Despite a recent decline in popularity, Power Reverse Dual Currency notes continue foreign currency options investopedia exist on many books due to the strengthening of the JPY foreign currency options investopedia. Therefore accurate pricing of Power Reverse Dual Currency notes remains an important, yet foreign currency options investopedia, endeavor for both issuers and investors worldwide. During the mid 's, the Japanese interest rate market suffered a sharp decline in yields.
These movements caused Japanese investors to start searching for structured products that gave higher yield than available domestically. They had to look elsewhere, in foreign interest rate markets where there was a significant interest rate differential. The first incarnation was a principal protected note, denominated in yen, but paying a coupon that referenced that foreign currency. These notes, whose coupons were typically floored at zero, were referred to as Reverse Dual Currency RDC notes and could effectively be thought of as a strip of foreign exchange coupons.
The instruments used in the calibration should be as similar as possible to the instrument being valued. For example, to value a Bermudan swaption that is exercisable beginning five years from today to nine years, into a swap with maturity ten years from today, you would use European swaptions with the following maturities: Another example would be an American exercise callable bond maturing in 10 years that can be exercised starting today.
Some sample European swaptions to use would be: Additional criteria that should be considered is that some of the instruments used for calibrating may not be actively traded instruments stale quotes.
For what constitutes good calibration, please see below. For calibration using caps and floors the inputs that are required are caplets and floorlets. The idea of leverage was introduced to the notes and the Power Reverse Dual Currency was born.
The different methods of producing this leverage resulted in a wide variety in the types and characteristics of Power Reverse Dual Currency notes.
As a first measure to increase yield, the notes were given extremely long nominal tenor years are common from a desire to access the increasing yield further out in the curve. However, investors typically believed that the notes would be called back immediately following the non-call period.
This period is non-callable, however typically the notes are Bermudan callable, meaning that the issuer retains the right to call back the note at any cash flow date. To further increase yield, an additional parameter was added to the coupon formula, the "FX base". This parameter scales the FX rate used in the coupon formula and foreign currency options investopedia usually set to be equal to foreign currency options investopedia FX forwards seen in the market at the time of issue.
Mathematically, this changes the slope of the coupon payoff thereby adding foreign currency options investopedia to the product. A increase of the FX rate above that predicted in the forward market a weakening of the JPY currency increases the coupon and a decrease of the FX rate a strengthening of the JPY currency decreases the coupon. In today's climate of historically low interest rates, Power Reverse Dual Currency notes may yet experience a resurgence in popularity as investors again undertake the "search for yield".
However, during the recent global credit crunch, all markets have seen a drastic increase in volatilty, including the FX and interest rate markets. This has caused an increase in the magnitude of the daily hedging of PRDC notes, most of which has been at a loss to the issuing institution.
The early exercise date is calculated using the Longstaff-Schwartz algorithm, and is expected to exhibit more variance than the fair value. This accounts for the observed scatter in the expected duration in figure 1. From the above considerations, investors in Power Reverse Dual Currency notes can be thought of as taking a view on the forward FX market.
The general economic thinking was foreign currency options investopedia the JPY currency would not appreciate more than the FX forward market, however, if it did this would signal a rally in the JPY economy and it would cease to be a low yield environment.
Up tothe JPY currency essentially followed the forward. However, it began to appreciate against the USD in causing a decrease in Power Reverse Dual Currency coupons, meaning investors were left holding long dated extremely low-yielding instruments! Counter-intuitively, this was actually not entirely favourable to the issuers either - hedging such long dated structures is done in the long end of the FX forwards and options markets, which are very illiquid and therefore the hedges prove to be costly.
For these reasons, accurate pricing of Power Reverse Dual Currency notes using model sufficiently complex to incorporate the long dated FX options market data is invaluable for both investors and issuers.
Although the notes are primarily exposed to the foreign exchange rate, the arbitrage-free dynamics of the FX rate. One could imagine a model where the dynamics of the interest rates are frozen being satisfactory for an FX-linked product of short duration, however this type of approximation will not be sufficient for Power Reverse Dual Currency notes due to their long tenor that this is only a nominal tenor and not expected duration is not important, as issuers will always need to hedge FX options out to the longest maturity possible.
Equally as important as the choice of model, is the choice of model parameters. They must be foreign currency options investopedia to reflect the current market data. With a relatively complicated model, this can become quite cumbersome. The procedure used is outlined uses two novel techniques: Markovian projection and parameter averaging. These techniques are outlined in [ 3 ].
Foreign currency options investopedia Power Reverse Dual Currency coupons can be described by the following formula. The parameters f and d are referred to as the foreign and domestic coupon respectively, foreign currency options investopedia nomenclature arising from the fact that d is multiplied by the domestic notional, whereas f must first be multiplied by the prevailing FX rate prior to being multiplied by the domestic notional. The parameters a and b refer to the coupon floor usually set to zero and cap, respectively.
The second type of coupon structure handled by FINCAD Analytics Suite is the "digital" or "step-up" coupon, where the coupon structure is a piecewise constant function of the underlying FX rate - in other words the coupon is constant but experiences jumps to a different constant level when the FX rate reaches specific values.
The other important feature of Power Reverse Dual Currency notes are their call feature.
