6 Back in May 2022, [[file:monetary policy and mortgage products][I made a bet]]
7 Australian house prices would decline relative to Belgian ones, and the
8 Australian cash rate wouldn't grow as high as the Euro-zone one. On that
9 day, the RBA had lifted the Australian cash rate from the historical low
10 of 0.10% to 0.35%. Today, that rate stands at 4.10%, with the latest
11 increase in a series of 12 having happened at the start of June 2023 -
14 The European central bank in the mean time has raised its main
15 refinancing operations rate 9 times since July 2022 from 0% to 4.25% at
16 the start of August 2023, an increase of 4.25%pt.
18 Both the Australian and the Belgian government have statistical offices
19 publishing median house prices. The way these are tracked varies
20 slightly between the countries. In Belgium, Statbel publishes median
21 prices for 3 types of residential dwellings every quarter, and the
22 corresponding number of transactions that happened for each of these.
23 The Australian Bureau of Statistics on the other hand publishes a median
24 residential dwelling price every month, which is based on a
25 stratification by dwellings type taken from the census which happens

32 Of course, the AUD/EUR exchange rate needs to be taken into account as
33 well. I've adjusted the prices using the weighted average monthly
34 exchange rate. This way, we can compare the price evolution in a way
35 that takes into account the evolving difference in purchasing power
36 between the currencies of the 2 nations.

42 Comparing the first 3 months of 2021 to the first 3 months of 2023, the
43 relative price of an Australian residential dwelling has gone to 92% of
44 what it was when compared to its Belgian equivalent. If the starting
45 point is Q1 2022, just before the rates started going up, the difference
46 is an even starker 16% relative decline in price!
48 So far, both bets seem to have been correct - house prices in Australia
49 have significantly gone down relative to the Belgian ones since the
50 interest rate hikes started, and the cash rate in Europe, which started
51 slightly lower than the one in Australia, has already surpassed it.
