market's interest bearing token (e.g. wstETH for stETH; in this case PT_TO_SY rate should be used). Technically, interest bearing token is different from standardized yield (SY) token, but since SY is a wrapper around an interest bearing token, we can safely assume the prices of the two are equal. This is not always true for asset price though: using PT_TO_ASSET rate assumes that the yield token can be seamlessly redeemed for the underlying asset. In reality, this might not always be the case.
