WINDHOEK, July 24 (Xinhua) -- Namibia's central bank has unveiled the country's upgraded banknotes and new coinage series featuring enhanced security measures and updated designs.

President Netumbo Nandi-Ndaitwah presided over the unveiling ceremony Wednesday evening.

The event coincided with the official celebration of the 35th Anniversary of the Bank of Namibia (BoN), which was themed "Anchored in Stability: 35 years of central banking excellence and innovation."

The upgrade represents the first change to Namibia's coins since their introduction in 1993 and the first update to its banknotes since 2012.

"Change is, therefore, long overdue, because technological advances have progressed, and Namibia must stay on par with the rest of the world," Nandi-Ndaitwah said.

She highlighted the alignment of the banknotes and coins with international best practices through adjustments to their sizes and materials.

"I encourage all Namibians to familiarize themselves with the new features and to embrace this milestone with pride and shared responsibility," the president said. "It is a living symbol of our unity, resilience, and aspirations."

The new banknote and coin family consists of five banknotes and five coins.

BoN Governor Johannes Gawaxab told the launch that the coins are lighter, smaller, and more durable, making everyday transactions easier and more efficient.

"Instead of depicting Namibia's fauna and flora, the new coins now symbolically represent the five key sectors that anchor Namibia's economy," he said.

The central bank said the new currency series will officially enter circulation in August, alongside the current series, to ensure a smooth and seamless transition.

"To support the public in recognizing and adapting to the new features, the bank will be conducting a comprehensive, countrywide awareness campaign," Gawaxab said.
