JAKARTA – In a bold move designed to shield its economy from the messy unpredictability of the outside world, Indonesia’s central bank has announced a sweeping new policy that effectively declares the nation’s financial system immune to global events. The rupiah, officials stated, will now derive its value primarily from the collective good vibes of the Indonesian people.

“For too long, our currency has been held hostage by distant conflicts, commodity prices, and whatever Elon Musk tweeted last night,” declared Bank Indonesia Governor Perry Warjiyo, reportedly while burning a map of the Middle East and a printout of the Dow Jones Industrial Average. “No more. The rupiah will now float freely on a sea of national pride, delicious street food, and the unwavering belief that everything will eventually sort itself out.”

Under the new regulations, foreign exchange transactions will be subject to an “optimism surcharge,” with higher rates applied to those exhibiting any signs of global economic anxiety. Analysts are scrambling to understand the mechanics. “So, if I’m worried about inflation, my dollar-rupiah conversion gets worse?” pondered Dr. Anya Sharma, a bewildered economist at the Jakarta School of Economics. “It’s either genius or… well, it’s certainly something.”

Sources close to the central bank suggest future policy moves could include mandatory daily affirmations for traders and a national holiday dedicated to collective positive thinking. The government hopes this will create a “self-sustaining loop of financial serenity.”
