Bvisa zvinhu zvinopesvedzera chimiro chechimiro chechibereko, uye uzvinyore uchishandisa mabara.
Context:Makumbo anobereka anowanzokwira kumusoro asymptotically: iyo yakareba nguva yekukura, iyo yakakwirira chibereko, nekuderedza kuwedzerwa kwemuganhu (ndiko kuti, sezvo mumwe achienda kurudyi, curve inoputika kunze). Maererano nomunyori wenhau Buttonwood wepepanhau rinonzi The Economist, kutsvedza kwechikamu chinobereka mari chinogona kuyerwa nomusiyano, kana kuti "kupararira", pakati pemari inobereka mari yeU.S. Treasury Notes yemakore maviri negumi. Kupararira kwakakura kunoratidzira mutserendende wakanyanyisa.  Pane tsananguro mbiri dzinozivikanwa dzomupendero wokukwira wemichero. Chokutanga, zvingava kuti misika iri kutarisira kukwira kwechikamu chisina ngozi. Kana varimi vakarega kuisa mari zvino, vangagamuchira mwero uri nani munguva yemberi. Nokudaro, maererano nedzidziso yemitengo ye arbitrage, vatengesi avo vanoda kuisa mari yavo zvino vanofanira kubhadharwa nokuda kwekukwira kunotarisirwa kwemitengo - nokudaro mari yepamusoro yemari yekutsvaga kwenguva refu. Imwe tsananguro ndeyokuti nguva refu yekupera inopa njodzi huru kumusimari (kureva mukweretesi). Mutengo unoda mari inobhadharwa panjodzi, sezvo nguva yakareba ichireva kusava nechokwadi kukuru uye mukana mukuru wezviitiko zvine zvazvinoita pakudyara. Tsananguro iyi inotsamira papfungwa yokuti upfumi hunotarisana nezvisingazivikanwi zvakawanda munguva yemberi iri kure kupfuura munguva pfupi. Izvi zvinozivikanwa se "liquidity spread". Kana misika ichitarisira kuwedzera kusagadzikana mune ramangwana, kunyange kana mitengo yemari ichitarisirwa kuderera, kuwedzera kwemutengo wezvipingamupinyi kunogona kukanganisa kupararira uye kukonzera kuwedzera kwemari.  Mamiriro ezvinhu anopesana anogonawo kuitika, umo mubereko wemubairo unenge "wakashandurwa", nemitero yemari yenguva pfupi yakakwirira kudarika yenguva refu. Somuenzaniso, muna November 2004, mubereko wemabhondi ehurumende yeUnited Kingdom wakanga watendeuka zvishoma. Kubudirira kwebhondi remakore gumi kwakamira pa4,68%, asi kwaingova 4,45% yebhondi remakore makumi matatu. Kutarisira kwemusika kuderera kwemitengo yemari kunoparira zviitiko zvakadaro. Negative liquidity premiums inogonawo kuvapo kana vatengesi venguva refu vachitonga pamusika, asi maonero akakurumbira ndeokuti kuwedzerwa kwemari yemari kunotonga, saka kungotarisira kuderera kwemitengo yemari kunokonzera kutendeuka kwemigumisiro. Zvikwereti zvinodzoserwa zvakanyanyisa zvakatangira kuderera kwezvemari munhau.  Chimiro chechikwereti chinobereka chinokanganiswa nechipo uye kudiwa: somuenzaniso, kana pane chido chikuru chezvisungo zvenguva refu, somuenzaniso kubva kune mari yepenjeni kuti ienzane nezvikwereti zvavo zvisingagumi kune vanochengetwa, uye kwete zvikwereti zvakakwana zviripo kuti zvizadzise chido ichi, ipapo zvibereko zvezvisungo zvenguva refu zvinogona kutarisirwa kuva zvakaderera, pasinei nemaonero evatambi vemusika pamusoro pezviitiko zvenguva yemberi.
- Zvinotarisirwa nemusika pamwero wemari yomunguva yemberi. Kana vanoisa mari vachitarisira kuti mari yemari ichakwira mune ramangwana, zvinobva zvaita kuti curve yacho iite seiri kukwira. Zvikasadaro kana musika uri kutarisira kuderera kwemari yemari, ipapo curve yaizova yakaderera. - Ruzha rwakawedzerwa. Nguva refu yekupera inopa njodzi dzakakura kumusimari, saka varimi vangatarisira kudzoka kwakakwirira kwezvikwereti zvenguva refu. - Kupa uye kuda. Kana paine kudiwa kwakanyanya kana kuti kupiwa kwakaderera kwezvisungo zvine nguva yakatarwa, ipapo mhindu yezvisungo izvozvo yaizoderera.
