Oanda Swap Trading: up to -90%?

What the hell is going on with your swaps??? Other brokers are fine. You have swaps on GBP/CHF up to -14.97% !!!
You have swaps up to -90% on some currencies on long and short side!!

Does anyone knows what's going on here??

Here is an excerpt from yesterday:
you can find the quotes here:
https://www.oanda.com/rw-en/trading/financing-costs/ (just scroll down and choose 27th of December)

Today the quotes are better but again a weird occurance:

EUR/HUF: 27th of December short: +8.66% (Dukascopy 15%)

EUR/HUF: 28th of December short: -12.53% (Dukascopy 15.6%) and because of Wednesday it is for even 4 days !

GBP/PLN: 27th of December short: -24.16%

GBP/PLN: 28th of December short: +7.15% , what??? Spread of 31% in one day.

I'm not sure if I like that behaviour. I cannot always adapt to new crazy swaps and change always my bigger positions.

@JackintheBox. Did you figure out what is going on?
