Bitcoin's push higher hit the brakes on Friday as fresh inflation data from Japan added to market anxiety sparked by the Iran conflict — a one-two punch weighing on risk assets, including crypto.
Market moves
- Bitcoin (BTC) was stuck near $77,800 in early Asian hours, failing to reclaim Thursday’s $78,700 high, according to CoinDesk. The broader bullish run that began in late March around $65,000 has shown signs of stalling since midweek.
- Ether (ETH) lagged, trading near $2,300 and down about 0.8% since midnight UTC, underperforming Bitcoin’s roughly 0.6% dip.
Why Japan matters for crypto
Japan’s latest inflation prints added a layer of macro uncertainty. The Corporate Service Price Index (CSPI) rose 3.1% year‑on‑year in March (vs. a 3.0% forecast), and core inflation climbed to 1.8% from 1.6% — the first acceleration in five months. Headline inflation ticked up to 1.5% from 1.3%, still shy of the Bank of Japan’s 2% target, while core‑core inflation eased to 2.4%, its lowest since October 2024.
These readings matter because rising inflation — partly driven by higher energy costs from disruptions around the Strait of Hormuz — could nudge the BOJ toward a firmer policy stance. InvestingLive analysts expect the central bank to hold rates next week but to signal that hikes are increasingly likely, putting June “in play” if war‑related inflation risks persist.
FX and risk sentiment link
A shift toward tighter BOJ policy would likely strengthen the Japanese yen. Because the yen has historically been a funding currency for carry trades (borrow cheap yen to buy higher‑yielding or risk assets), a sudden yen rally could force unwinds of those trades and spark broader risk aversion — a negative for crypto and other risk assets. Speculative positions in the yen are currently bearish, according to recent CFTC data, so the potential for a sharp reversal is real.
Geopolitics: Strait of Hormuz and oil shocks
Geopolitical developments are the other headline driver. Axios reports Iran has deployed additional naval mines in the Strait of Hormuz, a chokepoint responsible for about 20% of global seaborne oil flows. Shipping through the strait has dropped sharply since the fighting intensified. WTI crude futures have jumped more than 40% to around $96 since the Iran conflict escalated in late February — a direct pressure point for importers like Japan and a contributor to the inflation uptick.
Wider implications
The Pentagon has warned lawmakers it would take at least six months to clear mines from the Strait and that clearance operations would only begin after the conflict ends. The U.S. defense note also warned inflation could remain elevated this year, potentially complicating the Fed’s path to cutting rates.
Bottom line for crypto
Crypto’s recent rally is vulnerable to macro shocks. Geopolitical disruption that lifts energy prices and forces tighter policy expectations in major economies can reverberate through FX markets, trigger de‑risking, and sap demand for speculative assets — keeping Bitcoin and Ether on edge until volatility subsides.
