Simultaneous interest rate hikes may cause global liquidity to shrink, and crypto-market volatility will intensify
Global monetary policy is currently going through a confusing period, with the European Central Bank (ECB), Bank of Japan (BOJ) and the Federal Reserve Board (Fed) all preparing to enter a tightening cycle. This change could lead to a significant redistribution of liquidity within the financial system. This shift is significant for cryptocurrency investors because cryptocurrency markets have historically been extremely sensitive to liquidity, lending rates and risk appetite around the world.
It is reported that the European Central Bank has raised interest rates by 25 basis points this month, and discussions about the Bank of Japan raising interest rates further by 25 basis points are also increasing. At the same time, the market generally expects the Federal Reserve to have a high possibility of raising interest rates.
Previously existing spreads had made yen-denominated capital easily available and used to invest in areas such as bonds, stocks, real estate and cryptocurrencies. If the tightening cycle enters simultaneously, this supporting effect will be weakened and financing costs will rise, prompting investors to reduce their positions in risky assets. In times of financial distress, larger cryptocurrencies with active ecosystems, high liquidity, and mature market participation may perform very differently than smaller, more speculative tokens.
In this context, the following five asset categories are worthy of attention: Aptos (APT), Sui (SUI), Sei (SEI), Ethereum (ETH) and Hedera (HBAR).
Aptos (APT): Facing the test of a high interest rate environment
Aptos (APT) is closely connected to the broader Layer-1 market, which means its performance can be highly dependent on liquidity and investor preference for high-beta assets. A tightening monetary environment may increase volatility, while a warming risk appetite may attract buyers back into a mature blockchain ecosystem.
Sui (SUI): Focus on Observation of the Layer-1 Market
Sui has grown into one of the most popular new generation Layer-1 networks. It is in a sensitive area where traders switch between main-chain cryptocurrencies and high-risk altcoins, so it is very sensitive to changes in the flow of funds. As a result, liquidity conditions will continue to have a significant impact on Sui.
Sei (SEI): Reflecting changes in risk appetite
Sei is another network where sharp price fluctuations may occur due to global liquidity contraction. Its market behavior will increasingly depend on trading activity, ecosystem growth, and whether investors continue to allocate capital to smaller Layer-1 projects during periods of tightening monetary policy.
Ethereum (ETH): Occupying a unique position
Due to its size, liquidity and role in decentralized finance (DeFi), Ethereum (ETH) occupies different market positions. If widespread risk aversion emerges in global markets, ETH may still face selling pressure. However, its mature infrastructure distinguishes it from smaller altcoins in terms of market characteristics.
Hedera (HBAR): Join the macro liquidity discussion
Hedera (HBAR) may not be removed from the watch list, as investors weigh blockchain networks with solid enterprise-level narratives. However, its price will still be affected by overall market conditions, so in the short term, the retreat of market liquidity will dominate the development dynamics of individual networks.
