Sei price is showing signs of a possible stabilization phase as a new Mastercard partnership puts institutional blockchain adoption back in focus.

At press time, Sei is trading at $0.04005, up 3.78% over the past 24 hours, while derivatives data shows open interest recovering toward $47 million.

Why Is Sei Price Facing Challenges Amid the Mastercard Collaboration Update?

Sei’s latest X post revealed a collaboration between Sei and Mastercard after months of exploring how financial institutions actually evaluate blockchain infrastructure. According to the team, “The foundations of institutional blockchain adoption drop next week.”

The development provides Sei with an essential catalyst, particularly as institutional blockchain adoption becomes a more relevant market theme and market participants continue to look for evidence that blockchain infrastructure can fit institutional requirements. However, based on the price chart, the news has not yet been fully priced in by the market.

What Information Is Conveyed by the Sei Price Graph?

According to data from TradingView, a clear downward trend can be seen in the chart, beginning around $0.07 in June and extending to the current level near $0.04. Sei is also trading below the important $0.04171 level, which is currently the key zone for buyers to reclaim.

The next major resistance level is around $0.05525. A move above $0.04171 would be the first sign of improving bullish momentum, while a break above $0.05525 would indicate a stronger potential trend reversal.

What Is the Relationship Between Sei Price and RSI and MACD?

The relative strength index (RSI) stands at 40.40, below the 50 neutral level but above oversold territory. That reading suggests bearish momentum still has the upper hand, although the recent rise in RSI indicates selling pressure may be easing.

The moving average convergence divergence (MACD) is sending a mixed signal. The MACD line is at -0.00145, while the signal line is at -0.00158, with a slightly positive histogram of 0.00013. That setup may point to an improvement in short-term momentum.

Does Higher Open Interest Support Sei Price Stabilization?

According to Coinglass data, Sei open interest has risen from about $36 million in early August to around $46 million. That suggests growing participation in the derivatives market as traders increase their open positions, a sign that the token is drawing more attention even while spot price remains below near-term resistance.

Volume data shows spikes at certain points, especially on August 14. If increasing derivatives activity is accompanied by a move above $0.04171, the rally would carry more credibility.

What Indicators Should Analysts Watch for Sei Price Dynamics?

The Mastercard collaboration gives Sei another fundamental catalyst, but the technical setup remains cautious. A break above $0.04171 would strengthen the bullish outlook, while failure to clear that level could leave Sei vulnerable to further downside.

The broader setup depends on whether renewed derivatives activity and the institutional adoption narrative translate into sustained buying pressure.
