The currency devaluation trick is : tzun zu "appear weak If you are strong " art of war
Turkey been keeping rates low in order to invest in military and now turkey is one of most powerful country in Europe.
Everybody was talking about turkey when lira was falling... But nobody did not pay attention to the fact that If country lowering the currency they might be up for something.
Now russia currency aswell falling for the same reason wich is keeping rates low and currency value low so this way they can finance war and military.
If we look at 3 countries Poland, Turkey , Russia their monetary policy show's clearly they use lower rates to finance their military.
Now all the world talking about weak russian currency but nobody don't pay attention If country currency is that much low then this country might be very dangerous for other countries.
The lower rates can give huge financial power.
You refer to Sun Tzu, but fail to realize when the situation is actually beyond the control of or indirectly caused by the poor economic actions of the leaders of both countries. They have not skillfully navigated themselves into these positions, where their currency is super weak, but have through sheer incompetence engineered their own downfall. The Turkish Lira imploded because Erdogan tried to interfere with central banking functions and go against all the best advice that was presented, which required a painful but necessary adjustment, because he wanted a win at an upcoming election. Putin failed because he did not understand the huge backlash that came with invading Ukraine and some of the most extreme measures ever enacted against another country to isolate it from the richest trading partners in the world. Both were down to very poor leadership.
