             Devaluation

    Presentation to RICS Botswana

               Keith Jefferis
             November 30, 2005




                 Structure
•   The mechanics of exchange rates
•   Exchange rates & competitiveness
•   Why devalue?
•   Impact of devaluation

                                           1
Exchange Rates
• Value of Pula determined in relation to
  basket of currencies (ZAR, SDR) with
  fixed weights.
• Weights reflect trade patterns, changed
  rarely, kept secret
• Exchange rate of pula vs. the basket can
  be changed (=re/devaluation, crawling
  peg)

            Exchange Rates
• Nominal Effective Exchange Rate (NEER)
                 α         β
          BWP   BWP 
               .     =K
          ZAR   SDR 
• weighted average of bilateral exchange rates
• Bilateral exchange rates (e.g. pula-rand) move
  on cross-rates (e.g. rand-dollar)
• Bilateral rate movements (BWP/ZAR,
  BWP/SDR) in opposite directions and cancel
  each other out – hence NEER constant - unless
  re/devaluation

                             Competitiveness
• Real Exchange Rate
                 – Relative domestic and foreign prices adjusted for
                   nominal exchange rate
                                      Pd 

                                             
                 – Competitiveness declines (REER rises) if:
                    • domestic prices rise faster than foreign prices
                    • exchange rate appreciates
                        – Botswana’s problem is the former

Competitiveness
• Botswana prices high relative to trading
  partners/competitors
• Relative prices determined by costs of what is
  produced in Botswana (value added)
• Botswana net costs (= incomes) high relative to
  value of what we produce
• Costs have to be reduced either by reducing
  incomes or increasing productivity


9                                                   9




                   Sectoral effects
• Tradeables (exports or import substitutes)
     –   includes, goods, some services
     –   prices determined internationally
     –   low profits/returns
     –   investment discouraged
• Non-tradeables
     –   most services, property
     –   prices determined locally (high)
     –   high profits/returns
     –   (over) investment encouraged
• Wrong incentives!

                                                         5
Why Devalue?
• Economic growth in Botswana MUST be
  export-led (small domestic market)
• International/historical evidence very clear
  – e.g. China, E. Asia vs. Latin America
• Must be competitive to export
• Exchange rate a crucial determinant of
  competitiveness (along with domestic
  costs)
11                                                    11




          Impact of Devaluation
• Doesn’t higher inflation erode the initial
  impact on competitiveness?
     – only partially – impact on inflation always less
       than 100%
     – e.g. 2004 devaluation of 7.5% added 2%-4%
       to inflation
     – 2005 devaluation of 12% added 4%-5% to
       inflation
     – some competitiveness gains remain
12                                                    12




                                                           6
Impact of Devaluation
• Initial (short-term):
     – Higher import costs (-)
     – Higher inflation (but small effect) (-)
     – Reduced real wages and incomes (-)
     – Profit squeeze in import-intensive sectors (-)
     – Profitability of tradeables sectors improves vis
       a vis non-tradeables (+)
     – Improved international competitiveness (+)
     – Higher government revenues (+)

13                                                    13




          Impact of Devaluation
• Medium term
     – Support for exports and diversification
     – Support for higher economic growth, but
     – Devaluation a necessary but not a sufficient
       condition for higher growth
     – Need to deal with underlying cost factors
     – Crawling peg should eliminate need for further
       devaluations
     – Choices: compete or stagnate
14                                                    14




                                                           7
Impact on Property Sector
• Relative to some other sectors, property likely to
  be disadvantaged, especially in short run
     – devaluation aims to enhance exports & import-
       competing sectors vs. non-tradeables
     – recent over-investment in property
     – now, higher costs, reduced profits
• Medium-long term: higher economic growth will
  support all sectors, including property



15                                                     15




“There is a strong association between
[growth] acceleration episodes and trade.
Episodes are correlated with strong growth
in the economies of a country’s trading
partners, export growth, and a competitive
real exchange rate. Exports were also
facilitated by REER depreciations …. pointing
to the importance of careful management of
competitiveness regardless of the exchange
rate regime” (IMF, 2005, Sustaining Growth
Accelerations and Pro-poor Growth in Africa)
