/oil shock risk from the Iran conflict, pressuring BTC-led momentum.

The article frames BTC’s momentum as stalling amid a “rates + oil shock” macro mix. Japan’s inflation prints (CSPI 3.1% YoY; core inflation 1.8%) increase odds the Bank of Japan may prepare for higher rates. That typically strengthens JPY and raises global risk-asset volatility because yen appreciation can unwind yen-funded carry trades.
At the same time, Iran-war shipping disruptions through the Strait of Hormuz lift WTI (up 40%+ since late February), feeding inflation concerns and complicating any Fed rate-cut path. Together, these forces usually tighten financial conditions and reduce appetite for high-beta assets like crypto.
In similar past regimes—when hawkish central-bank repricing coincided with energy-driven inflation worries—crypto often saw rallies fail at resistance and then trade range-bound or down until yields stabilize. For the short term, BTC likely remains pressured as traders wait for the next BoJ policy meeting and any further escalation in oil/geopolitical headlines. For the longer term, if the market later adapts to a calmer macro path (cooler inflation or less oil disruption), BTC’s late-March uptrend could resume; however, current signals tilt toward risk-off behavior rather than a clean continuation.
