The zloty triumphs. The Swiss franc is down significantly, the dollar is also losing

The zloty wins the last week of March. This is especially visible towards the Swiss franc and the US dollar.

The biggest loser of the week is the Swiss currency, which loses as much as 3.69 groszy in relation to the Polish zloty. The dollar also ends the week in negative territory, although the scale of the decline is much smaller.

The euro remains almost stable and records only a symbolic withdrawal. In turn, the pound sterling is the only one to clearly defend its position, ending the week with a slight increase. The five-day balance is therefore favorable for the zloty – especially against the franc and the dollar.
