When computing option prices one needs an "interest rate", which I usually take as zero, or rather the rate I would get for a savings account in US dollars. It used to be near-zero, right?
But recently I saw I'm getting 3.5% for 1 year deposits at the local bank! Checking US deposit rates on the internet though is very inconsistent, I see both 0.01% (what I used to consider as "the rate") and rates as high as 5%.
So which one is it?
Also if 5%, and ignoring the inflation ... doesn't this invalidate quite a few trading systems? I mean getting 5-10% consistently with low risk and high Sharpe used to be pretty good (at least that's what a lot of people were saying they'd be happy to) but still, in finance there's always risk. So now it's just better to pull out of stocks and just deposit your money in the bank, safe and guaranteed win.
