Hello, Is Matlab able to calculate the SABR model for negative interest rates? Or is it necessary to make adjustment to the model. Is Matlab making adjustments, so making available the shifted SABR or free boundary SABR models?

Hi,
Good question as the current rates trend are goind negative. I do not find anything of the financial toolbox on interest rate working (as log normal distribution do not work anymore)! Maybe there will need a new release or you should update your model on your own. Regards,
