Triggering: \Magento\Framework\Locale\Currency::getCurrency()

magento/magento2/blob/2.1.0/lib/internal/Magento/Framework/Locale/Currency.php#L92-L98


$options = new \Magento\Framework\DataObject($options);
$this->_eventManager->dispatch(
    'currency_display_options_forming',
    ['currency_options' => $options, 'base_code' => $currency]
);


$currencyObject->setFormat($options->toArray());

Handling: \Magento\CurrencySymbol\Observer\CurrencyDisplayOptions::execute()
