From the United States Embassy in Athens:
Security Message for U.S. Citizens: Banking Disruptions in Greece
June 28, 2015
The State Department alerts U.S. citizens residing in or traveling to Greece of the possibility of disruptions to banking services – including credit-card processing and servicing of ATMs – throughout Greece in light of developments within the local economy. International and local media are reporting that banks will remain closed starting on Monday, June 29, 2015, and that capital controls may be imposed before they re-open. U.S. citizens are encouraged to carry more than one means of payment (cash, debit cards, credit cards), and make sure to have enough cash on hand to cover emergencies and any unexpected delays.
The State Department recommends you maintain a high level of security awareness and avoid political rallies and demonstrations as instances of unrest can occur. Exercise caution and common sense: Avoid the areas of demonstrations, and if you find yourself too close to a demonstration, move in the opposite direction and seek shelter. Even demonstrations intended to be peaceful can turn confrontational and possibly escalate into violence.
The U.S. Embassy maintains a website with information about anticipated demonstrations, rallies, and strikes. We encourage all U.S. citizens to review their personal security plans, remain aware of their surroundings, including local events, and monitor local news stations for updates. U.S. citizens should maintain a high level of vigilance and take appropriate steps to enhance their personal security. Exercise vigilance to protect against pickpocketing and secure valuables in hotel rooms when traveling. For additional information, please refer to “Travelers Checklist.”
U.S. citizens traveling to or residing in Greece are encouraged to enroll in the Department of State’s Smart Traveler Enrollment Program. By enrolling, U.S. citizens make it easier for the Embassy or nearest Consulate to contact them in the case of an emergency. U.S. citizens without Internet access may register directly with the U.S. Embassy in Athens.
