Which exchange reopened in 1990 after being closed for 41 years?

The Shanghai Stock Exchange reopened in 1990 after being closed for 41 years.

Shanghai had an earlier securities market, but trading was suspended after the establishment of the People's Republic of China in 1949. As China introduced economic reforms in the late twentieth century, authorities created new capital-market institutions.

The modern Shanghai Stock Exchange was established on November 26, 1990, and began trading on December 19 of that year. The 41-year gap refers to the period between the closure of the earlier Shanghai exchange in 1949 and the reopening of the modern market in 1990.

Shanghai is one of China's two principal stock exchanges on the mainland, alongside the Shenzhen Stock Exchange. The Shanghai market is especially associated with large state-owned and established companies, while Shenzhen has historically had a stronger presence of smaller and technology-oriented firms. The Shanghai Composite Index is a widely followed measure of shares traded there.
