<p>Crypto prices held firm on Sept. 18 after the Bank of Japan raised its policy rate by 25 basis points to 1.25%, the highest level in 31 years. Bitcoin traded above $77,000 after the decision, while Ethereum and Solana also remained higher as markets absorbed a move that had been widely expected before the BOJ meeting.</p>
<p>The reaction matters because higher Japanese rates can make yen-funded carry trades less attractive and increase pressure on leveraged positions across global markets. However, the yen weakened sharply rather than strengthening after the&nbsp;<a href="https://www.thecoinrepublic.com/2025/12/20/bitcoin-price-still-threatened-despite-fed-and-boj-delivering-short-term-relief/" rel="noopener noreferrer nofollow">BOJ&nbsp;</a>decision, easing immediate fears of a disorderly carry-trade unwind, while Bitcoin futures open interest remained near $51.6 billion.</p>
<h2 id="h-crypto-prices-hold-firm-after-boj-decision" class="wp-block-heading"><strong>Crypto Prices Hold Firm After BOJ Decision</strong></h2>
<p>Binance market data showed <a href="https://www.thecoinrepublic.com/2026/04/24/bitcoin-price-eyes-86k-as-btc-etf-inflows-rake-in-another-223m/" rel="noopener noreferrer nofollow">Bitcoin</a> trading near $77,585 early Friday. The asset gained about 1.6% over 24 hours. Its intraday range stretched from roughly $75,946 to $77,622.</p>
<p>CoinMarketCap data showed Ethereum near $2,443, up about 0.7% over 24 hours. Solana traded near $101.63 after gaining about 3.1% during the same period. Those moves indicated crypto prices avoided an immediate broad selloff after the BOJ decision.</p>
<p>The resilience contrasted with fears surrounding tighter Japanese policy. Japan’s low borrowing costs have historically supported yen-funded carry trades. Investors borrow Japanese yen, then deploy capital into higher-yielding or riskier assets.</p>
<p>However, Friday’s decision had been widely anticipated before the meeting. That reduced the probability of a sudden repricing based solely on the increase in the headline rate.</p>

<p>Reuters reported that the Bank of Japan raised rates by 25 basis points. The board lifted its policy rate from 1.00% to 1.25% through a 7-2 vote.</p>

<p>Board members Toichiro Asada and Ayano Sato voted against the increase. The new rate marked Japan’s highest policy level in 31 years. The move also followed the previous increase in June.</p>
<p>The Bank of Japan said underlying inflation had been approaching its 2% objective. Policymakers also cited broadening price pressures across Japan’s economy. Reuters reported that officials remained prepared to raise rates further if their outlook materialized.</p>
<p>The Bank of Japan’s published calendar listed the Sept. 17-18 meeting. It also scheduled the meeting’s Summary of Opinions for Oct. 1. That release could provide more detail on officials’ views about future tightening.</p>
<h2 id="h-japanese-yen-weakens-despite-boj-rate-hike" class="wp-block-heading"><strong>Japanese Yen Weakens Despite BOJ Rate Hike</strong></h2>
<p>The Japanese yen weakened after the decision rather than strengthening. Reuters data showed the currency falling as much as 0.8% against the dollar. The exchange rate reached 157.145 yen per dollar, its weakest level since Sept. 3.</p>
<p>The reaction reduced immediate fears of a disorderly yen carry-trade unwind. A stronger Japanese yen can increase repayment costs for investors using yen-funded leverage. Friday’s weaker currency reduced that pressure during the initial market response.</p>
<p>National Australia Bank strategist Ray Attrill said the decision underwhelmed market expectations. He pointed to the two dissenting votes and limited guidance about another near-term increase.</p>
<p>SMBC chief foreign-exchange strategist Hirofumi Suzuki also focused on the dissent. He said the split vote tempered expectations for faster tightening. Those reactions helped explain why the currency weakened despite higher Japanese rates.</p>
<h2 id="h-crypto-prices-face-leverage-test-as-futures-activity-stays-high" class="wp-block-heading"><strong>Crypto Prices Face Leverage Test as Futures Activity Stays High</strong></h2>
<p>CoinGlass data showed Bitcoin futures open interest near $51.6 billion on Friday. Twenty-four-hour futures volume stood near $50.3 billion. Bitcoin traded at around $77,250 on the derivatives platform at the time the data was captured.</p>

<p>Those figures showed leveraged exposure remained elevated as crypto prices absorbed the policy decision. They did not show an immediate collapse in futures participation following the BOJ announcement.</p>
<p>Open interest measures outstanding derivatives positions rather than directional conviction. High open interest can amplify volatility when sharp price moves force traders to reduce leveraged positions.</p>
<p>The yen, therefore, remained an important cross-asset indicator for crypto traders. A renewed currency rally could raise carry-trade concerns again. Persistent yen weakness would reduce that immediate funding pressure.</p>
<p>Friday’s intraday range also defined the nearest observable market levels. Binance recorded a 24-hour low near $75,946 and a high near $77,622. Holding above the lower boundary would preserve the post-decision recovery structure. A break below it would weaken that setup. Reclaiming the upper boundary would move Bitcoin above Friday’s immediate resistance. Macro policy guidance could still drive volatility.</p>
<p>Governor Kazuo Ueda’s press conference remained the next near-term catalyst on Sept. 18. Markets were watching his guidance on the pace of future increases. The BOJ’s Oct. 1 Summary of Opinions will provide another formal policy signal.</p>
