Crypto Liquidity Falls as Stablecoin Outflows Hit $3B Ahead of BOJ, FOMC Meetings

Crypto market liquidity is tightening ahead of two major central bank decisions, with stablecoins recording more than $3 billion in outflows this week and pushing the total stablecoin market capitalization to a near two-month low of $316 billion. The figure is more than $6 billion below the late-May peak of $322 billion, according to data cited in market reports.

Attention is focused on the Bank of Japan's upcoming policy meeting, scheduled for June 15–16. Markets are currently pricing in a 97% probability of a 25-basis-point rate hike. Japan's consumer price index rose to 113 points in April, up from 112 points in March, according to TradingEconomics, keeping inflation pressure on the BOJ to consider further tightening. USD/JPY has climbed back toward 160 after four straight weeks of gains, a move that has revived concerns about stress in global liquidity conditions.

Every major BOJ rate hike since 2024 has triggered a sharp correction across the crypto market, a pattern analysts have flagged as the BOJ decision approaches. The BOJ meeting will overlap with the upcoming FOMC meeting, a combination that market participants are watching closely even though no Fed rate hike is currently priced in. A less dovish tone from either central bank could amplify volatility in risk assets including crypto.

Higher Japanese rates would tend to strengthen the yen and reduce the flow of cheap yen-funded liquidity that has historically supported risk assets. With stablecoin market cap already down sharply from its late-May high and broader risk sentiment described as risk-off, the setup has been characterized by analysts as a major liquidity test for the crypto market, though the direction of any subsequent move remains to be determined by the policy decisions and incoming economic data.
