U.S. equity futures edged higher in early European trade on Tuesday. Concurrently, Japan's yen fell to a 40-year low against the U.S. dollar, intensifying traders' expectations of possible government intervention.

The weakening yen against the dollar has been a persistent trend, prompting close observation from financial markets and policymakers. The currency's significant decline raises concerns about its potential impact on global economic stability and trade dynamics. The current movement suggests a sustained pressure on the yen, leading market participants to anticipate actions from Japanese authorities aimed at stabilizing the currency.
