Which pair of countries launched the common cross border digital currency Aber?

Introduction / Context:
Central banks across the world have been experimenting with digital currencies to make cross border payments faster and more efficient. One such project involved a joint digital currency named Aber, launched as a pilot by two Gulf region central banks. General awareness questions often ask candidates to identify which pair of countries cooperated on this initiative, because it combines knowledge of international finance, central bank policy and Middle East geography.

Given Data / Assumptions:

• The digital currency mentioned is called Aber.
• The question asks which countries launched this common digital currency.
• Options describe pairs of countries: UAE and Saudi Arabia, Saudi Arabia and Iraq, Iraq and UAE, Malaysia and UAE.
• We assume the question refers to the joint project announced by the central banks in the Gulf region.

Concept / Approach:
The currency Aber was a joint initiative of the central banks of the United Arab Emirates and Saudi Arabia. It was designed primarily as a cross border settlement currency between the two countries using distributed ledger or blockchain technology. Other countries listed in the options, such as Iraq and Malaysia, are not part of this specific digital currency project. Therefore, the correct approach is to recall that Aber is associated with a UAE Saudi Arabia partnership and choose the option that names both countries together.

Step-by-Step Solution:
Step 1: Identify that Aber is a collaborative digital currency project rather than a national fiat currency.Step 2: Recall that the central banks involved were those of the United Arab Emirates and Saudi Arabia.Step 3: Look at the options and find the pair that matches exactly this combination.Step 4: Select UAE and Saudi Arabia and discard the distractor pairs that include Iraq or Malaysia.

Verification / Alternative check:
Official statements from the central banks and coverage by international financial news agencies clearly state that Aber was launched as a common digital currency project by the United Arab Emirates Central Bank and the Saudi Arabian Monetary Authority. These sources explain that it was intended for financial settlements between the two countries on a pilot basis. Any exam oriented current affairs compilation that covers digital currency developments will repeat that Aber is a joint project of UAE and Saudi Arabia, confirming this pairing as the correct answer.

Why Other Options Are Wrong:
Saudi Arabia and Iraq are neighbours in the region but Iraq was not part of the Aber project, so that pair is incorrect. Iraq and UAE also excludes Saudi Arabia, which was central to the initiative, and therefore cannot describe the actual joint currency. Malaysia and UAE suggests a partnership between Southeast Asia and the Gulf, but Malaysia does not appear in the official announcements regarding Aber. Since Aber specifically involved only the UAE and Saudi Arabia, any other combination is factually wrong for this question.

Common Pitfalls:
One common mistake is to focus only on the presence of Saudi Arabia or UAE in an option and not check the full pair carefully, leading to confusion between similar sounding choices. Another pitfall is mixing Aber with other digital currency projects or with generic rumours about many countries trying cryptocurrencies. To avoid this, students should link the word Aber with just two countries, United Arab Emirates and Saudi Arabia, and treat that association as a fixed memory item for exams.

Final Answer:
The common digital currency Aber was jointly launched by the central banks of the United Arab Emirates and Saudi Arabia, so the correct option is UAE and Saudi Arabia.
