USD/TRY: A Case Study in One-Way Risk and Policy Shocks
The Turkish lira has been among the weakest major emerging currencies in recent years, and USD/TRY illustrates risks that differ from those of ordinary pairs.
Long-run depreciation has been driven by high inflation, unorthodox interest rate policy, and concerns about central bank independence. A pair that moves persistently in one direction attracts traders who see easy profit from the trend, but the trade has hidden dangers.
Swap costs are large. Being long the dollar against the lira means earning large positive swaps in many periods, but brokers often charge heavy markups, and the cost structure can reverse unexpectedly.
Spreads are very wide, and liquidity can vanish suddenly during stress. Sharp moves in either direction can occur on policy announcements or political developments, including sudden central bank decisions that move the pair hundreds of points within minutes.
Brokers sometimes raise margin requirements or restrict trading in such pairs without much notice. Some have limited position sizes or closed trading entirely during volatile periods.
The trend may look persistent, but being on the wrong side of a policy reversal can be costly, and stops may slip heavily.
Treat such currencies as high-risk instruments, with smaller sizes and an awareness that the cost of carry and spread can be large relative to the expected move.
Practical step: check your broker's margin requirement and maximum position size for USD/TRY, and calculate the cost of holding a position for one month.

Re: USD/TRY: A Case Study in One-Way Risk and Policy Shocks
The one way chart looks like easy money, and that's the trap. Spread, swap markups and sudden margin changes can eat the trend, and one policy surprise can take back months. What people forget is that a long USDTRY position fights the swap in many periods, because lira rates have often been far above dollar rates. So you pay every night while you wait for the trend to deliver. Then a surprise rate hike or intervention can knock the pair down sharply in minutes. Before touching it, I'd work out the weekly swap cost at your size and compare it with the move you expect. Often the maths alone is enough to say no.

Read your broker's notices before holding it. Some brokers have changed margin or restricted it during stress with very little notice, and you don't want to find out with a trade open. A margin increase on a pair you're already holding can push your free margin down suddenly, and if the account is tight, positions can be closed automatically at a bad price. If you do trade it, keep the account well funded relative to the position, keep the position small, and check the broker's email and platform messages every day. Exotic pairs with policy risk are exactly where brokers protect themselves first, and you're the one on the end of that.
