Common Use Cases
Currency Exchange Rate Analysis
Example input prompt:
What’s the current USD/EUR spot rate, and what are the 3-month and 6-month
forward rates? Calculate the implied forward points for each tenor.
When to use: Evaluating currency positions, pricing FX forwards, or analyzing currency basis.
Tip: Compare spot vs. forward rates to understand market expectations for currency movements.
Interest Rate Curve Comparison
Example input prompt:
Show me the USD SOFR swap curve. Plot the curve and identify any unusual
shapes or inflection points.
When to use: Assessing interest rate risk, pricing swaps, or understanding monetary policy expectations.
Typical analysis: Compare curves across different currencies or time periods to identify relative value opportunities.
Multi-Currency Bond Analysis
Example input prompt:
Price the following bonds using their ISIN codes: FR0014012I5 (French
government bond) and US91282CNT44 (US Treasury). Compare their yields and
calculate the spread.
When to use: Portfolio construction, relative value analysis, or credit assessment across sovereign issuers.
Note: Ensure proper currency conversion when comparing international bonds.
FX Forward Curve Construction
Example input prompt:
For AUD/USD, show me the complete forward curve using AONIA and SOFR
conventions. Display the forward points and implied forward rates for
standard tenors.
When to use: Structuring FX derivatives, pricing swaps, or analyzing currency carry strategies.
Works well with: Custom valuation dates to assess forward pricing at specific points in time.
Cross-Asset Correlation Analysis
Example input prompt:
Get the USD SOFR curve and EUR ESTR curve, then analyze how they’ve moved
relative to each other. Are there any divergences that suggest trading
opportunities?
When to use: Identifying cross-currency basis trades or understanding global rate relationships.
Key benefit: LSEG provides consistent data across asset classes for reliable correlation analysis.
Real-Time Market Data for Trading
Example input prompt:
I’m looking at pricing a currency swap. Get me the current EUR/USD spot
rate and the EUR ESTR and USD SOFR curves for accurate valuation.
When to use: Pre-trade analysis, pricing verification, or mark-to-market calculations.
Why it matters: Real-time access ensures your analysis reflects current market conditions.
Tips for Using LSEG
Use specific currency pair conventions (USD/EUR, GBP/USD)
Specify tenors clearly for forward rates (3M, 6M, 1Y)
Reference bonds by ISIN codes for accurate pricing
Define valuation dates when working with forward curves
Understand curve conventions (SOFR, ESTR, AONIA) for different currencies
Cross-reference data across tools to validate analysis
