The embedded "option cost" can be quantified by subtracting the OAS from the Z-spread (which ignores optionality and volatility). Since prepayments typically rise as interest rates fall and vice versa, the basic (pass-through) MBS typically has negative bond convexity (second derivative of price over yield), meaning that the price has more ...
The Z-spread of a bond is the number of basis points (bp, or 0.01%) that one needs to add to the Treasury yield curve (or technically to Treasury forward rates) so that the Net present value of the bond cash flows (using the adjusted yield curve) equals the market price of the bond (including accrued interest). The spread is calculated iteratively.
The "yield spread of X over Y" is generally the annualized percentage yield to maturity (YTM) of financial instrument X minus the YTM of financial instrument Y. There are several measures of yield spread relative to a benchmark yield curve, including interpolated spread , zero-volatility spread , and option-adjusted spread (OAS).
The spread widens because there aren’t high levels of supply and demand, or buy and sell orders to easily match up. The higher transaction cost, in the form of a higher spread, is compensation ...

The interest rate cap can be analyzed as a series of European call options, known as caplets, which exist for each period the cap agreement is in existence. To exercise a cap, its purchaser generally does not have to notify the seller, because the cap will be exercised automatically if the interest rate exceeds the strike (rate). [1]
