Turkey: U.S. Sanctions Under the Countering 
America’s Adversaries Through Sanctions Act 
(CAATSA) 
December 16, 2020 
Turkey’
s July 2019 acquisition of an S-400 surface-to-air defense system from Russia sparked debate 
about possible U.S. sanctions against Turkey—a longtim
e NATO ally—under the Countering America’s 
Adversaries Through Sanctions Act (CAATSA,
 P.L. 115-44). CAATSA requires the President to impose 
sanctions on those persons he determines have knowingly engaged in a “significant transaction” with 
Russia’s security sector. On December 14, 2020, the Administration
 imposed the following sanctions on 
Turkey’
s defense procurement agency, commonly referred to by the Turkish acronym SSB:  
  a prohibition on granting specific U.S. export licenses and authorizations for any goods 
or technology; 
  a prohibition on loans or credits by U.S. financial institutions totaling more than $10 
million in any 12-month period; 
  a ban on U.S. Export-Import Bank assistance; 
  a requirement for the United States to oppose loans benefitting SSB by international 
financial institutions; and 
  full blocking sanctions and visa restrictions on four SSB officials. 
 
I
n a factsheet, the State Department said that the sanctions “are not intended to undermine the military 
capabilities or combat readiness of Turkey or any other U.S. ally or partner, but rather to impose costs on 
Russia in response to its wide range of malign activities.” Additional State Department
 guidance indicates 
that the sanctions do not apply t
o SSB subsidiaries or affiliates.  
Turkish President Recep Tayyip Erdog
an has condemned the sanctions as a “blatant attack” on Turkish 
sovereign efforts to establish an independent defense industry. Additionally, political parties representing 
a large majority of Turkey’s parliament hav
e issued a joint declaration opposing the U.S. decision. 
Turkey’s foreign ministry
 has said that Turkey “will retaliate in a manner and timing it deems

appropriate,” while keeping diplomatic options open. A year ago, Erdog
an threatened to close Turkish 
bases t
o U.S. military personnel and assets in response to potential U.S. sanctions (see
 Figure 1).

After S-400 deliveries began in July 2019, the Trump Administrati
on announced Turkey’s removal from 
t
he F-35 Joint Strike Fighter program, given concerns that the S-
400 could compromise the F-35’s stealth 
capabilities. However, despit
e several difficulties in U.S.-Turkey relations, the Administration delayed 
imposing CAATSA sanctions while unsuccessfully seeking to have Turkey
 replace the S-400 with U.S.-
origin Patriot surface-to-air defense systems. Sanctions have come after Turkey
 test-fired the S-400 in 
October 2020, and shortly after both houses of Congress passed the FY2021 National Defense 
Authorization Act (NDAA
, H.R. 6395). Section 1241 of that bill, if enacted, would direct the President to 
impose CAATSA sanctions on persons he determines have knowingly engaged in Turkey’s S-400 
acquisition. 
Possible Effect of Sanctions 
At this early stage, forecasts vary regarding sanctions’ likely effect on Turkey’s defense industry, while 
generally acknowledging
 some negative effects—at least in the short term—for Turkish exports that rely 
on U.S. components
. One source has said that sanctions would not cancel existing U.S.-Turkey defense 
contracts, but may directly impact around $2 billion of potential business.

According t
o a prominent Turkish analyst, Turkey’s military can directly transact some sales with the 
United States, but the sanctions may handicap U.S.-Turkey—and possibly Europe-Turkey—partnerships 
to develop advanced weapons platforms. Thus, Turkey may face a choice either to get sanctions removed 
or turn to alternative suppliers, such as
 Russia or (perhaps) the United Kingdom for next-generation 
fighter aircraft.  
The sanctions could affect
 Turkey’s economic stability—given the vulnerability of its currency (see 
Figure 2)—if they disrupt the flow of foreign capital that Turkey needs to cover its financial sector’s 
large dollar-denominated debts. The
 early impact on Turkey’s currency has been negligible. The 
Administration did not opt to impose sanctions that could have more directly targeted Turkey’s financial 
system.

The S-400 Issue: Assessment and U.S. Options 
How the United States and Turkey address the S-400 issue may determine how long CAATSA sanctions 
remain in force, and defi
ne Turkey’s relations with the United States and other countries for years to 
come. One analyst
 has proposed that the United States might shelve sanctions if Turkey publicly commits 
not to activate the S-400. Turkey has regularly called for 
a U.S.-Turkey working group to evaluate 
whether the S-400 might operate in Turkey without compromising U.S./NATO assets, but U.S. officials 
have consistently rejected any notion of S-400 coexistence with NATO systems. Under CAATSA (as 
amended by Section 1294 of the FY2019 NDAA
, P.L. 115-232), the President
 may waive or terminate 
sanctions on certain enumerated grounds related to U.S. national security, or impose more sanctions. 
The following factors may affect U.S.-Turkey deliberations on this issue, including under a new 
Administration and Congress: 
  
Turkish domestic developments. What effect might sanctions have on Turkey’s economy, 
defense industry, President Erdogan’s domestic standing, and the breadth of support among 
Turkey’s leadership class and public for the S-400? Erdogan suffered some setbacks i
n 2019 
municipal elections and has

   and could seek to increase his popularity by attributing Turkey’s domestic challenges to U.S. 
sanctions. 
  
Turkey-Russia dynamic. Turkey and Russia each appear to have some form of leverage over the 
other, based on their support for different sides in regional crises i
n Syria, Libya, and 
Armenia/Azerbaijan; their
 bilateral defense and energy cooperation; and Turkey’
s growing 
partnership with Ukraine. Given this dynamic, what might Turkey demand as part of a face-
saving compromise on the S-400? More generally, does this situation present opportunities for 
U.S./NATO common cause with Turkey to counter Russia, or signal greater Turkish distancing 
from NATO on how it deals with Russia?  
  
General U.S. leverage on Turkish foreign policy. How might sanctions, t
he Halkbank case 
pending in U.S. federal court, and S-400 deliberations influence or be influenced by Turkey’s 
regional adventurism, including its confrontational approach with other U.S. partners in the 
Eastern Mediterranean and Middle East? 
  
F-35s and Congress. In the event of a U.S.-Turkey compromise on the S-400, would Congress 
consider amending an existing provision (Section 1245 of the FY2020 NDAA
, P.L. 116-92) that 
currently precludes the transfer of F-35s to Turkey unless it no longer possesses the S-400? 
  
Arms sales to other countries. How might U.S. actions regarding the S-400 issue affect U.S. 
relations with other key partners that have agreed to purchase or may purchase advanced weapons 
from Russia—including
 India, Egypt, and Qatar? In a December 14 press briefing, Assistant 
Secretary of State for International Security and Nonproliferation Christopher For
d said, “We 
hope that other countries around the world will also take note that the United States will fully 
implement CAATSA Section 231 sanctions, and that they should avoid further acquisitions of 
Russian equipment, especially those that could trigger sanctions.”
